Soy isoflavones are plant-derived compounds with estrogen-like activity that may interact with estrogen receptors. They are primarily studied for their potential role in mitigating menopausal symptoms like hot flashes and supporting bone density. While not a direct anti-aging intervention, they may indirectly contribute to healthspan by addressing specific age-related physiological changes.
