Inositol, sometimes referred to as vitamin B8, naturally occurs in foods such as fruits, beans, grains and nuts (1Trusted Source). Your body can also produce inositol from the carbohydrates you eat. However, research suggests that additional inositol in the form of supplements may have numerous health benefits.
What Is Inositol?
Though often referred to as vitamin B8, inositol is not a vitamin at all but rather a type of sugar with several important functions. Inositol plays a structural role in your body as a major component of cell membranes. It also influences the action of insulin, a hormone essential for blood sugar control. In addition, it affects chemical messengers in your brain, such as serotonin and dopamine. It has been estimated that a typical diet in the US contains around 1 gram of inositol per day. Rich sources include grains, beans, nuts and fresh fruits and vegetables.
However, supplemental doses of inositol are often higher. Researchers have studied the benefits of doses up to 18 grams per day — with promising results and few side effects.
