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-Aspartic Acid is a natural amino acid and is mainly used as medicine. This can be employed as chemic and biologic reagent, organic synthesized intermediate and culture medium. This is useful as medicine for heart disease, accelerant for liver function and also is a significant component for transfusion of amino acid. L-Aspartic acid is a crystalline powder that comes odorless and has acid taste. This is lightly soluble in water but is perfectly soluble in acid. However, it is insoluble in ether or ethanol. L-Aspartic acid is mixed in nutritional supplements and cool drinks. This is also useful as medicine or fatigue refresher. This can be employed as biochemical reagent and as an important raw material for sweetener as well as for pharmaceuticals. L-Aspartic acid is an important ingredient in the pharmaceutical industry especially in the manufacturing processes. L-Aspartic acid is employed in the form of salt for mineral supplementation.

L-Cysteine- If two cysteine molecules are bound together by a disulfide structural unit, the amino acid dimer L-Cystine is formed. It is deemed a vital component of proteins, where formations of the disulfide bonds are made between and within protein molecules. It seems that thereby L-Cystine is determining to a significant amount the three dimensional structure of a prominent number of proteins. For instance, it has been determined that human hair contains about five percent of cystine. In case that the non-essential alpha amino acid cysteine is required by the body, the disulfide link is apparently readily reduced. While cysteine can be derived from protein rich sources such as meat, poultry and dairy products, L-Cystine, although present in these, is most abundantly found in undenatured whey proteins.

L-Glutamic Acid- In the proteinogenic group of twenty amino acids, the group that is deemed the building blocks of proteins, L-Glutamic Acid is one of the more commonly known ones. The reason for this fame are the carboxylate anions and salts of the glutamic acid, the glutamates. Glutamic acid is present in many fermented or aged food sources, such as cheese and soy sauce, but also in yeast extracts. The sodium salt of glutamic acid, monosodium glutamate, is a very popular and widely used food additive. Glutamate is an extremely important molecule in cellular metabolism. Glutamate is also one of the most commonly occurring excitatory neurotransmitters. Glutamate has been also identified as a precursor to GABA inhibitor. Glutamic acid is deemed responsible for one of the five basic tastes, the human taste sense commonly called umami.

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 which is present in proteins. It is furthermore one of only twenty amino acids located there and is considered essential for human infants. Older children and adults are able to synthesize histidine, which thereafter is deemed non-essential. Histidine is viewed as a precursor for the biosynthesis of histamine, but also of carnosine. The enzyme necessary for the synthesis of histidine into histamine is called histidine decarboxylase. Histidine transmiase is able to transfer L-Histidine into (imidazol-5-yl)pyruvate and L-glutamate. L-Histidine is deemed necessary also for the utilization and regulation of other essential trace minerals by the human body, these minerals are manganese, iron, zinc, copper and molybdenum. With help of histidine kinase, protein L-Histidine and adenosine triphosphate can be converted into adenosine diphosphate and protein N-phospho-L-histidine.

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-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- 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 amino acid that is essential to the body, but must be obtained from various sources, as it is not produced by the body. L-Threonine is a well known amino detoxifying agent which works in the liver, preventing the build up of fat. It assists in metabolism and helps the intestinal and digestive tracts to function with absolute ease. L-Threonine also helps in the formation of enamel, elastin, collagen and muscle tissue. Foods rich in Threonine are leafy vegetables, poultry and pork, but it can be obtained from various pulses, whole grains, nuts and fruits like peaches and pairs. Commonly used in the relief of stress and anxiety, L-Threonine helps the consumer to have a completely healthy mental and physical style of living.

L-Tryptophan is the L-stereoisomer of the essential amino acid tryptophan. All amino acids consist of a basic structure which is different only in their special groups called functional groups. The amino acid tryptophan has an indole functional group. Tryptophan is an essential amino acid. This means that it must be ingested from an outside source. An example of a food item rich in this amino acid is banana. Basically, all amino acids are important for the body because they are the building blocks of proteins. Amino acids also possess some special features which vary according to the type of amino acid. Tryptophan also serves as a biochemical precursor of various substances in various reactions. It is a precursor of the neurotransmitter serotonin which is involved in regulating mood and gut movements. It can also act as a precursor of niacin.

L-Tyrosine is an amino acid taken to enhance the functions of the thyroid gland. It provides essential supplements to the body for fighting serious ailments. L-Tyrosine is a natural cure mainly for hypothyroidism and many other illnesses including protection of skin from the UV rays and depression. People suffering from hypothyroidism lack tyrosine and therefore do not respond to iodine supplements. Iodine supplements are of no use without tyrosine. Using L-tyrosine replaces vital amino acids which people having hypothyroidism lack. It produces thyroid hormones namely, norepinephrine, dopamine and epinephrine. L-tyrosine must be used by those who have a family history of under active thyroids and by those who have not got benefits from dieting efforts. L-tyrosine is taken in doses of 500mg 2 to 3 times everyday. People having high blood pressure must be cautious while taking this supplement.

L-Valine- L-Valine is one the three Branched Chain Amino Acids (BCAAs). The other two BCAAs are L-isoleuine and L-leucine. L-Valine is required by the body for the proper function of the nervous system and the brain. L-Valine is not processed by the liver; instead, it goes directly to the muscles. It helps enhance muscle growth and help it to recover faster after an intense workout. It also helps in muscle tissue repair and maintains the proper amount of nitrogen in the body. It can also be used as an energy source that gives energy and strength to the muscles. L-Valine has other benefits; it is also helpful in liver regeneration, improvement of insomnia and nervousness, and is an effective appetite suppressant.

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.
