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 vital in human nutrition as the adult human body contains 3-4 grams of iron. Haem-iron and non-haem iron are the two types of iron. Foods rich in haem-iron include meat, liver, fish, and poultry. Foods that are high in non-haem iron are those of vegetable origin, like green leafy vegetables, cereals, legumes, oilseeds, nuts, dry fruits and jiggery. Iron is vital for numerous body functions, including hemoglobin formation, brain development and function, muscle activity, regulation of body temperature and catecholamine. Deficiency of iron affects immune system, reduces the number of T-cells and production of antibodies. Iron is also necessary for binding oxygen to body cells as its main function is oxygen transport and cell respiration. It works as an anti-cancer agent. Iron increases energy level of the body, improving physical performance. It prevents insomnia.

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 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. 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 can be used to help with skin health. It also has been known to stop hair loss & aid normal hair growth. 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- 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-Hydroxyproline is a hydroxylated form of the amino acid proline. L-Hydroxyproline is formed when body makes proline and combines with Vitamin c. It is a major element of collagen, a protein that is responsible for giving the skin strength, elasticity and flexibility. L-Hydroxyproline promotes the formation of collagen and elastin that keeps skin healthy. L-Hydroxyproline prevents easy bruising, internal bleeding and breakdown of tissue ligaments and tendons. It also decreases the risk of blood vessel damage. L-Hydroxyproline also helps in retaining moisture and in cell proliferation. It is commonly used in anti-aging skin products like creams and lotions because of its properties.

L-Isoleucine- The second of three branched chain amino acids it is important in blood sugar regulation and producing hemoglobin. After exercise, it is responsible for muscle recovery and important in the metabolism to produce energy.

L-Leucine, is an alpha amino acid which is extremely essential in the everyday functioning of the body. Leucine is also an essential amino acid, meaning that the human body cannot synthesize it and it has to be ingested. And is found in brown rice, nuts and whole wheat bread products. L-Leucine as an essential amino acid increases the synthesis of muscle protein and thus slows the degradation of muscle tissue. L-Leucine is also utilised in the liver, adipose tissue and muscle tissue. Simply put, L-Leucine supplies the body with energy when engaging in an athletic activity, it preserves the glucose stored in muscle tissue and it works to heal bone, skin and muscle tissue. It is also a ‘limiting nutrient’ thus it helps the body make use of the proteins ingested. Leucine deficiency can lead to depression, muscle weakness, low energy etc.

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- 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 is an essential amino acid made from proteins during the digestion by the action of proteolytic enzymes. It promotes the production of serotonin that is involved in vasopressure regulation. It also helps regulate blood pressure, and prevents atherosclerosis. It is also involved in treating depression, anxiety, enhance mood, improve sleep, and control impulses. It may also be used for treatment of attention deficit patients. It also helps in weight loss because it curbs the cravings and suppresses appetite. L-Tryptophan also plays an important role in the production of niacin. It helps relieve and alleviate the symptoms of fibromyalgia. It also promotes the production of growth hormones.

L-Tyrosine is an amino acid that may be found in foods such as meats, dairy products, wheat, fish, and oats. It plays an important role in the production of neurotransmitters such as L-dopa, dopamine, norepinephrine, and epinephrine that aids in the proper functioning of the brain. It prevents feelings of anxiety, irritability, frustration, sadness and depression. It also helps in losing weight because it aids in suppressing appetite and cravings. It also has the ability to enhance the libido. L-Tyrosine also protects the skin from UV light rays by being converted into melanin. It also benefits people with Alzheimer’s disease and dementia.

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 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.
