What is it?
Myo-Inositol is produced in many human tissues and it is also found in many food sources. The best sources of Myo-Inositol are fruits, beans, grains, and nuts. Fresh vegetables and fruits contain more Myo-Inositol than frozen, canned, or salt-free products. Cantaloupe and citrus fruits other than lemons are very rich in Myo-Inositol and oats and bran contain more than other grains. There is very little Myo-Inositol in milk and yogurt. Myo-Inositol has been used in the treatment of liver disease, depression, panic disorder, diabetic neuropathy (damage to the nerves which results in pain and numbness), respiratory distress syndrome (found in premature babies due to poor lung development), and to treat the side effects of the medicine lithium.
Other names for Myo-Inositol include: Inositol, Inositol Monophosphate, and Inositol Hexaphosphate
