Improve your sleep with glycine, and your memory will work better too
Glycine
Gelatin for example consists of 22-25 percent glycine. If you want to consume 3 g glycine, and don't have glycine supplements available, then 12-14 g gelatin would do the trick.
Animal studies have shown that glycine supplementation is safe. The LD50 – the single dose at which half of a group of rats dies – is 7.9 g glycine per kg bodyweight. That's high.
Study
The next day the participants reported that they had slept better after taking the glycine supplement. To put it more precisely: the subjects felt they had fallen asleep more quickly and had woken less often during the night after taking glycine. During the day following a night of glycine-aided rest, the subjects felt more alert.
Results
The researchers also discovered that the glycine-enhanced sleep also led to an improvement in memory function. The subjects were given a test in which they had to remember letters or numbers that they had seen previously on a computer screen.
Conclusion
"Therefore there is a need for a safe and reliable sleep regulator for those occasions when sleep is disturbed. Our present results suggest that glycine produces subjective and objective improvement of sleep quality and leads to a natural sleep pattern, including an early appearance of slow wave sleep and maintenance of REM sleep."
