benefits of vitamin c


After decades of ridicule and denial, the theories of early vitamin C researchers are finally gaining acceptance in the mainstream medical community. Dr. Fredrick Klenner, whose extensive vitamin C research in the 1930s was largely scorned, observed that “some physicians would stand by and see their patient die rather than use ascorbic acid (Vitamin C), because in their finite minds it exists only as a vitamin.”

Dr. Klenner, as well as other researchers like Linus Pauling, used vitamin C to treat a mind-boggling array of health conditions, including supposedly incurable ones. Though their work is still considered controversial, modern research has confirmed the therapeutic efficacy of ascorbic acid in a wide variety of medical contexts, including hormone regeneration, cancer, heartburn, stomach ulcers, anti-aging skincare, stress relief, sepsis, heart disease, and more.

But some researchers believe that vitamin C deserves even more credit. Viewing it as a therapeutic agent, they argue, still implies that it is “only a vitamin,” rather than an integral and essential part of biological homeostasis in humans.

To understand their point of view, it’s necessary to take a brief tour of human evolution.

The connection between vitamin C production and biological balance

If it sounds a bit strange or overblown to consider vitamin C a fundamental aspect of the body’s self-regulating biology, consider this fact: humans are one of only a few species that do not endogenously produce ascorbic acid (vitamin C). Nearly all mammals (and nearly all vertebrates, for that matter) have a built-in biological mechanism for producing ascorbic acid, which acts as a hormone regulator, modulates the immune system, and protects the body against acute stressors.

Furthermore, humans lost the ability to synthesize vitamin C internally due to what is referred to as a genetic metabolic defect—some researchers even go so far as to state that humans have an “inborn vitamin C deficiency,” for which they must compensate in order to remain healthy.[1]

More conservative researchers claim that the genetic mutation responsible for the loss of vitamin C synthesis is a neutral trait (in genetics, a trait is considered neutral when its loss is neither advantageous or disadvantageous). They contend that the importance of exogenous vitamin C is already highlighted by the fact that its RDA is higher than any other vitamin (60 mg/day), and that a normal diet provides the average person more than enough vitamin C.

There’s a couple facts that suggest that diet is not sufficient to provide us with ample vitamin C, though (especially if we want to enjoy its more acute therapeutic benefits).

For example, while researching the correlation between vitamin C concentrations within certain organs and elite athleticism, one doctor realized that the “optimal” vitamin C concentrations would be very difficult to achieve with an RDA of 60 milligrams (the current recommended daily allowance of vitamin C).[2]

Further, vitamin C is used up much more quickly in individuals who smoke tobacco or drink alcohol, in the presence of toxins, and in states of physiological and emotional stress. Thus, even if 60 mg/day is a sufficient baseline dose of vitamin C, it’s likely that our bodies are using it to fight toxins and stress rather than optimizing overall biology.

Given the chronic vitamin C depletion that these ideas suggest, the nearly miraculous reversals of disease states that high-dose vitamin C can facilitate begin to make more sense. What improvements in health and wellness could we all enjoy if vitamin C deficiency was addressed with simple supplementation?

How to start benefiting from vitamin C today

All the researchers and physicians who successfully used ascorbic acid as a therapeutic agent did so by mimicking the endogenous vitamin C production of other mammals—that is, they dramatically raised blood serum levels of vitamin C very quickly (one study found that goats produce nearly 13,000 mg of vitamin C every day, and that this production level increases by almost 10 times in a matter of hours when the animal is placed under acute stress).[3]

To do this requires very specific routes of administration—taking a few of those orange-flavored chewable vitamin C tablets isn’t going to cut it.

Until quite recently, intravenous administration of vitamin C was the most tenable approach. While it’s certainly still viable, the method has its obvious drawbacks: it’s expensive, requires appointment scheduling and doctor supervision, and often is a time-consuming process. Besides, there’s not many people who are willing to deal with intravenous needles just to get their dose of vitamin C.

Thankfully, it’s now possible to raise your blood serum levels of vitamin C at home, safely and affordably, with a simple liquid vitamin C supplement. Two formulation methods—known as micellar and liposomal encapsulation—have revolutionized vitamin C supplementation by raising the bioavailability of ascorbic acid to levels approaching that of intravenous administration.

If you’d like to find the best vitamin C supplement to include in your own regimen, look no further than PuraTHRIVE. They offer the only vitamin C available that’s delivered with both micelle and liposomal encapsulation—this patented, two-part formulation method protects ascorbic acid from breakdown, ensures optimal nutrient utilization, and even enhances the already impressive antioxidant activity of vitamin C.

Give it a try today, and experience how much better the body functions when provided with an optimal quantity of this essential nutrient.

After decades of being grossly underrated, vitamin C is beginning to move back into the spotlight. Research demonstrates that this humble nutrient offers benefits far beyond the prevention of scurvy, thus vindicating the writings of early pioneers like Linus Pauling.

In past articles, we’ve detailed how vitamin C fights cancer and improves survival rates, fights heartburn and stomach ulcers, keeps skin radiant and wrinkle-free, provides immediate stress relief, allows for recovery from advanced sepsis, and improves cardiovascular health.

