# Alpha memo: resveratrol exercise context boundary **One-sentence alpha:** A pilot suggested combining resveratrol with exercise is safe and feasible in older adults with functional limitations, while a separate trial in aged men suggests exercise, but not 250 mg/day resveratrol, improved skeletal muscle metabolic and inflammatory markers. **Receipt 1:** Resveratrol and exercise combined to treat functional limitations in late life: A pilot randomized controlled trial (2021) — A three-arm, two-site pilot RCT (N = 60, mean age 71.8 ± 6.3) randomized community-dwelling older adults with functional limitations to 12 weeks of exercise plus 0, 500, or 1000 mg/day resveratrol, designed to evaluate safety and feasibility of the combination alongside physical-function and muscle mitochondrial outcomes. **Receipt 2:** Exercise training, but not resveratrol, improves metabolic and inflammatory status in skeletal muscle of aged men (2014) — In healthy inactive men aged 60–72 randomized to 8 weeks of 250 mg/day resveratrol or placebo, with or without high-intensity exercise, exercise training increased skeletal muscle PGC-1α mRNA ~1.5-fold and cytochrome c oxidase I protein ~1.5-fold while resveratrol did not produce a reported additive effect on these metabolic and inflammatory endpoints. **Why this is surprising:** Receipt 1 made plausible that layering resveratrol onto exercise in older adults with functional limitations is deliverable and worth testing, but Receipt 2 suggests that even when combined with exercise in aged men, resveratrol did not add detectable improvement over exercise alone on muscle metabolic/inflammatory markers. **Caveats/falsifiers:** - Receipt 1 is a pilot (N = 60) reporting small-sample feasibility/safety outcomes, not functional-performance efficacy, and Receipt 2 used a lower 250 mg/day dose over 8 weeks versus 500–1000 mg/day over 12 weeks in older adults with functional limitations, so the moderator hypothesis for the contrast (dose, duration, baseline status, population) is tentative and confounded by these other axes. - A decisive future falsifier would be an adequately powered trial in older adults with functional limitations showing an additive resveratrol-on-exercise effect on a pre-specified muscle or function endpoint.
