Natural testosterone supplements, also known as testosterone boosters, contain potent herbal extracts that can prompt the body to produce more testosterone. Testosterone boosters also contain ingredients to block the conversion of testosterone into DHT and estrogen. Other ingredients help by unbinding testosterone that is bound, and therefore unavailable for use by the androgen receptors of muscle tissues.
