The Main Ingredient Is: Soy Isoflavones (Genistein, Daidzein, Glycitein) from non-GMO Soy Extract

Soy isoflavones are plant compounds that come from soy and occur naturally as three main forms: genistein, daidzein and glycitein. This extract is standardised to a minimum level of overall isoflavones and is obtained via an alcohol-washed method to concentrate the active compounds.

The main ingredient is blended with non-active ingredients to form vegetarian capsules, sourced from soy as described. This formula also includes other components to support the main ingredient's role in providing phytoestrogen-like activity within normal bodily processes.

What Does Soy Isoflavones Do?

Soy isoflavones help with hormonal balance and bone health-related processes as phytoestrogens that can interact with estrogen receptors in the body. Research suggests possible effects on bone metabolism and hormonal balance through these interactions.

Dr. Arjmandi at the University of Florida found that higher isoflavone intake was linked to activity on bone mineral density markers in postmenopausal women, indicating a potential role in supporting bone health indicators.
