D-Chiro-Inositol

Amino Acids & Compounds

D-Chiro-Inositol (DCI) is a naturally occurring isomer of inositol, a sugar alcohol involved in cellular signaling pathways related to insulin activity. Research suggests that DCI plays a role in supporting healthy blood sugar metabolism by acting as a secondary messenger in insulin signaling, and studies indicate it may be particularly relevant for individuals with polycystic ovary syndrome (PCOS), where DCI levels are often found to be lower than typical. Clinical research has explored its potential to support hormonal balance, including testosterone levels and ovarian function, often in combination with myo-inositol at a 40:1 ratio that mirrors the body's natural physiological balance. While findings are promising, especially in the areas of metabolic and reproductive health, ongoing research continues to clarify the full scope of its benefits across different populations.
