Kesimpulan

5-HTP may support better sleep through its role in serotonin and melatonin production, but human evidence remains limited despite strong preclinical results.

35 out of 42 studies show positive effects on sleep, but most are animal or lab studies
5-HTP is a natural precursor to serotonin and melatonin, key neurotransmitters for sleep regulation
Only 1 randomized controlled trial (RCT) in humans has been conducted
A GABA/5-HTP combination has shown sleep-promoting effects in preclinical models
