Glycine calms the nervous system, reduces stress and promotes relaxation, which can improve the quality of sleep, the time it takes to fall asleep and daytime tiredness. L-arginine detoxifies and protects cells from harmful breakdown products, which promotes peaceful and undisturbed sleep

Yet another alternative.

Taking L-tryptophan helps improve sleep because it increases melatonin and serotonin, which harmoniously regulate the human sleep-wake rhythm. Numerous research results show that L-tryptophan can help improve the quality of sleep in people of all ages.

That's the major reason I stopped taking melatonin. I didn't want to stop producing it naturally
