# Alpha memo: resveratrol exercise context boundary
**One-sentence alpha:** Resveratrol combined with exercise may improve functional outcomes in older adults with limitations, but the same pairing can suggest attenuated rather than additive cardiovascular gains in healthy aged men, indicating a context-dependent split rather than a uniform synergy.

**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, mean age ~72) randomized community-dwelling adults with functional limitations to 12 weeks of exercise plus placebo, 500 mg/day resveratrol, or 1000 mg/day resveratrol, and was designed to assess safety/feasibility, physical function, and skeletal muscle mitochondrial outcomes (abstract cuts off before numeric results).

**Receipt 2:** Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men (2013) — in 27 healthy inactive aged men (~65 y), 8 weeks of high-intensity exercise training combined with 250 mg/day trans-resveratrol vs placebo resulted in a training-induced increase of ~45% (units truncated in abstract) that was blunted in the resveratrol group compared with placebo on the cardiovascular parameter reported.

**Why this is surprising:** A polyphenol repeatedly framed as ergogenic in animal work suggests clean additivity with exercise, yet the one human trial reporting a directional contrast shows the opposite direction on cardiovascular endpoints, suggesting population, dose, and endpoint may all matter.

**Caveats/falsifiers:**
- Receipt 1 is a small pilot (N = 60) with the abstract cut off before endpoint results, so the design only establishes feasibility/safety framing rather than an observed functional benefit; Receipt 2 is a small sample (n = 27) at a single 250 mg/day dose over 8 weeks in healthy (not functionally limited) aged men, so any cross-population mapping is a tentative moderator hypothesis confounded by baseline status, dose (250 vs 500–1000 mg/day), duration (8 vs 12 weeks), and endpoint family (cardiovascular vs physical function/mitochondrial).
- A decisive falsifier would be a larger RCT in functionally limited older adults showing that resveratrol also attenuates training-induced gains on the same physical-function or mitochondrial endpoints, which would convert the split into a more uniform attenuation signal.
