- Research from 2022 published in the International Journal of Sport Nutrition and Exercise Metabolism directly compared whey protein and leucine-matched collagen peptides during resistance training. Despite equivalent leucine content, whey produced superior muscle thickness gains.
- A 2022 study in the American Journal of Clinical Nutrition examined muscle protein synthesis in older women. Whey stimulated synthesis significantly in both resting and exercising conditions. Collagen stimulated synthesis only with exercise, and to a lesser degree.
- These studies establish clear hierarchies for muscle building purposes. Complete proteins outperform collagen regardless of leucine matching.
