Popular Supplements for Athletes

There are several products on the market that claim to make you better, faster, and stronger. Because you care about your body and performance, these products may be very appealing.

Even though supplements are regulated by the Food and Drug Administration (FDA), manufacturers are not required to prove that a supplement is safe, or that it does what it claims to do, before putting it on the shelf.

Take caution if the product claims that it is a quick and easy solution, it works for everyone, or it has a "secret formula." Do your research and consult a registered sports dietitian. Be wary when considering dietary supplements. See the table below for information on current popular supplements.
