This stereoisomer of inositol is a critical second messenger mediating cellular responses to insulin. Embedded in cell membranes, D-chiro-inositol is part of a glycosyl phosphatidylinositol complex that is hydrolyzed into two bioactive molecules upon exposure to insulin. These molecules regulate glucose disposal by activating pathways in which glucose is either converted to glycogen for storage or oxidatively metabolized to produce energy.† Studies show D-chiro-inositol is involved in proper insulin and glucose metabolism and may have a role in maintaining normal lipid profiles, cardiovascular function, and ovarian function.† It may also help regulate inflammatory stress and modulate serotonin activity.† Derived from carob pods, D-Chiro-Inositol is recommended to support normal insulin function and blood sugar metabolism.†
