FOS and iron can be taken together. FOS may enhance iron absorption through gut fermentation.

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.
