NATURAL PROGESTERONE- (PC is another strong 5 alpha reductase inhibitor), ALSO AGAINST BPH AND PROSTATE CANCER.
♦ PROGESTERONE is a natural inhibitor of 5-alpha reductase - an enzyme needed to convert TESTOSTERONE to growth- stimulating di-hydroTESTOSTERONE (DHT). Not only is DHT implicated in BPH and prostate cancer, but this conversion also reduces TESTOSTERONE, thus lowering the TESTOSTERONE to estrogen ratio and creating an estrogen dominance situation.
