The Active Ingredient Is: Inositol (Myo-Inositol)

Inositol, including its myo- form, is a carbohydrate-like molecule that functions as a cellular messenger and supports healthy cell membrane function. It acts as a precursor in cellular signalling pathways involved in communication between cells.

This form comes in a vegetarian capsule containing pure inositol, suitable for general wellness support and cellular health purposes.

What Does Inositol Do?

Inositol helps with neurotransmitter signalling and insulin signal transduction, supporting normal brain function and metabolic processes. It plays a role in key cellular communication pathways that underlie mood balance and energy regulation.

Its role in these cellular mechanisms lines up with its described functions in cellular health and metabolic support contexts.
