Vitamin C (Ascorbate)

Vitamin C (Ascorbate) structure

Overview

Vitamin C, also known as ascorbate, is a water-soluble vitamin that functions as a key antioxidant in the body. It works within antioxidant networks alongside vitamin E, CoQ10, and polyphenols, with these compounds regenerating each other to maintain antioxidant capacity. Vitamin C is essential for the synthesis of norepinephrine, serving as a cofactor in the conversion of dopamine to norepinephrine, which supports attention, arousal, and executive function. In the brain, vitamin C is actively transported via SVCT2 transporters to maintain adequate levels. Vitamin C also enhances the absorption of non-heme iron from plant sources when consumed together.
