Inositol is a substance found in natural foods. It is mostly referred to as Vitamin B8, though it is not an actual vitamin.  It is a sugar that influences insulin response. Inositol has antioxidant properties that help in fighting the damaging effects on the brain, body tissues, and the circulatory system.

Inositol balances certain chemicals in the body that help with mental conditions like panic disorder, obsessive disorder, and depression. It also helps insulin to work well. This will helpsdeal with conditions like polycystic ovary syndrome and during pregnancy (PCOS).

What are the types of inositol?

  • Myo-inositol; is the most common type of inositol in human tissues. It mostly promotes insulin and follicle-stimulating hormone in the ovary.
  • D-chiro-inositol; is mostly formed when Myo-inositol is converted to D-chiro-inositol. It plays an important role in insulin’s action in the muscles and fats. It is proven to improve insulin and androgen.

Health Benefits of Inositol
