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 Fraudulent Dietary Supplements.” For more information about urinalysis and drug testing, read OPSS’s “Dietary supplements and drug testing.”
