Inositol supplements offer a variety of benefits including maintaining cell membrane structure and liquefying fats for transportation throughout the body. Along with the nutrient choline, inositol is a lipotropic agent, and both help promote brain and memory health. Inositol comes from glucose in the body and can also be obtained through the diet. Some foods that contain inositol are whole grains, citrus fruits, green leafy vegetables and legumes. Deficiencies are rare due to it being produced and stored by the body. Inositol is available in supplement and powder form to best suit your nutritional needs.
