Aspartic Acid is a non-essential amino acid which is bountiful in plant proteins. It can also be produced in the human body from oxaloacetic acid. Some biochemicals that are synthesized from aspartic acid include asparagine, arginine, lysine, methionine, threonine, isoleucine, and a number of nucleotides. Apartic acid is used for stamina, the brain and overall health as it helps the liver by removing excess harmful ammonia and other toxins from the bloodstream. If ammonia enters your circulatory system it can be harm your central nervous system and cause neural and brain disorders. Aspartic acid helps to keep the mind sharp by increasing concentrations of NADH in the brain.

L-Alanine is considered as a supplementary amino acid. The presence of carbon atom in its composition leads to the formation of L alanine, which is organic in nature. The best sources of L-alanine would be fish, beef, pork and poultry. The various protein sources which are animal based would consist of a good amount of l-alanine. The alanine levels increases with the contraction of muscles in the body. L- alanine is used by the body to build proteins. It also helps in the transfer of nitrogen from the tissues in our body. It helps to draw blood sugar and hence acts as a good energy resource producer. This would be best suited for those who want a reduction in extra body fat.

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-Cysteine can be used to help with skin health. It also has been known to stop hair loss & aid normal hair growth. In some studies L-Cysteine has shown to Help the body's natural detoxification process and Enhance absorption of iron. L-Cysteine also Supports the production of red & white blood cells.

L-Glutamine is an amino acid that occurs most abundantly in the body by being released from muscles under stress. Aside from increasing the immune system’s efficiency to fight diseases, it also takes care of the normal functioning of the brain and the digestive system through the removal of excess ammonia in the body. A number of factors, such as stress, infections, injuries and surgery affect the levels of glutamine in the system, showing that the healing process is under way. Glutamine supplements may be used by regular exercisers to help in the recovery of muscular fitness after a workout. Glutamine, however, is known to be linked with infections of the intestine and users are advised to seek advice from professionals before ingesting this amino acid.

L-Glycine- Glycine is an organic compound and one of the 20 amino acids deemed as building blocks for proteins. This proteinogenic amino acid is not only the smallest but also the only amino acid of the group that is not chiral, which means there is no enantiomer of glycine. With the prominent exception of collagen, which thirty five percent are glycine, most proteins contain only small amounts of it. As a solid, glycine is sweet tasting, crystalline and has no color. Despite being non-essential, because it can be biosynthesized from the amino acid serine, glycine has several important physiological functions, besides being a precursor to proteins. It is a biosynthetic intermediate of purines and the D-Aminolevulinic acid and it is an inhibitory neurotransmitter found in the central nervous system.

L-Histidine is an amino acid that is essential to the body, but is not produced by the body. It is made available through various food sources. Histidine helps in the manufacture and repair of tissues in the body, and in the formation of red and white blood cells which help in the treatment of anemia. It is also used for the production of gastric juices by the stomach. A deficiency in Histidine can lead to cataract and rheumatoid arthritis. Besides this, it is also a well known component of the skin that protects it by absorbing the ultra violet rays of the sun. A variety of foods such as meat, legumes, seafood, nuts, poultry and dairy products are providers of the required amounts of L-Histidine.

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-Lysine is an essential amino acid obtainable from daily food sources we consume. It has many medicinal properties which benefit us in our daily lives. While it is mainly used in the treatment of herpes, it also helps us become stronger by building our muscle tissues. It helps us to recover form injuries and surgeries besides absorbing calcium for building healthy bones. It also regulates the production of antibodies, enzymes and hormones which are required for healthy immunity level. L-lysine when consumed in high doses can lead to serious conditions. Although L-lysine is important for good health, we never really realize we are consuming it. Deficiency of L-lysine causes lethargy, amnesia, enzyme disorders, reproductive problems and hair loss. Generally, L-lysine is present in all vegetarian and non-vegetarian foods. Fish and cereals have higher amount of L-lysine in them.

L-Methionine- One of the most significant amino acids there is for the breaking down of fats. It is water-soluble and is known for deactivating free radicals. Recognized as being a leading antioxidant.

L-Phenylalanine- The human body needs L-Phenylalanine for survival as it is an essential amino acid. It is found in food items that are rich in protein such as eggs, meat, dairy products, beans and fish. Since the body cannot produce L-Phenylalanine from other chemicals, you need to increase the intake of protein for fulfilling the nutritional needs. L-Phenylalanine is one of the chemical forms of Phenylalanine, an amino acid. It helps in building up of several proteins produced by human body. L-Phenylalanine supplements act as an appetite suppressant as it initiates the release of cholecystokinin, an intestinal hormone. Once this hormone enters the stomach, it signals your brain that you are not hungry anymore. According to experts, you should not take more than 500-1000 mg of L-Phenylalanine per day.

