A recent study1 reviewed claims made for fifty popular “testosterone boosting” supplements. The authors found the claims made for the products to be unproven and mostly false.
The study found the following claims made for the supplements:
|Make men “feel stronger”||48%|
|Build body mass||62%|
The study found that only 12% of the products contained any ingredients that had been linked to improved testosterone in human trails, and almost half (48%) contained ingredients that have been linked to negative side effects.
Many of the supplements contained levels of vitamins and minerals far in excess of recommended daily allowances.
Note that over-the-counter supplements should not be confused with FDA-approved testosterone replacement therapies.
