Dr. Luc van Loon is a renowned figure in the realm of exercise science, particularly celebrated for his deep understanding of protein metabolism, resistance training, and the nuanced role of collagen supplements in sports nutrition. Our conversation is an in-depth discussion on optimal protein intake & distribution strategies for stimulating muscle protein synthesis with delightful detours into insightful discussion of un ique topics like the timing of cold-water immersion.
