> bodybuilding supplements
Nettle Extract is a very popular ingredient in bodybuilding supplements because of its ability to keep testosterone flowing freely through the body. Since testosterone is concentrated in the muscle tissue, Nettle Extract helps to increase the free flowing beneficial testosterone, which means an increase in lean muscle mass.
Nettle extracts are able to boost free testosterone levels. Free testosterone, as opposed to bound testosterone, is active, useable testosterone. This is what provides the benefits typically associated with elevated testosterone levels such as increasing strength and muscle mass. When testosterone binds to sex hormone-binding globulin (SHBG), it changes from free to bound, and becomes useless. Nettle extracts elevate free testosterone levels by binding to sex hormone-binding globulin in place of testosterone, so that a higher percentage of the bodies testosterone is free.

Consequently, nettle may have an anti-inflammatory effect. It may also enhance responses of the immune system.
