Tyrosine

                   This can be called an anti-stress amino acid. Tyrosine is also advantageous for nervousness, irritability, depression and despondency. Research has established this amino acid to be effectual in the management and control of depression in conjunction with glutamine, tryptophan, niacin and vitamin B6. It is also useful in the treatment of allergies and high blood pressure. When tyrosine is taken, a supplement of Valine, another important amino acid should not be taken as Valine may block tyrosine`s entry to the brain.

Arginine & Cystine

Arginine
This is called the "fatherhood "amino acid as it comprises 80 per cent of all male reproductive cells. It is crucial for normal growth. Serious lack of this amino acid reduces the sex instinct causing impotence. It is found in most vegetables, in particular, green and root vegetables.

Cystine
It provides resistance by building up white cell activity. It is an indispensable amino acid. It is one of the mainstays of health as it is necessary for the proper formation of skin and helps one recover from surgery. It is used in the healing of skin diseases, for low white blood cells counts and for some cases of anaemia.

Histidine

  

                 This helps tissue development and repair. It is active in producing normal blood supply. It is also vital to the formation of glycogen in the liver. It is found in the root vegetables and all green vegetables. Studies show that the free form of histidine in the blood is low in cases of rheumatoid arthritis and if taken orally, may possibly slow down the symptoms of this illness. Oral histidine has, however, a propensity to stimulate hydrochloric acid secretion in the stomach and persons who are vulnerable to an overabundance of acid and also those who have ulcers should keep away from taking pure histidine. Orthopaedic and joint pains are caused by lack of histidine.

Threonine

                This amino acid is found in various types of milk and is a major constituent in cow`s milk. Other sources are seeds, carrots, nuts, and green vegetables. Without threonine, a child`s development will be deficient and there will be malfunctioning of the brain. This amino acid has a dominant anti convulsive effect.

Phenylalanine

                     This is indispensable to the production of hormone adrenaline; to the production of the thyroid secretion and the hair and skin pigment, melanin. It is useful in weight control because of its effect on the thyroid. Its use before meals suppresses the appetite to a large extent. It is necessary for the efficient functioning of kidneys and bladder. Major source are nuts, parsley, seeds, carrots and tomatoes. An important recently discovered restorative use of phenylalanine is its capacity to overcome most conditions of lethargy through stimulation of adrenaline.

Isoleucine & Leucine

Isoleucine
               This amino acid is vital for maintaining the nitrogen balance fundamental to all body functions. It also regulates metabolism of the thymus, spleen and pituitary glands. Rich sources are sunflower seeds, all nuts, except cashew nuts, avacados and olives.

Leucine
           It is the compliment of isoleucine, with a similar chemical composition although in different arrangement. Its functions and sources are also the same.

Valine

                            Valine is an indispensable body growth factor, chiefly for mammary glands and ovaries. Valine is directly linked with the nervous system. It is necessary for the prevention of nervous and digestive disorders. Major sources are almonds, apples and most vegetables. Lack of this amino acid makes a person sensitive to touch and sound.
