Should RDA of Vitamin C Be Increased?

vitamin c inflammation

Are you treating your disease, or symptoms of your disease?

Should recommended dietary allowance (RDA) of vitamin C be increased? “An excellent diet with the recommended five to nine daily servings of fruits and raw or steam-cooked vegetables, together with a six-ounce glass of orange juice, could provide 200 milligrams of vitamin C a day. But most Americans and people around the world do not have an excellent diet.” Is 200 mg enough? What if you have an inflammatory condition, such as high blood pressure, diabetes, or heart disease? Does this increase your need for anti-inflammatory vitamin C?

Educate yourself. Are you treating symptoms or underlying causes of disease? Could your medication be contributing to the imbalance in your body that is causing inflammation? Supplementing with vitamin C powder may be just what you need to improve your condition and increase the duration and quality of your life. Check out this article published by News Medical Life Sciences & Medicine.

Healthier Levels of Vitamin C Can Reduce Inflammatory Conditions

The recommended dietary allowance, or RDA, of vitamin C is less than half what it should be, scientists argue in a recent report, because medical experts insist on evaluating this natural, but critical nutrient in the same way they do pharmaceutical drugs and reach faulty conclusions as a result.

The researchers, in Critical Reviews in Food Science and Nutrition, say there’s compelling evidence that the RDA of vitamin C should be raised to 200 milligrams per day for adults, up from its current levels in the United States of 75 milligrams for women and 90 for men.

Rather than just prevent the vitamin C deficiency disease of scurvy, they say, it’s appropriate to seek optimum levels that will saturate cells and tissues, pose no risk, and may have significant effects on public health at almost no expense – about a penny a day if taken as a dietary supplement.

“It’s time to bring some common sense to this issue, look at the totality of the scientific evidence, and go beyond some clinical trials that are inherently flawed,” said Balz Frei, professor and director of the Linus Pauling Institute at Oregon State University, and one of the world’s leading experts on the role of vitamin C in optimum health.

“Significant numbers of people in the U.S. and around the world are deficient in vitamin C, and there’s growing evidence that more of this vitamin could help prevent chronic disease,” Frei said. “The way clinical researchers study micronutrients right now, with the same type of so-called ‘phase three randomized placebo-controlled trials’ used to test pharmaceutical drugs, almost ensures they will find no beneficial effect. We need to get past that.”

Unlike testing the safety or function of a prescription drug, the researchers said, such trials are ill suited to demonstrate the disease prevention capabilities of substances that are already present in the human body and required for normal metabolism. Some benefits of micronutrients in lowering chronic disease risk also show up only after many years or even decades of optimal consumption of vitamin C – a factor often not captured in shorter-term clinical studies.

A wider body of metabolic, pharmacokinetic, laboratory and demographic studies suggests just the opposite, that higher levels of vitamin C could help reduce the chronic diseases that today kill most people in the developed world – heart disease, stroke, cancer, and the underlying issues that lead to them, such as high blood pressure, chronic inflammation, poor immune response and atherosclerosis.

“We believe solid research shows the RDA should be increased,” Frei said. “And the benefit-to-risk ratio is very high. A 200 milligram intake of vitamin C on a daily basis poses absolutely no risk, but there is strong evidence it would provide multiple, substantial health benefits.”

An excellent diet with the recommended five to nine daily servings of fruits and raw or steam-cooked vegetables, together with a six-ounce glass of orange juice, could provide 200 milligrams of vitamin C a day. But most Americans and people around the world do not have an excellent diet.

Even at the current low RDAs, various studies in the U.S. and Canada have found that about a quarter to a third of people are marginally deficient in vitamin C, and up to 20 percent in some populations are severely deficient – including college students, who often have less-than-perfect diets. Smokers and older adults are also at significant risk.

Even marginal deficiency can lead to malaise, fatigue, and lethargy, researchers note. Healthier levels of vitamin C can enhance immune function, reduce inflammatory conditions such as atherosclerosis, and significantly lower blood pressure.

•A recent analysis of 29 human studies concluded that daily supplements of 500 milligrams of vitamin C significantly reduced blood pressure, both systolic and diastolic. High blood pressure is a major risk factor for heart disease and stroke, and directly attributes to an estimated 400,000 deaths annually in the U.S.

