What is the function of antioxidants?

The main function of antioxidants is to eliminate free radicals in the body, reduce their oxidative damage to cells, and thereby protect biomolecules such as cell membranes, DNA, and proteins. Specifically, antioxidants can act as donors or acceptors that react with free radicals, neutralizing their strong oxidizing properties and eliminating damage to biomolecules. This process helps delay aging, enhance immunity, prevent diseases (such as diabetes and cardiovascular disease), and protect the eyes and skin. Antioxidants also help the body resist harmful environmental pollutants and maintain cellular health and normal function. However, not all antioxidants are suitable for everyone, and excessive intake of certain antioxidants may produce negative effects. Therefore, appropriate intake should be based on individual physical conditions and needs.
