Soybean Isoflavones

Soybean isoflavones (CAS 574-12-9) are naturally occurring phytoestrogens extracted from non-GMO soybeans (Glycine max). They consist primarily of daidzin, genistin, and glycitin—both as glycosides and their corresponding aglycones—and are standardized by HPLC to a total content ranging from 40% to 90% depending on your formulation needs. We supply them as a free-flowing powder with a consistent particle size, suitable for direct compression, encapsulation, or blending with other actives.

Our production process uses aqueous ethanol extraction followed by macroporous resin purification, which preserves the natural isoflavone profile while removing unwanted plant lipids and proteins. The finished material is tested for assay, residual solvents, and microbial limits, and each batch is accompanied by a full certificate of analysis.
