As baby boomers are heading for their sixties, anti-aging medicine is becoming popular in Japan -- though it may be some time before we catch up with the United States, where more is now reportedly spent on supplements than prescribed medicines.
However, although some of these supplements have some effect, for most there is no anti-aging evidence.
For example, Vitamin C is a proven anti-oxidant, and is hence beneficial in addressing an important cause of aging of cells and organs like the skin. On the other hand, Vitamin E was long thought to have the same effect, but a recent U.S. study failed to demonstrate its anti-oxidant effect on the heart.