In the 1940s, Dr. Fredrick Klenner followed in Linus Pauling’s footsteps by using vitamin C as a therapeutic agent in his medical clinics—with mega-doses of vitamin C, he claims to have cured his patients of pneumonia, encephalitis, Herpes zoster (shingles), Herpes simplex, mononucleosis, pancreatitis, hepatitis, bladder infections, alcoholism, arthritis, cancer, leukemia, atherosclerosis, ruptured intervertebral discs, high cholesterol, corneal ulcers, diabetes, glaucoma, schizoprenia, burns, infections, heat stroke, radiation burns, heavy metal poisoning, venomous bites, multiple sclerosis, chronic fatigue, and more.

The work of both Linus Pauling and Dr. Klenner is quite controversial. They have routinely been referred to as quacks, and are only just beginning to regain favor. As you can see from the article links above, though, there’s more than enough conclusive research to support vitamin C’s healing and health-supporting potential, regardless of your stance on these original vitamin C enthusiasts.

One important area that has vitamin C researchers especially interested is endocrine support.

Vitamin C can regenerate hormones, study finds

As we’ve discussed in past articles, hormone and endocrine dysfunction is a serious and prevalent health issue. Hormones are fundamentally involved in the regulation of the body’s cells, neurotransmitters, and organs. Thus, endocrine imbalance can lead to a staggering array of health problems, including fertility issues, chronic fatigue, cardiovascular issues, depression, anxiety, and other neuropsychiatric disorders, diabetes, cancer, and many others.

Luckily, research suggests that vitamin C can offer powerful endocrine support. In one prominent study, researchers set out to explore the mechanisms through which vitamin C may prevent the breakdown of hormones into toxic metabolites. The results were even more impressive than they expected: vitamin C was shown not only to prevent hormone degradation, but also to regenerate estrone, progesterone, and testosterone.[1]

These findings have remarkable implications. They expand our understanding of vitamin C as an antioxidant, insofar as they demonstrate that ascorbic acid not only neutralizes free radicals, but also prevents the analogous production of “hormone transients.”

This mechanism is especially important because it highlights vitamin C’s potential use as a safe alternative to hormone replacement therapy (which is inconsistently effective, and tends to make the problem worse by making the body dependent upon an external source of hormones).

Lastly, this study strengthens the case for vitamin C as a potent protector against the toxins of modern living. The endocrine system is centrally involved in the body’s detoxification functions; thus, by supplying the body with vitamin C, you’re exerting a direct antioxidant influence and optimizing the body’s inherent detox system.

How to supercharge hormone healing

There’s just one catch when it comes to reaping the benefits of vitamin C: high blood serum levels are required, so it can be difficult to get enough vitamin C from food sources alone, or even through conventional supplementation.

Until fairly recently, the only way to achieve therapeutic blood serum levels of vitamin C was by receiving it via intravenous injection. This is still a worthwhile route of administration, but it’s expensive and time-consuming—not to mention ill-advised for those who don’t have the stomach for needles.

The development of a nanoencapsulation method called liposomal delivery, however, has made it safe, easy, and affordable to supplement with vitamin C optimally, without needles or doctor appointments.

Liposomalization sounds complicated, but it’s simple in concept: this formulation process uses phospholipids (fats) to form a sort of protective bubble around vitamin C molecules. The lipid layer protects vitamin C against breakdown and allows it to be utilized directly by the cells in your body.

There are a handful of companies offering liposomal vitamin C products, but we exclusively recommend this one by PuraTHRIVE.

They’ve raised the bar even higher by using a patented “double-encapsulation” method called micelle liposomal formulation. Micelles further increase absorption, ensure that your cells can utilize vitamin C optimally, and even improve the antioxidant capacity of vitamin C.

It should go without saying that you should still eat lots of healthy foods rich in vitamin C, even in the midst of your supplementation regimen. Optimal nutrition should always be the foundation of a healing lifestyle or specific therapeutic protocol—after all, “supplements” are referred to as such because they’re meant to supplement, not replace, food sources of nutrients.

Combined with a healthy diet, though, micelle-liposomal vitamin C is the fastest and easiest way to enhance the incredible hormone-healing benefits offered by vitamin C.

It’s no secret that mainstream oncology is in desperate need of new treatment strategies. Cancer is now the second leading cause of death in the United States. In this year’s “Annual Report to the Nation on the Status of Cancer,” analysts warned that while overall cancer mortality rates have decreased, our progress is “very limited.”[1]

Meanwhile, the incidence of cancer continues to increase every year, at a rate that some experts believe eclipses the decline in mortality rates.

Chemotherapy and radiation therapy still dominate the landscape of cancer treatment, and despite the trust that mainstream doctors place in them, they’re far from perfect. In numerous past articles, we’ve outlined their dangers and limitations.

A wealth of research now demonstrates that many functional foods and natural remedies perform on par with chemotherapy without any of its side effects (they also ameliorate negative effects when used in conjunction with conventional treatments). Prominent examples include turmeric and ginger, but you can also check out the full list of top cancer-fighting foods here.

The road of reforming oncology will be a long and bureaucratic one, but new possibilities are beginning to gain traction. One natural cancer fighter that’s increasingly proving its worth is vitamin C.

If you’ve read any of our past vitamin C articles, you already know that we’re big believers in its healing capacities. We’ve said it before, and it’s worth saying again: vitamin C is one of the underrated and underutilized nutrients in existence.

Luckily, researchers are finally putting it to work against one of America’s biggest killers.

Vitamin C fights cancer from every angle

Conventional cancer treatments function according to a simple principle: remove or kill cancer cells at all cost. And sadly, the cost is usually exorbitant—tumor removal surgeries are invasive and risky, and both chemotherapy and radiation therapy kill much more than just cancer cells.

