Alanine is a naturally forming chemical found in a variety of foods especially meats. This non essential amino acid is used in the production of protein. It assists the body in metabolizing various components such as glucose and can also play a part in lowering cholesterol. It is suggested that an Alanine supplement be used with people who have a diet low in protein and who may be exposed to adverse effects of a protein deficiency. Alanine is also linked to an increase in the efficacy of the immune system and a reduction of toxins in the system.

Arginine is a non essential amino acid that is naturally occurring. While considered non-essential, it is used by the human body in a number of ways. Overall, it helps improve the immune system by stimulating the thymus gland, boosting white blood cell production and stimulating the release of growth hormone. Arginine helps with wound healing by helping with cell division and is an important part of the urea cycle, helping remove ammonia from the body. Arginine also helps the body with production of nitric oxide which can help reduce mild high blood pressure and help enhance athletic performance.

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.

Glutamic Acid is an excitatory neurotransmitter, which enhances firing of neurons in central nervous system. Glutamic acid is a main excitatory neurotransmitter in brain and spinal caord. It is transformed either into glutamine or gamma-aminobutyric acid – the two other amino acids which assist in transmitting messages to brain. Glutamic acid plays a vital role in metabolism of fats and sugars, and assists in transporting potassium into spinal fluid and across the blood-brain barrier. Though it doesn’t cross the blood-brain barrier as readily as is done by glutamine, it is present in blood at high levels and may reach the brain in small amounts. The brain can utilize glutamic acid as a fuel. It assists in correcting personality disorders and is helpful in treating childhood behavioral disorders. It is also used in treating mental retardation, epilepsy, ulcers, muscular dystrophy, and hypoglycemic coma.

Glycine is known to have the ability to stimulate specific brain receptors as well as beneficial for building proteins in the body. It is used as a supplement for many ailments such as strokes or memory loss.

Histidine is an amino acid that is essential especially in infants. The adult body produces this amino acid naturally and thus it becomes a non-essential acid. However in the case of infants this is not true. This vitamin is extremely important and children may not have sufficient Histidine. The Histidine is an originator of the Histamine which is a compound that is release by the human immune system when an allergic reaction takes place. This is also essential for the repair and growth of new tissues and helps to maintain myelin sheaths (the protectors of the nerve cells). Histidine is also needed for the production of the red and white blood cells.

Isoleucine- An important essential amino acid is isoleucine which is also part of the three “branched chain amino acids” along with leucine and valine. Since it is an essential amino acid it cannot be synthesized in the body and thus isoleucine has to be ingested in the diet (almonds, chicken, eggs, cashews, fish, lentils, liver, meat etc.). Isoleucine is required for muscle recovery and also for the formation of haemoglobin. Isoleucine also assists in regulating blood sugar levels and energy levels. It is also involved in blood-clot formation. Isoleucine deficiency is present only in those people who are lacking in protein intake. Deficiency may lead to dizziness, fatigue, depression etc. Excessive amounts of isoleucine doesn’t seem to be a problem though it isn’t recommended for those with kidney or liver disease.

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.

Lecithin is needed by every cell in the body and is a key building block of cell membranes; without it, they would harden. Lecithin protects cells from oxidation and largely comprises the protective sheaths surrounding the brain. It is composed mostly of B vitamins, phosphoric acid, choline, linoleic acid and inositol. Although it is a fatty substance, it is also a fat emulsifier.

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.

Lysine is chemically abbreviated as Lys or K. It is an essential amino acid with chemical formula HO2CCH (NH2) (CH2)4NH2 and Mol. mass 146.19 g mol-1 . It is not naturally synthesized in body and needs to be taken from dietary sources. Lysine plays a vital role in protein synthesis in the body and also helps in Calcium absorption. As it helps in protein synthesis it can improve recovery of muscles after workouts and surgeries. Research also shows that Lysine aids in production of some hormones, enzymes and antibodies. It is also believed to be beneficial for people with herpes simplex infections.

Methionine is an amino acid that is found in meat, fish, beans, eggs, lentils, onions and seeds. It contains sulphur that is essential for the production of glutathione. It helps the body get rid of toxins, build strong and healthy tissues, and promote a healthy cardiovascular system. It helps breakdown fats and promotes weight loss. It also prevents the build up of fats in the arteries that reduce the risk of arteriosclerosis. Methionine promotes proper digestion and gets rid of toxins and heavy metals in the body. It helps cleanse the body from toxins. It also helps relieve pains caused by arthritis. It helps in alleviating the mood, and treat depression.

Milk is rich in calcium, phosphorous, magnesium and protein which play an important role in maintaining healthy bones and joints. Milk prevents osteoporosis and ensures the joints are well lubricated. Milk also helps keep the teeth strong. It contains casein that forms a thin film on the teeth enamel that protects it from acids in the mouth. It also helps maintain blood cholesterol level that reduces the risk of hypertension and other cardiovascular diseases. It also helps prevent Type II diabetes. Milk contains Conjugated Linoleic Acid (CLA) that protects the colon from cancer. Milk also prevents obesity as opposed to common idea that drinking milk causes weight gain.

