Can You Take Vitamin B2 and Iron Together?

May affect absorption

The short answer

Riboflavin (B2) enhances iron absorption and is required for iron mobilization from ferritin stores. However, concurrent high-dose supplementation may cause GI discomfort.

How to arrange timing

Can be taken together at moderate doses; separate by 1 hour at high doses.
