Published in American Journal of Clinical Nutrition
Methodology
Randomized double-blind crossover trial giving vitamin C-enriched gelatin before short jump-rope loading, with blood markers of collagen synthesis and an engineered ligament model.
Key Findings
Gelatin plus vitamin C doubled amino-terminal propeptide of collagen I in blood and improved mechanics of engineered ligaments.
Conclusions
Gelatin with vitamin C taken an hour before loading increases collagen synthesis relevant to ligament and tendon tissue.
Limitations
Small sample; surrogate blood and in vitro endpoints rather than clinical ligament outcomes.
Supplements Studied
