Inositol is fundamental for cell membranes and is necessary for proper functioning of nerves, brain and muscles in the body. It functions closely with vitamin B complex. It is primarily used in the treatment of liver problems, depression panic attacks and diabetes. It aids in the breakdown of fats, helps in the reduction of blood cholesterol levels and helps to prevent the thinning of hair. Neurotransmitters such as serotonin in the brain depend on Inositol to function properly. There appears to be some evidence that decreased levels of Inositol may have a role to play in people suffering from depression.
