Article: 11 Standout Supplements for Hormone Balance—at Any Age, Let’s Talk Inositol: A Key to Hormone Balance & Ovulation

Answer: Myo-inositol supports follicle signaling; D-chiro-inositol is involved in insulin signaling—together, 40:1 is commonly studied in PCOS.

Myo-inositol and D-chiro-inositol serve complementary but distinct roles in the body, particularly for women with PCOS. Myo-inositol is the main form found in the ovaries and plays a crucial role in helping follicles mature and respond to hormones like FSH. D-chiro-inositol is what the body normally converts some myo-inositol into through an insulin-dependent enzyme. However, in women with PCOS, this conversion process is often impaired, leading to an imbalance between the two forms. That’s why supplementing with both in the body’s natural 40:1 ratio (myo-inositol to D-chiro-inositol) is more effective than taking either alone—it mimics what your body is trying to do naturally and helps restore proper hormone balance more effectively than single-ingredient supplementation. Perelel’s Hormonal Balance Support contains the clinically-backed optimal 40:1 inositol ratio.
