What we found

Real, repeated independent testing

The International Fish Oil Standards (IFOS) program has repeatedly given Nordic Naturals' Ultimate Omega line its top 5-star rating across purity, potency, freshness, and label-accuracy categories, over multiple testing cycles — and the brand publishes batch-specific Certificates of Analysis publicly, so you can check the actual lot you're buying rather than taking a general claim on faith.

A recognized pioneer brand, not a newcomer

Nordic Naturals was founded in 1995 by Joar Opheim and is headquartered in Watsonville, California — a privately held, well-established company widely recognized as one of the category's original brands, not a recent private-label entrant.

The label, in more detail

What's actually in a serving

A standard 2-softgel serving of Ultimate Omega provides 1,280 mg of combined EPA and DHA — 650 mg EPA and 450 mg DHA. Nordic Naturals also sells a more concentrated "2X" version of this product delivering 2,150 mg of total omega-3 per serving. That's worth knowing about if you're comparing sizes while shopping — it's a different, more potent variant of the same line, not the standard formula reviewed here.

Who should talk to a doctor first

Blood thinners and fish oil

Fish oil can potentiate anticoagulant and antiplatelet medications like warfarin, particularly at doses above roughly 3g/day — meaningfully more than a standard single serving of this product. People on blood thinners, or with surgery scheduled, should talk to a doctor before adding fish oil. For healthy individuals taking a standard single serving, the sources we reviewed describe the bleeding risk as low.

Common questions

What's the difference between EPA and DHA?

EPA and DHA are the two main omega-3 fatty acids found in fish oil. They're structurally related but the body uses them somewhat differently, and most fish oil supplements, including this one, provide both together rather than isolating just one.

Why does it matter that this is "burpless"?

A fishy aftertaste and "fish burps" are a real, common complaint about fish oil supplements. Some formulations reduce this through enteric coating, specific processing, or flavoring — Nordic Naturals markets this product as a "burpless" formula on that basis. It's a real, practical tolerability point, not a claim about the product's effectiveness.
