Can You Take Fish Oil (Omega-3) and Omega-9 Together?

May affect absorption

The short answer

Omega-9 (oleic acid) and Fish Oil compete for intestinal lipid absorption via micelle formation. Large doses of both fatty acid supplements taken together may reduce the absorption efficiency of each.

How to arrange timing

Separate Omega-9 and Fish Oil by at least 1 hour for optimal absorption.

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.
