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- The second of three branched chain amino acids it is important in blood sugar regulation and producing hemoglobin. After exercise, it is responsible for muscle recovery and important in the metabolism to produce energy.

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 is the third branched chain amino acid and is required for muscle metabolism, repairs and regenerates tissue, and maintains the body's nitrogen level. It also is used as a muscle energy source and preserves the use of glucose.

Taurine is an organic acid which is one of the primary ingredients of bile, found in the lower intestine as well as in small amounts in the tissues. Taurine is an important element as it is required for fat digestion through the emulsification of dietary fats. It is also needed for the absorption of fat-soluble vitamins as well as the control of cholesterol serum levels. Taurine is also needed for the proper use of sodium, calcium and potassium in the body. Cell membrane integrity is also maintained with the help of taurine. Apart from these, research has shown that taurine can be very helpful in managing anxiety, hyperactivity, reduced brain functioning etc. Studies have also revealed that along with zinc, taurine is essential for proper vision. In case of a taurine deficiency there is vision impairment along with problems with fat metabolism, however since the body can synthesize the minimum amount of taurine required, this is a rarity.
