Can You Take Creatine and Melatonin Together?
No documented interaction was identified between melatonin and creatine in the sources reviewed.
See the full Creatine page and Melatonin page for other reviewed interactions and reference information.
What the interaction means
NCCIH's melatonin page names exactly two classes needing medical supervision -- epilepsy and blood thinner medications -- and creatine fits neither. NCCIH's bodybuilding-supplements page (which covers creatine) does not mention melatonin.
No documented interaction between Creatine and Melatonin 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 bodybuilding-supplements page were checked directly, full text, in both directions. Creatine is not an anticoagulant/antiplatelet drug or an epilepsy medication, so melatonin's two named caution classes do not apply.
