Antioxidant supplements are dietary products designed to provide the body with compounds that help neutralize free radicals and unstable molecules that can cause cellular damage and contribute to aging and various diseases. These supplements often contain vitamins such as C and E, minerals like selenium, and other nutrients such as beta-carotene and coenzyme Q10. While antioxidants are naturally present in fruits, vegetables, and other whole foods, supplements offer a concentrated source that some believe can enhance health, support the immune system, and potentially reduce the risk of chronic conditions like heart disease and cancer. However, the efficacy and safety of these supplements can vary, and their use should be considered in the context of a balanced diet and overall lifestyle.
