Promensil Original is scientifically formulated to provide 40mg of naturally occurring & standardised Red Clover Isoflavones (phytoestrogens) to help women from within for long-term balance & dietary support during menopause. Phytoestrogens work by naturally mimicking the action of oestrogen in the body. Promensil's Red clover (Trifolium pratense) is an herbal extract which is specifically extracted for those opting for a holistic & plant-based approach to menopause & contains four main types of isoflavones: Biochanin A, Formononetin, Daidzein & Genistein, while soy only contains two: Daidzein & Genistein. These are widely used by women to maintain their health & vitality especially during the time of menopause. These isoflavones can also be obtained through diet, for example., chickpeas & soya milk; but you would need to consume a lot to get the recommended daily intake of 40-80mg of isoflavones. This is where supplementation using Promensil can help. Promensil is the most extensively studied menopause supplement & has been used in international scientific research for over 20 years into effects of red clover supplementation on menopause.
