Designed to support hormonal balance and ovarian function, this product delivers 2,000mg of **Myo-Inositol** per serving — right at the low end of the 2,000–4,000mg clinical range studied in PCOS and insulin sensitivity trials. You're getting the minimum effective dose, which many women find sufficient.

**D-Chiro Inositol** is included at 50mg, maintaining the 40:1 ratio with myo-inositol that mirrors your body's natural balance. This ratio has been specifically studied for reproductive health support and is considered more effective than myo-inositol alone for hormonal goals.

The four-capsule serving size is the main tradeoff. At 120 capsules you're getting 30 days of use, so a monthly repurchase is necessary. If you want to push toward the higher end of the clinical range (4,000mg myo-inositol), you'd need to double the serving — and the bottle would last only two weeks.
