Omega-3: EPA, DHA and What to Look For

Omega-3 fatty acids EPA and DHA are found mainly in fatty fish and marine oils. They are involved in cell membranes and several physiological processes.
What the evidence suggests
Regular fish intake is associated with cardiovascular benefits, and EPA/DHA supplementation can be useful for people who eat little oily fish or when a clinician recommends it for a specific reason. The required amount depends on the goal.
How to use it in practice
When comparing fish-oil products, focus on the combined EPA and DHA content rather than the total 1,000 mg or 1,500 mg oil number on the front label.
What to check on the label
- Find the exact EPA and DHA amount per daily serving.
- Check storage instructions and product quality because oils can oxidize.
- Look for clear fish-allergen information.
Safety and context
Omega-3 supplements can affect bleeding risk at high intakes and may interact with anticoagulant medication. Discuss higher-dose use with a clinician.
