About Nature’s Sunshine Phyto-Soy
For centuries, soybeans have been valued as one of the “five ancient grains” in traditional Chinese culture, honored for their exceptional nutritional properties. Nature’s Sunshine Phyto-Soy harnesses the power of these remarkable legumes through a concentrated extract that delivers meaningful amounts of beneficial plant compounds called isoflavones.
Isoflavones are naturally occurring phytoestrogens—plant-derived compounds that have a similar structure to human estrogens but are much weaker in activity. These unique molecules may help support the body’s natural hormone balance, particularly during times of hormonal transition. The three primary isoflavones found in soybeans are genistein, daidzein, and glycitein, each contributing to the overall benefits of soy supplementation.
What sets Phyto-Soy apart from other soy products is its exceptional concentration of active compounds. Each capsule contains 120 mg of standardized soy bean extract, providing 12 mg of isoflavones. This means you get the equivalent benefits of eating large amounts of soy foods in a convenient, concentrated form. In fact, Phyto-Soy contains 48 times more isoflavones than the same amount of tofu, 25 times more than tempeh, and 10 times more than roasted soybeans.
The Science Behind Soy Isoflavones
Research has shown that populations with higher soy consumption tend to experience different health patterns, particularly regarding hormonal balance and cardiovascular wellness. The isoflavones in soy appear to work by gently modulating estrogen activity in the body. When estrogen levels are high, isoflavones may have a mild blocking effect, and when levels are low, they may provide gentle estrogenic support.
Genistein, one of the primary isoflavones in Phyto-Soy, has been extensively studied for its potential benefits. This compound may support healthy cellular function and has been investigated for its role in maintaining cardiovascular health. Daidzein and glycitein contribute additional complementary effects, working together to provide comprehensive support.
