Here is something that surprised me when I started researching omega-3 supplements. Fish oil oxidizes. When fish oil is exposed to heat, light, or air it goes rancid, and rancid fish oil not only smells bad and tastes bad, it may actually be harmful rather than beneficial. Studies have found that a significant percentage of fish oil supplements on store shelves exceed recommended oxidation limits.
Nordic Naturals tests every single batch for oxidation levels and purity, and they make those results publicly available. When I found that out, it made it very easy to decide which omega-3 supplement I was going to use.
Not all fish oil capsules are created equal in terms of active ingredient content. A 1000 milligram fish oil softgel typically contains around 300 milligrams of combined EPA and DHA, the actual active omega-3 fatty acids that provide the health benefits. The rest is other fats.
Nordic Naturals Ultimate Omega provides 1280 milligrams of EPA and DHA combined per two-softgel serving. That is a meaningful and effective dose. Many cheaper fish oils would require you to take five or six capsules to match that amount, negating the cost advantage quickly.
Fishy aftertaste and fish burps are the main complaint people have with omega-3 supplements, and they are usually a sign of oxidation. Fresh, high-quality fish oil should taste like lemons, not fish. Nordic Naturals uses a lemon flavor and their oxidation standards help ensure the oil stays fresh. In my experience with this product the fishy burp problem is minimal compared to lower quality options.
Omega-3 fatty acids are among the most researched nutrients in existence. EPA and DHA support heart health, brain function, joint health, and reduce inflammation throughout the body. The benefits are real and well documented. The key is taking them consistently and getting them from a product that is actually fresh and not oxidized, which is exactly what Nordic Naturals delivers.
Honestly, most people. Unless you are eating fatty fish like salmon, sardines, or mackerel three or more times per week, you are probably not getting enough EPA and DHA from diet alone. Omega-3 supplementation is one of the foundational recommendations I give to almost everyone regardless of their fitness goals.
