Ingesting collagen after an exercise session does not further stimulate the synthesis of muscle connective tissue proteins.

This advice is based on randomized controlled trials (RCTs) conducted by Professor Stuart Phillips and his team (e.g., Medicine & Science in Sports & Exercise, 2023). This research demonstrates that while whey protein is effective at increasing contractile muscle protein synthesis, collagen does not provide a significant benefit for connective tissue protein synthesis following exercise. The notion that collagen is a superior source for building or repairing these specific tissues lacks robust clinical evidence in this precise context. It is common to see collagen promoted for recovery or joint health, but the data indicate that, compared to complete protein sources, it is less optimal for stimulating muscle repair processes. The creator highlights an important distinction here between supplement marketing and the actual biological response following training.
