Why dietary supplements for weight loss may be ineffective

There are many weight-loss supplements on the market that claim quick results, but these may be ineffective or lead to harmful side effects.

What are dietary supplements?

Dietary supplements for weight loss may come in the form of pills, liquids, or powders and many contain dozens of ingredients, like herbs, plant fibers, or caffeine.

Why weight-loss supplements may be ineffective or harmful

The evidence around weight-loss supplements and ingredients contained in these supplements varies a lot.

How to recognize potentially tainted products

The FDA has identified some weight-loss supplements that have been tainted with drug ingredients. While some of these have been removed from the market, some tainted products continue to be sold.

How can prescription medication help with weight-loss?

Unlike dietary supplements, prescription medications are FDA approved for both short-term or long-term use.

Talk to your doctor if you’re considering supplements

Your doctor or health care provider can help you weigh the risk and benefits of using certain weight-loss supplements. It’s also important to let them know about health conditions or medications you’re on, as the ingredients in supplements can interact with medications and cause unwanted side effects.
