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.

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 is a non-essential amino acid which one of the most abundantly, naturally occurring amino acids in the human body. It is also unique in that it is one the few amino acids which can directly cross the blood-brain barrier. Glutamine is found in the blood and skeletal muscles. Glutamine is also abundantly present in a large variety of foods including chicken, beef, eggs, dairy, whet, cabbage, beets, spinach, parsley etc and hence it’s very rare to have a glutamine deficiency. Supplements however may need to be taken in case of illness or injury. Glutamine has a major role in protein synthesis. It is also essential for regulating the acid-base balance in the kidney through the production of ammonium. Glutamine is a substrate for DNA synthesis and aids in immune function by acting as a precursor for rapidly dividing immune cells.

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 a necessary mineral for humans, needed for example to help form red blood cells which transport oxygen around the body. Fortunately there are plenty of good sources available for both the omnivore and the vegetarian or vegan These include liver, meat, beans, nuts, dried fruit , also whole grains and many of dark green leafy vegetables, although some such as spinach also contain substances that prevent the absorption of iron as do caffeine based drinks such as tea and coffee. On the other hand the drinking of fluids containing vitamin C aids the body in its necessary task of absorbing iron.

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 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.

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 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.

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.
