Testosterone boosters are a class of herbal supplements aimed at naturally increasing your testosterone levels. Usually, they contain micronutrients that men are commonly deficient in, such as zinc, and which have been connected in research to healthy testosterone levels. They also may contain adaptogens, which are a class of supplement that are thought to help the body adapt to stress, or ingredients that have been connected to improved sleep.

Testosterone boosters can work by increasing testosterone within a normal range, or by providing indirect hormone support. Either way, in the end, these supplements are meant to give all the benefits a healthy testosterone level can provide: faster recovery from exercise, bigger and stronger muscles, and increased libido, to name a few.[2] **https://www.bodybuilding.com/content/do-testosterone-boosters-really-work.html#what-do-testosterone-boosters-do
