Take the Quiz: Do You Need to Supplement? - Quality for Life

Elizabeth Somer, M.A., R.D.




You probably don’t eat as well as you think. While most people say they eat pretty well, most are mistaken. (1-3,7)  A survey conducted by the National Cancer Institute and the U.S. Department of Agriculture (USDA) found that 99 out of every 100 of us don’t meet even minimum standards of a good diet. (4)

Nutrition through diet or through supplements is not an either-or issue. You don’t always get optimal amounts of all the essential nutrients from food, just as pills don’t contain everything food has to offer. That’s why they are called “supplements” not “substitutes.” A good supplement plan can fill in the gaps when you don’t eat perfectly. (43) Of course, you can’t live on doughnuts and fast food, then take a supplement and think you’re doing fine.  You need to eat well AND supplement responsibly. (5)

For quality sake, choose major brands or a product with the United States Pharmacopoeia (USP) quality seal that guarantees high standards. (6)  Avoid the unsubstantiated claims of  "therapeutic," "high-potency," “women’s formulas” or "stress-formulated" supplements. Those terms are not guaranteed to deliver a better-formulated product and typically cost more.
