Maintaining normal testosterone levels is one of the most important steps men can take to regain their health and improve their performance. By maintaining healthy testosterone levels as they age, men can support their overall cardiovascular health as well as sexual health. Super MiraForte from Life Extension® features high potencies of chrysin and nettle root extract. These ingredients reduce the aromatization (conversion) of testosterone to estrogen and enhance free testosterone levels. Bioperine® is included to facilitate the absorption of chrysin (a flavonoid) into the bloodstream. Muira puama is also included in this formula to further enhance sexual function and performance.
