# Alpha memo: resveratrol exercise training cross-context signal
**One-sentence alpha:** Mouse data suggest resveratrol can dampen high-intensity exercise-induced intestinal inflammation/ferroptosis signaling, but a small human trial (Gliemann et al., 2013) suggests resveratrol may blunt training-induced gains in cardiovascular endpoints, indicating a context-dependent rather than uniformly protective split.

**Receipt 1:** Lin et al. (Turk J Med Sci, 2023) — In mice, 28 days of resveratrol (15 mg/kg/day) alongside a swimming high-intensity exercise protocol attenuated intestinal inflammation and ferroptosis-related markers (Nrf2/FTH1/GPX4 pathway).

**Receipt 2:** Gliemann et al. (J Physiol, 2013) — In 27 healthy physically inactive aged men (~65 y), 8 weeks of 250 mg/day trans-resveratrol with high-intensity exercise training resulted in VO2max gain ~45% lower than placebo + training (i.e., resveratrol blunted the training-induced cardiovascular improvement); the abstract frames this as resveratrol blunting the positive effects of exercise training on cardiovascular health.

**Why this is surprising:** Receipt 1 made resveratrol plausibly a co-administered protective adjunct in a high-intensity exercise context; Receipt 2 updates that by showing the same anchor can move in the opposite direction in humans on cardiovascular endpoints, splitting the expected uniform benefit.

**Caveats/falsifiers:**
- Receipt 1 is a murine mechanistic/intestinal study (15 mg/kg, 28 d) and Receipt 2 is a small human cardiovascular trial in aged men (n≈14 vs 13, 250 mg, 8 wk); species, tissue, endpoint family, dose, duration, and baseline status all differ, so the moderator hypothesis is tentative and confounded.
- A decisive falsifier would be a sufficiently powered human RCT in a comparable population replicating the Gliemann VO2max/cardiovascular blunting while measuring intestinal inflammation and Nrf2/FTH1/GPX4 markers in the same participants.
