No Scientific Evidence Supporting Health Claims Of Vitamin Industry

August 18, 2015: 12:00 AM EST
The author of a book on America’s obsession with vitamins and other supplements says any benefit derived from popping the pills is probably a placebo effect. Most foods we eat – even donuts, cakes, and cookies, all made with enriched flour – provide all the vitamins we need. The only time supplementary vitamins should be taken is when there is evidence of a deficiency, such as vitamin C to cure or prevent scurvy. The fact is, there is almost no scientific evidence supporting the supplement industry’s health claims for its products. And thanks to the federal government, they don’t have to provide such evidence.
