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.
