Isoflavones are a class of phytochemicals, which can act as estrogens in the body and have protective functions. Isoflavones are natural anti oxidants. Isoflavones occur highest amounts in soybeans (soya nuts) red clover and kudzu root and extracts from these are used in the production of nutritional supplements.

The potential health benefits are attributed to Isoflavones are:

• Isoflavones can reduce the effect of the estrogen on cells and skin layers when the hormone levels are high, and then essentially reduce the risk of estrogen linked cancers. Isoflavones may reduce the risk of hormone dependent cancers such as breast and prostate cancers.
• Isoflavones are responsible for improving cholesterol profile.
• Ease menopause symptoms - Recent studies have found that soy isoflavones can reduce menopause symptoms such as hot flushes and increase bone density in women.
• Reduce heart disease risk - Soy isoflavones can reduce cardiovascular disease risk via several distinct mechanisms. Isoflavones inhibit the growth of cells that form artery clogging plaque.
• Protect against prostate problems - Isoflavones may be beneficial for men's health because they may protect against enlargement of the male prostate gland. Studies show isoflavones slowed prostate cancer growth and caused prostate cancer cells to die. Isoflavones act against cancer cells in a way similar to many common cancer-treating drugs.
• Isoflavones improve bone health - Soy Isoflavones help in the preservation of the bone substance and fight osteoporosis.
• Reduce cancer risk - Isoflavones seem to be protecting against tumors because they act against cancer cells in a way similar to many common cancer-treating drugs.
