"Naturally, drug ads don't mention that adequate doses of vitamin E (400-1200 IU/day) will slow blood clot formation and along with adequate doses of vitamin C (3000-6000 milligrams/day) and magnesium (300-600 mg/d) will help to keep blood vessels strong and elastic, thereby reducing the risk of developing diabetes, arterial plaque formation, heart attack, and stroke.[1-7] Much higher-than-RDA doses of vitamin supplements, including vitamin K, are considered helpful for long-term health.[7] But until the drug industry develops replacements for vitamins C, E, and K and essential minerals that are deficient in the modern diet, I expect that drug profits will continue to be promoted by misleading ads."
