Whey protein is beneficial for muscle building due to leucine, and individuals experiencing acne might consider reducing their whey protein intake as an experiment.

“So through that lens, I can confidently answer the question by saying that a quality whey protein would be a better choice for a protein as compared to bone broth or a collagen protein, which have relatively low amounts of leucine. And if you look at their essential amino acid profile, just sort of across the board, not just focusing on leucine, and compare that to whey protein, we would easily say that whey protein is the superior form of protein, again, both based on its bioavailability and its amino acid composition.”
