Inositol is a carbohydrate that plays a crucial role in cellular signaling and is often classified as a type of sugar alcohol. It is found in various foods, including fruits, beans, grains, and nuts. Inositol is important for the formation of cell membranes and is involved in the regulation of neurotransmitters, which can affect mood and mental health. Inositol is commonly used as a dietary supplement, particularly for conditions like polycystic ovary syndrome (PCOS) and anxiety disorders. Research suggests that it may help improve insulin sensitivity and support ovarian function. While generally considered safe, it's advisable to consult a healthcare professional before starting any new supplement.
