- The International Society of Sports Nutrition (ISSN) provides an official position on dietary antioxidants in exercise and sports performance.
- Antioxidants have a complex role: they aid recovery but may hinder adaptations at high doses.
- Endogenous systems maintain redox balance, but dietary antioxidants help manage excessive oxidative stress.
- Effects depend on timing, dosage, type, and individual factors.
- Moderate oxidative stress supports adaptations, while excessive stress harms health and performance.
- Dietary antioxidants can neutralize free radicals and reduce oxidative damage.
- FDA-approved antioxidant claims apply to nutrients like vitamins C, E, β-carotene, selenium, zinc, copper, and manganese.
- Whole foods rich in flavonoids, polyphenols, and vitamins are preferred sources.
- Supplementation is recommended for deficiencies, inadequate intake, or high training distress.
- Top effective antioxidants include creatine monohydrate, omega-3 fatty acids, tart cherry, and astaxanthin.
- Individual responses vary based on training status, diet, and other factors.
- Exercise enhances endogenous defenses, making it the primary strategy for improving redox capacity.
