Inositol is widely studied for its ability to improve insulin sensitivity, lower blood sugar, and regulate hormones. It is heavily utilized as a natural alternative or adjunct to medications like Metformin to restore ovulation, improve egg quality, and manage symptoms in women with polycystic ovary syndrome (PCOS). The most researched form for metabolic and reproductive support is a 40:1 ratio of myo-inositol to d-chiro-inositol.
