One of my absolute favorite sleep aids is 5-HTP. 5-HTP is the hydroxylated form of tryptophan and easily passes your blood brain barrier when it is converted to serotonin, thereby giving mood a boost and enhancing sleep and then to melatonin.

I believe this is a superior approach to using melatonin. In one study, an amino acid preparation containing both GABA (a calming neurotransmitter) and 5-HTP reduced time to fall asleep, increased the duration of sleep and improved sleep quality.1Sleep — Why You Need It and 50 Ways to Improve It
