Antioxidant News and Research

RSS

Antioxidants are substances that protect cells from the damage caused by free radicals (unstable molecules made by the process of oxidation during normal metabolism). Free radicals may play a part in cancer, heart disease, stroke, and other diseases of aging. Antioxidants include beta-carotene, lycopene, vitamins A, C, and E, and other natural and manufactured substances.

Unveiling Epidermal Hemoglobin: A Breakthrough in Skin Research
