Best Testosterone Supplements

Testosterone is a necessary hormone for both men and women, but it plays a larger role in men due to their higher levels 1. It helps with male sexual health and development, as well as fertility, muscle growth, fat loss, and other health issues 2.

Men's testosterone levels decrease as they get older. An overall drop in testosterone levels in the United States is also causing concern. A role appears to be played by lifestyle habits and health factors 3.
