As a powerful electron donor, it works at the frontline of antioxidant defense by: Directly neutralizing superoxide, hydroxyl, and peroxyl radicals Regenerating oxidized vitamin E, allowing it to continue its antioxidant function Supporting collagen synthesis, which is essential for wound healing and skin health Enhancing immune function through multiple mechanisms While effective, vitamin C has limitations including poor penetration into fatty tissues, rapid excretion from the body, and potential pro-oxidant effects at very high doses
Different peptides have different effects: some promote healing, some enhance growth hormone release, some improve sleep, skin, or cognition
