Inositol is primarily used for the storage and metabolism of amino acids. It is an important part of the citric acid cycle, or the main series of chemical reactions that leads to the conversion of food into energy. Inositol may also benefit the immune system, hair health, and manage other conditions such as Alzheimer's disease and diabetic nerve pain.
Furthermore, inositol may help manage mental health concerns. Holistic psychiatrists recommend nutritional supplements like inositol, tryptophan and omega-3 fats for bipolar disorder patients. Inositol may also help those diagnosed with panic disorder, depression and obsessive-compulsive disorder. A 2010 study found that inositol may help minimize the symptoms of psoriasis and promote mood stabilization for people with bipolar disorder.
