Can You Take Calamansi and Iron Together?

May affect absorption

The short answer

Calamansi contains polyphenolic compounds including flavonoids that may chelate iron, reducing absorption of both. However, its vitamin C content may partially offset this effect.

How to arrange timing

Separate Calamansi and iron supplements by at least 2 hours for optimal iron absorption.

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.
