Inositol

Inositol was once considered to be one of the B-complex vitamins but as it can be fully synthesised in the body, it is no longer considered to be a vitamin. It is a carbohydrate with a waxy/oily consistency and little taste, and is closely associated with vitamin B6, choline, biotin, pantothenic acid, PABA, and folic acid. Inositol is a component of phospholipids in animal tissue and phytic acid in plant cells. Inositol, like choline, help move fats out of the liver.

Inositol is essential in promoting the production of lecithin and is stored in the liver, spinal cord nerves, and in the brain and cerebral spinal fluid. Lipotropic effect, helps in the metabolism of fats. Inositol and choline have an anti-arteriosclerotic, antiatherogenic effect.