Natural cancer fighters like vitamin C are different. Throughout every stage of its metabolism in the body, vitamin C helps battle cancer in unique ways. Instead of working via the “shotgun” approach of killing cancer cells, ascorbic acid targets them directly, without harming your body’s normal, healthy cells. It also works with your body to boost natural immunity and cancer-fighting capacity.

Let’s look at a more detailed exploration of why vitamin C is such a perfect ally for those battling cancer.

Inflammation reduction. Chronic inflammation underlies a large number of chronic and degenerative diseases, and cancer is no exception. In fact, one study even refers to inflammation as “a key event in cancer development.” The researchers report that oncologists can predict the survival chances and timelines for cancer patients solely based on inflammation biomarkers, and that patients with the lowest levels of inflammation are expected to live up to two years longer, even in the absence of conventional treatment.[2]

High-dose vitamin C improves two of the most prominent inflammation biomarkers, pro-inflammatory cytokines and C-reactive protein tumor markers.[3] Lower levels of inflammation also allow your immune system to focus its energy on fighting cancer (rather than maintaining inflammatory response).

Cancer cell gene mutation. Vitamin C also directly targets cancer cells with remarkable accuracy. When researchers looked more deeply into how ascorbic acid is able to kill cancer cells, they found that it’s able to exploit a genetic mutation shared by many cancer cells.

Due to this mutation, the uptake of vitamin C and its metabolites deactivates an enzyme necessary for processing glucose, thus effectively starving the cancer cell.[4] This incredible specificity allows ascorbic acid to destroy cancer cells without harming healthy cells.

Reactive oxygen species. In an attempt to explain how vitamin C exhibits such impressive selectivity (i.e. the ability to target a certain type of cell while leaving others untouched), researchers also discovered that even the metabolites of vitamin C are toxic to cancer cells. Vitamin C easily breaks down into hydrogen peroxide, a reactive oxygen species against which normal cells can easily protect themselves—cancer cells, on the other hand, will absorb the hydrogen peroxide and be weakened or killed by oxidative stress.[5]

How to experience the benefits of high-dose vitamin C

During most of the studies cited above, vitamin C was administered intravenously. While an increasing number of doctors and clinicians are offering IV vitamin C therapy to the general public, the process can be expensive, time-consuming, and invasive. It has been the choice of mainstream doctors and researchers, despite these drawbacks, due to its superior bioavailability compared to oral supplementation.

Fortunately, a category of drug delivery methods known as liposomes is finally making it possible to achieve high blood levels of vitamin C without resorting to injections.

Research demonstrates that liposomal vitamin C approaches the bioavailability of intravenous administration,[6] and evidence suggests that a combination of micelle and liposome encapsulation may even surpass the efficacy of IV vitamin C.

New Purathrive Micelle Liposomal Vitamin C encapsulates natural vitamin C in a phospholipid sphere – a tiny bubble made from lecithin – called a ‘liposome.’

Because regular vitamin c pills, liquids and foods have an upper limit of bioavailability due to absorption speed and the amount that could be handled by your digestive system without causing irritation and diarrhea… Purathrive Liposomal C is buffered so you can absorb more through the gut.

If you want feel the benefits of vitamin C, we suggest trying out PuraTHRIVE’s new micelle liposomal formula. It’s even made with l-ascorbic acid, a fermented form of ascorbic acid that more closely resembles natural, plant-derived sources.

It’s estimated that up to 70 million Americans suffer from digestive diseases. A full 25 million will experience a gastic ulcer at some point in their lives, and over 60 million (that’s 20% of the entire U.S. population) experiences acid reflux symptoms at least once weekly.[1]

And the worst part? The incidence of chronic digestive disorders is still rising sharply, especially in the United States.

We shouldn’t really be surprised. The Standard American Diet is a poor excuse for actual nutrition—its meat, sugar, and processed foods inevitably lead to inflammation, oxidative stress, and digestive imbalance. After all, the stomach is the front line of your body’s battle against toxic and unhealthy food.

To make matters worse, our core treatment modalities for digestive issues are woefully inadequate and short-sighted. Rather than seek out the root causes of stomach issues, we employ drugs that temporarily mask symptoms (and ultimately make the condition worse in the long-run).

Take common antacids also known as proton pump inhibitors (PPIs), for example. These dangerous drugs, which are now available everywhere as over-the-counter medications, are our primary treatment for conditions ranging from heartburn (acid reflux and GERD) to stomach ulcers.

Doctors continue to use them despite a growing awareness that lowering the stomach’s acid content actually worsens and perpetuates the underlying condition.

One editorial in the journal Gastroenterology literally claimed that “proton-pump inhibitor therapy induces the symptoms it is used to treat,” even in healthy individuals who had never experienced acid reflux prior to taking the medication![2]

Steer clear of antacids like Nexium, Prilosec, and Prevacid… these medications have been conclusively linked to both Alzheimer’s disease and liver dysfunction

And in case you still need more reasons to steer clear of PPIs like Nexium, Prilosec, and Prevacid, know that these medications have been conclusively linked to both Alzheimer’s disease and liver dysfunction.

While optimal diet and lifestyle modification should always be your first course of action, we also need to seek out remedies that safely attack the root causes of digestive issues. New research suggests that vitamin C may be just the supplement for the job.

