dietary supplement savvy

by Carol Plotkin, MS, RD

Ever wonder if you should take a supplement to prevent arthritis pain? Or to stop a cold? One in three Americans takes a dietary supplement hoping to prevent illness. We believe the vitamins, minerals, and other molecules in foods can keep us well. But when we take the nutrients out of food and put them in a pill, we don’t always see the health benefits we expect. In our bodies, these molecules act along with other nutrients in ways we don’t completely comprehend. This action cannot always be mimicked by nutrients in a pill. However, supplements can add some value to one’s health, and by following a few rules for safe supplementation you won’t go wrong.

1. Eat a balanced diet. If your diet’s bad, a supplement won’t save you. See www.MyPyramid.gov for more information.

2. Look at the nutritional quality of your diet and supplement where indicated: For example, research is showing that vitamin D is very important for preventing osteoporosis. It has been suggested that vitamin D intake should be 800-1000 IU daily. Add up what you get from your diet and make up the difference with supplements.

3. Be aware of the maximum dosage and do not exceed it. For example, in small doses zinc can enhance the immune system, but in excess it can actually hurt immune function. Keep this in mind if you are taking zinc for a cold while taking a multivitamin and mineral supplement. The safe upper limit for zinc is 40 mg daily.

4. Always inform your doctor about your dietary supplements. Some supplements may interact with medications. This list includes commonly taken drugs, so it’s always a good idea to check.
