# Alpha memo: resveratrol exercise training translation boundary
**One-sentence alpha:** Resveratrol paired with exercise may help in a mouse high-intensity swimming gut-injury model yet tends to blunt training-induced cardiovascular gains in aged men, hinting that the same anchor splits by outcome family and population.
**Receipt 1:** Resveratrol attenuated high intensity exercise training-induced inflammation and ferroptosis via Nrf2/FTH1/GPX4 pathway in intestine of mice — in mice given a 28-day swimming protocol with 15 mg/kg/day resveratrol, the paper reports effects on inflammatory factors and intestinal permeability consistent with attenuation of high-intensity exercise-induced gut injury.
**Receipt 2:** Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men — in 27 healthy inactive aged men randomized to 250 mg/day trans-resveratrol or placebo with high-intensity training for 8 weeks, the abstract reports that resveratrol was associated with blunting of training-induced cardiovascular health improvements.
**Why this is surprising:** Receipt 1 (mouse mechanistic study) made plausible that resveratrol would act as a clean add-on to exercise, whereas Receipt 2 updates that picture by suggesting the same combination can interfere with a different endpoint (cardiovascular) in older humans.
**Caveats/falsifiers:**
- Receipt 1 is a 28-day, 15 mg/kg/day swimming + resveratrol mouse model focused on gut endpoints and does not establish cardiovascular benefit; Receipt 2 used 250 mg/day for 8 weeks in men ~65 years old, so species, dose, route-equivalence, duration, sex, baseline status, and sample size (n=27, split 14 vs 13) all differ and confound any single-moderator explanation.
- A decisive falsifier would be a randomized trial in aged (or younger) men that restores a positive additive cardiovascular effect of trans-resveratrol + high-intensity training at ≥250 mg/day over ≥8 weeks, matching training load and MAP/V̇O₂max endpoints to Receipt 2.
