See the offer Best 5-HTP for mood
5-HTP is a serotonin precursor taken for low mood and sleep. Below, the 5-htp products people use ranked by real cost per dose (to the commonly-studied 100 mg dose). A value comparison, not medical advice.
Updated September 2026
What the evidence actually shows
Limited and low-quality — a few small trials hint at an antidepressant effect, but the evidence is weak. Critically, it can interact dangerously with SSRIs/SNRIs and other serotonergic drugs (serotonin syndrome). Do not combine with antidepressants; talk to a doctor first.
Commonly used: commonly 50–100 mg; unsafe with serotonergic medication.
How this list is built: these are 5-htp products ranked by real cost per dose across our whole 5-htp catalogue — not filtered or re-ordered by mood. We don’t hold per-product evidence for a specific use, so we don’t pretend to rank for one. Products whose own label says they are for something else are left out.
