When and how to take 5-HTP
Many people take 5-HTP in the evening, since it supports serotonin and, downstream, melatonin. Taking it with a little food can reduce the nausea some people feel.
Can you take 5-HTP with other supplements?
Do not combine 5-HTP with antidepressants (SSRIs, SNRIs, MAOIs) or other serotonergic drugs without medical supervision — the combination risks too much serotonin.
5-HTP side effects
Nausea is the most common effect, usually mild and eased by taking it with food.
General guidance on timing and absorption, not medical advice. Check with a clinician about your medications and conditions.
