Different types of protein sources vary in their effectiveness for supporting muscle growth. Animal-derived proteins, such as whey and casein, are considered high-quality proteins because they provide all essential amino acids required for muscle repair and growth. Plant-based proteins like peas, soy, and quinoa are also beneficial but may lack certain essential amino acids. Combining different plant sources can enhance their amino acid profile. Furthermore, the timing and amount of protein consumption post-exercise can significantly influence muscle synthesis and recovery, regardless of the source.
