Promisingcounts toward this tier
15 g gelatin before exercise doubled serum PINP (a collagen-synthesis marker) and improved engineered-ligament mechanics ex vivo.
- Population
- Healthy young men, crossover design
- Intervention
- 5 or 15 g gelatin in a drink carrying 48 mg vitamin C, taken 1 h before 6 min of rope skipping
- Comparator
- Placebo
- Limitations
- Very small crossover; surrogate biomarker rather than clinical outcome. NIH-funded, no manufacturer.
