# Alpha memo: resveratrol exercise training cross-context signal
**One-sentence alpha:** Resveratrol's effect during exercise training appears to depend on context, with rodent data suggesting intestinal protection and human data suggesting attenuation of cardiovascular gains.
**Receipt 1:** "Resveratrol attenuated high intensity exercise training-induced inflammation and ferroptosis via Nrf2/FTH1/GPX4 pathway in intestine of mice" (2023) — in mice given swimming high-intensity exercise plus 15 mg/kg/day resveratrol for 28 days, resveratrol reduced intestinal inflammatory factors and permeability markers relative to exercise-only mice, with authors proposing Nrf2/FTH1/GPX4 signaling as the mechanism.
**Receipt 2:** "Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men" (2013) — in 27 healthy inactive aged men randomized to 250 mg/day trans-resveratrol or placebo during 8 weeks of high-intensity training, the resveratrol group showed attenuated training-induced increases in maximal oxygen uptake versus placebo, with MAP and other cardiovascular parameters reported.
**Why this is surprising:** Receipt 1 made plausible a "protective adjunct" framing of resveratrol during high-intensity training, but Receipt 2 in aged men instead suggests the same combination can reduce a key exercise adaptation.
**Caveats/falsifiers:**
- Receipt 1 is a murine intestinal inflammation/ferroptosis study, while Receipt 2 is a small (n=27) human cardiovascular/V̇O₂max trial in aged men; species, tissue (intestine vs. cardiovascular system), dose (15 mg/kg/day vs. 250 mg/day), duration (28 d vs. 8 wk), and baseline population differ, so this is a heterogeneous cross-context signal and the moderator hypothesis (age, dose, tissue) is tentative and confounded by these other axes.
- A decisive falsifier would be a randomized human trial in a comparable aged population using a comparable dose/duration that shows resveratrol does not reduce exercise-induced gains in V̇O₂max or related cardiovascular endpoints.
- Receipt 2's sample is small (resveratrol n=14, placebo n=13) and limited to healthy aged men, limiting generalizability.
