What is Genistein Powder?
Genistein is a naturally occurring isoflavone found in various legumes and medicinal plants, particularly soybeans and Sophora japonica. As a plant-derived phytoestrogen, Genistein has a chemical structure similar to human estrogen, allowing it to interact with estrogen receptors in the body and contribute to a variety of physiological functions. Due to its ability to neutralize free radicals and regulate cell signaling pathways, genistein has become a common ingredient in dietary supplements, functional foods, and cosmetic formulations.
Undersun supplies bulk genistein powder extracted from the fruit of the Sophora japonica, off-white powder, 98%, HPLC tested, exhibiting excellent stability and formulation compatibility. Our genistein has undergone heavy metal and microbial safety testing. Documentation such as COA, TDS, specification sheets, and flowcharts can be provided to ensure the safety and reliability of your formulation ingredients.
