The antioxidant glutathione is known to recycle which vitamins?

Glutathione is a key antioxidant in the body that plays a crucial role in maintaining cellular health and protecting against oxidative stress. One of its significant functions is the recycling of Vitamins C and E.

Vitamin C, or ascorbic acid, is a water-soluble antioxidant that can be oxidized in the process of neutralizing free radicals. After it has done its job, glutathione helps to convert oxidized Vitamin C back to its active form, allowing it to further participate in antioxidant defense. Likewise, Vitamin E, a fat-soluble antioxidant, works by neutralizing lipid peroxyl radicals. Once Vitamin E donates an electron to neutralize a free radical, it too can become oxidized. Glutathione then assists in reducing oxidized Vitamin E back to its active form, thus prolonging its protective effects.

Understanding this relationship highlights the synergy between antioxidants and emphasizes the importance of a well-rounded diet that includes sources of these vitamins to support overall health and antioxidant defenses.
