For hormonal balance and metabolic support, this delivers 2,000 mg of **Myo-Inositol** per 4-capsule serving — right at the bottom of the 2,000-4,000 mg range studied in PCOS and insulin sensitivity trials. The 50 mg of **D-Chiro Inositol** maintains the 40:1 ratio that mirrors your body's natural inositol balance, a ratio specifically studied in women with PCOS.
The directions suggest 1-2 servings daily (4-8 capsules). At two servings, you reach 4,000 mg myo-inositol — the dose used in the largest PCOS clinical trials showing improvements in ovulation, insulin markers, and hormonal profiles. That flexibility lets you start low and adjust based on your response.
The tradeoff is pill burden. Getting to the higher clinical dose means 8 capsules per day. This is the 120-count bottle (30 servings at the base dose, or 15 at the full clinical dose), so if you plan to use 2 servings daily, you will go through this bottle in about two weeks.
