# Alpha memo: resveratrol exercise protocol mismatch
**One-sentence alpha:** Adding resveratrol to exercise may be safe and feasible in older adults with functional limitations, but may also blunt exercise-induced cardiovascular gains in healthy aged men.
**Receipt 1:** Resveratrol and exercise combined to treat functional limitations in late life (2021) — a three-arm pilot RCT (N = 60, ~71.8 years) suggests that 12 weeks of exercise plus 500 or 1000 mg/day resveratrol is feasible and safe, with physical-function and skeletal-muscle mitochondrial outcomes assessed.
**Receipt 2:** Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men (2013) — in 27 healthy inactive aged men (~65 years), 8 weeks of high-intensity training with 250 mg/day trans-resveratrol may interfere with exercise-induced MAP reductions relative to placebo.
**Why this is surprising:** Receipt 1 framed resveratrol as a tolerable adjunct during exercise in older adults, while Receipt 2 suggests the same anchor can move in the opposite direction on cardiovascular endpoints under similar exercise conditions.
**Caveats/falsifiers:**
- Receipt 1 is a pilot protocol-feasibility signal (N = 60, two doses 500/1000 mg), not an efficacy result, and uses a different population (functional limitations) than Receipt 2 (healthy aged men).
- Receipt 2 uses a lower dose (250 mg) and a healthier baseline, and the moderator hypothesis (dose, baseline status, population, duration) is tentative and confounded by multiple axes.
- A decisive falsifier would be an adequately powered RCT in the same population and dose range showing additive, not blunted, cardiovascular improvement when resveratrol is combined with exercise.
