# Alpha memo: resveratrol exercise cross-context evidence signal
**One-sentence alpha:** Rat data on resveratrol with exercise suggested plausible anti-inflammatory effects, while a small human RCT suggests those effects may not extend to vascular training responses in aged men, though the abstracts do not provide a complete numeric comparison.

**Receipt 1:** "The Impact of Resveratrol Supplementation on Inflammation Induced by Acute Exercise in Rats: Il6 Responses to Exercise" (2019) aimed to evaluate trans-resveratrol supplementation plus 12 weeks of exercise at 65% VO2 max on inflammation-related factors in 64 male Wistar rats; the abstract is truncated before reporting the inflammation-related factor results.

**Receipt 2:** "Resveratrol blunts the positive effects of exercise training in aged men; a double‐blind, randomized, placebo‐controlled training study" (2013) reports that 27 aged healthy inactive men (65 ± 1 years) were randomized to 8 weeks of 250 mg resveratrol or placebo alongside high-intensity exercise training three times per week, with the abstract truncated before the full numeric outcome is reported; the title states that resveratrol blunted the positive training effects, but the supplied excerpt does not give the complete endpoint, direction, or magnitude.

**Why this is surprising:** A rodent study framed resveratrol as plausibly anti-inflammatory during exercise, whereas the human RCT title claims the supplement blunted training benefits, a split the abstracts do not fully resolve.

**Caveats/falsifiers:**
- Receipt 1 is a 12-week rat study (n=64 Wistar, 65% VO2 max) and Receipt 2 is an 8-week human RCT (n=27, 250 mg resveratrol, aged men), so species, population, dose, route, duration, and sample size all differ; the moderator hypothesis is tentative and confounded by these axes, and no clinical, dosing, or supplementation recommendation follows from the two receipts.
- The 45% figure in Receipt 2 cannot be used because the supplied abstract is truncated and does not confirm the cardiovascular endpoint or direction; a decisive falsifier would be a larger, pre-registered human trial in aged men using the same 250 mg dose and exercise protocol that reports a significant additive or synergistic resveratrol effect on the same vascular or VO2max endpoint.
