Adequate protein intake is an important concern for many athletes who are undergoing strength-training programs. Many athletes choose to take a protein supplement, such as whey protein, in order to help them build lean muscle mass more efficiently. But the benefit of very high levels of dietary protein in resistance training remains questionable. This paper examines the effectiveness of whey protein, and other forms of protein supplements, in helping athletes augment their muscle mass. A comparison is also made between whey and other forms of protein with respect to efficacy and other potential benefits besides muscle gain. Review of the current literature seems to indicate that protein supplementation can induce significant gains in muscle mass, and that whey protein can provide these gains but may lack other benefits for overall health. Nevertheless, protein supplementation is not essential if adequate protein intake can be achieved from dietary sources.
