Amino Acids are the building blocks of proteins and proteins are necessary for the growth, repair as well as maintenance of all our vital organs. Amino acids that the body derives from our daily diet are called as ‘essential amino acids’ while ‘non essential amino acids’ refer to those which the body can produce from other sources. Non essential amino acids can either be obtained from essential amino acids or even normal breakdown of proteins. There are 20 amino acids and each one of them has a unique role to play, irrespective of whether it is essential or non essential. Thus, vegetarians are usually recommended to take amino acid supplements, since plants lack one or more essential amino acids.

L-Arginine is an amino acid that performs several functions in the human body. L-Arginine not only helps in getting rid of the ammonia but also aids the formation of nitric oxide, a compound responsible for relaxation of blood vessels. This amino acid is also involved in the formation of protein in human body. Besides stimulating the release of prolactin and growth hormones, L-Arginine can help in the treatment of heart diseases as it increases blood flow and improves the function of the blood vessels. It is effective for treating erectile dysfunction and heals wounds effectively. L-Arginine is produced in the liver as well as the kidney. Food items which include this acid are animal proteins like meat, fish, poultry and plants. L-Arginine supplements become essential when the supply of arginine depletes because of infections and severe burns.

L-Glutamine- Glutamine is an amino acid which is responsible for a multitude of biochemical functions in humans. L-Glutamine is generally found in dietary sources such as chicken, beef, eggs, milk and dairy products, fish, spinach, wheat, parsley, cabbages, beans and beets. Glutamine is apparently the most common amino acid occurring naturally, furthermore this non essential amino acid is one of just a few, which are able to directly cross the blood brain barrier. In the human body, L-Glutamine is found in the skeletal muscles, but also in the blood. Besides the vital biological functions, such as fuel for brain, blocking cortisol induced protein catabolism, immune function assistance, protein synthesis and in DNA synthesis, L-Glutamine is used as a supplement for ailing and injured, improving recovery, but also as muscle growth agent in body building and athletic circles.

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- Leucine is an essential amino acid that does not synthesize in humans and so must be ingested. It slows the degradation of muscle tissue and is used in the formation of sterols.

L-Valine is an amino acid in combination with L-Leucine and L-Isoleucine. These amino acids maintain everyday life and offer maximum support. L-Valine is acquired from vegetable and animal protein. L-Valine regulates the immune system and is involved in the protein synthesis and glucose metabolism. L-Valine is effective in muscle growth as well as tissue repair. L-Valine is a part of the muscle metabolism and is also effective in the nitrogen balance in the body. L-Valine is found in the muscles in high concentration, but this cannot be done on its own in the body and has to be acquired through dietary or food supplements. L-Valine has stimulating effect and maintains the nitrogen in the body. It is effective for repair as well as growth of tissues and for muscle metabolism. Adhering to the label directions is highly recommended. This is normally safe and has no side effect until now. However, for the dietary supplement consulting the physician before use is the best.

Stevia, the genus Stevia Rebaudiana, is specie of shrubs indigenous to Paraguay. Not only is it a natural and sweet alternative to artificial sweetening agents like aspartame but also has almost no calories. Moreover, use of Stevia supplements has shown to boost moods, energy levels as well as mental alertness. The extract derived from the leaves of Stevia is known as Stevioside and is used in supplements in the form of green or white powder or even brown liquid. It is advisable to use the Stevia supplements in the green powder form since it contains various nutrients. Besides this, it also offers several benefits like improving the immune system. Thus, it is very valuable as a dietary supplement to bodybuilders and dieters. It is ideal for those suffering from diabetes and hyperglycemia.
