L-Arginine refers to the amino acid having numerous functions and this helps the body in getting rid of ammonia. This is useful in making compounds such as creatine, L-proline and L-glutamate. This is easily converted into glycogen and glucose, if required. L-arginine is useful in making nitric oxide. L-arginine helps in improving the relaxed blood vessels such as erectile dysfunction and atherosclerosis. L-arginine is effective in protein formation as well and this stimulates the hormones growth and prolactin. L-arginine is useful in making nitric oxide that decreases the stiffness in the blood vessels and enhances the blood flow thereby improving the blood vessel functions. L-arginine is strictly prevented from using after a heart attack. L-arginine is useful for erectile dysfunction that relaxes the muscles that is enveloping the blood vessels supporting the penis. The blood vessels dilate in the penis and increase the flow of blood and helps in maintaining the erection. L-arginine repairs wound. However, L-arginine is produced in the liver and kidney and the food sources are dairy products, nuts, poultry, fish and meat.

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.

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-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 essential amino acid that produces histamine, which aides with allergy systems.

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 a hydrophobic essential alpha amino acid, which as an additive under the name L-Leucine has an E number E641, which classifies this amino acid as a flavor enhancer. The natural source of leucine includes whole wheat products, several species of nuts and brown rice. L-Leucine is one of the most abundant amino acids found in skeletal muscle tissues. L-Leucine became in recent times a very popular dietary supplement, particularly with the body building communities, because of the evidence that it slows down the degradation of muscle tissue in rats by elevating the production of muscle proteins. There are additional claims in circulation, which state that L-Leucine also controls the nitrogen balance and aids to the mental and cognitive abilities during high power workouts.

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 is an essential amino acid, actually an alpha amino acid, furthermore classified as nonpolar. This proteinogenic amino acid is the only one, besides cysteine, which contains sulfur. Methionine serves as an intermediate of phospholipids, such as phosphatidylcholine, but also lecithin, taurine, carnitine and cysteine. If methionine cannot be properly synthesized, the condition can lead to atherosclerosis. While it must be supplied with diet, this amino acid is deemed a powerful antioxidant, believed to be a scavenger of free radicals, and may assist with the breakdown of fats. Sources of L-Methionine include poultry and related products, including eggs, but also other meats, such as beef, cheese and fish. Methionine adenosyltransferase is converting methionine to S-adenosylmethionine, SAM, which in turn is involved in the creation of creatine, epinephrine, melatonin and further substances.

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- 2-amino-3-hydroxybutanoic acid, or L-Threonine, an enantiomer of Threonine, which is an essential amino acid, needs to be ingested by way of diet, predominantly through Threonine containing proteins. There are two ways how Threonine can be metabolized, namely conversion into pyruvate by utilizing Threonine dehydrogenase, whereby an intermediate can thiolyze with CoA, producing acetyl-CoA and glycine; and the second possibility, where Threonine is changed into alpha-ketobutyrate, utilizing serine dehydratase, towards becoming succinyl-CoA. Succinyl CoA is a CAC intermediate, which means that it is a part of the citric acid cycle. The citric acid cycle is a vital part of the metabolic pathway which is securing the conversion of carbohydrates, proteins and fats towards usable energy. Foods containing Threonine are meat, poultry and fish and related products, cottage cheese, sesame seeds and lentils.

L-Tyrosine is a non essential amino acid occurring in the body. L-Tyrosine may be created from the synthesis of phenylalanine which is also an amino acid. It is one of the building blocks of proteins in the body. It is also a precursor for several neurotransmitters such as L-dopa, dopamine, epinephrine and norepinephrine. It helps treat and prevent illness such as Parkinson’s disease, Alzheimer’s disease, depression and other such mood disorders. It also helps protect the body from free radical damages. It also helps protect the skin from UV rays damages on the skin by aiding in the production of melanin. It also helps in increasing the metabolic rate that speeds up muscle building and fat loss. It also increases the endurance.

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.

Taurine ,an essential amino acid, contains cysteine and methoinine. It is normally added to energy drinks to improve the level of endurance during workouts. It acts like a diuretic and retains magnesium and potassium within the cells and gets rid of sodium. It helps eliminate swelling and accumulation of fluids and enhances the functioning of the kidney. Taurine also helps maintain a proper balance of calcium, lowers the blood pressure, prevent the development of gallstones and strengthens the muscles of the heart. Additionally, it even supports diabetes patients, as it inhibits resistance to insulin and hyperglycemia. Taurine deficiency can impair vision, develop epilepsy and could lead to problems like fat metabolism. It naturally detoxifies our body and is required in small doses of 1 and 4 grams everyday.

Vitamin B6 is a water-soluble member of the vitamin B complex. It exists in thre forms and often occurs in nature as a mixture of these three forms. Vitamin B6 is involved in protein, fat, and sugar metabolism.
