Glycine

Glycine retards muscle degeneration by supplying additional creatine, a compound that is present in muscle tissue and is utilized in the construction of DNA and RNA. Glycine is essential for the synthesis of nucleic acids, bile acids, and other nonessential amino acids in the body. It is used in many gastric antacid agents. Because high concentrations of glycine are found in the skin and connective tissues, it is useful for repairing damaged tissues and promoting healing.

Glycine is necessary for central nervous system function and a healthy prostate. It functions as an inhibitory neurotransmitter and as such can help prevent epileptic seizures. Glycine has been used in the treatment of manic (bipolar) depression, and can also be effective for hyperactivity.

Having too much of this amino acid in the body can cause fatigue, but having the proper amount produces more energy. If necessary, glycine can be converted into the amino acid serine in the body.

Glycine is a nonessential amino acid used by the body to build proteins. It is present in considerable amounts in prostate fluid. Glycine may play a role in maintaining the health of the prostate, since a study of forty-five men with benign prostatic hyperplasia (BPH) found that 780 mg of glycine per day for 2 weeks and then 390 mg for the next 2 1/2 months, taken in combination with equal amounts of the amino acids alanine and glutamic acid, reduced symptoms of the condition. This effect has been reported by others.

Glycine aids in treating certain types of low pH in the blood (acidemia), in particular those due to an imbalance of leucine, which manifests itself as bad breath and body odor. Improves low pituitary gland function.  Aids in the treatment of muscular dystrophy, due to its ability to produce creatine, which is vital for muscle function. Used in treatment of gastric hyperacidity, glycine is also a component of some gastric antacid medications. Used in the treatment of hypoglycemia, since it stimulates glucagon production, which activate and release glycogen into the blood stream as glucose.

Where is it found ?

Glycine is found in many foods high in protein, such as fish, meat, beans, and dairy.

Who is likely to be deficient ?

Few people are glycine deficient, in part because the body makes its own supply of the nonessential amino acids.

How much to take

Healthy people do not need to supplement glycine. A nutritionally oriented physician should be consulted for the supplemental use of glycine for the support of serious health conditions.

Side effects

No clear toxicity has emerged from glycine studies; however, individuals with kidney or liver disease should not consume high intakes of amino acids without consulting a health-care professional.

Caution

While the right amount increases energy, excess amounts may cause fatigue.
