The Active Ingredient Is: Myo-Inositol

Myo-Inositol is a natural nutrient that helps with cellular signalling and insulin pathways. This product blends myo-inositol with another inositol isomer in a 40:1 ratio to support hormonal balance and ovarian function in a reproductive wellness setting.

This formulation also includes another inositol isomer, D-chiro-inositol, which supports the primary role of myo-inositol in metabolic and reproductive processes.

What Does Myo-Inositol Do?

Myo-inositol helps support insulin signalling and ovarian hormone regulation, contributing to normal metabolic and reproductive function in line with EFSA guidance. Research suggests it may support ovarian function and menstrual regularity through its involvement in cellular pathways related to glucose metabolism.

Dr. Genazzani of the University of Pisa found that myo-inositol acts as a second messenger in pathways controlling glucose metabolism and hormone signalling.
