Official dietary recommendations for daily Vitamin C intake range from 75 mg to 110 mg, but these amounts represent only a tiny fraction of the daily Vitamin C production in most animals. The Recommended Daily Allowance (RDA) of Vitamin C in the United States is 90 mg for men and 75 mg for women. The Recommended Daily Intake of Vitamin C in Germany, Switzerland, Austria, and Japan is 100 mg and in France it is 110 mg.1 This amount can be easily found in fresh fruits and vegetables. However, the Vitamin C intake in the typical American diet is repeatedly found to be low.
Biochemical Individuality Versus Population Averages
Elizabeth Sommer, a dietitian, remarked, “No method is available even to thee researchers, let alone the concerned consumer to assess the optimal Vitamin C requirements.”2 Each individual has his or her own needs which can change with various life circumstances. The body selectively absorbs nutrients from whole food complexes, using all that it needs and excreting any excess.
Biochemical individuality is a concept from the work of Roger J. Williams, at the University of Texas, which indicated that individuals vary over a considerable range in their need for and use of metabolites and a value based on a so-called average may be far off the mark.3
Humans have a genetic absence of the liver enzyme L-gulonolactone oxidase, which is responsible for the conversion of sugar (glucose) into ascorbic acid. This condition is called hypoascorbemia.4 Hypoascorbemia in humans can only be controlled with the daily intake of an adequate amount of Vitamin C complex (contains ascorbic acid). Most animals produce their own ascorbic acid in large quantities (thousands of milligrams per day).
An average adult male weighs 154 pounds, which is the size of a goat. Goats have some similarities to humans. For example, human breast milk is very similar to goat milk. A goat synthesizes about 13,000 mg of ascorbic acid a day and requires an intake of 2000-4000 mg per day Vitamin C complex,4,5 which it obtains from its extensive consumption of grasses and other plants.
The above is the reason why most doctors in alternative medicine recommend 2000-4000 mg of ascorbic acid daily.
There is no storage depot of Vitamin C in the human body, thus a continuous supply of Vitamin C complex is required to replenish losses. The body selectively absorbs nutrients from whole food complexes, using all that it needs and excreting any excess. One of the most outstanding attributes of the Vitamin C complex is its lack of toxicity even when given in large doses over long periods of time.
Vitamin C complex is critically important to every cell of the human body and constant adequate supply is a necessity.