The bacteria that’s attacking your stomach
(and how vitamin C fights it)

In another article, we outlined vitamin C’s exceptional antibacterial qualities. According to one hospital physician, it’s so powerful that it outperforms our strongest antibiotics, and decreases the mortality rate of septic infection from 50% to 1%.[3]

So what does this have to do with digestive issues?

Quite a bit, because it turns out that bacteria are a root cause behind at least some of the digestive disorders plaguing us today. In particular, researchers have been studying the Helicobacter pylori bacterium (H. pylori), which is linked to gastric ulcers and heartburn.

H. pylori is a hugely prevalent bacterium—it’s estimated that 50% of the entire world’s population is infected with it.[4] It is easily passed like any other germ, but it usually doesn’t take hold unless a person’s gut flora and stomach acidity are already imbalanced. You’re particularly at risk if you eat inflammatory foods, take NSAIDs like ibuprofen, or take PPIs.

You read that right: proton-pump inhibitors increase the risk of H. pylori infection. Nevertheless, PPIs are the primary treatment (along with antibiotics) for gastric ulcers—just like with GERD, they worsen the very condition they’re used to treat.

Luckily, when vitamin C is added into the mix, the results are dramatically improved. The eradication rate of H. pylori that occurs with antibiotics and PPIs is only 60% (a figure considered insufficient by gastrointestinal specialists), while adding 1,000 mg of vitamin C and 800 IU of vitamin E to the regimen yielded an eradication rate of 91%. Further studies have demonstrated that vitamin C helps clear persistent H. pylori infection even in the absence of antibiotics and other pharmaceuticals.[5]

Maximize the benefits of vitamin C

Vitamins in general have gotten a bad rap—mainstream media outlets have attacked them as nothing more than ineffectual marketing gimmicks. Nevertheless, research has clearly demonstrated that vitamin C can be a powerful ally to your health, as long as you follow a couple rules for maximizing its benefits.

First, steer clear of multivitamins and synthetic vitamin C capsules packed with additives and artificial flavors. These products are largely a waste of money, because hardly any ascorbic acid is absorbed when you take them.

Instead, seek out a high-potency formulation that is nanoencapsulated for optimal bioavailability. Choose l-ascorbic acid, which is a fermented form of ascorbic acid that mimics the form of vitamin C that naturally occurs in plants (and in the bodies of mammals that produce the nutrient endogenously).

If you’re looking for an exemplary vitamin C that checks all these boxes, we highly recommend PuraTHRIVE Liposomal Vitamin C.  Using high-grade l-ascorbic acid, and their patented micelle liposomal encapsulation increases absorption by up to 140 times. It’s by far the most powerful (and delicious) vitamin C product on the market.

We’ve written at length in the past about the wonders of vitamin C. This super-nutrient is making big waves in the medical community; even mainstream medicine is beginning to acknowledge that it’s capable of much more than preventing scurvy.

In fact, it’s becoming clear that vitamin C plays a central role in the body’s self-defense processes—defense against pathogens, oxidative stress, and even the ravages of aging. And our symbiotic relationship with vitamin C has been a pivotal one since the dawn of our evolution. At one time, our bodies even manufactured ascorbic acid endogenously to combat perceived threats (this is a talent still enjoyed by many animals).

Given vitamin C’s affinity for safeguarding our health, it should come as no surprise that it holds great potential as an anti-aging aid. In past articles, we’ve explored how vitamin C can ward off or help heal serious illnesses, including (but most certainly not limited to) cancer, heart disease, sepsis, and infection (both viral and bacterial).

But there’s another, more “surface-level” anti-aging benefit that vitamin C can provide: radiant skin health.

Are your wrinkles a sign of vitamin C deficiency?

Before we dive into exactly how vitamin C protects the health and beauty of your skin, let’s talk a bit about vitamin C deficiency.

Beyond preventing scurvy, conventional medicine hasn’t had much to say about the importance of avoiding vitamin C deficiency. But the tide is turning: a growing body of research is demonstrating that by depriving your body of optimal vitamin C levels, you may be at risk for adverse health effects long before scurvy sets in.

To illustrate, consider this point: the minimum daily RDA of ascorbic acid for preventing scurvy is 46 mg/day (the “optimal” RDA is 65 mg/day, barely any higher than the minimum).[1] Meanwhile, researchers have found that many mammals will naturally produce over 10,000 milligrams of ascorbic acid every day. When these animals are faced with an acute pathogen or stressor, their bodies can produce over 200,000 milligrams in a single day to combat the threat.

Given that our bodies used to have this same innate capacity, can you imagine the benefits we may be missing out on by only providing our bodies with a measly 65 milligrams of vitamin C per day?

While exceedingly few people would recommend taking 200,000 milligrams of vitamin C in a single day, there are an increasing number of experts that see vitamin C as a tool for safeguarding health and slowing the aging process, especially when taken in higher doses (at least 1,000 mg per day).

For example, given vitamin C’s role in collagen production (more on that below), there’s reason to believe that maintaining optimal levels can help prevent the wrinkles and other skin deterioration associated with aging.

If you don’t eat enough fruits and vegetables on a daily basis, are a smoker or drinker, or deal with even a moderate amount of stress on an ongoing basis, you should be especially vigilant about avoiding vitamin C deficiency (and the skin issues that come along with it).[2] By eating and supplementing properly, you can enjoy some incredible skin benefits (in addition to the many other benefits provided by vitamin C).

