Klaire labs D Chiro Inositol D chiro inositol is involved in proper insulin and glucose metabolism and helps to maintain normal lipid profiles, blood sugar metabolism, cardiovascular function, and ovarian function. May also help regulate inflammatory stress and modulate serotonin activity. 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. Recommended Use: 1 capsule twice daily with food or as directed by a healthcare professional.
