As already described, glycine is a non-essential amino-acid. The human body can synthesize it from nutrients as well as other amino acids and not necessarily has to be supplied with food.
Application in case of arthrosis
It has been noticed that many people suffering from arthrosis show a disturbed glycine-metabolism and therefore lack glycine. Accordingly, a supplement of the amino acid may contribute to an improved course of the disease, ease pain or even completely eliminate it. Glycine effectively supports the building up of articular cartilages, like a study conducted by a team of scientists of the University of Granada, Spain, proved in 2007. 600 patients of different ages suffering from arthrosis have been scientifically accompanied for a longer period of time. One part of the group received glycine as supplement. After a couple of months these persons needed 50 % less analgesics. After one year, some patients were completely pain free. With the placebo receiving group no improvements were noticed.
Application for strengthening the immune system
Glycine also supports our immune system – it contributes to the formation of antibodies. Also, it forms radical catchers together with glutamine acid and cysteine (antioxidant).
Application in case of diabetes
Demonstrably glycine positively influences the blood sugar level. The new diabetes research concentrates on this amino acid, too. For example, with glycine supplements the risk of nocturnal hypoglycemia is verifiably significantly lower. Therefore, a supplementation for diabetes type 2 patients is advisable. This might be helpful in improving insulin sensitivity of the cells.
Application as “fountain of youth”
A publication in “Science Daily” in 2015 attracted attention. US-scientists discovered that the difference between a young and an old human cell are not defect DNA-sections. According to this publication the difference is that old cells kind of “switched off” certain genes responsible for an adequate work of the mitochondria. These genes also regulate glycine-production in the cells. After adding glycine into the cell medium no difference between young and old cells were recognizable.
Application as natural “sedative”
Glycine also effects as inhibitory neurotransmitter at glycine receptors in the spinal cord and brain stem. Thus, it has a muscle-releasing and relaxing effect. Furthermore, glycine is able to inhibit resp. reduce the signals of the central nervous system. Thus, it improves concentration and has a calming effect. The release of noradrenaline in the brain is reduced as well as the activity of hyperactive nerves becomes damped.
“Sleep neurons” reacting on glycine are able to turn off sensory stimuli like hearing and smelling. This improves overall sleeping quality. People with problems to fall asleep or to sleep through possibly suffer under a lack of glycine. A well-balanced diet prevents from a lack. It is advisable to supplement glycine when already suffering under arthrosis, diabetes or sleep disturbances.
