Why salmon belongs on your plate — and omega-3 supplements in your routine. Salmon has earned its superfood reputation for good reason: it's one of the richest natural sources of omega-3 fatty acids on the planet. Omega-3s are polyunsaturated fatty acids — often called "the good fats" — and they're among the most extensively studied nutrients in modern nutritional science. There are three main types of omega-3 fatty acids: EPA, DHA, and ALA. Each plays a distinct role in supporting your overall health and wellness.*
What are omega-3 EPA, DHA, and ALA?
Omega-3 EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), and ALA (alpha-linolenic acid) are all polyunsaturated fatty acids classified as essential nutrients — meaning the body cannot produce them on its own, and they must come from food or supplementation. EPA and DHA are considered marine omega-3s because they're primarily found in fatty fish and seafood. ALA is a plant-based omega-3 found in foods like flaxseed, walnuts, and edamame.
EPA — a marine omega-3 for cardiovascular and immune support*
EPA, or eicosapentaenoic acid, is a marine-sourced omega-3 fatty acid found abundantly in cold-water fish like salmon, sardines, and mackerel. Research suggests that EPA may help support healthy triglyceride levels already within a normal range and promote a balanced immune response to inflammation.* EPA is also recognized for its potential role in supporting brain health, particularly during early development.*
DHA — the brain and eye omega-3*
DHA, or docosahexaenoic acid, is perhaps the best-known marine omega-3. It's found in cold-water fish such as salmon, sardines, trout, and tuna, as well as shellfish like clams and mussels. DHA is also naturally produced by microalgae — the original source at the base of the marine food chain, and the foundation of OceanBlue's Brain Fuel* formula. DHA is an important structural component of the brain and eyes and is recognized for its role in supporting normal brain function across all stages of life.*
ALA — the plant-based omega-3*
ALA, or alpha-linolenic acid, is the primary plant-based omega-3, found in foods like flaxseed, walnuts, chia seeds, and edamame. The body can convert ALA to EPA, and EPA to DHA, though this process occurs at a limited rate. Like its marine counterparts, ALA is associated with supporting healthy heart and cardiovascular function as part of a balanced diet.*
Essential omega-3 nutrition for everyday cellular health*
Because EPA, DHA, and ALA cannot be synthesized by the body, consistent dietary intake or supplementation is an important part of a well-rounded nutritional routine. Most Americans fall short of recommended omega-3 intake from diet alone, and adding a daily omega-3 supplement is one of the simplest steps you can take to close that gap.
OceanBlue's full line of omega-3 supplements — including our high-potency Omega-3 2100 series and Essentials series — are pure, potent, and palatably priced, so anyone can make omega-3 nutrition a consistent part of their daily wellness routine.*
Frequently asked questions
What's the difference between EPA, DHA, and ALA?
EPA and DHA are marine omega-3s found in fatty fish and seafood; ALA is the plant-based omega-3 found in flaxseed, walnuts, chia, and edamame. The body can convert ALA into EPA and then DHA, but only at a limited rate.
Why are omega-3s called "essential" fatty acids?
Because the body cannot produce them on its own — they must come from food or supplementation.
Which omega-3 is most important for the brain and eyes?
DHA — it's a key structural component of both the brain and the retina, and supports normal brain function across all stages of life.*
Can I get enough omega-3s from diet alone?
Most Americans fall short of recommended omega-3 intake from diet alone. A daily omega-3 supplement is a simple way to help close that gap.*
