Cyclohexane-1,2,3,4,5,6-hexol, commonly known as inositol (particularly myo-inositol), is a naturally occurring carbocyclic sugar used primarily as a dietary supplement and in pharmaceutical applications. It functions as a second messenger in cellular signaling pathways, supporting insulin sensitivity, neurotransmitter function, and lipid metabolism. Commonly used to manage conditions like polycystic ovary syndrome (PCOS), anxiety, depression, and metabolic disorders. Also serves as an excipient in drug formulations and is found naturally in foods such as fruits, beans, grains, and nuts. Unlike sugar alcohols, it has minimal sweetness and low caloric impact but does not exhibit significant dental health benefits.
