Inositol or Myo-inositol is the wonder Vitamin supplement that will be covered in detail here.

What Is Inositol?

Inositol (also known as myo-inositol) is a naturally occurring nutrient and a glucose isomer which is used to form phospholipids in the body. Phospholipids work as cellular mediators for signal transduction in our body along with contributing towards body growth and metabolic functions. Inositol has nine distinct isomers and myo-inositol is the most popular among the lot. This supplement is synthesized in our body using Glucose 6 phosphate.

Inositol is available from natural sources and can also be made from synthetic sources in laboratories. Inositol is needed for the proper functioning of our brain, intestine, cells and for nerve growth & nerve communication. Along with Choline, Inositol helps in removing fat from the heart and liver, and also produces Lecithin. Lecithin is a type of lipid that is responsible for the production of cell membranes and also helps in absorption of Thiamin and Vitamin A in the body.

Apart from Myo-Inositol, other forms of Inositol include – Inositol Hexaphosphate (may have anti-cancer properties), D-Chiro-Inositol (helps women with PCOS) and Inositol Hexaniacinate/Inositol Hexanicotinate (for reducing cholesterol & triglycerides).

Inositol helps in neuro communication and also in the smooth functioning of the entire nervous system by releasing two natural sedatives – serotonin and acetylcholine. Similarly, Myo-inositol is made from glucose-6-phosphate and converted to phosphatidylinositol. Phosphatidylinositol is one of the most important components of the cell membranes.
