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 which helps our body oxidize glucose and fat and increase the body’s lean muscle mass. It is responsible for performing many numerous functions in our body. Our body produces L-arginine with the helps of other enzymes, but at a fairly inefficient rate. So patients with a history of cardiovascular dysfunction or any other heart disease are likely to get benefited from L-Arginine supplementation. Supplements of L-arginine prevent platelet aggregation and lowers blood pressure. L-arginine when taken in safe amounts can benefit men having sterility problems. Many body-builders also use it as a supplement because it improves blood circulation and stimulates the release of nitric oxide which in turn dilates the blood vessel. High protein food like nuts, dairy products, meat, seafood and chocolate are rich in L-arginine.

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- Histidine is one of the twenty amino acids that are considered to be the building blocks of proteins. This proteinogenic amino acid is believed to be non-essential to adult humans, because at some point, after reaching a certain age, they begin to synthesize it. On the other hand, histidine is an essential amino acid to infants, and needs to be part of their regular diet. The amino acid L-Histidine is identified as a precursor for carnosine and histamine biosynthesis. In research studies it has been proven that histidine supplementation can cause an elevated excretion of zinc in rats, up to six times the normal amount. Humans sometimes use histidine supplementation to artificially raise histamine levels. L-Histidine is identified as playing a role with several trace elements, such as iron, molybdenum, manganese, zinc and copper.

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- 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-Lysine- Lysine is an essential alpha amino acid that needs to be ingested and cannot be synthesized by the human body. Sources of L-Lysine include meat, particularly red meat, lamb, poultry and pork, but also cheeses, like parmesan, some fish like cod and sardines and eggs. Several plants are rich in L-Lysine, soybean, lentil, spinach and buckwheat, but also buffalo gourd, watercress, locust bean and many other bean variants, including the common bean. L-Lysine is deemed vital for the overall production of protein, as a structural building block. It seems that L-Lysine also plays a prominent part in the absorption of calcium. Further properties include playing a role in the production of enzymes, hormones and antibodies, but also in the recovery from sports injuries and surgeries.

L-Methionine, an essential amino acid for the human body, acts as a building block for proteins. Since the body cannot produce it naturally, you need to take it through supplements and diet. This antioxidant is found in dairy products and meat and is essential for producing creatine. It is soluble in water and helps in breakdown of fats. You can also find L-Methionine in vegetables and fruits. Since it is a glycogenic amino acid, it helps in forming glycogen and D-glucose. On a daily basis, experts recommend only 13 mg of L-Methionine for adults. These supplements are not only effective in liver disease treatment but also beneficial for individuals who follow a vegetarian diet. You can enhance the quality of your skin, hair and nails by taking L-Methionine supplements.

L-Phenylalanine is a vital amino acid. It acts as a building block for various proteins produced in the body. It is found in most foods that contain protein, like poultry, beef, pork, milk, fish, yogurt, cheese, eggs, soy products, and certain nuts and seeds. It can assist in decreasing chronic pain linked with different health conditions by inducing nerve pathways in the brain which control pain. It can also help improve rigidity and is beneficial in conditions like walking disabilities, depression associated with Parkinson’s disease, and speech difficulties. Combination of L-Phenylalanine with ultraviolet radiation for people having vitiligo, a condition that is characterized by irregular depigmentation or white patches of skin, can lead to some darkening or repigmentation of whitened areas, especially on the face.

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 optimizes the utilization of animals that you consume in order to deposit protein to the muscles and aides in weight gain.

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 a common amino acid and a para-isomer of tyrosine. It is deemed organic because of the carbon atom present and it is nonessential to survival, but works as a building block of protein. It is also viewed as a precursor of dopamine, which has several effects, like offsetting fatigue, mental and physical, as well as increasing the impression of well being. When the amino acid phenylalanine is broken down, L-Tyrosine can be won completely naturally. Besides being a precursor of the aforementioned neurotransmitter dopamine, L-Tyrosine is also deemed a precursor to some adrenal hormones, namely epinephrine and norepinephrine. In body building circles this supplement is popular to offset fatigue after a hard training or competition, but also to raise mental alertness while working out.

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.

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 one of the three mass produced forms of whey protein. It is processed to completely remove fat and lactose, and is also low in bioactive compounds. Whey protein isolate is more then 90% protein by weight. While preparing supplements of whey protein isolate different flavors are also added. It is the ideal type of protein for sportsmen and bodybuilders to provide them with enough protein to fuel their muscles, and promote muscle growth. Whey protein isolate supplements can be taken by lactose intolerant people since they are free from lactose.
