What the interaction means

NCCIH's melatonin page names exactly two classes needing medical supervision -- epilepsy and blood thinner medications -- and probiotics fit neither. NCCIH's probiotics page's only medication-related discussion anywhere is research on reducing antibiotic-associated diarrhea, and does not mention melatonin.

No documented interaction between Melatonin and Probiotics was identified in the authoritative sources reviewed. This is not a guarantee that no interaction exists for every dose, formulation, or individual -- it means the sources checked did not document one.

Practical context

NCCIH's melatonin page and NCCIH's probiotics page were checked directly, full text, in both directions. Probiotics are not an anticoagulant/antiplatelet drug or an epilepsy medication.
