What it's actually good for

Mood

Research Supported

Meta-analyses indicate it is more effective than placebo for depressive symptoms.

Sleep

Mixed Evidence

May improve sleep quality and latency, particularly when paired with GABA.

Energy

Not Supported

Often causes drowsiness or lethargy rather than energy.

How it works

5-HTP is a direct precursor to serotonin that bypasses the rate-limiting step of tryptophan hydroxylase. It shows moderate efficacy for improving mood and sleep quality, though long-term use requires caution regarding neurotransmitter balance.

It crosses the blood-brain barrier and is decarboxylated into serotonin, increasing central nervous system serotonin levels.

Safety

  • Risk of serotonin syndrome if combined with SSRIs or MAOIs.
  • Commonly causes nausea or GI distress at doses above 100mg.
  • May deplete dopamine and other catecholamines with chronic use.
