Hormonal

Consuming whey protein, which has high leucine density, stimulates muscle protein synthesis more effectively than proteins with lower leucine content (such as wheat, soy, or casein) by triggering the mTORC1 signaling pathway.

Choose whey protein for your post-workout or high-priority meals because its high leucine content triggers muscle building signals more effectively than plant proteins or casein. Ensure you are also doing resistance training to maximize these benefits.

GoodSupportsHIGH confidence
Whey protein has been shown to increase anabolic signaling in skeletal muscle to a greater extent than proteins with lesser leucine densities, such as plant proteins.