Here’s just a few reasons why vitamin C is your skin’s best friend.

Collagen production. As mentioned above, ascorbic acid is critical for your body’s production of collagen, the protein that keeps skin cells young and healthy. For this reason, vitamin C is always present in both the dermis and epidermis, where it functions as an antioxidant and collagen regulator.[3] Studies have shown that oral supplementation of vitamin C will increase levels in the skin, thus increasing the skin’s ability to ward off oxidative stress.[4]

Protection against sun damage. The antioxidant capacity of vitamin C (particularly when it’s present in optimal levels in the skin) has been shown to limit the damage caused by UV exposure.[5] Unlike sunscreen, which blocks the absorption of UV light (and impedes the skin’s synthesis of vitamin D), vitamin C simply minimizes the negative oxidative stress that UV rays can cause. Vitamin C certainly isn’t a replacement for responsible sun exposure, but it can help reduce the skin damage that can occur from spending too much time in the sun.

Wrinkle prevention. One of the most dreaded effects of oxidative-stress-induced skin aging is the development of wrinkles. Researchers now understand that age-related wrinkles can be eased and minimized simply by controlling the oxidative stress and collagen levels of the skin. Vitamin C accomplishes both tasks in one swoop: it protects against free radical damage and keeps collagen strong and abundant through a process called hydroxylation. Studies have shown that optimal skin levels of vitamin C can reduce wrinkles, reduce protein fiber damage, decrease the roughness of the skin, and increase collagen production.[6]

How to get the most out of vitamin C

As with any nutrient, optimizing vitamin C levels begins with proper nutrition; any supplementation regimen should be built on a foundation of plenty of nutrient-dense fruits and vegetables (guava, oranges, red peppers, kale, and broccoli are great common food sources of vitamin C).

That being said, supplementation is the fastest and easiest way to glean the full benefits of vitamin C. There are many topical skin care products that contain vitamin C, but oral supplementation is still the wisest choice. As mentioned above, oral supplementation will increase levels of vitamin C in the skin, while providing all the other benefits that come from having high blood levels of vitamin C (using it topically won’t suffice for attaining higher blood levels).

High bioavailability is essential, so always be sure to supplement with a properly formulated vitamin C product like this one. PuraTHRIVE’s micelle liposomal vitamin C is a cutting-edge formulation of l-ascorbic acid (a fermented form of ascorbic acid that is more naturally “recognized” by the body).

It’s nanoencapsulated through two delivery methods for maximum absorption (micelle and liposomal delivery), and it’s absolutely delicious. Give it a try today to find out why vitamin C is the latest buzz in the natural health community.

Vitamin C is making a serious comeback. As we’ve discussed in past articles, researchers of the early to mid 20th century became obsessed with the seemingly miraculous healing capacities of high-dose ascorbic acid (the technical name for vitamin C). The work of these pioneers was largely shunned by the mainstream medical community, however, and vitamin C returned to its status as “just another vitamin.”

More recent research has begun to restore vitamin C to its former glory, though, with many experts wondering whether the vitamin-C-optimists of the 1940s were right all along.

One prominent study demonstrated that intravenous vitamin C dramatically outshines even the strongest antibiotics for treating sepsis—one doctor found that it reduced the mortality rate of his sepsis patients from as high as 50% to a mere 1%.[1]

Other studies have found that vitamin C is an invaluable tool for fighting cancer. It works through a wide variety of healing mechanisms (none of which carry the horrendous side effects of chemotherapy and radiation treatments), and has been shown to be effective against cancers of the ovaries,[2] pancreas,[3] prostate, bladder, skin, breast, lung, thyroid, and more.[4]

And that’s just a few impressive examples of what modern researchers have been discovering about vitamin C. It’s becoming increasingly clear that vitamin C is highly underestimated, and that it deserves a prominent place in mainstream medicine. It doesn’t just prevent scurvy, but also can act as a powerful tool for treating serious illness and reclaiming the health of the whole body.

And now another, somewhat unexpected benefit has been added to the list of vitamin C’s marvels: natural stress relief.

How vitamin C lowers cortisol levels and manages stress naturally

For some time, researchers have been fascinated by the connection between vitamin C and physical performance optimization. They’ve observed that vitamin C perfectly supports the body before, during, and after physical exertion—and even that supplementing daily with vitamin C can confer the same cardiovascular benefits as exercise.[5]

Over the course of these studies, researchers something very interesting: high-dose vitamin C supplementation consistently reduces levels of cortisol, adrenaline, and other markers for heat-induced stress[6] during high-intensity exercise.[7] Since these chemicals are linked with the body’s overall stress response (physiological or otherwise), could vitamin C also attenuate psychological stress response?

The answer is a resounding yes. German researchers carried out a randomized controlled trial and published their results in the journal Psychopharmacology. They subjected study 120 study participants to acute psychological stress using what’s called the Trier Social Stress Test (which consists of on-the-spot mental arithmetic and public speaking). Half of the group was given 1,000 milligrams of ascorbic acid (vitamin C) before the test, and half was given a placebo.

The vitamin C group displayed improved markers of psychological stress across the board: lower systolic blood pressure, lower diastolic blood pressure, lower levels of the stress hormone cortisol, faster cortisol salivary recovery (meaning that cortisol spikes associated with acute psychological stress recovered to baseline more quickly), and more favorable subjective stress response to the test.

