Glycine is a sweet tasting, non-essential amino acid that was first isolated in 1820 from gelatin and is also found in good quantity in silk fibroin. This nonessential nutrient can be manufactured from serine and threonine, so dietary intake is not essential.
Usage: Glycine is required to build protein in the body and synthesis of nucleic acids, the construction of RNA as well as DNA, bile acids and other amino acids in the body. It is further found to be useful in aiding the absorption of calcium in the body.
It helps in retarding degeneration of muscles since it helps to supply extra creatine in the body.
It is also found in fairly large amounts in the prostate fluid and may for this reason be important in prostate health.
The glycine amino acid is also used by the nervous system and its function as an inhibitory neurotransmitter makes it important to help prevent epileptic seizures and it is also used in the treatment of manic depression and hyperactivity.
Benefits Of Glycine: Glycine is an amino acid, because the human body can produce glycine on its own, glycine is not essential for human nutrition (it is not an "essential" amino acid). However, glycine supplementation is often claimed to be beneficial for the following conditions:
Strokes (to minimize damage after a stroke)
An enlarged prostate (known medically as benign prostatic hyperplasia, or BPH)
3-phosphoglycerate dehydrogenase deficiency, a rare genetic condition
Isovaleric acidemia, also a rare genetic condition
Leg ulcers (when applied to the skin).
** Sometimes glycine is also claimed to help protect the liver and kidneys and to help prevent cancer.
Glycine Use in Children:
It is not known if glycine supplements are safe for children. Even though a normal glycine intake through food is safe, it does not mean that supplementation is equally as safe. Keep in mind that children may be more sensitive to the effects and toxicities of medications or supplements. Check with your child's healthcare provider before giving your child glycine supplements for any purpose.
Research: Some of these glycine benefits may have some scientific evidence in their favor, while others have absolutely no scientific basis.
As with many supplements, claims for the benefits of glycine are sometimes exaggerated, and such claims must be evaluated critically. Most importantly, it is essential to remember that natural products should not be used carelessly, as many natural products can be quite toxic (for instance, many poisons are natural products).
