Vitamin C and risk of coronary heart disease in women
Vitamin C is one of those supplements that has had an incredibly amount of research behind it. Although its benefits in cardiovascular disease has not been fully established (with several recent studies showing no benefit), this article does demonstrate a benefit. Keep in mind that I usually recommend 2 grams/day of Vitamin C as a base, so many of these studies are done at dosages that I consider very low.
