Animal protein plays a significant role in muscle growth due to its complete amino acid profile and high protein content. Sources like meat, fish, and dairy provide essential nutrients such as iron, zinc, and vitamin B12, which support growth and recovery. The bioavailability of these nutrients from animal sources is often higher than that from plant-based proteins. For those engaged in strength training or other high-intensity workouts, animal protein can enhance muscle protein synthesis, resulting in improved performance and recovery. Incorporating a variety of protein sources can provide a balanced approach to muscle development.
