Muscle & Fitness lists casein protein powder, nitric oxide boosters, ZMA, carnitine, beta-ecdysterone and high molecular-weight carbs as additional supplements for bodybuilding. As stated by Bodybuilding.com, every supplement does not work the same for every person because of the unique nature of each human body. However, creatine, beta-alanine, whey protein, BCAA's and glutamine appear to provide the best results across the board.
Bodybuilding.com states that creatine occurs naturally within muscle cells and is present primarily around skeletal muscle tissue. Benefits of creatine supplementation include the promotion of lean body mass, increased muscle cell volume and faster post-workout recovery. Creatine helps build muscle mass rapidly. Beta-alanine is an amino acid commonly found in high-protein foods such as poultry, which works in synergy with creatine. Benefits of beta-alanine include increased endurance and improved force output.
Whey protein is easily consumed in daily protein shakes, notes Bodybuilding.com. This supplement is easily digested, improves muscle repair, and acts as a natural appetite suppressant. BCAA's include three amino acids found in the body: leucine, isoleucine, and valine. These amino acids stimulate protein synthesis. This supplement helps muscles recover and reduces pain from muscle fatigue. Glutamine benefits include preservation of muscle tissue, improved immune system and increased plasma growth hormone.
