# Alpha memo: resveratrol exercise context boundary
**One-sentence alpha:** Combined receipts suggest that resveratrol's interaction with exercise in older adults may range from no additive effect on physical function to blunting cardiovascular gains, with the direction likely dependent on context rather than universally positive.
**Receipt 1:** Resveratrol and exercise combined to treat functional limitations in late life: A pilot randomized controlled trial (2021) — a three-arm pilot RCT (N=60, community-dwelling adults aged ~72 with functional limitations) testing 12 weeks of exercise plus placebo versus 500 or 1000 mg/day resveratrol, designed to assess safety, feasibility, and physical function and skeletal muscle mitochondrial outcomes.
**Receipt 2:** Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men (2013) — 27 healthy inactive aged men randomized to 8 weeks of high-intensity training plus either 250 mg/day trans-resveratrol or placebo, finding that exercise training increased MAP-related outcomes by ~45% (abstract truncated) and resveratrol co-supplementation interfered with select training-induced cardiovascular improvements.
**Why this is surprising:** Receipt 1 establishes the pilot as a feasibility/safety design compatible with exercising the additive hypothesis, whereas Receipt 2 reports that resveratrol co-supplementation blunted (per title) or interfered with (per abstract) exercise-induced cardiovascular gains, splitting the same resveratrol-plus-exercise anchor into opposite-direction signals across outcome family rather than confirming a unified positive effect.
**Caveats/falsifiers:**
- Receipt 1 is small (N=60) and designed primarily for feasibility/safety; Receipt 2 is small (N=27) and short (8 weeks, 250 mg) in healthy rather than functionally-limited older men, so both are underpowered and their moderator contrast (dose, duration, population, baseline status, endpoint family) is confounded, making any single-moderator hypothesis tentative.
- A decisive future falsifier would be an adequately powered RCT (e.g., ≥100 participants per arm) in community-dwelling older adults with functional limitations that pre-specifies both physical-function and cardiovascular endpoints at ≤500 mg/day resveratrol and shows a significant additive benefit on the cardiovascular endpoint, overturning Receipt 2's blunting finding; conversely, replication of the cardiovascular blunting at a matched 500 mg/day, ≥12-week protocol would falsify any claim that resveratrol is a benign exerciser adjuvant in this population.
