Does anyone have experience in reducing excess Estradiol?

I am 76 and a men's health blood test shows I have a high level of Estradiol (47 pg/ml) and SHBG (107 nM/liter). I read that this is somewhat common for men as they get older due to the action of aromatase which converts testosterone to estradiol. I also read that the following natural substances will decrease the level of aromatase:
Zinc, resveratrol, red grapes, grape seed extract, green tea and others.
Has anyone been successful at reduction of estradiol and what did you find that worked? Also any comments on SHBG reduction?
