Inositol is present as phytic acid in corn (Zea mays) and rice (Oryza sativa) bran. Corn or rice bran needs to go through a series of processes including hydrolysis, filtration, concentration, and crystallization to produce fine crystalline inositol that is digestible and available to humans.

Major Health Benefits

Inositol is a component of phosphatidylinositol, a phospholipid that is an enzyme modulator and key component of cell membranes and lipoproteins. Inositol is an important factor for normal cell growth and development and thus may play a role in normal fetal and neonatal development1. Inositol may also regulate calcium release and insulin action within the cell, improving insulin sensitivity and glucose utilization.2,3 Inositol may also reduce the risk of diabetes during pregnancy.4