•A study in Europe of almost 20,000 men and women found that mortality from cardiovascular disease was 60 percent lower when comparing the blood plasma concentration of vitamin C in the highest 20 percent of people to the lowest 20 percent.

•Another research effort found that men with the lowest serum vitamin C levels had a 62 percent higher risk of cancer-related death after a 12-16 year period, compared to those with the highest vitamin C levels.

Laboratory studies with animals – which may be more accurate than human studies because they can be done in controlled conditions and with animals of identical genetic makeup – can document reasons that could explain all of these findings, Frei said.

Critics have suggested that some of these differences are simply due to better overall diet, not vitamin C levels, but the scientists noted in this report that some health benefits correlate even more strongly to vitamin C plasma levels than fruit and vegetable consumption.

The Clinical Impact of Vitamin C: My Personal Experiences as a Physician

Vitamin C Research

Actual cases of flu, mono, lyme disease and more treated with intravenous vitamin C.

Commentary by Thomas E. Levy, MD, JD

(OMNS Sept 3, 2014) My ongoing relationship with vitamin C now spans a full 20 years, when I first met Dr. Hal Huggins, a pioneering dentist who opened my eyes to a wide array of clinical approaches to different diseases with hitherto unheard-of clinical results at his clinic in Colorado Springs. I can honestly say that my first visit to his clinic began the most meaningful part of my medical education. Nothing has been the same since. My office where I practiced adult cardiology ended up being shuttered shortly after that first visit. And I have never looked back.

How to Maximize Your Vitamin C Benefits

Friday, February 10th, 2012

Learning how to correctly take your vitamin C can help you to increase the benefits that you get from it. Vitamin C will give you protection from scurvy at minimal levels, but won’t necessarily provide you with symptom relief or protection from major diseases unless it is taken at a high enough level. It’s hard to say what the correct “daily requirement” of vitamin C is because everyone has a different level of stress or disease in their body. Therefore, learning how to find the right dosage for your condition and your body can be greatly beneficial.

In general, bowel tolerance of ascorbic acid is proportionate to the toxicity of your disease. In other words, you won’t eliminate excess vitamin C until it’s out of things to correct in your body. Therefore, a daily dose when you’re healthy can range anywhere from 1 to 20 grams per day, depending on the condition and need of your body. One study showed that people with influenza (the flu) or mononucleosis (mono), could take up to 200 grams of vitamin C daily without stomach discomfort or diarrhea. In fact, for severe illnesses such as these, marked improvement was not shown until the dosage of ascorbic acid reached near the bowel tolerance level. The reason that you may not feel better when taking smaller doses of vitamin C is that it is quickly destroyed by injured tissues, disease, and stress. Think of it as trying to wash mud off of your arm with only a few drops of water. It may get smeared around, but the mud is still there. Only with larger and larger amounts of water would you be able to clean off the mud.

Vitamin C works by scavenging free radicals produced by stress, infection, inflammation, germs, bacteria, illness and disease. Not only do diseases and injuries cause damaging free radicals to form, they also lead to the formation of other diseases. Almost every disease is caused by and/or produces free radicals. Infection, heart disease, cancer, burns, trauma, aging, allergies, and autoimmune diseases are all included.

Taking vitamin C daily can vastly reduce your chances of developing a giant list of health conditions. Vitamin C is very sensitive to stress and is generally the first vitamin to be depleted by it. Without enough vitamin C in your system daily, stress can take its toll on your immune system very quickly. Vitamin C is known to bring balance to an overactive or weakened immune system. It does the same for your stress response, helping to control anxiety, overproduction of cortisol (stress hormone), and inflammation.

Many people don’t realize that vitamin C is required by our bodies daily to maintain cartilage, bones and teeth. It is also necessary for producing collagen, absorbing iron, and controlling cholesterol levels. Our bodies go from growing and developing to breaking down and aging. Our cells and connective tissues, even bone, are always regenerating. If enough vitamin C isn’t available for the production of collagen and elastin, our bodies will improvise by using hard, inflexible cholesterol plaques to repair tiny tears and injuries. This is how arteries harden, joints become more prone to damage, and wrinkles form.

Talk with your doctor about supplementing with the best vitamin C, sodium ascorbate vitamin C powder. This highly absorbable, non-acidic form of vitamin C is the most economical and easiest way to get your perfect daily dose of vitamin C.
