Inositol is a water soluble nutrient that is often associated
with B vitamins. While its role in human nutrition is a source of ongoing debate, it was
finally recognized as a vitamin in 1940. Chemically inositol is a sugar which is
metabolized slowly and without the involvement of insulin. Inositol is found in cell
membranes throughout the brain and central nervous system, the muscles, heart tissues,
reproductive organs, and bones. It is also involved in the transportation and metabolism
of fatty acids and cholesterol, and is a component of lecithin and several enzymes. This
nutrient is also a hydroxyl free-radical scavenger that may aid in treating arthritis.
