Most bodybuilders augment their protein by taking whey protein supplements. Whey protein originates from the process of converting milk into cheese. Various studies, according to MedicalOnline.com.au, show that whey protein has the highest amount of branched amino acids responsible for bodybuilding and muscle retention.
Protein can be obtained naturally in regular foods such as dairy products, soy, meat and eggs. However, the quality from these food products cannot compare to whey protein, which is also easy to add to a meal or snack. Although there are other protein supplements available, whey protein, according to WebMD, produces the best performance compared to other supplements.
