Can You Take Iron and PABA Together?
May affect absorption
The short answer
PABA (para-aminobenzoic acid) may chelate iron in the gastrointestinal tract due to its aromatic amine structure, reducing the absorption of both supplements when taken concurrently.
How to arrange timing
Space PABA and iron supplements at least 2 hours apart.

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.