L-Proline is a proteinogenic alpha amino acid, one of only twenty amino acids that are DNA encoded for the forming of protein. It is not deemed essential because humans are able to synthesize it from the amino acid L-Glutamate. This unique member of the twenty protein building block amino acids is the only one of the group that is distinct as belonging to the secondary alpha amino group. L-Proline plays a role in the synthesis of collagen. Collagen is undeniably the most common protein in mammals, being found in skin, tendons, joints, ligaments, vasculature and bones. It is deemed good for the health of joints, when taken as a supplement. Low protein diets, vegetarian and vegan diets as well as malnutrition lead to diminished L-Proline levels.

L-Serine- Serine is an organic compound and a proteinogenic amino acid that is considered a building block for the creation of proteins. This member of the hydroxyl group and a polar amino acid is not essential and therefore it is not necessary to ingest it by means of diet. L-Serine can be synthesized from metabolites such as glycine. L-Serine plays a role in the biosynthesis of pyrimidines and purines, furthermore it is a precursor to many metabolites like sphingolipids and to amino acids like cysteine and glycine. It is also involved in catalytic functions of several enzymes. L-Serine can be transformed into D-Serine by the serine racemase, which functions as a neuronal signal and NMDA receptor activator in the brain, a vital glutamate receptor responsible for memory functions and synaptic plasticity.

L-Threonine is an essential alpha amino acid, classified as polar. There are three proteinogenic amino acids that have an alcohol group, besides threonine there are tyrosine and serine. Like many other amino acids that are not synthesized in humans, threonine needs to be ingested through protein food sources that contain it, namely meat, poultry, cottage cheese, fish, sesame seeds and others. When ingested, threonine goes either through the threonine dehydrogenase and becomes pyruvate or, as in humans, it can be converted by the enzyme serine dehydratase to alpha ketobutyrate and continue towards succinyl-CoA. Threonine is also supposed to assist the protein balance by maintaining normal growth, but in addition to that, it seems to support the immune system, the central nervous system, the liver and the cardiovascular system.

L-Tryptophan- Tryptophan is an essential amino acid as well as within the group of only twenty standard amino acids that are required by the human diet. It is one of the building blocks required for protein biosynthesis. It is also viewed as a precursor to serotonin and thereby also melatonin, niacin and also auxin. Interestingly enough, lactose intolerance and fructose malabsorption have the side effect that tryptophan is only improperly absorbed in the intestines which leads to diminished levels of it in the system. Dietary sources of tryptophan are plentiful, it can be found in red meat, poultry, fish, milk, milk products, peanuts, mangoes, dates, chocolate and oats, among others. As a dietary supplement tryptophan has found applications as a safe sleeping aid and also as a calming agent.

L-Tyrosine is an amino acid that is nonessential. It is synthesized from the body from phenylalanine which is also an amino acid. L-Tyrosine has the power to have an effect on the neurotransmitters and this affects various health conditions including depression, mood disorders and Parkinson’s disease. Many such studies have proved that L-Tyrosine helps people having depression. It acts as a precursor and eases the effects of psychosocial, environmental and physical stress. L-Tyrosine turns into melanin by the skin cells and the dark pigment prevents the ultraviolet light from affecting. The thyroid hormones playing a significant role in the process of the body also contain tyrosine. L-Tyrosine is commonly found in all the dairy products, fish, oats, wheat, meat and also in all other protein containing foods. This is also found to be beneficial for people trying to withdraw alcohol. L-Tyrosine has not exhibited severe side effects, yet taking it should be recommended by doctors.

L-Valine, an essential amino acid, promotes the smooth functioning of the body. It is derived from animal and vegetable proteins like seafood, poultry, meat, cottage cheese, sesame seeds, dry whole lentils and roasted peanuts. It regulates the immune system, assists protein synthesis and glucose metabolism. It also promotes growth of muscles and repair of tissues that get damaged due to stress, disease, surgery or injury. It maintains the body’s nitrogen level and energizes the muscles. L-Valine helps detoxify the body against ammonia and prevents muscle wasting in diabetics. It assists in correcting drug addiction related amino acid deficiencies, gallbladder and liver diseases and is linked with treating neurological conditions and brain damage due to alcohol intake. One should consult a physician before consuming the supplement.

Whey Protein Concentrate is the concentrated form of whey protein, which contains sixty five percent beta-lactoglobulin , twenty five percent alpha-lactalbumin (~25%), eight percent serum albuminand and two percent immunoglobulins. Whey protein concentrate contains low level of fats and cholesterol, and a high level of carbohydrates and bioactive compounds. It is twenty nine to eighty nine percent proteins by weight. Whey protein concentrate is mostly used by athletes and in general medical application because it provides proteins and low quantities fats, cholesterol and carbohydrates. It is not the favorite supplement for body builders because they generally use whey protein isolate, which contains more than ninety percent protein by weight.

Whey Protein Isolate is a pure high quality protein made from cow's milk. It is a naturally complete protein containing all of the essential amino acids required by the body daily. It is a rich source of branched chain amino acids which metabolize directly into muscle tissue and are the first ones used during periods of exercise and resistance training. It is an excellent source of Lucien which plays a key role in promoting muscle growth. Whey protein also helps stabilize blood glucose levels by slowing the absorption of glucose into the bloodstream.
