Abstract
Antioxidants, found in fruits, vegetables, and supplements, help prevent cellular damage by neutralizing free radicals. They are believed to reduce the risk of chronic diseases like cancer and heart conditions. However, excessive use of supplements may have adverse effects, questioning their overall health benefits. A literature review of studies from the past decade was conducted, focusing on natural sources and synthetic supplements. Data were assessed on antioxidant intake, its effect on oxidative stress, disease prevention, and side effects. Natural dietary antioxidants reduce oxidative stress and are linked to lower chronic disease risks. High-dose supplements show mixed outcomes; they benefit those with deficiencies but may disrupt cellular balance when overused. The health impact depends on the source, dosage, and individual health. Antioxidants support health best when consumed through a balanced, natural diet. High-dose supplementation should be cautious to avoid potential health risks. Further research is needed to determine optimal intake levels.
