I had spotting at times before I was menopausal and never attributed it to the Revival and have been using it since May or June of 1998. On Synthroid, simply take your soy products at a different time of the day and you won't have any problems. Thank you very much. Sally, Revival doesn't have any estrogenic effect in men. No studies have ever shown any detrimental effects.
Japanese men have the longest lifespan in the world.
New studies show that soy protects men's hearts and may protect the prostate and colon. No it is not, because soy protein protects the heart, without stimulating the breast and endometrial tissues. Prescription estrogen protects the heart, but has been consistently shown to overstimulate the breast and endometrial tissues, and can have many adverse side-effects. You should consult your own doctor about adding soy protein to your diet if you are taking prescription estrogens. We have new studies with Revival showing anti-inflammatory properties to breast tissues that will be released soon.
