Soy

Soy (Glycine max) is a legume native to East Asia, cultivated for thousands of years for its seeds, which are rich in protein, lipids, and micronutrients. It is one of the most complete plant-based protein sources, providing all essential amino acids. It is found in many forms in food and supplementation: oil, flour, isolated proteins, lecithin, and isoflavone extracts. Soy is particularly well known for its isoflavone content, phytoestrogens that have been the subject of numerous studies. These compounds contribute to hormonal balance, especially in women during menopause, and are associated with support for bone and cardiovascular comfort. Soy lecithin is recognised for its role in normal lipid metabolism. In supplementation, standardised soy extracts in isoflavones or lecithin allow precise and reproducible doses tailored to specific needs. This approach is especially relevant for people whose diet is low in soy sources or who are looking for a targeted intake of phytoestrogens.
