Can You Take Doxycycline (Low Dose) and Iron Together?
Use extra care with this pair
The short answer
Iron forms insoluble chelates with doxycycline, reducing absorption of both. This is a well-established drug-mineral interaction.
How to arrange timing
Separate low-dose doxycycline from iron supplements by at least 3 hours.

Important context
Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
