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.

Cystine is a non-essential sulfur containing amino acid. Our body can supply cystine on its own. Cystine is important for vitamin B6 utilization and is a detoxifying agent. It removes toxins absorbed by body through alcohol and smoking and protects body from damage of brain and liver. Cystine increases the level of glutathione, which is a powerful antioxidant and helps in detoxifying harmful toxins in the liver. As Alpha-keratin, the protein that makes up the skin, fingernails and hair contains cystine; it is also used in anti-aging products. It is also useful for faster healing of burns and wounds, for low count of white blood cells and in skin diseases.

Glutamine is naturally created by the human body. Glutamine, a non-essential amino acid can also be found in high protein foods like red meat and nuts. Glutamine is used for proper mental function, maintaining muscle mass and controlling blood sugar levels.

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.

Iron is one of the most commonly available chemical elements which are used in the form of metal. When in the presence of oxygen and moisture, iron gets oxidized very easily. Therefore it is never available on the surface of earth. Iron is a metal whose properties can be changed by mixing it with the various other metals. Humans need iron as a daily dietary substance. There are a number of supplements available in market which provides the daily required dose of iron. But the best way to consume iron is by eating the food that is rich in iron. Fish, poultry, beans, lentils, leafy vegetables are some of food items that are a good source of iron. Although, research shows that it is easier to digest the iron found in meat and meat products than the vegetables.

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.

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

Magnesium, which is a mineral used by the body to help maintain muscles, bones, and nerves. Magnesium is also needed for energy metabolism and protein synthesis.

Manganese is a mineral that is required in small amounts to manufacture enzymes necessary for the metabolism of proteins and fat. It also aids the immune system and blood sugar balance. Manganese is also involved in the production of cellular energy, reproduction and bone growth.

Medium Chain Triglycerides (MCT) are fatty acids which are shorter in length. They therefore are similar to carbohydrates and get easily digested and absorbed and get used up as energy. It is used as an alternative source of food by patients who are unable to digest normal oils and fats. Medium chain triglycerides are water-soluble and because if their short length get absorbed into the blood stream quickly. From the bloodstream it gets directly transported to the liver. It is an immediate source of energy and only a miniscule percent of it gets converted to body fat. It is naturally found in coconut oil, milk fat and in palm oil. Medium chain triglycerides are available in capsule and in liquid form; this is obtained through the process of lipid fractionation.

Phenylalanine has also been used in the treatment of attention deficit disorder, fatigue and premenstrual syndrome. Phenylalanine also acts as an analgesic and appetite suppressant by releasing an intestinal hormone that signals the brain to feel full after eating.

Phosphate (Phosphorus) is perhaps one of the most important mineral, which in form of phosphate as an intercellular anion serves a multitude of functions. Not only are phosphates essential for the utilization of most vitamins belonging to the B complex, but they are vital for energy storage and the overall metabolism. But that is not all, phosphate is essential for healthy bones and teeth, calcium with phosphorus are required for them and soft tissues as well. But also body fluids require phosphates for excretion of hydrogen ions through the kidneys. Somewhere around one per cent of the body weight should be phosphorus in some form, therefore it is vital to supply your body with sufficient phosphates through milk, cheese, nuts, peanut butter, peas and other sources, including supplements.

Potassium is an electrolyte, a substance that maintains the fluid levels in the body. It is helpful in regulating blood pressure and heart function. Intake of potassium can benefit people suffering from hypertension. Research has found that a potassium supplement intake decreased incidence of stroke by 60 percent. It neutralizes acids and restores alkaline salts to bloodstream.  It acts along with sodium cells to maintain or restore membrane potentials. Potassium is also vital for nerve functioning and cardiovascular, and regulates nutrients’ transfer into cells and adds to muscle energy. It also helps recuperative powers, besides regulating water balance. Potassium is beneficial for eliminating wastes. It is helpful in controlling headaches and convulsions, and quickens healing of cuts, bruises and other injuries.

Sodium is the element that has the atomic number 11 in the periodic table and is commonly known as the main component in the table salt, together with chloride. Interestingly enough, it is probably the one dietary component which does require limitation rather than supplementation, since that average daily nutritional requirement is around half a gram per day. This most popular food seasoning, salt, is providing the most common source of sodium and chloride in human diets, but is generally overused and may cause health problems, such as high blood pressure, if consumed overly generously. The suggested dose of table salt, or rather the upper limit portion, would be somewhat less than 6 gram per day, according to the Dietary Guidelines for Americans, referenced by FDA. In the UK this limit is set at four grams per day.

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 is an essential amino acid that is formed from proteins during digestion by working of proteolytic enzymes. It can help enhance relaxation and improve sleep, soothe nerves and anxiety, relieve minor premenstrual symptoms, and decrease carbohydrate cravings. It is vital for production of serotonin, which is among the important chemicals involved in blood regulation. During depression, the amount of serotonin released from the brain’s nerve cells may decline. Tryptophan, by enhancing serotonin levels in the blood, can increase the antidepressant effects of serotonin. It is essential for production of niachin (B3) and needs, biotin, B6, zinc, and vitamin C to form the enzyme required for conversion. It can relieve fibromyalgia symptoms. It assists in controlling hyperactivity in children, relieving stress, and increasing release of growth hormones essential for production of vitamin B6. It can also help regulate appetite and assist in weight loss.

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.

Zinc is acknowledged as essential to the human organism. It is a trace element found in over a hundred and up to three hundred enzymes. It is the second most important mineral in the body, after iron. Zinc is also defined as an important catalytic agent, which is active in enzymatic reactions such as hydroxilation, which is essential for the protein forming amino acid proline, but also for hypoxia response. Zinc is naturally found in red meat, milk, spinach, nuts, oysters, beans and oats. Low zinc counts can attribute to a weakened immune system, interfere with muscle building, cause diarrhea and all kind of other deficiencies. In body building circles, Zinc is an important supplement, valued for the indirect increment of testosterone and the muscle building role.
