Can You Take EPA and Stearidonic Acid (SDA) Together?

Use extra care with this pair

The short answer

Stearidonic Acid (SDA) is an omega-3 that efficiently converts to EPA in the body. Taking both SDA and standalone EPA stacks total EPA availability and amplifies antiplatelet effects.

How to arrange timing

Account for SDA's conversion to EPA when calculating total omega-3 intake. SDA converts to EPA at approximately 20-30% efficiency.

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.
