D-Chiro-Inositol is a naturally occurring isomer of inositol, a type of sugar alcohol involved in various cellular processes. It plays a crucial role in insulin signaling, hormonal balance, and glucose metabolism.

This compound is particularly known for its benefits in polycystic ovary syndrome (PCOS), where it helps improve ovarian function, menstrual regularity, and insulin sensitivity. D-Chiro-Inositol also supports metabolic health, potentially aiding in the management of type 2 diabetes, weight control, and cardiovascular function.

Often used as a dietary supplement, it is available alone or combined with myo-inositol for synergistic effects in women’s health formulas.
