Aging & Dietary Supplements (cont.)
Are These Supplements Safe?
Are you thinking about using dietary supplements? Remember that these "over-the-counter" substances are not like the penicillin or blood pressure medicine your doctor might prescribe for you. The U.S. Food and Drug Administration (FDA) has to check prescription drugs to make sure they are safe and do what they promise before they are sold. The same is true for "over-the-counter drugs" like cold and pain medicines. It is not the FDA's job to check dietary supplements in the same way. That means they are not reviewed by the FDA before being sold, but it is the FDA's job to take action against unsafe products on the market. Only if enough people report problems with a dietary supplement, can the FDA study these possible problems and take action.
Besides the FDA, many federal government agencies and private groups are interested in dietary supplements. The National Institutes of Health (NIH) is the federal focal point for medical research in the United States. NIH supports research studies looking at the safety and helpfulness of some of the ingredients found in many supplements.
Business and consumer groups are also interested in dietary supplements. So are private professional groups such as the National Academy of Sciences (NAS). The NAS develops guidelines saying how much of each vitamin and mineral people need.
What About Vitamins and Minerals?
Vitamins and minerals are nutrients found naturally in food. We need them to stay healthy. The benefits and side effects of many vitamins and minerals have been studied. The best way to get vitamins and minerals is through the food you eat, not any supplements you might take. Try to eat the number of servings of food recommended by the U.S. Department of Agriculture's Food Guide Pyramid each day (see chart). Pick foods that are lower in fat and added sugars. If you can't eat enough, then ask your doctor if you should be taking a multivitamin and mineral supplement. And remember:
How much should you take?
The NAS has developed recommendations for vitamins and minerals. Check the label on your supplement bottle. It shows the level of vitamins and minerals in a serving compared with the suggested daily intake.
