# Alpha memo: resveratrol endurance exercise cross-context evidence signal
**One-sentence alpha:** Resveratrol plus exercise may improve mitochondrial and oxidative-stress readouts in rodent skeletal muscle, but in older adults with functional limitations the same combination appears safe and feasible without yet showing clinical benefit.
**Receipt 1:** "Resveratrol and/or exercise training counteract aging-associated decline of physical endurance in aged mice; targeting mitochondrial biogenesis and function" — 18-month-old mice receiving resveratrol (15 mg/kg/day) and/or exercise training for 4 weeks showed significantly longer time to exhaustion, decreased blood lactate and free fatty acids, decreased gastrocnemius lipid peroxidation, and increased gastrocnemius catalase and superoxide dismutase activity versus aged controls, alongside overexpression of PGC-1α in skeletal muscle.
**Receipt 2:** "Resveratrol and exercise combined to treat functional limitations in late life: A pilot randomized controlled trial" — a three-arm, two-site pilot RCT in 60 community-dwelling adults (~71.8 ± 6.3 years) with functional limitations randomized participants to 12 weeks of exercise plus placebo, exercise plus 500 mg/day resveratrol, or exercise plus 1000 mg/day resveratrol, and was designed/aimed to assess safety, feasibility, adherence, physical function, and skeletal muscle mitochondrial function.
**Why this is surprising:** Rodent data made combined mitochondrial and oxidative-stress gains seem plausible, yet a 12-week human pilot at 500–1000 mg/day has not yet produced a comparable clinical signal, so the translational boundary may be population- and endpoint-specific rather than a clean mechanistic transfer.
**Caveats/falsifiers:**
- Receipt 1 is aged-mouse pharmacology (15 mg/kg/day, 4 weeks, gastrocnemius endpoints); Receipt 2 is an N=60 pilot in adults ~72 years old with functional limitations at 500–1000 mg/day resveratrol plus exercise for 12 weeks, so the moderator (species, population, duration, dose, baseline status) is tentative and confounded across multiple axes and no clinical or supplementation recommendation follows.
- Receipt 2 explicitly labels itself a safety/feasibility pilot; it does not establish improved physical function or muscle mitochondrial outcomes, so any efficacy claim is premature.
- A decisive falsifier would be an adequately powered RCT in older adults with functional limitations showing no improvement in physical function or skeletal muscle mitochondrial readouts at comparable 500–1000 mg/day dosing over ≥12 weeks.
- Receipt 1 (2018) predates Receipt 2 (2021); the later paper functions as a clinical-update pilot rather than a direct replication of the rodent mechanism.