Those who were given vitamin C even reported that they felt “less stressed” right after taking it. This stands to reason, as previous research discovered that administration of high-dose vitamin C literally halts the secretion of cortisol in animals.

And because cortisol is one of the primary hormones through which your body modulates stress response, controlling it with vitamin C represents a promising step forward in the treatment of stress and anxiety.

How to begin your own vitamin C regimen

As you can probably see by now, everyone can benefit from vitamin C supplementation. This incredible nutrient played a prominent role in the evolution of our immune systems—our bodies used to manufacture its own supply of ascorbic acid to fight pathogens, inflammation, and oxidative stress (many mammals still have this built-in mechanism).

Due to what researchers call an “inborn error of carbohydrate metabolism,” our livers now contain an enzyme that blocks the synthesis of vitamin C. One fascinating study does claim, however, that human adrenal glands secrete small amounts of vitamin C as part of the body’s natural stress response,[8] but it’s nowhere near the level that our livers used to produce.

Regardless, you can still tap into this natural state of healing through supplementation.

Not all vitamin C supplements are created equal, though. To experience results like those discussed above, you’ll need to take a high-quality, high-bioavailability product. Otherwise, most of the ascorbic acid will simply pass through your body without being absorbed (this is the case with the vast majority of vitamin C products, and is the reason why the mainstream media is so pessimistic about the benefits of vitamins).

For this reason, liposomal vitamin C is the way to go: it’s the only route of administration that’s nearly as absorbable as intravenous injections, and it’s much cheaper, more convenient, and less invasive. We recommend PuraTHRIVE’s product, which is nanoencapsulated using two cutting-edge formulation techniques, liposomal and micellar delivery. It’s the highest-potency vitamin C available on the market, and unlike other products, it’s delicious!

Of all the nutrient deficiencies discussed, vitamin C is certainly not the most common. It’s almost invariably associated with scurvy, a condition characterized by mood imbalance, connective tissue defects, rashes, impaired wound healing, and even internal bleeding.

Scurvy occurs in circumstances of dire malnutrition—such conditions are still endured in developing countries, and sailors historically struggled with it (because vitamin-C-rich fruits and vegetables couldn’t be preserved onboard during long voyages). But surely it’s no longer a concern in the developed world?

Is vitamin C deficiency more common than we think?

Scurvy is admittedly a state of extreme deficiency, and one which is very uncommon, especially in the United States. Less than 20,000 cases of scurvy are reported annually in the United States, and it’s estimated that only around 6% of the population has ever suffered from the condition (probably from a combination of nutrient-poor diet and preexisting medical issues that interrupt the process of nutrient absorption).

As recently as 2016, though, major media outlets like the BBC reported that scurvy may be making a comeback in the developed world—hospital admissions related to scurvy increased 27% between 2009 and 2014.[1] This may not seem like much, but it’s an important reminder that vitamin C deficiency is still worthy of our concern.

If you don’t eat enough fruits and vegetables, routinely fast or engage in restrictive dieting, have a medical condition like Crohn’s disease or ulcerative colitis that inhibits nutrient absorption, use drugs or alcohol frequently, or smoke, you should be especially careful. These factors place you at high risk for vitamin C deficiency, so consider supplementing with a high-bioavailability vitamin C product (and altering your lifestyle habits whenever possible).

Here’s a quick checklist of vitamin C deficiency symptoms to watch out for:

  1. Frequent illness and other signs of poor immune function.

  2. Fatigue

  3. Depression and other mood imbalances.

  4. Joint pain and inflammation

  5. Rashes, dryness, and other skin issues

  6. Dry and brittle hair and nails

  7. Periodontal issues such as swollen or bleeding gums

  8. Easy bruising and slow wound healing

  9. Frequent nosebleeds

Even if you’re not currently experiencing any of these symptoms, though, don’t write off vitamin C just yet. Research into the mechanisms of this amazing nutrient are beginning to redefine the terms of deficiency. Due to the complex and multi-faceted role that vitamin C plays in the body, individuals can suffer the effects of insufficient vitamin C long before any symptoms begin to present (and certainly before they progress to full-blown scurvy).

And because of its seemingly miraculous healing capacities, having anything less than optimal levels of vitamin C (and thus missing out on its incredible benefits) is its own brand of deficiency.

We’ve certainly encountered this issue with other nutrients, such as vitamin D. Our government-approved RDAs (recommended daily allowances) are often woefully low, because they target only the level necessary to prevent severe deficiency.

Fortunately, a growing number of health experts are starting to speak out about the power of optimizing our nutrient levels, rather than simply meeting our body’s barebones requirements. Dr. Mark Moyad, M.D. speaks particularly highly of vitamin C, claiming that “vitamin C may be the ideal nutrition marker for overall health. The more we study vitamin C, the better our understanding of how diverse it is in protecting our health, from cardiovascular, cancer, stroke, eye health [and] immunity to living longer.”[2]

There’s lots to love about vitamin C

Dr. Moyad is the latest in a long line of vitamin C enthusiasts. In a past article, we covered the research of Dr. Fredrick Klenner, who in the 1940s used high-dose vitamin C to cure a staggering number of serious diseases, such as leukemia, cancer, Herpes simplex infection, schizophrenia, multiple sclerosis, and even physical ailments like ruptured intervertebral discs.

