Feature Summary: EstroVantage EM provides a comprehensive formula of plant-based compounds that improve the metabolism of estrogen and its metabolites. Cruciferous vegetables contain a variety of glucosinolates, which some studies have associated with a reduction in cancer incidence when consumed in greater amounts, most likely by causing a shift in metabolism to less carcinogenic estrogen metabolites.1,2 EstroVantage EM contains indole-3-carbinol (I3C) and its metabolite 3,3’-diindolylmethane (DIM), as well as sulforaphane from broccoli powder, all of which have been linked to lower rates of neoplastic changes and a more favourable estrogen profile.3-6 Not only do these glucosinolates improve estrogen metabolism, they also reduce inflammation by targeting key signalling molecules, such as Nrf2 and NF-κB.7,8
EstroVantage EM also includes other potent plant compounds that reduce inflammation and block carcinogenic pathways. Silymarin, a milk thistle extract, down-regulates gene products involved in the proliferation of tumour cells, along with their invasion, angiogenesis, and metastasis. In addition, it enhances glucuronidation and maintains glutathione levels.9-11 This unique combination provides green tea polyphenols, lycopene (tomato extract), turmeric and rosemary extracts, as well as calcium D-glucarate, all of which have been shown to favourably shift estrogen metabolism and reduce carcinogenic risk.12-14 Most recently, a randomized, double-blind, placebo-controlled crossover study demonstrated that taking this formula led to markedly higher urinary levels of the protective 2-OHE1 estrogen metabolite and lower levels of the more dangerous 16α-OHE1 estrogen metabolite in premenopausal women.Most recently, a randomized, double-blind, placebo-controlled crossover study demonstrated that taking this formula led to markedly higher urinary levels of the protective 2-OHE1 estrogen metabolite and lower levels of the more dangerous 16α-OHE1 estrogen metabolite in premenopausal women.15
