Best Omega-3 Supplements Of 2026

• ALA (alpha-linolenic acid): An essential fat found in plant foods like flaxseed, chia seeds, and walnuts. Your body can't make ALA, so you need to get it from your diet.
• EPA (eicosapentaenoic acid): Found mainly in fatty fish and seafood, EPA is best known for supporting heart, brain, and mood health.*
• DHA (docosahexaenoic acid): Also found in marine foods (and algae), DHA is a major structural component of the brain and eyes and plays an important role throughout life.*

While all three omega-3s are important, most of the health benefits associated with omega-3 supplements come from EPA and DHA. Your body can make small amounts of these fats from ALA, but the conversion is very limited. That's why omega-3 intake (and supplementation) is so important. 

• Heart health: EPA and DHA help support healthy cholesterol, triglyceride levels, and overall heart function.*
• Brain and cognitive health: DHA is a major building block of the brain, while both EPA and DHA support healthy cognitive function.*
• Eye health: DHA is highly concentrated in the retina and helps maintain healthy vision.*
• Joint mobility: Omega-3s help support a healthy inflammatory response, promoting joint comfort and mobility3.*
• Mood and mental well-being: Research suggests EPA and DHA help support a balanced mood and emotional well-being3.*
• Pregnancy and early development: Omega-3s, especially DHA, are important for healthy fetal brain and eye development during pregnancy.*

Because so few people consume enough omega-3-rich seafood, a high-quality fish oil or algae-based supplement can be a simple way to help close the gap and support whole-body health.*

• People who rarely eat seafood: If you rarely eat seafood, then an omega-3 supplement should absolutely be on your radar. Even if you eat fatty fish multiple times a week, a supplement is still a smart choice for getting a therapeutic amount of these nutrients on a daily basis. 
• Vegetarians and vegans: Algae-based omega-3 supplements provide DHA (and in some cases EPA) without using fish.
• Adults looking to support heart and brain health: EPA and DHA help support cardiovascular function, cognitive health, and healthy aging.*
• People who are pregnant or trying to conceive: DHA plays an important role in fetal brain and eye development, making it an important nutrient during pregnancy.* If you’re pregnant, breastfeeding, or preparing for pregnancy, talk with your healthcare provider before to determine the right option and dose for you.
• Active individuals and older adults: Omega-3s help support a healthy inflammatory response and joint mobility, making them a valuable addition to many wellness routines.*

If you have a medical condition, take blood-thinning medication, it's always a good idea to check with your healthcare provider before starting any new supplement.

• EPA and DHA: Choose a supplement that clearly lists its EPA and DHA content. Most experts recommend at least 500 milligrams of combined EPA and DHA daily.
• Quality sourcing: Look for sustainably sourced fish or algae, along with third-party testing for purity and freshness.
• Absorption: Triglyceride-form omega-3s are generally absorbed best, though ethyl ester forms can also be effective when taken with a meal.
• Simple ingredients: The best formulas contain few unnecessary additives and use ingredients that help keep the oil fresh and improve taste.
