The other class of booster taken into consideration is one that uses saw palmetto. Saw Palmetto extract is linked to testosterone levels. Scientists have discovered that Saw Palmetto slows down 5-alpha reductase, which is an enzyme that converts testosterone into DHT (Dihydrotestosterone). Saw Palmetto is widely used in men’s supplements, particularly concerning prostate health. In addition to benefits to the prostate, reducing DHT is thought to prevent – or at least slow – male pattern baldness.
