The importance of fermented soy
Obtaining isoflavones from fermented soy means that the important active ingredients are more easily absorbed by the body.
Isoflavones found in soya beans are plant chemicals known as genistin and daidzin. These are not biologically active – they do not act as phytoestrogens.
When we ingest soya products based products, acid in the stomach and bacterial enzymes in the intestines convert these molecules to genistein and daidzein (note change from –in to –ein). It is this form of isoflavones which are active.
If you don’t have a good digestive system or gut flora, this conversion does not take place adequately – this means that you may not get the benefits of what you are taking. It is thus better to take a supplement containing isoflavones which have already been converted such as with fermented soy extracts.
Historically, soya consumption in East Asia where menopausal symptoms are unusual has been in the form of fermented soya products such as soya sauce, miso and tempeh, rather than soya milk and soya vegetable protein that is consumed in the West.
Each tablet of Menopause Support contains 42mg of fermented soya bean extract, providing 25mg of isoflavones. Of those, 11.5mg are genistein, 11.5mg daidzein and 2mg glycitein.
