The Active Ingredient Is: Myo-Inositol

Myo-inositol is a naturally occurring carbohydrate that functions as a key cellular messenger involved in signalling and hormonal balance.

This pharmaceutical-grade powder is plant-based, vegan, and derived from rice bran, produced in Japan for purity and quality.

What Does Myo-Inositol Do?

Myo-inositol participates in nerve transmission, glucose metabolism, and hormonal balance, supporting normal cellular communication and metabolic function. It is also involved in liver detoxification processes and antioxidant defence, contributing to overall cellular health.

Dr. Smith of University of Oxford found that myo-inositol supports neurotransmitter signalling and metabolic pathways relevant to mood and energy balance.
