# Alpha memo: resveratrol exercise protocol mismatch
**One-sentence alpha:** Adding resveratrol to exercise training in older adults may not travel as a clean positive signal; the same anchor can split by population, dose, and endpoint.

**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 71.8 ± 6.3 years with functional limitations) randomized participants to 12 weeks of exercise plus 0, 500, or 1000 mg/day resveratrol to evaluate safety and feasibility, with physical function and skeletal muscle mitochondrial function as outcomes; the abstract reports the design and intent-to-treat framework rather than an observed efficacy result.

**Receipt 2:** *Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men* (2013) — In 27 healthy inactive aged men (65 ± 1 years) randomized to 8 weeks of high-intensity exercise training with either 250 mg/day trans-resveratrol or placebo, exercise training led to a 45% (per the abstract) improvement in a cardiovascular health parameter that was reduced in the resveratrol arm, suggesting an attenuation rather than an enhancement of training-induced cardiovascular gains.

**Why this is surprising:** Receipt 1 made plausible the hypothesis that resveratrol would stack additively with exercise in older adults with functional limitations, while Receipt 2 updates that picture by showing the same combination can attenuate training-induced cardiovascular gains in aged men.

**Caveats/falsifiers:**
- Receipt 1 is a pilot feasibility RCT (N = 60, 12 weeks, two doses of 500/1000 mg/day in 71.8 ± 6.3-year-old functional-limited adults); Receipt 2 is a small efficacy RCT (N = 27, 8 weeks, 250 mg/day in 65 ± 1-year-old healthy inactive men), so the populations, doses, durations, and endpoints differ on multiple axes, and the moderator hypothesis (dose, population, endpoint family) is tentative and confounded.
- A decisive falsifier would be a sufficiently powered RCT in older adults with functional limitations using the same cardiovascular endpoint family and a dose-equivalent regimen, showing either additive benefit or null effects of resveratrol on top of exercise, which would overturn the Receipt 2 attenuation signal.
