About Estrogen Blocker

Estrogen Blockers provide options for those that want to reduce their estrogen burden. Estrogen is not actually one single hormone, like progesterone, but is actually a class of hormones, which are estriol, estradiol, and estrone, plus a the metabolites that are created once the liver processes these. Increasing our levels of more beneficial estrogens, and decreasing levels of the more potent ones, can be helpful for supporting the body in a number of different ways.


Furthermore, many bodybuilders use natural estrogen blockers to keep their estrogen signals to a minimum, which is helpful with a high aromatisation of testosterone. This simply means that testosterone is being converted to estrogen via an enzyme called aromatase. Both women and men synthesize an enzyme called aromatase, which is responsible for the conversion of testosterone to estrogen. As testosterone and estrogen are synthesized in both women and men, they are useful for both genders. 


Some of the conditions classed as estrogen dominant for women are endometriosis, breast lumps and some forms of premenstrual tension, as well as heavy monthlies. Men typically tend to use estrogen blockers when they are trying to minimise testosterone to estrogen conversion, in order to maintain a higher testosterone level to support faster recovery from exercises such as weight lifting. Testosterone, after all, is a major stimulator of muscle protein synthesis, which is a major anabolic process in the body. 


Hormonal biochemistry is, however, not as simple as reducing aromatase activity. There are also compounds that block the estrogen and androgen receptors and others that modulate the types of estrogen metabolites that we synthesize. For instance, the net effect of more 2-alpha hydroxyestrone and less 16-alpha hydroxyestrone is less estrogen burden. A journal called Cancer Epidemiology, Biomarkers and Prevention in 2000 demonstrated that broccoli can increase this ratio, positively impacting the estrogen profile. Broccoli contains a compound called indole-3-carbinol, which has been researched for decades now.


This natural phytochemical converts to diindolylmethane, which then beneficially influences the estrogen profile. Broccoli is not the only source, however, as it is found in all cruciferous vegetables, such as brussel sprouts, cabbage and cauliflower. It is also believed that during benign prostatic hypertrophy (BPH), the estrogen burden of the body may be in excess, making the "estrogen blocker" approach also quite helpful. 


Whether it be to recover faster from exercise, assist in the management of BPH or endometriosis, take your time browsing this section to see which product is most suitable for you.