Phenylalanine, which may aid in weight loss through the feeling of satiety or fullness by taking phenylalanine with a glass of water 20 minutes before a meal.

Proline is an amino acid. The body has the capability to produce Proline with glutamic acid. Proline works well with vitamin C, which make it more potent. It helps particularly in maintaining and repairing damaged tissues, skin and muscle. It heals damaged cartilage, and helps maintaining flexible joints. It benefits parts of the body where collagen is found, such as blood vessels, tendons, skin, bones, and including the eye. It prevents and reduces the sagging, wrinkling and aging of skin. It ensures that the body has the proper supply of collagen, guarding it against future joint and spine problems. It also enhances the immune system.

Serine is a non-essential amino acid derived from amino acid glycine and is beneficial to both mental and physical health.It is vital for proper functioning of brain and central nervous system. Serine helps form phospholipids that are needed to make every cell in the body. It also is helpful in muscle formation and maintaining a strong immune system. Proteins used to form the brain, and the protective myelin sheaths covering nerves, contain serine. It is also required for producing amino acid tryptophan, which is used to make serotonin, a chemical that determines mood. Shortage of serotonin and tryptophan has been associated with depression, confusion, insomnia, and anxiety. Decreased serine levels can lead to chronic fatigue syndrome and fibromyalgia.

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.

Threonine is an essential amino acid that plays an important role in the function of the body. It helps break down uric acid to be used for the production of purines. It helps prevent illness such as gout, and arthritis. It is also important in the synthesis of the amino acid glycine. Threonine also helps balance the blood sugar level in the body by converting glucose in the liver through gluconeogenesis. Threonine also prevents the accumulation of fatty tissues in the liver. It also improves the immune system. Threonine promotes the production and formation of proteins elastin and collagen that have strong antioxidant properties.

Tryptophan-If you have ever felt sleepy or drowsy following a big "turkey" dinner, then you have felt the effects of tryptophan, which is an essential amino acid that is found in foods that contain protein, such as turkey. Tryptophan in supplement form is mainly for those who suffer from insomnia, as an all natural sleep aid. Tryptophan may also be used for mental enhancement and as an appetite suppressant to help achieve weight loss or maintain an ideal body weight. The way that tryptophan works is by converting to serotonin in the body, which is a natural chemical that causes a sleepy feeling.

Tyrosine is a non essential amino acid derived from several sources, including soy, poultry, milk and cheese products, but can also be synthesized in the body from phenylalanine. There are twenty amino acids that are used in human cells to synthesize proteins, one of which is tyrosine. It is of vital importance to the carbon dioxide conversion into organic compounds conducted by plants, the photosynthesis. Tyrosine is also recognized as a precursor to hormones, but also alkaloids and pigments. It is furthermore viewed as a precursor to neurotransmitters; it increases the levels of plasma neurotransmitters, most prominently norepinephrine and dopamine. While under normal circumstances the effects of tyrosine are inconclusive, it has been observed as useful in stress situations and to reduce the effects of a cold, fatigue, sleep deprivation and any kind of prolonged labor.

Valine- One of the several essential amino acids present in the human body is Valine. This is also a nonpolar, branched chain amino acid which is found in high concentrations in the muscles. Since it is an essential amino acid, valine is not synthesised in the body and thus must be ingested as part of the diet. Valine is available through foods like fish, poultry, peanuts, sesame seeds, lentils and cottage cheese. Valine is essential for muscle, growth and repair of tissue and for maintaining the body’s nitrogen balance. Since it has a branched chain, valine can be used as an energy source in the muscles and thus conserves glucose. Hence valine is often used by bodybuilders to support muscle growth and provide energy. A deficiency of valine in the body, caused by the inability of the body to metabolise valine leads to the Maple Syrup Urine Disease in which the person’s urine smells like maple syrup.

Whey Protein Concentrate is one of the three major forms in which whey protein is available for human use. Whey protein concentrate is characterized by having low amounts of fat and cholesterol and about 70-89% protein by weight. They have higher levels of carbohydrates in the form of lactose and have higher amounts of bioactive compounds. Whey protein concentrates confer the same benefits that are attributed to whey protein, i.e., they are highly and readily bioavailable and contain high amounts of branched chain amino acids which are wonderful for muscle repair and growth. In addition the low amount of fat and cholesterol are an added advantage to people requiring protein supplementation without increasing their blood lipid profiles.

Whey Protein Isolate is a pure high quality protein made from cow's milk. It is a naturally complete protein containing all of the essential amino acids required by the body daily. It is a rich source of branched chain amino acids which metabolize directly into muscle tissue and are the first ones used during periods of exercise and resistance training. It is an excellent source of Lucien which plays a key role in promoting muscle growth. Whey protein also helps stabilize blood glucose levels by slowing the absorption of glucose into the bloodstream.
