Double dose … – research indicates recommended daily allowance for vitamin C should be doubled or tripled – Brief Article
Double dose … The recommended daily allowance for vitamin C should be doubled or even tripled, say government researchers, because of increasing evidence over the last two decades of the vitamin’s cancer-fighting ability when consumed in fruits and vegetables. The National Institutes of Health says the allowance should be 100 to 200 milligrams instead of the current 60 milligrams established by the National Academy of Sciences in 1980. But researchers are not sure if benefits come from the vitamins themselves or from the vitamins plus other components of the food containing the vitamins. And they add that there is such a thing as too much vitamin C: 200 milligrams is the maximum the body can absorb. Larger amounts can increase the risk of kidney stones.
