Soybean Extract Information:

Soybean (Glycine max (L.) in latin); This member of the pea family (Fabaceae) grows from 1-5 feet tall and forms clusters of 3-5 pods that each contain 2-4 beans. species of legume native to East Asia. It is an annual plant that has been used in China for 5,000 years as a food and a component of drugs. The main producers of soy are the United States, Brazil, Argentina, China and India.

Soy isoflavones are phytochemical constituents of soybeans, a legume that has served as the basis for various foods in many Southeast Asian countries for thousands of years. The major isoflavones in soy are genistein and daidzein. Soyfoods also contain other valuable constituents, including protein, saponins, and phytosterols.

Indications and Uses:

Soybean extract can protect against cancer as well as heart disease. The mild estrogen activity of soy isoflavones may ease menopause symptoms for some women, without creating estrogen-related problems, and may help regulate hormone levels in premenopausal women. Soy isoflavones may also play a beneficial role in preventing osteoporosis and autoimmune conditions.

Benefits:
Genistein and daidzein have been well researched by scientists for their antioxidant and estrogenic properties.

Isoflavones may reduce the risk of hormone-dependent cancers, such as breast and prostate cancer, as well as other cancers. A review study of soy research found that 65 percent of 26 animal-based cancer studies showed a protective effect of soy or soy isoflavones. Human research and population studies also suggest that soy can protect against cancer as well as heart disease. The mild estrogen activity of soy isoflavones may ease menopause symptoms for some women, without creating estrogen-related problems, and may help regulate hormone levels in premenopausal women. Soy isoflavones may also play a beneficial role in preventing osteoporosis and autoimmune conditions.

A number of new studies have confirmed anti-cancer effects, more so for genistein than daidzein. Studies have also determined that soy isoflavones can help prevent bone-loss when calcium is deficient, and they can improve blood fat and cholesterol profiles and thus reduce the risk of heart disease.

Two particularly important isoflavones in soy--genistein and daidzein--appear to protect against hormone-related disorders such as breast cancer and endometriosis. They do this by competing for the same place on cells (receptor sites) that the body's own estrogen does. Some of the risks of excess estrogen, including breast and uterine cancer, can apparently be lowered in this way.

Similarly, when the body's natural levels of estrogen drop, as they do with menopause, soy isoflavones can compensate by binding to some of the cell receptor sites that estrogen once did. Menopausal symptoms may improve as a result.

Research findings suggest that soy isoflavones may also inhibit cancer-causing enzymes, provide antioxidant protection, and enhance the immune system.
