Beta-Alanine- Non-essential amino acid beta-alanine is the only naturally occurring beta-amino acid. It is classified as a non-proteinogenic amino acid as it is not involved in the process of protein synthesis. Beta-alanine are obtained by ingesting dipeptides (carnosine, anserine and balenine) which are found in protein rich foods like chicken, beef, pork and fish. Most of the beta-alanine we ingest is through didpeptide carnosine since the other two are not found in our typical diets. However apart from the diet, beta-alanine is also synthesized in the liver from the catabolism of pyrimidine nucleotides. Beta-alanine is beneficial for those trying to gain muscle mass and increase strength. It is also useful for athletes who are looking for muscle strength, power and endurance. Since it is so useful for muscle development, several supplements used by athletes have beta alanine as a primary component.

Citrulline Malate is a combination of citrulline and malate. It is showing strong evidence of improving muscle weakness. This is beneficial for those involved in bodybuilding as a muscle strengthener.

L-Glutamine- Found in plasma and muscles of the human body, L-Glutamine is an essential amino acid. In the skeletal muscle cells, more than 60% of free floating amino acid is made of L-Glutamine. It acts as the primary donor of nitrogen and moves in the body wherever required. This amino acid has been considered useful in reducing physical stress. During surgery or heavy exercise regime the human body needs it for maintaining the level of glutamine in muscles and blood. It is also essential for maintenance of immune system and prevention of intestinal stress. Glutamine supplements can help in restoring L-Glutamine levels during stress. L-Glutamine supplements are relatively less expensive and help in minimizing the breakdown of muscles. It also improves the metabolism of protein in the human body and ensures a positive balance of nitrogen.

L-Isoleucine is an essential alpha-amino acid that is considered both, a ketogenic and a glucogenic amino acid. Since that L-Isoleucine is an essential amino acid, it cannot be synthesized by the body, therefore it needs to be ingested. The primary source of L-Isoleucine is as a component of proteins. It has become a prominent component of nutritional supplements, mostly with the body building and similar athletic communities, where it is believed that L-Isoleucine has the capability to increase endurance, but also to repair muscle tissue. It has been observed that L-Isoleucine ingestion allows power athletes to recover easier from very tough trainings and exhausting activities. This branched chain amino acid is one of the three main BCAA in the body, the other ones being valine and leucine.

L-Leucine is useful in conjunction with L-Valine and L-Isoleucine as an amino acid supplement. L-Leucine is an amino acid that a body cannot produce on its own. It is expected to be received externally from food sources such as brown rice and nuts or even through some of the dietary supplementation. L-Leucine is showing numerous advantages in the athletic qualities. Within six week of training with L-Leucine in association, a person is able to maximize the aerobic power. In the six weeks the strength and power in the upper body increases. However, research and studies is limited carried on the athletic performance. L-Leucine incorporated into the muscle protein in continuation with two weeks exercise regime will give adequate resistance and the muscle protein synthesis will certainly show an increase. L-Leucine is a preservative of the muscles, but is as well a supplement that enhances the capabilities of muscle building owing to the enhanced protein synthesis rate.

L-Valine- L-Valine is one the three Branched Chain Amino Acids (BCAAs). The other two BCAAs are L-isoleuine and L-leucine. L-Valine is required by the body for the proper function of the nervous system and the brain. L-Valine is not processed by the liver; instead, it goes directly to the muscles. It helps enhance muscle growth and help it to recover faster after an intense workout. It also helps in muscle tissue repair and maintains the proper amount of nitrogen in the body. It can also be used as an energy source that gives energy and strength to the muscles. L-Valine has other benefits; it is also helpful in liver regeneration, improvement of insomnia and nervousness, and is an effective appetite suppressant.
