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, a mineral vital to the human body, Calcium is necessary for many bodily functions, such as muscle contraction, and proper heart function.

Iron is a necessary mineral for humans, needed for example to help form red blood cells which transport oxygen around the body. Fortunately there are plenty of good sources available for both the omnivore and the vegetarian or vegan These include liver, meat, beans, nuts, dried fruit , also whole grains and many of dark green leafy vegetables, although some such as spinach also contain substances that prevent the absorption of iron as do caffeine based drinks such as tea and coffee. On the other hand the drinking of fluids containing vitamin C aids the body in its necessary task of absorbing iron.

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 one of the most common naturally occurring amino acids. In adults, arginine is deemed semi-essential, while for infants it is believed to be essential alpha amino acid. The functions of L-Arginine are multiple, it plays roles in the healing of wounds, immune function, hormone release, ammonia removal and cell division. It is also believed to be a precursor of nitric oxide, increasing the muscle mass, reduce body fat, decrease blood pressure and a dozen other functions, such as reducing the recuperation time after a serious injury, bone fractures and similar in particular. Since that L-Arginine can be produced by the human body, ingestion is conditionally not necessary, but sources include dairy products, meat such as beef and pork, poultry, but also vegetables like nuts, seeds, oatmeal, wheat flour and more.

L-Cysteine is one of the many naturally occurring amino acids. It is further termed as a protein amino acid. Promoting the stomach lining health is one of the main functions of l-cysteine. It also helps in correction of situations where the essential nutrients from food sources are not being absorbed properly. Generally, most people do not need supplements for obtaining l-cysteine amino acid. It is can easily be found in vegetable, meats and dairy products. Although, l-cysteine is also available in the form of cysteine, which is found in plenty of protein enriched foods. Cysteine is one of those amino acids which are not destroyed by cooking. On the contrary, research shows that cooking of food rich in cysteine may help you absorb them better.

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 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 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 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- 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.

Vitamin A is needed by the retina of the eye in the form of a specific metabolite(the light-absorbing molecule retinal). This molecule is absolutely necessary for both scotopic and color vision. It also palys an important role in the health or our skin, bone metabolism, immune function. It is also commercially produced and administered as esters such as retinyl acetate commonly called Vitamin A acetate. Its defeciency can cause blindness. Other problems include impaired immunity, hypokeratosis (white lumps at hair follicles), keratosis pilaris and squamous metaplasia of the epithelium lining the upper respiratory passages and urinary bladder to a keratinized epithelium.

Vitamin C is an obvious essential nutrient and a deficiency of this will cause scurvy. It is also an antioxidant and acts as an electron donor for eight different enzymes.
