Why Choose the Ascorbic Acid form of Vitamin C?

Vitamin C comes in various forms. Its most common form, however, is Ascorbic Acid (Hydrogen Ascorbate). Many people use the terms "vitamin C" and "ascorbic acid" interchangeably.
Vitamin C Foundation The Vitamin C Foundation recommends only two forms of vitamin C orally: Ascorbic Acid (Hydrogen Ascorbate) and/or Sodium Ascorbate. Note: Only Sodium Ascorbate is recommended for intravenous infusion.
Ascorbic acid is the most powerful and fastest acting form of vitamin C.

The world's leading clinical vitamin C expert, the late Robert Cathcart,III, M.D., believed that ascorbic acid was twice as powerful as any other form of vitamin C.[]

"I noticed that it was not entirely clear that the dramatic effects are always with ascorbic acid orally and sodium ascorbate intravenously. I have not been able to achieve the ascorbate effect with mineral ascorbates orally.

Mineral ascorbates are fine forms of vitamin C but when you are really sick, the mineral ascorbates are not potent enough to accomplish the ascorbate effect. This is because the mitochondria are failing in their refueling of the free radical scavengers with electrons. The ascorbic acid carries 2 extra electrons per molecule where the mineral ascorbates seem to carry only one (plus per molecule the mineral ascorbates are heavier due to the mineral weighing more than the hydrogen the mineral replaces). There may be other reasons that we do not appreciate additionally." - Robert Cathcart, M.D.

Oral ascorbic acid acts fast, at least in part because ascorbic acid can be absorbed through the stomach wall into the blood stream. The slower acting non-acidic mineral forms of vitamin C have to travel farther into the intestines before they can be absorbed.[]
Vitamin C Foundation Vitamin C is defined as the substance that cures the deficiency disease scurvy. This separates the ascorbates from the ill-defined "natural vitamin C complex." Note that any "natural" complex, minus ascorbic acid, does not and cannot cure scurvy, and therefore, cannot be Vitamin C.
When Other Forms of Vitamin C Are Better
Vitamin C Foundation Not all Vitamin C is acidic. It is also found in various alkaline forms such as the mineral ascorbates: e.g. Sodium Ascorbate, Calcium Ascorbate, Magnesium Ascorbate, Potassium Ascorbate, etc.
Sometimes the bottom of the esophagus becomes sore. This can make it hard to ingest large amounts of vitamin C as ascorbic acid. If you experience discomfort while swallowing ascorbic acid, then sodium ascorbate powder may be a better choice. Both forms of vitamin C, ascorbic acid and sodium ascorbate, have similar health benefits.
Note: You may add some sodium bicarbonate (baking soda) to ascorbic acid in solution. The ensuing reaction turns some of the ascorbic acid into sodium ascorbate.

Why Choose Foundation Approved Vitamin C?

"I have been taking 4 grams of vit C for my asthma for years, but to no real benefit... the doctors kept telling me it should work, but nothing did... until I found your Vit C, that is... it has turned my life completely around (for the better)! I'm experiencing good health for the first time and am recommending it to anyone who will listen... don't change a thing... it's wonderful, and worth the expense!" - Nancy
"Owen,
Thank you for the tip on Trader Joe's vitamin C (as a low cost alternative.) I already use it, but YOUR vitamin C is THE best product I have found. I wasn't able to walk a few years ago because my circulatory system was shutting down. And it was your product that 'saved' me! Thank you again!!

How Much Should I Take?

Strangely, Vitamin C is not a "vitamin" for most animals. As a rule, most species make ascorbate in their livers (or kidneys) all day long (24/7) in amounts (adjusted for body weight) between 3,000 and 13,000 milligrams.

There are exceptions. A few animals must obtain some vitamin C in their diets every day because they are unable to make it. These are the guinea pig, fruit bat, several species of parrot and several high order primates, including humans.

After years of study, vitamin C expert and Nobel prize winning scientist Linus Pauling supplemented 18,000 mg of ascorbic acid.

Pauling's reasoning was that this amount matched blood levels in animals that make their own vitamin C. He adjusted for his body weight and accounted for loss in the gut during digestion.

His daily amount was divided into two equal dosages of 9,000 mg, to which he added a teaspoon of sodium bicarbonate (baking soda).

In ordinary health:

The Vitamin C Foundation recommends 3000 milligrams divided into 3 equal 1 gram doses daily. (Less for children under 5 years old, adjusted for body weight.)

For optimal health and longevity:

Linus Pauling recommended 6,000 mg to 18,000 mg daily in his book "How To Live Longer And Feel Better" (1986). [1]

During times of extreme illness:

Dr. Robert Cathcart recommended using bowel tolerance to help determine the correct dosage. These dosages can exceed more than 200,000 milligrams. See: Titrating Vitamin C to Bowel Tolerance

Jaffe C-Cleanse/Calibration:

We are all individuals with varying requirements for vitamin C. The Russell Jaffe Vitamin C Calibration (sometimes called Cleanse) can be used to estimate the daily need.
Vitamin C Foundation The Jaffe technique uses the highest one-time amount that can be consumed without diarrhea -- usually 3 to 10 grams. This amount is taken every 15 minutes until there is a watery "discharge," usually around the two hour point.
"Based on ascorbate calibration, it is evident from Figure 3 that 80% of people require at least 10 g of ascorbate (vitamin C) daily for optimum physiological function, and this amount can be as high as 130g/day." - Russell Jaffe, MD, PhD
Figure 3:
75% of the amount taken during the calibration is the recommended daily amount.

Powder versus Capsules

Pure vitamin C powder is the only form we approve.

For those that find ascorbic acid powder hard to swallow, it is easy and inexpensive to make your own capsules. Check out your local health food store for generic capsules and the do-it-yourself capsule making kits.

"As they researched their book ASCORBATE, Hickey and Roberts began to wonder if Pauling's offense had been to discuss openly the properties of a substance that threatens the profitability of medicine. If the claims for vitamin C are correct, it might replace many lucrative and expensive medications."