Dr. Klenner’s work remains controversial to this day, but modern research is nevertheless revealing that vitamin C can be profoundly healing for a wide variety of health conditions, from sepsis to cancer to heart disease. This is because of its profound antioxidant capacity—fighting the free radicals generated by oxidative stress is centrally important for maintaining overall health and preventing disease.[3]

And here’s the best part: you can enjoy the many benefits of vitamin C easily and inexpensively. Always start with food, and don’t overthink it. While there’s some foods that are especially rich in vitamin C—like guavas, black currants, red and green peppers, kiwis, oranges, strawberries, papayas, broccoli, kale, parsley, and Brussel sprouts—you’ll do just fine as long as you eat a varied, colorful diet with lots of fruits and vegetables.

Once your body has a good foundation of food-sourced vitamin C, you can unlock the more acutely therapeutic benefits of this nutrient through supplementation.

==> Also seek out liposomal vitamin C, which is dramatically more absorbable (and thus more effective) than any other type of formulation. Studies have even shown that oral supplementation with liposomal vitamin C approaches the absorption capacity of intravenous administration.[4]

For all its wonders, modern medicine still has its limitations—perhaps even more than we usually like to admit.

Serious infections provide a window of insight into these limitations; one glance at medical statistics is enough to remind us that even our most powerful antibiotics and most cutting-edge interventions are sometimes helpless in the face of highly virulent bacteria and viruses.

Sepsis—a bacterial infection of the blood—is perhaps one of the most dire kinds of common infection. The condition afflicts over a million Americans every year, and a shocking 28-50% of all sepsis patients die from it (this is more than the number of deaths from prostate cancer, breast cancer, and AIDS combined).[1]

The symptoms of sepsis can escalate to life-threatening severity very quickly. Sensing the gravity of the situation, the body often is triggered into systemic inflammation, which can lead to a cascade of events that cause organ failure and other debilitating effects.

For these reasons, it’s critical to treat sepsis with fast-acting measures. Intravenous antibiotics are the main line of defense we have, and they have major drawbacks.

You might remember from our previous articles that antibiotics are extremely hard on the body. They indiscriminately kill bacteria (including the good bacteria that critically support for vast array of bodily functions), hamper the immune system, and increase the risk of antibiotic resistance (wherein bacteria mutate into stronger, more deadly versions of themselves).

Antibiotics also do little to address the systemic inflammation and oxidative stress that accompany sepsis.

All of these risks might be acceptable if antibiotics were a guaranteed measure against sepsis. As evidenced by the statistics above, though, this is not the case. An increasing number of physicians recognize that the risks posed by antibiotics are untenable, given that up to 50% of sepsis patients still lose their lives.

Until recently, though, there were very few viable alternatives, and doctors were left with no option but to administer high-dose antibiotics and hope for the best. In 2016, however, one doctor discovered that intravenous vitamin C may be exactly the sepsis treatment for which the medical world has been searching.

A humble vitamin with miraculous results

Prior to 2016, researchers had already explored the mechanisms by which vitamin C can reduce sepsis mortality.[2]

Dr. Paul Marik of Sentara Norfolk General Hospital tested the validity of their findings when faced with a nearly hopeless case of sepsis. A 48-year-old women under his care in the ICU was facing almost certain death—a severe case of sepsis had already caused her kidneys and lungs to shut down.

In a final attempt to save her life, Dr. Marik administered an intravenous mixture outlined by previous research: vitamin C, thiamine (vitamin B1), and corticosteroids (to ease the inflammation caused by rampant immune response). Amazingly, the treatment worked, and by the next morning it was clear that she would enjoy a full recovery.

Dr. Marik’s success sparked a string of trials and studies over the past year, all of which have yielded very promising results. Dr. Marik reports that the administration of intravenous vitamin C lowered the mortality rate of his sepsis patients to 1 percent.[3]

These findings have been supported by subsequent studies,[4] and one review confirmed that corticosteroids are not the ingredient that provide the greatest benefit (and that steroids can actually be counterproductive for sepsis treatment when administered without vitamin C).[5]

While some experts are still skeptical, Dr. Marik’s work has inspired a great deal of enthusiasm overall. A “sepsis treatment protocol for medical professionals” has now been posted online by the Eastern Virginia Medical School, and many experts are urging that further research be conducted.[6] And unlike many alternative medical treatments, IV vitamin C treatment for sepsis has already been featured and shared across many mainstream media platforms.

Vitamin C is massively undervalued

This discovery is great news for vitamin C, and hopefully leads to a reevaluation of the vitamin’s potential. As we’ve covered in past article, vitamin C is tremendously underutilized as a natural medicine. Over the years, a string of independent physicians have discovered its ability to treat a wide variety of illnesses, including many supposedly incurable ailments.

Unsurprisingly, the findings of these vitamin C pioneers were ridiculed and dismissed into obscurity. With Dr. Marik’s clinical findings already gathering momentum, though, it seems that mainstream medicine may final start to believe in the untapped capacities of vitamin C.

And don’t think that vitamin C is only useful for treating sepsis and preventing scurvy—it offers a wealth of potential benefits to nearly anyone. Integrating a vitamin C supplement into your daily regimen dramatically boosts the immune system, supports heart health, increases physical performance, and can even ward off cancer.

An increasing number of doctors offer in-office intravenous vitamin C treatments, in case you want to experience it in its most direct form. These injections can be costly, though, and research has demonstrated that liposomal vitamin C is every bit as absorbable.

