| Glycine is a conditionally essential amino acid that serves as an
inhibitory and excitatory neurotransmitter. It is the chemically
simplest and most ubiquitous of all the amino acids and combines
with many toxic substances,
converting them to harmless forms which are then excreted.
This amino acid has a calming effect on the brain and is also involved
in growth.127-148* Research
suggests that glycine may help promote deeper sleep, faster, without the “morning
hangover” effect
associated with prescription or over the counter sleep medication.149,150 Glycine also has a positive impact on attention and memory in adults.151,152*
Glycine may also have bacteria regulating effects.
Most people need to take between one to three grams of glycine to be
effective. However, most glycine products are only available in
500 milligram capsules, which make taking higher doses cumbersome and
costly. However, Life Extension’s glycine comes in either 1000 mg easy-to-swallow
capsules or in powder form. |
