What was done
This narrative review synthesized evidence from database searches (PubMed, Web of Science, Scopus, SPORTDiscus) covering exercise physiology, redox biology, and sports nutrition. The authors reviewed short-term human intervention trials, systematic reviews, meta-analyses, and mechanistic studies examining food-based antioxidant sources (tart cherry, berries, pomegranate, cocoa, green tea, beetroot, extra virgin olive oil, and Mediterranean-style dietary patterns) to develop a conceptual framework for periodized recovery versus isolated antioxidant supplementation.
What was found
The abstract reports no numerical data or effect sizes. Qualitatively, food-based antioxidant strategies were reported to influence recovery via mechanisms extending beyond direct radical scavenging (including vascular function, inflammatory regulation, and gut-derived metabolism). Outcomes varied by food source, dose, timing, and population. The authors found no support for universal fixed daily antioxidant intake, concluding that food-based strategies are most appropriate when periodized to phases of elevated recovery demand.
Why it matters
High-dose isolated antioxidant supplements can suppress exercise-induced reactive oxygen and nitrogen species essential for training adaptation and mitochondrial biogenesis. This framework provides a rationale for using whole-food matrices to aid acute recovery without compromising chronic physiological adaptations.
Limits
The paper is a narrative review without systematic study selection, risk-of-bias assessment, or pooled meta-analytic effect sizes. The reviewed literature consists largely of short-term, heterogeneous trials. Specific quantitative dosing, timing protocols, and direct long-term adaptation outcomes are not provided in the abstract.
