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 an important amino acid formed by the body and obtained through various diets. It is formed in the lungs and mainly stored in the muscles of the body. Many immunity cells rely on glutamine for energy. It removes excess ammonia from the body and is required for normal functioning of the brain and digestion. Glutamine levels are reduced by certain medical conditions, such as injuries, surgery, stress and infections. Thus reduction in levels of glutamine slows the healing process. For people who exercise a lot, glutamine supplements may be used for recovery of over stressed muscles. Proteins from plants and animals like milk, yogurt, cottage cheese, pork and poultry, beef, ricotta cheese, raw parsley, cabbage, raw spinach, etc are an excellent 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.

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.

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 is the chemical element found in the periodic table with the atomic number 12. This alkaline earth metal is one of ten most common elements in the known universe and also very prominently present in the human body. It manipulates polyphosphate compounds, most prominently the DNA, RNA and the ATP. Numerous enzymes rely on magnesium ions to function properly. Most common application of magnesium in medicine may be the addition to antacids and laxatives. This metal is not found as a free element naturally on Earth, generally the metal is obtained through electrolysis of magnesium salts. The most common deficiency in the United States with staggering two thirds of the population is the magnesium deficiency. Magnesium can be obtained through vegetables, tea, cocoa, cereals, coffee, nuts and spices.

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, 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.

Phosphate (Phosphorus) is essential for normal heart and kidney functionin. It speeds up the healing of broken bones and other injuries and functions to metabolize fats and starches for energy, as well as being necessary for correct nerve impulses and for niacin assimilation. Phosphorus is needed for the growth, maintenance, and repair of all tissues and cells, and for the production of the genetic building blocks, DNA and RNA. Phosphorus is also needed to balance and metabolize other vitamins and minerals, including vitamin D, calcium, iodine, magnesium, and zinc. It is also important for forming cell membranes, the specialised layers that enclose body cells. It is a principal mineral of bones and teeth.

Potassium- Potassium is one of the essential minerals required for proper physiological functioning of the body. It plays an important role in the regulation of heart muscles. It helps to convert glucose to glycogen. Glycogen is essential for muscle formation. Potassium also helps to propagate nerve impulses by exchanging ion within cells and also helps in muscle contractions. It helps in balancing blood pressure. It controls the proper functioning of kidney. An average adult needs 3-5 gm of potassium daily. Due to deficiency of potassium, body observes tiredness. Other deficiency symptoms are weakness of muscles, low blood pressure, vomiting, poor kidney functions and Heart arrhythmias. Severe potassium shortages quickly direct to electrolyte disproportion which involves malfunctioning of nerves, kidney and heart.

Sodium is part of the extracellular fluid of many multicellular creatures, not least mankind. It is needed for instance in nerve conduction and to balance the acid levels in the body. It is necessary for the functioning of organs such as the liver, intestine and kidneys in their work of ridding the body of toxins However there is an optimum intake. Above this there are problems such as a rise in the blood pressure. Also an excess of salt in the diet will draw fluid out of the cells by the process of osmosis. On the other hand a lack of sodium will lead to too much water in the body the brains cells will actually be flooded.

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 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 an essential mineral that is used in many healing processes to speed up the healing process in instance that include sunburned skin, diaper rash and helps prevent premature aging of the skin.
