I tried Japanese supplements but they did not work for me. I am happy to find the best one for my menopause. When I do not feel well, I take one and will feel better and comfortable. Life of the mother A and soy isoflavone to me there is no effect, I was looking for a herbal supplicant friendly to the body. Became so easy was use found in the import supplicant site of Japan, buy here. I am only one capsule drinking when in poor physical condition. It has been formulated with other herbs, but excessive intake of black cohosh does not have the usual because it is worry.
