5-HTP is the direct precursor to serotonin. Effects are real but should not be combined with SSRIs/MAOIs. Evidence is most established for mild depression and fibromyalgia.
5-HTP showed antidepressant effects in pooled studies, though methodological quality was variable. Effects similar to tricyclic antidepressants in older trials.
5-HTP produced significant improvements in tender points, pain intensity, morning stiffness, sleep, and anxiety vs placebo.
We prioritize randomised controlled trials and meta-analyses over single observational studies. Animal and in-vitro data are listed as "mechanistic", they suggest direction, not human effect size.
We don't cherry-pick favourable studies, omit conflicting evidence, or cite industry-funded trials without flagging the conflict of interest where known.
The research is one thing, what to take, at what dose, paired with what, is another. We compose stacks that turn the evidence into a daily routine.
