People often turn to self-therapy because they have not been helped by conventional medicine, or because they simply don't trust it. He's got a point and, not surprisingly, many people want to take their health into their own hands. I certainly do. Most animals need vitamins and minerals in relatively small amounts ranging from a few mcg to 50 mg. There's good reason to believe vitamin C is different and that it's more than just another vitamin.
Most animals manufacture their own vitamin C - and lots of it at that.
On average, a 150-pound animal produces 4,000 to 13,000 mg. of vitamin C daily. Only a handful of animals, including human beings, do not. Researchers believe that a genetic accident occurred 25 millions years ago in one of our evolutionary ancestors, eliminating our ability to produce this vitamin. In the 1960s, Irwin Stone, D.Sc., theorized that people still have the need for large doses of vitamin C, even though they don't produce it. Gorillas, among our nearest biological relatives, eat about 4,000 mg. of vitamin C daily in the wild.
