Inositol is a type of sugar that helps make cell membranes and regulate insulin levels. Inositol may be beneficial for people with conditions like polycystic ovary syndrome (PCOS) and metabolic syndrome.
The Food and Drug Administration (FDA) considers inositol to be generally safe, but some people may experience mild side effects if they take higher dosages.

People with metabolic syndrome have several risk factors for cardiovascular disease and type 2 diabetes. These may include obesity, high blood pressure, and high blood glucose. According to a
Additionally, raised glucose levels lower myoinositol levels in a person’s tissues. The body breaks down the myoinositol faster, and the kidneys eliminate it faster, creating a vicious cycle.
The study authors highlight the many studies demonstrating the safety of myoinositol. They conclude that doctors should consider it as a treatment for people with metabolic syndrome, as well as those with diabetes.
Additionally, inositol clinical trials tend to last no longer than 1 year, so it is unclear whether inositol is safe to take in the long term.

People can also eat foods containing substances that the body uses to make inositol, such as:
Inositol is a type of sugar that helps form the structure of cell membranes. It also regulates insulin and neurotransmitters. The human body can make inositol, but people can also get it from supplements and some foods.
