OVARIAN & MENSTRUAL SUPPORT: with an evidence-based blend of myo-inositol and d-chiro inositol, Ovasitol is designed to promote optimal hormone levels in support of ovarian health, regular menstrual cycles, and fertility.* 90-day supply. 2X MORE INOSITOL: Ovasitol provides the clinically studied daily dose of 4,000mg myo-inositol and 100mg of d-chiro inositol, which is 2x more inositol per day than the other brands. OPTIMAL FORMULA: Each dose contains 2,000 mg myo-inositol and 50mg of d-chiro inositol to be taken twice per day, for a total daily dose of 4,000mg myo-inositol and 100mg of d-chiro inositol. This is the body’s normal ratio of 40:1. Studies have shown that taking a combination of these two forms, in this ratio, may be more beneficial than taking myo-inositol or D-chiro inositol alone.* Ovasitol is the least expensive, full-dose, 40:1 inositol supplement. EVIDENCE-BASED: Studies show inositol promotes healthy insulin levels, and supports regular menstrual cycles and ovarian health.* Ovasitol has been chosen for use in multiple university-based clinical trials. QUALITY: Made in the USA in a cGMP registered facility. Ovasitol is the first and only inositol supplement independently tested and certified by NSF International, an independent non-profit organization which verifies content accuracy, quality, and freedom of contaminants such as heavy metals.
