For centuries on end women in Thailand have used Pueraria mirifica to help their body make a milder transition into menopause. As a member of the legume family, Pueraria mirifica contains many of the same phytoestrogens found in soy while also containing unique phytoestrogens which are found in no other plant. These phytoestrogens have the highest bioactivity known which exceeds about 3000 times the activity of soy isoflavones and 100 times the activity of the red clover. Our vegetable capsules contain the patented formula Puresterol® - an extract of Pueraria mirifica – and are enriched with the power of vitamins B6 and B12.
