DR. RODGERS: Many adults take dietary supplements. How much do you really know about them?

Hi, I'm Dr. Griffin Rodgers, director of the National Institute of Diabetes and Digestive and Kidney Diseases at NIH.

My colleague, Dr. Josie Briggs, director of the National Center for Complementary and Integrative Health at NIH, explains:

DR. BRIGGS: Dietary supplements include vitamins, minerals like calcium and iron, herbals, and products such as probiotics and fish oils. They can come in a pill, powder, drink, and even an energy bar.

Most doctors recommend a multivitamin with folic acid for pregnant women to help prevent certain birth defects.

It is also important to remember dietary supplements can't replace a healthy diet, and some contain ingredients that can interfere with the action of medications.

Always talk to your doctor about any dietary supplements you're taking or thinking about taking.