Always do your homework before purchasing liposomal vitamin C, though—only buy products that use “true” liposomes, and avoid GMO lecithin and toxic additives. We think that PuraTHRIVE’s new micelle liposomal vitamin C is the best on the market: it’s affordable, optimal potency, and absolutely delicious.

As we’ve written about before, vitamin C is a highly underestimated medicine.

While it’s common knowledge that this essential nutrient will boost the immune system and prevent scurvy, a growing body of research is showing it’s still not given nearly enough credit.

Scientists have discovered that most mammals—with the exception of monkeys, guinea pigs, and humans—naturally produce vitamin C (ascorbic acid) within their bodies.[1] This endogenous vitamin C functions as a sort of supercharged extension of the immune system, warding off nearly any illness that comes the animal’s way. This might very well be the reason why so few animals in the wild fall ill.

Most mammals naturally produce vitamin C.  But unlike mammals humans lack the ability to make Vitamin C

Humans used to have this same ability, but due to what researchers call an “inborn error of carbohydrate metabolism,” our livers now contain an enzyme protein called L-gulonolactone (GLO) that blocks ascorbic acid synthesis.[2]

Some experts believe that this mechanism simply became unnecessary because of a diet rich in vitamin C. If this is the case, though, why don’t our diets and vitamin C capsules endow us with super-healing abilities?

It seems that it’s a matter of dosage.

The current RDA for vitamin C is 90 milligrams—a paltry amount compared to the 13,000 milligrams that goats and other mammals endogenously produce daily (and they produce much greater amounts when placed under stress).[3] 90 milligrams will prevent scurvy, but that’s it.

The real magic of Vitamin C begins at higher daily doses.

In the 1940’s, a doctor named Fredrick Klenner demonstrated that high doses of vitamin C (up to 300,000 milligrams a day) successfully combat a vast array of serious and even supposedly incurable conditions.

His list is a shocking one: pneumonia, encephalitis, Herpes zoster (shingles), Herpes simplex, mononucleosis, pancreatitis, hepatitis, bladder infections, alcoholism, arthritis, cancer, leukemia, atherosclerosis, ruptured intervertebral discs, high cholesterol, corneal ulcers, diabetes, glaucoma, schizoprenia, burns, infections, heat stroke, radiation burns, heavy metal poisoning, venomous bites, multiple sclerosis, chronic fatigue, and more.

Needless to say, Dr. Klenner’s work was dismissed as quackery, and the medical mainstream is only beginning to reconsider the miraculous healing potential of vitamin C. One area in which it shows great promise is cancer treatment.

Wide-spectrum cancer support

High-dose vitamin C therapy is a not a new method. Linus Pauling, a Nobel Prize-winning doctor and scientist, used vitamin C to treat cancer successfully as early as the 1930’s—but he too was written off the medical community.

New research is beginning to clear his legacy, however. Within the past five years, vetted studies have conclusively demonstrated that, in sufficient doses, vitamin C can be immensely helpful in the treatment of cancers of the ovaries,[4] pancreas,[5] prostate, bladder, skin, breast, lung, and thyroid, as well as B-cell lymphoma.[6]

While the mechanisms by which vitamin C aids cancer treatment are myriad, these studies primarily focused on two: the suppression of inflammation and the destruction of cancer cells with a specific genetic mutation.

As you’ve most likely heard before, most experts agree that inflammation is at heart of nearly every major illness—and cancer is no exception. In fact, chronic inflammation is one of the primary markers for cancer; higher levels of inflammation always signal both a higher risk of developing cancer and a lower chance of recovering from the condition.

Oncologists can literally predict survival chances and times based on inflammation biomarkers—

Oncologists can literally predict survival chances and times based on inflammation biomarkers—patients with the lowest inflammation levels are twice as likely to live for at least two years after cancer diagnosis.[7]

This is because inflammation hampers the body on every level; it stifles the immune system (and thus the body’s ability to fight cancer), increases the prevalence of oxidative stress (a key risk factor for the development and spread of cancer), and even aids the initiation and metastasis of tumors.

High-dose vitamin C therapy ameliorates this issue by significantly lowering levels of both pro-inflammatory cytokines and C-reactive protein tumor markers, while boosting the immune system and lessening the negative side effects of chemotherapy in the process.[8]

And vitamin C can also directly kill cancer cells, particularly those with a specific mutation in KRAS and BRAF genes. Cells with this mutation have an increased tendency to transport the oxidized form of vitamin C, dehydroascorbic acid (DHA), across cell membranes.

One studied demonstrated that this abundance of DHA deactivates the enzyme needed to process glucose, effectively killing the cancer cell by cutting off its food supply.[9]

Not all forms of vitamin C are created equal

In order to achieve these kinds of benefits from vitamin C, though, we must supplement with the right form. Those run-of-the-mill, citrus-flavored pills that fill store shelves won’t cut it.

The studies cited above all implemented either intravenous or liposomal vitamin C. Liposomal supplements used to be few and far between, but now that there’s a number of companies making excellent liposomal vitamin C, getting expensive and unpleasant injections is no longer necessary (unless your doctor recommends it as part of a treatment protocol).

Highest Available Absorption of Vitamin C

PuraTHRIVE’s Liposomalized Vitamin C is absorbed much more efficiently than traditional delivery methods, a huge advance in both efficiency & effectiveness of supplemental nutrients!

Vitamin C just might be one of the most valuable and underestimated natural treatments for serious illness, and you can easily start your own regimen at home. Always consult your doctor before altering any current treatment program, though.
