Sodium Ascorbate is an Alkaline form of Vitamin C

Sodium ascorbate is a form of vitamin C that has been bound to the mineral salt sodium. As vitamin C, the basic properties and health benefits of sodium ascorbate are virtually identical with ascorbic acid, but the mineral salt buffers, thus lowers the acidity of ascorbic acid. The buffered sodium ascorbate may enter the blood stream more slowly than ascorbic acid when taken orally.

Vitamin C Foundation approved vitamin C® products are hypoallergenic fine powders. They are guaranteed to be 100% corn free and GMO free. (i.e., no genetically modified material is used in the manufacturing process.)

The Cathcart's Vitamin C powder from the Vitamin C Foundation is pure L-sodium ascorbate, non-acidic vitamin C that is not made in China - guaranteed

Practically all of the world's vitamin C now on the market in the USA is manufactured in China. While we know of nothing wrong with Chinese Vitamin C, a monopoly is never a good thing for consumers.

Dr Robert Cathcart, III, MD


Sodium Ascorbate is the only form of vitamin C that should be used intravenously, and Sodium Ascorbate is the only form of vitamin C recommended by the late Dr. Robert F. Cathcart, III, MD for intravenous and intramuscular use.
The VItamin C Foundation decided to develop and manufacuture our China-free product after the FDA took action to ban injectible vitamin C from the market. See for detailed information about the FDA action

Clinically, physicians have reported a profound and distinct different in the potency and patient reactions to sodium ascorbate prepared according to Dr. Cathcart's instructions [*] as compared with the inferior commercial buffered ascorbic acid products sold for injections. The Vitamin C Foundation only recommends sodium ascorbate IVCs.

Vitamin C Foundation Approved® Cathcart's Sodium Ascorbate is made from DSM Nutritional Products Quali-C®. The fine powder is non-acidic, hypoallergenic, GMO-free, and 100% corn free. All Vitamin C Foundation Approved® products are certified China-free (Not Made in China).

Dr. Cathcart reported,

.I have not had any trouble with sodium ascorbate solutions. I do not worry about the sterility of this because this solution is very bactericidal. I hear all sorts of weird stories from patients who have gotten their infusions elsewhere. I do not know if it is an acid problem (because ascorbic acid was used rather than sodium ascorbate) or whether some colleagues get carried away with what other things they add to the intravenous solutions.

.I think that there may be, at times minor troubles with commercially prepared solutions because of the following. I understand that the U.S. Pharmacopeia specifies that the solutions be made from ascorbic acid and then buffered with sodium hydroxide or sodium bicarbonate to a pH between 3.5 and 7.0. I worry that 60 grams of ascorbate at a pH of 3.5 is too acid. I know that Fred Klenner (the first physician who used high dose intravenous ascorbate by vein) also made his solutions from sodium ascorbate powder. The pH of this has always turned out to be 7.4..

Intravenous Dosage Guidelines

One gram per kilogram of body weight is a general guideline, which would be about 20 to 25 grams for a 50-pound child and 100 grams for a 220 pound-adult. However, according to vitamin C experts, just giving most adults 50 grams at a time for most conditions works out well.

Rate of infusion can range anywhere from 30 minutes to 3 hours, depending upon comfort of the IV, the amount being administered, and the condition being treated (toxins, more rapid, infections, cancer, etc., less rapid). The more rapid infusions will often be associated with hypoglycemia, which can usually be easily addressed with a little fruit juice or even a candy bar. But it is best if the added glucose/sugar can be avoided.

Dosage is always empirical, as in give more if the clinical response, especially in infections or poisonings, is not adequate. Note: Ascorbic acid should never be used intravenously and can damage veins. The sodium content of sodium ascorbate (113 mg per gram of C) may be of concern to those with hypertension or water retention problems. Interestingly, sodium ascorbate is used in intravenous drips where dozens of grams/day of sodium injected directly into the blood stream doesn't seem to be a problem. Recent research indicates that only highly refined sodium chloride (table salt) may be the real problem for heart patients. Sodium ascorbate is also routinely used as a sugar-free, additive-free, substitute for toothpaste (brush and swallow).

Why Choose Sodium Ascorbate?

Ascorbic acid (hydrogen ascorbate) is highly reactive, and the most powerful and fastest acting form of vitamin C. However, it is too acidic to safely use intravenously. AA must be buffered, or sodium ascorbate can be mixed with water for IV.

The World's Finest Vitamin C (and Cardio-C) are 100% pure L-ascorbic acid (Vitamin C).

Make the Right Choice

While ascorbic acid is more powerful fighting infections and perhaps even heart disease, some people find as the age that acorbic acid becomes harder to take by mouth. Cells in the stomach are used to a highly acidic environment, but sometimes lesions form at the bottom of the esophagus, as tissues leading to the stomach are not acid protected. Both forms of vitamin C, ascorbic acid and sodium ascorbate have similar health benefits. If you experience discomfort while swallowing, and are not fighting the cold or the flu, sodium ascorbate powder can be an excellent choice.

Confused about What is Vitamin C?

The Vitamin C Foundation only markets the real thing. Don't be fooled by high-priced products claiming to be "natural" or "complex" vitamin C. There is no scientific basis what-so-ever for the claim that a "natural vitamin C complex" exists.

DON'T BE FOOLED.
Check the label of high-priced products which claim to be a Natural "Vitamin-C-Complex."

We have noticed that most of these products contain ordinary vitamin C (ascorbic acid), probably made in China.

Our research has shown that almost all so-called "natural" products contain ordinary vitamin C (as ascorbic acid) with a "natural complex" filler added.

A few products offer vitamin C that has been extracted from fruit. The prices for such "natural" products can be an astounding 1000 times greater than the cost of ordinary vitamin C. Vitamin C is the most volatile of all the vitamins, so consumers have no way of knowing how much vitamin C survived the extraction process.

We say: If you want vitamin C from fruit - eat an orange or two, you'll likely get more vitamin C than a "natural complex" product.

Note on so-called 'Natural' Vitamin C

"There is no form of Vitamin C more "natural" than the molecule that virtually all species manufacture in their livers or kidneys - L-ascorbic acid. This molecule in chemical notation is C6H8O6, and your body can't tell the difference between these molecules. " - Owen Fonorow
There are companies that market "natural" C-complexes to hide the fact that their vitamin C is less pure.

Unlike Vitamin E, the only difference between brands of vitamin C are impurities introduced during the manufacturing process.

Study the label of so-called 'natural' products. If the product has more than 200 mg of vitamin C, we will bet it contains regular (manufactured) vitamin C as ascorbic acid. If it contains less, remember you can get the same amount of vitamin C by eating a few oranges.

Note: This product is intended for oral use. Sodium Ascorbate is used for intravenous infusions, intramuscular injections, and is used orally to avoid the acidity of ascorbic acid by sensitive persons.

Vitamin C Foundation Does Not Actually Sell Vitamin C

The Foundation approves and sponsors products, but technically, we do not "sell" vitamin C. Inteligint*Vitamin*C , Inc. (an Illinois corporation) sells our approved products and donates a portion of the proceeds to fund Foundation research and activities.
