• About this item.
• Best C featuring Quali -C provides a brand of ascorbic manufactured in Scotland prized for its quality and reliability.
• C is essential to the biosynthesis of the c facilitator L-carnitine, the neurotransmitter norepinephrine, and the main connective tissue in the body, collagen.
• Ascorbic is invaluable to the body for its role as an electron donor, supporting numerous c enzymes in addition to enhancing the body's total antioxidant potential.
• Gluten Free, Non-GMO, Vegan.

C is a key compound in the body’s “antioxidant network,” a chain of synergistic, inextricability linked, well-studied antioxidants that includes glutathione (GSH) and E. When E uses its antioxidant function in neutralizing free radicals, it also loses this antioxidant function. C can change this status; it can regenerate E back to its native form, and is thought to “spare” glutathione in the body as well. Importantly, when ascorbate donates an electron and becomes itself oxidized, or “consumed,” the ascorbate radical is relatively harmless. In a double-blind, placebo-controlled study in which blood GSH was measured in y subjects at several stages, 500 mg of C taken daily for 2 weeks significantly raised erythrocyte (red blood cell) glutathione levels. The researchers concluded that C supplementation at that level can benefit the overall antioxidant capacity of the blood. In another study of similar design, 1000 mg of C taken daily for 4 weeks bolstered E and glutathione content in erythrocyte cell membranes, compared with placebo. The highest concentrations of C in the body are found in the central nervous system (in neurons of the brain & spinal cord) and the adrenal glands. Although the presence of ascorbate in neurons is in part explained by its neuromodulatory enzyme activity, its high concentration suggests that C is so greatly retained by neurons in order to address the higher rates of oxidative sm experienced by the brain. This has led to the conclusion that under normal conditions, C helps safeguard the integrity of neurons (and therefore the brain), largely through neutralization of the free radicals of reactive oxygen species (ROS). Low levels of blood C and the resulting accumulation of ROS are thought to be detrimental—especially to aging populations.
