Can you take Iron and Curcumin together?
Curcumin has iron-binding properties that can reduce iron availability. Separate them by a couple of hours if you need iron supplementation.
Severity
Caution
Evidence
moderate
Timing
Separate by 2+ hours.
How it works
Curcumin binds ferric iron through its beta-diketone moiety, reducing the pool of free iron available for absorption.
The chelation is dose-dependent and more significant at high curcumin doses. In iron overload conditions, this property is actually considered therapeutic. For people supplementing iron for deficiency, it's a hindrance.
What to do
Take iron and curcumin at different meals. Iron in the morning on an empty stomach, curcumin with a fatty meal later in the day.
