# Alpha memo: resveratrol exercise training cross-context evidence signal **One-sentence alpha:** In mice, resveratrol may protect intestinal tissue from high-intensity exercise-driven inflammation and ferroptosis-related signalling, while in aged men the same molecule may attenuate training-related cardiovascular adaptations, suggesting a heterogeneous cross-context signal rather than a unidirectional effect. **Receipt 1:** Resveratrol attenuated high intensity exercise training-induced inflammation and ferroptosis via Nrf2/FTH1/GPX4 pathway in intestine of mice (2023) — 28 days of resveratrol (15 mg/kg/day) in a mouse swimming high-intensity exercise model reduced inflammatory factors and intestinal permeability markers. **Receipt 2:** Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men (Gliemann et al. 2013, J Physiol) — 8 weeks of 250 mg/day trans-resveratrol with high-intensity training in 27 healthy inactive aged men produced a lower training-induced increase in maximal oxygen uptake versus placebo (abstract states the training effect was reduced; the precise magnitude requires full-text verification). **Why this is surprising:** The two receipts share anchor (resveratrol + exercise training) but land on opposite directions: a protective intestinal signal in mice versus a blunted cardiovascular adaptation in aged men, so the same molecule does not behave as a uniform ergogenic. **Caveats/falsifiers:** - Multiple axes differ (species, tissue, dose 15 mg/kg vs 250 mg/day, route, duration 28 d vs 8 wk, baseline status young mice vs aged men, n=27), so the tissue- and population-dependent framing is tentative and the moderator cannot be isolated; the full text of Receipt 2 is needed to confirm the exact VO2max attenuation figure before quoting a magnitude. - Mechanistic candidates (Nrf2/FTH1/GPX4 in intestine vs Sirt1/AMPK-linked antioxidant pathways in vasculature) remain speculative and are not directly compared in either receipt. - Receipt 2's headline verb "blunts" is preserved from the title; the underlying abstract reports a reduced training-induced VO2max increase with resveratrol, not a null or worsening of baseline cardiovascular function. - No clinical, dosing, or supplementation recommendation follows from these two receipts; later 2023 work is mechanistic tissue context, not a clinical update or replication of the 2013 human trial. - Decisive falsifier: a randomised human trial in aged men showing resveratrol does not attenuate (or enhances) training-induced VO2max and vascular adaptations at equivalent dosing and training load would overturn the Receipt 2 signal.
