Glycine and growth hormone Increase
This is a nonessential amino acid for which until recently there was little interest, despite decades ago that Dr. Chaikelis showed that consumption of 6g of glycine for ten weeks significantly improved strength in well-trained athletes.
Attention to this amino acid increased when creatine has been boosted ahead of supplements for athletes and has been shown in numerous studies its undoubted effectiveness, since glycine is one of three natural precursors in the formation of creatine, necessary for muscle contractions.
Lack of creatine in the body leads to muscle weakness
The anabolic role of glycine
However, we now know that increases in strength achieved with the administration of glycine probably come from increased production of growth hormone that creatine.
Until recently it had not investigated this course of action because it was thought that only worked in the brain as a neurotransmitter inhibitor, however, the latest research shows that enhances the action of important excitatory amino acids in a brain dots called N-methyl-D- aspartate.
Although the body produces glycine 20g daily, in one study a dose of 6,75g was an increase in growth hormone secretion above average four times. In another conducted in the Brain Bio Center Princeton, by Dr. Carl Pfeifer 30g oral administration produced a rise ten times higher levels of growth hormone.
That does not mean to be similar doses, which are only used in medical studies used, but promising results suggests that athletes can derive anabolic benefits of supplementation with this amino acid.
Use with athletes have been reports that reported a higher dose 15g causes headaches especially its used before training. In lower amounts of between 5-10g can mean a natural adjunct to the optimum production of growth hormone from whose activities are the anabolic character.
Other benefits of Glycine
- Glycine is required for the synthesis of nucleic acids , construction of RNA and DNA and the synthesis of bile acids and other amino acids in the body.
- It acts as an inhibitory neurotransmitter, and works well in the treatment of conditions such as epilepsy, hyperactivity and depression.
- It accumulates in the brain `s pineal gland, which produces the master gland hormone melatonin sleep. Glycine helps create positive changes in brain wave patterns that are associated with REM sleep. Studies show that promotes a deeper sleep.
- Glycine is also found to be useful to help the absorption of calcium in the body.
- It is an amino acid useful for repairing tissues damaged by helping cure.
- Glycine is important in making the body of hormones responsible for an immune system strong.
- It can help in reducing inflammation of the prostate gland when taken in combination with alanine and glutamic acid.
- It helps convert glucose into energy. It also helps regulate blood sugar levels, which will make our energy is much higher than tackling training
- Animal sources: fish, dairy products, meat, cheese, etc.
- Plant sources: legumes, soy, spinach, squash, kale, cabbage, cauliflower, burdock root, cucumber, kiwi, banana, etc.
