The Active Ingredient Is: Inositol (Myoinositol)

Inositol is a naturally occurring compound that forms part of cell membranes and is involved in neurotransmitter signalling. This product provides pharmaceutical-grade inositol, supplied as a single-ingredient powder for pure, uninterrupted sourcing.

This form is derived from inositol with the purity expected of pharmaceutical standards, and is suitable for vegetarian and vegan diets as a clean, additive-free ingredient.

What Does Inositol Do?

Inositol is involved in the production of inositides that enable healthy cell-to-cell communication in neural, hepatic and muscular tissues and it plays a role in metabolic processes and nerve impulse transmission.

This supports normal neural function and cellular signalling, aligning with recognised nutrient functions for maintaining everyday bodily processes.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
