Inositol is a naturally occurring compound, and despite being derived from glucose it is closely associated with the vitamin B-complex and exists in 9 different structures, the most common and bioavailable form is myo-inositol. This structure can be produced in the body and may also be found in nature, such as in fruits, beans, grain and nuts. Inositol plays an important role in hormonal health, nerve function and blood glucose maintenance. Inositol influences insulin signalling, the hormone responsible for lowering blood-glucose levels, and, in some cases, may support the body’s sensitivity to insulin production. Well maintained blood glucose levels may contribute to improved overall wellbeing, particularly in individuals with hormonal imbalances such as PCOS and PMDD.
Inositol is also used in the body as the structural foundation of secondary messengers, which our neurotransmitters rely upon to relay messages between brain cells. The neurotransmitters involved in this messaging system include serotonin, dopamine, GABA and acetylcholine, which manage our mood, sleep, memory, calmness and happiness throughout each day. Inositol, taken in the recommended dose, has shown to support wellbeing, particularly in female hormonal health.
