D-Chiro Inositol (DCI) is a member of a family of substances referred to as inositols and generally considered to fall within the B vitamin complex.It can be found in small amounts in a range of foods such as buckwheat, chickpeas, soya lecithin, pumpkin and pumpkin seeds as well as in the Ayurvedic herb bitter melon (momordica charantia). It is also produced by healthy human bodies from d-pinitol and myo-inositol, both of which are relatively abundant in the average diet. It is a nutrient found in the body itself, which allows the body's cells to recognise it better and not reject it. 1994, the US Dietary Supplement Health and Education Act approved D-chiral inositol as a dietary supplement.
