Omega-3 Fish Oil: EPA, DHA and How to Choose

Omega-3 fatty acids, especially EPA and DHA, are among the most widely studied nutrients. Most people get them from fatty fish such as salmon, sardines and mackerel. If you don’t eat fish often, a fish-oil supplement is a simple way to add EPA and DHA to your routine.

What EPA and DHA do

EPA and DHA are long-chain omega-3s. They are part of the membranes of every cell, and DHA is concentrated in the brain and eyes. Omega-3s support normal heart health, brain function and overall wellness as part of a balanced diet.*

How to choose a fish-oil supplement

  • Check EPA + DHA per serving, not just total fish oil. The omega-3 content is what matters.
  • Pick a format you’ll take daily: softgels give the most omega-3 per serving; gummies are easier for people who dislike swallowing capsules.
  • Allergies: fish-oil products contain fish. Choose an algae-based source if you avoid fish.
  • Medications: talk to your doctor first if you take blood thinners or have a scheduled surgery.
