# Alpha memo: resveratrol exercise context boundary
**One-sentence alpha:** Pilot RCT Receipt 1 made resveratrol + exercise feasible and safe in older adults with functional limitations, while Receipt 2 suggests the same adjunct may blunt an oxidised LDL–related vascular measure (~45%) from training in aged men.
**Receipt 1:** *Resveratrol and exercise combined to treat functional limitations in late life: A pilot randomized controlled trial* — a three-arm, two-site pilot RCT (N = 60, mean age ~71.8) evaluating 12 weeks of exercise plus 0/500/1000 mg/day resveratrol, assessed for safety, feasibility, and adherence in community-dwelling older adults with functional limitations.
**Receipt 2:** *Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men* — 27 healthy inactive aged men (~65 yrs) randomized to 8 weeks of high-intensity training plus 250 mg/day trans-resveratrol or placebo, where the abstract reports that exercise-induced gains were not preserved on an oxidised LDL–related measure, an effect described by the authors as a ~45% reduction (relative to the training+placebo response).
**Why this is surprising:** Receipt 1 made plausible that 500–1000 mg/day resveratrol can be layered onto exercise safely in older adults, yet Receipt 2 updates that an oxidised LDL–related vascular benefit from training may be attenuated when 250 mg/day resveratrol is added in aged men.
**Caveats/falsifiers:**
- Receipt 1 is a small pilot (N = 60) designed for safety/feasibility and adherence, not efficacy; Receipt 1 did not establish adjunct efficacy, and its primary endpoints (physical-function battery, muscle mitochondrial outcomes) differ from Receipt 2's oxidised LDL–related measure.
- Receipt 2 is itself small (N = 27) over 8 weeks at 250 mg/day and only reports ~45% blunting of an oxidised LDL–related training effect; a decisive falsifier would be an adequately powered RCT in older adults using Receipt 1's doses/duration that fails to show attenuation of vascular endpoints, or one that confirms it, isolating dose, duration, baseline training status, and endpoint family.
