# Alpha memo: resveratrol exercise protocol mismatch
**One-sentence alpha:** Two small trials in older adults suggest resveratrol's apparent synergy with exercise on physical function may not extend to cardiovascular endpoints, hinting at a domain-specific rather than uniform interaction.

**Receipt 1:** *Resveratrol and exercise combined to treat functional limitations in late life: A pilot randomized controlled trial* (2021, N = 60, ages ~71.8) — a three-arm pilot RCT testing 12 weeks of exercise + placebo vs. exercise + 500 mg/day vs. exercise + 1000 mg/day resveratrol in older adults with functional limitations; primary aims were safety/feasibility, with physical-function and skeletal-muscle mitochondrial outcomes as secondary endpoints.

**Receipt 2:** *Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men* (2013, N = 27, age 65 ± 1) — 8 weeks of high-intensity training + 250 mg/day trans-resveratrol vs. placebo; the abstract framing is that resveratrol supplementation was hypothesized to enhance training-induced cardiovascular gains, while the paper title reports the opposite direction on cardiovascular endpoints in aged men.

**Why this is surprising:** Receipt 1 made plausible a broadly additive or neutral resveratrol + exercise signal on functional endpoints; Receipt 2 updates that to a direction where resveratrol may attenuate training-induced cardiovascular gains, suggesting the interaction is not uniformly positive and may depend on the endpoint domain.

**Caveats/falsifiers:**
- Receipt 1 is a small pilot (N = 60) in community-dwelling adults with functional limitations at two resveratrol doses (500/1000 mg/day) over 12 weeks; Receipt 2 is also small (N = 27), uses a lower dose (250 mg/day), shorter duration (8 weeks), and a healthier inactive but non-limited baseline — the moderator (dose, duration, baseline status, or endpoint family) behind the contrast is confounded and cannot be isolated from these receipts.
- Decisive falsifier: a randomized trial in older adults that holds dose, duration, and training modality constant and measures both functional and cardiovascular endpoints in the same participants; if resveratrol shows additive gains on vascular measures here, the Receipt 2 blunting effect would not generalize beyond its specific context.
