Nutritional Supplement, Vitamin C 1000Mg Fast Absorption The Vitamin C Is Necessary For The Synthesis Of Collagen And Is An Important Structural Component Of Blood Vessels, Tendons, Ligaments And Bones. It Also Plays An Important Role In The Synthesis Of Norepinephrine (A Major Neurotransmitter). In Addition, It Is Needed For Carnitine Synthesis (Transfer Of Fatty Acids To Mitochondria). Recent Studies Have Shown That It Is Involved In Cholesterol Metabolism In Bile Acids, Which Affect Cholesterol Levels In The Blood And Are Responsible For The Appearance Of Stones In The Bile. Also The Vitamin Cincreases Iron Bioavailability From Foods, Enhancing The Intestinal Absorption Of The Mineral Iron. The Vitamin C Is A Highly Effective Antioxidant And Protects Both Against Free Radicals, And The Active Oxygen Species Generated During Normal Metabolism. It Has The Ability To Regenerate Vitamin E. A Recent Study In Smokers, Found That C Regenerates Vitamin E From Its Oxidized Form. The Vitamin C Stimulates The Production And Function Of White Blood Cells, Especially Neutrophils, Lymphocytes And Phagocytes. The Vitamin C Protects The Integrity Of The Immune System Cells. Neutrophils, Mononuclear Cells, Phagocytes And Lymphocytes Accumulate Vitamin C At High Concentrations And Protect These Cell Types From Oxidative Damage. When There Are "Invaders," Phagocytes Release Radicals Of Peroxide, Hypochlorite, And Other Oxidants. These Active Forms Of Oxygen Kill "Invaders" But In This Process They Are Simultaneously Oxidized.
