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.

Alpha Galactosidase is a natural enzyme that helps to break down complex sugars like polysaccharides and oligosaccharides into simple sugars in the digestive tract. Polysaccharides and oligosaccharides are found in foods such as legumes and cruciferous vegetables. Alpha Galactosidase, thereby not only makes it easier to digest these foods but also helps to reduce flatulence. Otherwise, these complex sugars on being fermented by the natural flora of the large intestine may cause bloating, gas and discomfort. Alpha Galactosidase, obtained from the fungus Aspergillus niger, is also available as a dietary supplement in the form of tablet as well as liquid.

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.

Bromelain - There are numerous health benefits of bromelain. Studies have shown that bromelain helps improve both the health and quality of life in a variety of ways. It is an enzyme that breaks down proteins in the body and helps ease and prevent a number of diseases due to its valuable medicinal properties. It is beneficial for arthritis patients since it helps decrease swelling and inflammation which can be caused by this disorder. Due to its anti-inflammatory properties, bromelain can also aid in treatment of rheumatism. It also has blood thinning properties, and thus it can be efficacious in preventing and treating clots in blood and plaques in arteries that in turn helps prevent cardiovascular problems. It helps alleviate aches and pain.

Cystine is an amino acid containing sulfur, which assists in forming healthy skin, bones, hair, and connective tissue. It also is needed to make glutathione, a natural antioxidant that fights free-radical damage. Every molecule of cystine is formed from two molecules of cysteine, which is another sulfur-containing amino acid very similar to cystine. It is needed for proper vitamin B6 use and is also beneficial in healing burns and wounds, breaking down deposits of mucus in diseases like bronchitis and cystic fibrosis. Cystine enhances the glutathione level in lungs, kidneys, liver, and bone marrow, which can have an anti-aging impact on the body by decreasing age spots. It is a detoxification agent protecting the body against damage of cigarette smoking and alcohol, and can help prevent hangovers, and liver and brain damage.

Glutamine- The standard genetic code has 20 encoded amino acids. Glutamine is one those encoded amino acids. Research shows that prolonged consumption of glutamine is effect in anabolic muscle growth. The most non essential amino acid produced by the human body in abundance is the glutamine. The blood brain barrier is something which is crossed directly by very few amino acids. Glutamine is one of those few acids. Skeleton muscles are where the glutamine is stored in the body. It can also be found circulating in the blood stream. In case of illness or injury, it becomes extremely important to consume food high in this amino acid. There are a lot of external dietary sources that provide the amino acid glutamine. Poultry products, dairy products, fish, vegetables like spinach, cabbage, beets; even vegetable juices and fermented food items are a good source of glutamine.

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-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-Isoleucine is an essential alpha-amino acid that is considered both, a ketogenic and a glucogenic amino acid. Since that L-Isoleucine is an essential amino acid, it cannot be synthesized by the body, therefore it needs to be ingested. The primary source of L-Isoleucine is as a component of proteins. It has become a prominent component of nutritional supplements, mostly with the body building and similar athletic communities, where it is believed that L-Isoleucine has the capability to increase endurance, but also to repair muscle tissue. It has been observed that L-Isoleucine ingestion allows power athletes to recover easier from very tough trainings and exhausting activities. This branched chain amino acid is one of the three main BCAA in the body, the other ones being valine and leucine.

L-Leucine is not prepared in the body but can be obtained through food items like brown rice, whole wheat bread and nuts or dietary supplements. It provides power and endurance. It ensures the well being of the lean muscle tissue, maintains the body’s nitrogen balance and supplies energy especially during exercise. It also assists the healing process and preserves and builds muscles. It is ideal for sportspersons. L-Leucine is also known to increase the secretion of Human Growth Hormone resulting in healthy joints, the reduction of body fat and slowing down of the aging process. It is also useful to people with Diabetes and kidney and liver problems. In the case of a deficiency, the body will not be able to use any proteins efficiently.

L-Valine is the third branched chain amino acid and is required for muscle metabolism, repairs and regenerates tissue, and maintains the body's nitrogen level. It also is used as a muscle energy source and preserves the use of glucose.

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 an essential amino acid that is sometimes also referred to as amino acid K. It is effective in preventing atherosclerosis which causes the walls of the arteries to harden caused by deposits of lipoproteins or fats. It is able to loosen and preventing the deposits of fats and reduces the risks of stroke and hypertension or high blood pressure. It also promotes the production of carnitine that converts fatty acids into energy. It also controls the blood pressure level. Lysine also helps in the absorption of calcium that keeps the bones healthy. It also promotes collagen production that is important in maintaining the joints and connective tissues healthy.

Methionine is an a-amino acid classified in the non polar group of amino acids. All amino acids have a basic structure in which there is a central carbon atom, attached with the amine, carboxyl, and functional groups as side chains and also a hydrogen atom. Only the functional group varies in different amino acids and the properties, and thus the importance of the amino acids varies according to the functional groups. Methionine has a non polar thioether group as its functional group. Most of the advantages of methionine are based on the fact that the body can convert it into very useful substances. On its own, it is a potent antioxidant and helps in the breakdown of fat. When converted to creatine monohydrate, it helps muscle building.

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 proteinogenic amino acid that occurs naturally in the body. It is derived from the metabolite glycine. It is important to overall health, both physical and mental, as well as the proper functioning of the brain and central nervous system. It is an important factor to the biosynthesis of purines and pyrimidines, which directly affects the body’s metabolic rate. Serine forms the phospholipids that are needed to make cells in the body. Promotion of a healthy immune system is also one of serine’s benefits, as it produces immunoglobulins and antibodies. Serine produces trypophan which is an amino acid that is used to make serotonin.

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.
