Can You Take Iron and Vitamin C Together?
Yes. Vitamin C can improve the absorption of nonheme iron.
The short answer
Iron and vitamin C can be taken together, and vitamin C can help the body absorb some forms of iron.
Why it happens
Vitamin C improves absorption of nonheme iron, the main form in plant foods and many oral iron products.
What to do
They can be taken together; no spacing is required. If iron was prescribed, follow your clinician's and product's directions.
When this advice applies
If you have hemochromatosis, iron overload, or unusually high ferritin, do not combine high-dose vitamin C with iron unless your clinician advises it.
