Omega-3 fatty acids are among the most studied nutrients on the planet, with over 40,000 published research papers supporting their role in heart, brain, joint, and eye health. Yet most Americans still don't get enough. Whether you're new to omega-3 supplements or looking to optimize your intake, this guide covers everything you need to know — from the science behind EPA and DHA to choosing the right product for your health goals.

Your Guide to Omega-3 Fatty Acids
The Three Essential Omega-3s
EPA (Eicosapentaenoic Acid)
The anti-inflammatory powerhouse. EPA is the omega-3 most researched for cardiovascular health, joint comfort, and mood support. Found primarily in fatty fish and concentrated fish oil supplements. The American Heart Association recommends EPA-rich omega-3s for heart health.
DHA (Docosahexaenoic Acid)
The structural building block. DHA makes up 97% of the omega-3 fats in your brain and 93% in your retinas. It's essential for cognitive function, visual acuity, and fetal development during pregnancy. DHA-rich supplements are especially important for brain and eye health.
ALA (Alpha-Linolenic Acid)
The plant-based omega-3. Found in flaxseed, chia seeds, and walnuts, ALA must be converted to EPA and DHA in the body — but conversion rates are only 5-10%. That's why direct sources of EPA and DHA from fish oil or algae are considered more effective for meeting your omega-3 needs.
Why EPA Matters for Your Heart & Joints
EPA (eicosapentaenoic acid) is the omega-3 fatty acid most closely linked to cardiovascular wellness and healthy inflammatory response. Clinical studies show that higher EPA intake supports healthy triglyceride levels, promotes arterial flexibility, and helps maintain comfortable joint function. Our Peak EPA delivers 750mg of EPA in a single softgel — one of the most concentrated EPA formulas available — from 100% wild-caught Alaska Pollock.
Why DHA Matters for Your Brain & Eyes
DHA (docosahexaenoic acid) is the primary structural fat in brain tissue and the retina. Adequate DHA intake is associated with better cognitive performance, sharper vision, and healthy neurological aging. It's also critical during pregnancy and early childhood development, when the brain is growing most rapidly. Our Peak DHA provides 600mg of DHA per serving, specifically formulated for those prioritizing brain and eye health.
Heart Health
EPA and DHA support healthy triglyceride levels, blood pressure, and arterial function — the cornerstones of cardiovascular wellness.
Brain & Cognition
DHA is the dominant fat in brain cell membranes. Omega-3s support memory, focus, and healthy cognitive aging throughout life.
Joint Comfort
EPA's natural anti-inflammatory properties help support joint flexibility, mobility, and comfort — especially with aging or active lifestyles.
Eye & Vision
DHA is concentrated in the retina. Adequate intake supports visual acuity and helps protect against age-related eye concerns.
Prenatal Development
DHA is essential for fetal brain and eye development. Expert guidelines recommend omega-3 supplementation during pregnancy and nursing.
How to Choose the Right Omega-3
Not all omega-3 supplements are created equal. Follow these steps to find the best one for your needs.
1
Identify Your Health Goal
Heart and joints? Look for high EPA. Brain and eyes? Prioritize DHA. General wellness? A balanced EPA+DHA formula works best.
2
Check the EPA & DHA Amounts
Don't just look at "total fish oil" — the number that matters is the combined EPA + DHA per serving. Aim for at least 500mg daily; 1000mg+ for targeted health goals.
3
Consider the Source
Wild-caught fish from clean, sustainable fisheries ensures purity. Look for MSC certification — the gold standard for sustainable seafood — and third-party testing for contaminants.
4
Choose Your Format
Softgels are convenient for daily use. Liquids offer higher potency per serving. Mini softgels are 55% smaller for those who dislike swallowing pills. Gummies offer a plant-based alternative.

Triglyceride vs. Ethyl Ester: Understanding Omega-3 Forms
You may see omega-3 supplements marketed as "triglyceride form" (TG) or "ethyl ester form" (EE). Triglycerides are the natural form found in fish — the way your body has evolved to absorb omega-3 fats. Ethyl esters are a semi-synthetic form created during concentration. While some brands claim TG is vastly superior, clinical research shows both forms are well absorbed and effective when taken with food. Our liquid products are guaranteed 90% triglyceride form for those who prefer the natural molecular structure. What matters most isn't the form — it's the total amount of EPA and DHA you actually consume each day.
Why Our Omega-3s Are Different
Wild-Caught Alaska Pollock
Every product starts with a single species — wild Alaska Pollock from the Bering Sea. No mystery blends. No farmed fish. American-caught by regulated fisheries with some of the strictest sustainability standards in the world.
MSC Certified Sustainable
We hold Marine Stewardship Council certification — the gold standard for sustainable fishing. Only 27 fish oil brands worldwide carry this certification. Our fishery is independently audited to ensure healthy fish populations for generations to come.
NSF Tested & Family Made
Every formula is NSF certified for purity, potency, and label accuracy. We're a family-owned company with 40+ years of omega-3 expertise, manufacturing everything in our own facility in Coshocton, Ohio — not a contract manufacturer.
Omega-3 FAQs
Most health organizations recommend a minimum of 250-500mg combined EPA and DHA daily for general wellness. For specific health goals like heart health or joint support, research often uses 1000-2000mg daily. Our Peak EPA provides 1000mg of omega-3 in just one softgel. Always consult your healthcare provider for personalized dosing.
Fish oil is the source; omega-3s are the active nutrients inside. A fish oil capsule contains a mix of fats, but only the EPA and DHA omega-3 portions provide the researched health benefits. That's why it's important to read the Supplement Facts label for EPA and DHA amounts, not just "total fish oil." Higher concentration means more omega-3 per pill and better value.
The American Heart Association recommends eating fatty fish (salmon, mackerel, sardines) at least twice per week. If you consistently eat 2-3 servings of fatty fish weekly, you may get adequate omega-3s. However, most Americans eat far less than this. Supplementation is an effective way to bridge the gap, especially for those who don't eat fish regularly.
It depends on your primary health goal. EPA is the better choice for heart health, joint comfort, and mood support due to its anti-inflammatory properties. DHA is preferred for brain function, eye health, and during pregnancy for fetal development. For general wellness, a balanced product with both EPA and DHA is ideal. Our Easy Swallow Minis offer a convenient balanced formula.
Alaska Pollock is the largest sustainable fishery in the world, MSC certified, and produces an exceptionally clean oil that concentrates well into high-potency supplements. Unlike krill oil (which delivers very low EPA+DHA per serving), Pollock oil can be concentrated to provide 750mg+ of EPA in a single softgel. Unlike farmed salmon, wild Pollock carries no antibiotic or feed concerns.
Take omega-3 supplements with a meal that contains some fat for best absorption. This is true for both triglyceride and ethyl ester forms. Many people find it easiest to take their omega-3 with breakfast or dinner. Consistency matters more than timing — the key is making it a daily habit.
