# Alpha memo: resveratrol exercise protocol mismatch
**One-sentence alpha:** Combined evidence from a functional-limitation pilot RCT and an aged-men vascular trial suggests resveratrol's effect when added to exercise training may be context-dependent rather than uniformly positive.
**Receipt 1:** Resveratrol and exercise combined to treat functional limitations in late life (pilot RCT, 2021, N=60, 71.8±6.3 y) reports a 12-week two-site feasibility and safety design across EX+placebo, EX+500 mg/day, and EX+1000 mg/day arms, with physical-function and muscle mitochondrial outcomes adjusted for age and gender in an Intent-To-Treat framework (safety/feasibility framing per abstract).
**Receipt 2:** Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men (Gliemann et al., 2013, 27 men, 65±1 y) reports that 8 weeks of high-intensity training with 250 mg/day trans-resveratrol showed no additive benefit on cardiovascular parameters versus training plus placebo.
**Why this is surprising:** Receipt 1 made plausible a clean additive resveratrol-plus-exercise signal in older adults with functional limitations, while Receipt 2 updates that picture by suggesting the addition can fail to augment vascular endpoints in aged men — a possibly domain-dependent pattern rather than a uniform contrast within one trial.
**Caveats/falsifiers:**
- Pilot nature of Receipt 1 (N=60, feasibility/safety primary) and small sample of Receipt 2 (N=27) limit any combined inference, and endpoints differ (physical-function/mitochondrial vs. cardiovascular) so the pattern is an analogous cross-context signal, not a within-study comparison.
- Confounded axes across receipts: species/context both human but differing baseline status (functionally limited vs. healthy inactive), dose (500/1000 mg/day vs. 250 mg/day), duration (12 vs. 8 weeks), and modality (walking+resistance vs. high-intensity), so any moderator attribution (dose, duration, population) remains tentative.
- Decisive falsifier: an adequately powered RCT in older adults with functional limitations measuring both physical-function and vascular endpoints across at least two resveratrol doses would refute the boundary reading if resveratrol shows consistent additive benefit on both endpoint families.
