Beta-Alanine, or rather beta-alanine and 3-aminopropanoic acid, is also considered the only naturally occurring beta amino acid, despite being part of larger bioactive molecules like beta-peptides. Beta-alanine is a rate limiting precursor to the dipeptide carnosine, which means that carnosine levels depend on the available amounts of beta-alanine. Carnosine is abundant in brain tissues and muscles. It has been observed that supplementation with Beta Alanine in fact does increase the levels of carnosine, which resulted in athletes experiencing less fatigue and allowing them to boost the amount of muscular work, i.e. the training that can be done. In clinical trials conducted over ten weeks with supplementing Beta Alanine to test subjects, intramuscular carnosine levels were measured at eighty per cent higher levels than before the test.

Citrulline Malate is not only effective in boosting endurance but it also provides energy to the body for quick recovery. This ingredient is a mix of citrulline, involved in urea cycle and a malate which is a tricarboxylic acid cycle intermediate. Citrulline Malate is said to enhance the performance of muscles in patients who suffer from asthenia. Generally prescribed for antiasthenic treatments, it is also effective in controlling sensation of fatigue. Citrulline Malate is a compound which consists of citrulline, an amino acid found in water melons. According to European clinicians, it not only enhances the level of energy but also helps in increasing the feeling of well being in the human body. Citrulline Malate is sold as a dietary supplement for enhancing the performance of athletes. As a supplement, it is a salt form of the amino acid.

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 one of the amino acids besides the other two, L-Valine and L-Leucine. These are found in all the forms of life as proteins. They are as well obtainable in the diet through vegetable and animal sources. L-Isoleucine is good to regulated blood sugar as well the energy levels. It is also important in the synthesis of hemoglobulin and thereby increases endurance. L-Isolecuine gets metabolized in the tissues of the muscles and the opulent L-Isolecuine sources are almonds, cashews and soy protein. Hence, this is prominent among athletes and is taken in combination with the other two amino acids, L-Leucine and L-Valine. L-Isoleucine is required for the formation of hemoglobin and also regulates as well as stabilizes the energy levels. The other food sources of L-Isoleucine are eggs, meat, fish, rye, chickpeas, chicken, liver and lentils. People suffering from physical and mental disorders are usually deficient in L-Isoleucine. These amino acids are required for the synthesis of enzymes, structural protein and for hormones.

L-Leucine is an essential amino acid that works together with isoleucine and valine, forming the three branched chain amino acids (BCAA). Leucine is easily converted by to body to glucose, helping to regulate and maintain the blood sugar level. Leucine promotes muscle recovery, muscle repair and provides the body with energy. It also helps in burning fat that are least responsive to exercise and dieting. Leucine helps in toning the body and the muscles. Leucine prevents muscle loss by breaking down and converting to glucose, this prevents the body from breaking down muscle tissues to create energy, particularly during intense workouts and heavy weight lifting.

L-Valine is an amino acid with stimulant activities. It not only helps in tissue repair but also promotes muscle growth. It is one of the three branched amino acids that are formulated for providing support to the human body for normal functioning. Derived from animal and vegetable protein, L-Valine is not only involved in the synthesis of protein and metabolism of glucose but it also regulates the immune system. L-Valine is also effective in maintaining the exercise recovery time and the balance of nitrogen in the body. Since the human body doesn’t produce this amino acid naturally, you need to acquire it through dietary supplements and food items. When taking L-Valine supplements, you must follow strict directions from the physician. Even though it doesn’t have any side effects, it helps to consult the physician before its usage.
