Soy isoflavones are plant-based compounds with gentle estrogen-like activity, classed as a functional nutrient for supporting normal physiological processes. This formula uses a standardised soy isoflavone extract to offer a steady profile of active components, sourced from soy to maximise bioavailability.

The extract is presented as Novasoy soy isoflavone concentrate, standardised to 40 percent isoflavones with genistein, daidzein and glycitein as typical components. This form is described as bioavailable and is used to support the intended nutritional profile of the product.

What Does Soy Isoflavones Do?

Soy isoflavones may support cardiovascular and bone health in postmenopausal women, and can contribute to metabolic and cellular maintenance through phytoestrogenic activity. They may help maintain healthy blood lipid levels and glucose metabolism, and provide antioxidant activity within a broad nutritional context.

Evidence indicates the estrogen-like activity of soy isoflavones can influence bone and heart-related aspects of health, while supporting normal cell signalling and vascular function as part of an overall balanced diet. This aligns with EFSA- and NHS-informed understandings of nutrient function.
