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 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 essential to all living cells and is a vital component to a healthy diet. Calcium absorption for the body largely depends on magnesium to facilitate this.

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) is a fatty acid essential for a variety of metabolic development. MCT, which stands for medium chain triglycerides, is used for curing patients suffering from mal-absorption syndromes or malnutrition. MCT are short in length does not need bile salts for digestion and the energy for utilization, storage and absorption. They are water-soluble and get absorbed quickly by the bloodstream and easily transported into the liver. Palm kernel oils and coconut oil are rich in MCT. Since only a tiny percent of it gets transformed into body fat, it aids weight loss provided the diet one consumes contains half the calories from MCT. Fatty acids present in MCT are known as medium chain fatty acids, some of them are capric acid, caproic acid, caprylic acid and lauric acid

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 a chemical element that is found in the periodic table with the atomic number fifteen. As a high reactive element, it is not found in clean form as a free element in nature. It is one of the most important and essential elements in the human body, being found in phospholipids that form all the membranes of cells, the DNA, the RNA and also the ATP. Cellular energy is being transported by phosphate in form of adenosine triphosphate, calcium phosphate, which are salts, are responsible for the stiffness of bones. In the average human, the amount of phosphorus in weight would be about one kilogram, whereby most of it is in form of apatite and found in teeth and bones. The daily consumption of phosphorus through dietary means is estimated at about one to three grams.

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 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-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.

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 a mineral that is present in every cell in the body. It is good for maintaining a healthy skin. It promotes healing of wounds such as bed sores, skin sore, and canker sores. It may also act as an astringent and aid in the treatment of acne. Zinc improves the immune system by activating white blood cells to fight against infections, virus, and even cancers. Zinc is also beneficial in improving the health of prostate gland and protects it against inflammation and infection. It also helps improve the brain functions such as memory retention. It also helps in the production of testosterone that improves libido, prevents low sperm count. It may also help in the formation and development of muscles.
