PHYTOPIN is a natural beta sitosterol extracted from French maritime pine. Beta Sitosterol can inhibit the enzyme 5 alpha reductase. 5 alpha reductase converts testosterone to dihydrotestosterone (DHT). DHT attacks hair follicles (both in men and women) and prostate (in men). DHT is the culprit responsible for male/female pattern hair loss (androgenic alopecia) and benign prostate hyperplasia (BPH) in men. A couple of clinical studies have proven that PHYTOPIN was able to inhibit 5 alpha reductase, lower DHT level and alleviate symptoms of BPH.
