Supplements... Yes or No?

NEA Today, Jan 2008

Taking a daily multivitamin can be wise, but unless you're pregnant, elderly, or have other distinct supplemental needs, Christina Economos cautions against taking much else. Vitamins and supplements are not FDA-regulated so quality isn't assured, says Economos, associate director of the John Hancock Center for Physical Activity and Nutrition at Tufts University and a research scientist at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts.

"There can be interactions with foods and medications. If you're taking multiple things, there can be competition for absorption." Some substances can also accumulate in the body and/or be dangerous at high levels. The best way to ensure you're getting adequate nutrients is to "ask your doctor for a referral to a registered dietician who can analyze your diet and identify where you may be lacking. Nutrition can be complex, so investing in an appointment can be worth it."
