Testosterone Supplement Claims Not Always Backed by Medical Research

Testosterone Supplement Claims Not Always Backed by Medical Research“Testosterone boosting” (sometimes called “T boosting”) supplements may claim to improve a man’s testosterone levels along with his libido, muscle mass, and energy. But there is little scientific research available to substantiate such claims, according to a recent study in the World Journal of Men’s Health.

Men’s testosterone levels gradually decline as they get older. For some men, this drop leads to fatigue, moodiness, less interest in sex, and reduced muscle mass. Testosterone replacement therapy (TRT) is sometimes prescribed to alleviate these symptoms.

However, some men decide to try dietary supplements instead, feeling that it is a more “natural” approach. But supplements aren’t regulated by the U.S. Food and Drug Administration (FDA), and their manufacturers aren’t supposed to make claims that their products can treat medical conditions. Yet some still do.

“Many supplements on the market merely contain vitamins and minerals, but don’t do anything to improve testosterone,” study co-author Mary K. Samplaski said in a University of Southern California report. “Often, people can be vulnerable to the marketing component of these products, making it difficult to tease out what is myth and what is reality.”

Researchers used the search terms “testosterone booster” and “testosterone supplement” to conduct a Google search of these supplements. They studied the ingredients and manufacturers’ claims for 50 products.
