Dietary Supplements: Too Much of a Good Thing? | LiveScience

Get your nutrients from food, not pills !

Outside of this dietary supplement report, the NIH and other health organizations have recommended iron supplements for women of childbearing age, because of iron lost in menstrual blood. But men, in general, don't need iron pills. (Earlier I confessed to taking a multivitamin; this contains no iron, and no vitamin or mineral exceeds the U.S. RDA.)

The long-standing advice has been to get your nutrients from food, not pills.

Would you willingly down a concoction of pyridoxine, pantothenic acid, ascorbic acid, and alpha-tocopherol? How about 2-Me-3-polyisoprenyl-1,4-naphthoquinone? Understanding that vitamins B5, B6, C, E and K are chemicals and not just alphabet soup might caution us to consume these in moderation.
