L-Arginine helps in forming proteins and is responsible for releasing the bodies growth hormones. In addition it makes nitric oxide. This is a vessel relaxant, which helps to improve blood circulation.

L-Aspartic Acid is an amino acid which is extremely essential to the body. It has a variety of beneficiary properties, in that it acts as a detoxifier by combining with other acids to remove toxins from the blood stream, and helps in building immune system antibodies and converts carbohydrates into muscular energy. People with lowered levels of L-Aspartic Acids may find themselves susceptible to fatigue and tiredness. People tend to feel that they have no energy to continue with a particular activity, and replenishing the body’s levels of L-Aspartic acid may be just the thing to get back to normal. Natural sources rich in L-Aspartic Acid are animal protein, avocado, asparagus and oats. Dietary supplements can also make available, the required amounts of L-Aspartic Acid.

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 one of the amino acids present in proteins. In infants histidine is an essential amino acid and as the age advances it becomes a non-essential amino acid which can be synthesized by the body. L-Histidine is most commonly known as being a precursor to the allergy symptom producing hormone histamine. However histadine does have other roles to play in the body beyond causing allergies. L-Histadine is required by the body to regulate and utilise essential minerals like copper, zinc, iron, manganes etc. L-Histidine is also important in forming metal bearing enzymes like the antioxidant super oxide dismutase, iron storage proein ferritin, red blood cell haemoglobin etc. Depletion of L-Histidine can be recognised by low plasma concentrations of the amino acid, high blood serum levels.

L-Isoleucine is one of the nine essential amino acids that is not produced in the body. It can be obtained from animal sources like liver, fish, eggs, chicken, meat and vegetable sources like rye, cashew nuts, almonds, lentils, chickpeas and soy proteins. The metabolism of L-Isoleucine takes place in muscle tissue. It is needed for the formation of hemoglobin and stabilizes and regulates blood sugar and energy levels. It is also known to increase endurance levels and helps in the recovery of muscles after exercise. It strengthens the immune system’s ability to fight off infections and increases the level of growth hormones and insulin to maintain the body’s balance. A deficiency leads to a number of physical and mental disorders with symptoms similar to hypoglycemia.

L-Leucine is an essential amino acid that works together with isoleucine and valine, forming the three branched chain amino acids (BCAA). Leucine is easily converted by to body to glucose, helping to regulate and maintain the blood sugar level. Leucine promotes muscle recovery, muscle repair and provides the body with energy. It also helps in burning fat that are least responsive to exercise and dieting. Leucine helps in toning the body and the muscles. Leucine prevents muscle loss by breaking down and converting to glucose, this prevents the body from breaking down muscle tissues to create energy, particularly during intense workouts and heavy weight lifting.

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- Methionine is a nonpolar essential alpha amino acid containing sulfur; one of only two proteinogenic amino acids besides cysteine. Methionine is vital to several biosynthesis processes of phospholipids as an intermediate, the prominent list includes taurine, lecithin, carnitine, phosphatidylcholine and cysteine, just to name a few. This water soluble antioxidant assists in the lipid breakdown and works against free radicals. Just like many such amino acids, it can be obtained through ingestion of dietary proteins, such as meat, eggs, cheese, fish and poultry, but some levels are also available from spinach, sesame seeds and Brazil nuts. It has been found that an inadequate conversion of methionine may cause atherosclerosis. This glycogenic amino acid is also part of other biochemical reactions, like the creation of S-adenosylmethionine, which in turn is a part of the synthesis of epinephrine, melatonin and creatine, among others.

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-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 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.

Taurine is basically an amino acid that is not formed by the body. It is found freely in the bloodstream and in tissues. It is also found in abundance in the skeletal system, the heart and the nervous system. During times of extreme physical activity, the amounts of taurine in the body are depleted. Taurine has a tendency to act as a metabolic transmitter and can also be used as a detoxifying agent. It has been added to a number of products for infants as well. The popular energy drink ‘Red Bull’ is well known for its taurine content. Taurine is also recommended for use by people who suffer from manic depression. Taurine is tested and has proven to be an extremely safe dietary supplement.

Vitamin B6 is soluble in water and is essential for good health. Our nervous system is dependent on this vitamin to function properly. It keeps the thymus, lymph nodes and the spleen that make white blood cells healthy, through cellular growth and protein metabolism. A deficiency in this vitamin can lead to a weakened ability to fight infections and will weaken the immune system. Vitamin B6 helps in the formation of Hemoglobin which increases the oxygen that is carried to the tissues. A deficiency can cause a type of anemia. Vitamin B6 helps to convert carbohydrates and other nutrients into glucose which maintains the sugar levels in our blood stream. Vitamin B6 is available in meat, fish, fortified cereals, poultry, some fruits and vegetables.
