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.

Calcium, is a supple gray alkaline earth metal, which is the fifth most abundant element by mass in the Earth's crust. Calcium is also at the fifth most profuse dissolved ion in seawater by both molarities and mass. Calcium is a significant nutrient that we require in our bodies. It has many imperative functions. It helps getting strong teeth and bones and is involved in muscle contractions and blood clotting, The calcium is mainly stored in our teeth and bones. Low calcium level may lead to the bone fractures and in some cases porous bones or osteoporosis, generally in old age. The intake of calcium can drop down the high blood pressure, maintain your heart functions, avert gum disease, prevent colon and rectum cancer, and help blood to clot.

Iron is one of the most commonly available chemical elements which are used in the form of metal. When in the presence of oxygen and moisture, iron gets oxidized very easily. Therefore it is never available on the surface of earth. Iron is a metal whose properties can be changed by mixing it with the various other metals. Humans need iron as a daily dietary substance. There are a number of supplements available in market which provides the daily required dose of iron. But the best way to consume iron is by eating the food that is rich in iron. Fish, poultry, beans, lentils, leafy vegetables are some of food items that are a good source of iron. Although, research shows that it is easier to digest the iron found in meat and meat products than the vegetables.

L-Alanine- As one of the twenty alpha amino acids that are proteinogenic, which means that these amino acids are building blocks of proteins, L-Alanine is the second most abundant amino acid, with leucine being the first. This nonpolar amino acid can be produced by the body by means of reductive amination of pyruvate and some branched chain amino acids, like isoleucine, leucine and valine. Liver and tissues depend on alanine, which plays a prominent role in the glucose alanine cycle. Alanine is also involved in the removal of nitrogen from tissues to the liver, but alanine also assists in the blood sugar tapping of the body for energy requirements. Despite being a non-essential amino acid, alanine is found in meat, dairy products, fish, poultry, eggs, some beans, nuts and seeds, brown rice bran, corn and whole grains, among other sources.

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- 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-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 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 with the food additive E number code E641 is classified as a flavor enhancer. Leucine is actually an essential alpha-amino acid and a vital part of so called “buffer” proteins, such as ferritin and astacin. You can find leucine in foods such as whole wheat bread products, nuts and brown rice. As a supplement, researchers have found that leucine slows the degradation of muscles and muscle tissues through an inflated synthesis of muscle proteins. In the human body, leucine can be found in the liver, but most prominently in the muscle and adipose tissues, where it is utilized in production of sterols. In body building circles L-Leucine as a dietary supplement is very popular for all these properties, but also for the preservation of muscle glycogen, nitrogen balance maintenance and more.

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 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.

Vitamin A- Otherwise known as retinol is the vitamin which helps the eyes to adjust to changes in light levels as well as keeping the eyes, skin and mucous membranes moist. Vitamin A enters the human diet mostly from animal foods, but as well as this some plant foods contain beta-carotene, which the body is then able to convert into Vitamin A. Retinol has antioxidant properties that help the body to repair tissue and cellular damage by neutralizing free radicals. Although there seems to be some evidence that retinol may help in cases of established artery disease the American Heart Association does not recommend it as a necessary supplement until there is more evidence.

Vitamin C is well known for its powerful ability to help boost the immune system as well as fight off damage causing free radicals. As an anti-oxidant, vitamin c binds with free radicals, preventing them from damaging cells. This damage can cause early aging and even has been linked to some cancers. By taking vitamin C supplements, you are helping prevent these free-radicals, as well as giving your immune system a boost as well. Vitamin C is integral to cellular metabolism as well and a lack of vitamin C can cause a myriad of issues, including scurvy.
