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 needed by the body for the proper functioning of the liver, skin, joints, and muscles. It helps improve the immune system by increasing the T-lyphocytes output from the thymus gland. Arginine also neutralizes the effects of ammonia and toxic substances by detoxifying the liver. It is beneficial to most athletes particularly body builders because arginine helps in the production of creatine in the body and stimulates the excretion of growth hormones that aids in the development of muscle mass. It also helps improve the metabolism and in fat loss. Arginine also promotes the healing and repair of damaged tissues.

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 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.

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 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.

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 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.

Milk is a liquid produced by the mammary glands of mammals. Humans generally consume milk of goats and cows. Cow’s milk contains proteins, fats, lactose and minerals. It supplies 66 kcal of energy per 100 grams. Studies show that low-fat milk can reduce risk of heart disease and arterial hypertension. It contains Conjugated linoleic acid. Milk is shown to decrease risk of insulin resistance, and full fat milk is shown to slightly increase fertility in women. Milk is a good source of protein and many protein supplements are also manufactured from milk, which are used by athletes and bodybuilders for muscle growth.

Phenylalanine is an essential amino acid that plays an important role in the formation of proteins. It is converted into tyrosine in the body which stimulates the production of dopamine, epinephrine and norepinephrine. It helps treat and manage the symptoms of Attention Deficit Hyperactivity Disorder (ADHD), depression, and Parkinson’s disease. It also alleviates the symptoms from alcohol withdrawal. It also has the ability to reduce pains caused by osteoarthritis, rheumatoid arthritis and premenstrual syndrome (PMS). Phenylalanine also treats vitiligo, a skin pigmentation disorder. Phenylalanine may also help in weight loss because it aids in suppressing the appetite and cravings, and at the same time, it promotes the production of energy.

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.

Taurine is an amino acid found within muscle tissue. It is the second most abundant amino acid found in the body.

Threonine-The essential amino acid threonine is found throughout the body's circulatory, skeletal and central nervous systems and is essential for maintaining balance throughout the body while assisting in the production of elastin and collagen that are needed for healthy skin. Threonine is also beneficial for optimal liver functioning and promotes a healthy immune system by assisting with the production of antibodies. Threonine has also been used in various formulations to strengthen mental clarity and sharpen focus. Threonine can be found in abundance in various dairy foods, beans, nuts, wheat germ, some vegetables, eggs, and most meats, or in supplement form.

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 the concentrated form of whey protein, which contains sixty five percent beta-lactoglobulin , twenty five percent alpha-lactalbumin (~25%), eight percent serum albuminand and two percent immunoglobulins. Whey protein concentrate contains low level of fats and cholesterol, and a high level of carbohydrates and bioactive compounds. It is twenty nine to eighty nine percent proteins by weight. Whey protein concentrate is mostly used by athletes and in general medical application because it provides proteins and low quantities fats, cholesterol and carbohydrates. It is not the favorite supplement for body builders because they generally use whey protein isolate, which contains more than ninety percent protein by weight.

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.
