High-risk dietary supplements are those that may present serious health risks. Many have been found to contain undeclared drug ingredients, steroids, steroid-like ingredients, and/or stimulants, which can have negative and dangerous side effects. Products most commonly “tainted” in this way are those marketed for bodybuilding, performance enhancement, weight loss, sexual enhancement, and diabetes. Such products may also result in a positive drug test. For more information, see FDA’s "Beware of Fradulent Dietary Supplements” For more information about urinalysis and drug testing, read OPSS’s “Dietary supplements and drug testing.”

In addition, you can visit the OPSS High-Risk Supplement List for information about certain dietary supplements that may pose a health or sport anti-doping risk.
