Supplement × Supplement·Evidence index
PubMed indexes 3 records that name 5-HTP and SSRIs/SNRIs/MAOIs together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to 5-HTP and SSRIs/SNRIs/MAOIs. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
“Several double-blind studies have shown 5-HTP to be effective in the treatment of nondrug-induced depression. We hypothesize that patients who become depressed on IFN will respond to the synergistic combination of SSRIs plus 5-HTP.”
Names both 5-HTP and SSRIs/SNRIs/MAOIs in its title.
“Low 5-HT function in NMRI mice may account for their insensitivity to SSRIs in the tail suspension test. As the tail suspension test is a predictor of clinical efficacy, the current data suggest that 5-HTP adjunct treatment may benefit SSRI treatment refractory patients.”

Search-based evidence indexes have real limits, and it is worth being explicit about them:
NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers 5-HTP, SSRIs/SNRIs/MAOIs, and several hundred other substances.
The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
NutriStack is an informational and organizational tool, not a medical service, and not a substitute for professional advice. Always consult a qualified healthcare professional before starting, stopping, or changing any supplement or medication.
