Sodium Ascorbate is an Alkaline (non-acidic) 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.

Dr Robert Cathcart, III, MD

Dr. Cathcart was the world's foremost expert on use of intravenous vitamin C, after the pioneer Fredrick Klenner, MD. Dr. Klenners paper often referred to his injections as "ascorbic acid" but Dr. Cathcart checked with his nurses and verified that Dr. Klenner only used the nonacidic sodium ascorbate.

Sodium Ascorbate is the only form of vitamin C that should be used intravenously,

Sodium Ascorbate is the only form of vitamin C recommended by the late Dr. Robert F. Cathcart, III, MD for intravenous and intramuscular use.

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.

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. The Vitamin C Foundation believes that the ascorbic acid form of vitamin C is more potent fighting infections, and may be better against heart disease. However, it is too acidic to safely use intravenously. Ascorbic acid must be buffered for IV, or sodium ascorbate can be mixed with water for IV.

As we age, it can be harder to take pure acorbic acid 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. Linus Pauling himself added sodium bicarbonate (baking soda) to his 9,000 milligrams of ascorbic acid drinks (which turned some of the vitamin C into sodium ascorbate.)

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

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" has any of the effects of vitamin C - the ascorbate ion.
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, where the molecular structure is not precisely known, as there isn't an obvious deficiency disease and the D- form appears to be more effective than the dl-form, 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.
