What the interaction means

Doxycycline's FDA label documents mineral-type interactions specifically with aluminum, calcium, magnesium, iron, and bismuth subsalicylate -- creatine (an amino-acid-derived compound, not a mineral) is not among them. NCCIH's bodybuilding-supplements page (which covers creatine) does not mention doxycycline.

No documented interaction between Creatine and Doxycycline 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

Doxycycline's FDA label and NCCIH's bodybuilding-supplements page were checked directly, full text, in both directions. Doxycycline's documented mineral-binding interactions are specific to true minerals and do not extend to creatine.
