Same story, new data, and a message that needs repeating: Over-the-counter supplements — sold as safe alternatives to prescription drugs for weight loss, muscle building, and sexual enhancement — may be risky and not beneficial to your health. Indeed, many of them are adulterated with strong prescription drugs.
As the Washington Post reported of a newly published study:
Researchers found unapproved and sometimes dangerous drugs in 746 dietary supplements, almost all of them marketed for sexual enhancement, weight loss or muscle growth … [A scientific] review of a Food and Drug Administration database of contaminated supplements for the years 2007 to 2016 most commonly turned up sildenafil — the drug sold as Viagra — and other erectile dysfunction drugs in sex enhancement products; sibutramine and the laxative phenolphthalein, both banned by the FDA, in weight-loss supplements; and steroids or their analogues in muscle-building products. About 80 percent of the supplements were contaminated by one pharmaceutical that should not have been in the product. Twenty percent contained at least two such drugs, and two of the supplements contained six unapproved drugs. One product contained a drug that raises blood pressure and another drug that lowers it. Despite these contaminants, fewer than half the products were recalled.
