OceanBlue Professional Omega-3 2100 with K2 & D3 Review: One Softgel for Heart, Bone, and Immune Support

If you have ever taken fish oil and spent the afternoon fighting fishy burps, the OceanBlue Professional Omega-3 2100 with Vitamin K2 & D3 wants your attention. It also targets a second headache: juggling three separate bottles to cover your omega-3, your vitamin D3, and your vitamin K2.

This is a wild-caught fish oil in an orange-flavored softgel that folds a triple-strength dose of omega-3 fatty acids together with two partner nutrients most fish oils leave out. You get 60 softgels, a 30-day supply at the recommended two per day.

Each serving delivers 2,100 mg of omega-3, made up of 1,350 mg EPA, 600 mg DHA, and 150 mg DPA, plus 150 mcg of K2 and 2,000 IU of D3. I went through the bottle, the label, and the softgels themselves to see whether the all-in-one pitch holds up.

The one thing that surprised me was how little these actually smell, which I will get to below. Here is my full breakdown of the OceanBlue Omega-3 2100: what stands out, where it falls short, and who should skip it.

What I Liked

Most of what won me over comes down to how much this single softgel is doing at once, and how easy the brand makes it to take.

Triple-strength 2,100 mg omega-3 dose in every serving

The headline number is the potency. OceanBlue packs 2,100 mg of omega-3 into a two-softgel serving, with 1,350 mg of EPA and 600 mg of DHA doing the heavy lifting. The brand describes it as roughly three times more potent than standard fish oil at an 85% pure concentration, and that EPA-heavy ratio is well suited to heart, circulation, and joint support.

DPA rounds out a more complete omega-3 profile

This is the part that sets the OceanBlue Omega-3 2100 apart from a typical two-ingredient fish oil. Each serving adds 150 mg of DPA, the third omega-3 that most supplements skip entirely. OceanBlue calls it the “missing link,” and it works alongside EPA and DHA to support metabolic health, so you get a fuller fatty acid profile than the usual EPA and DHA pairing.

Vitamin K2 and D3 built into the same daily softgel

Folding 150 mcg of vitamin K2 and 2,000 IU of vitamin D3 into the same capsule is the real convenience win. D3 supports bone strength and immune function, while K2 helps direct calcium toward your bones, and the two work as a team. Finding that omega-3, D3, and K2 combination in one fish oil is genuinely hard, so it replaces a small stack of separate pills.

Burpless orange formula with almost no fishy smell

The burpless claim is the one I was most skeptical about, and it mostly held up. When I smelled inside the bottle there was a faint orange-and-fish note, but the individual softgel gave off almost nothing beyond a slight hint of orange. That mild profile is exactly what you want if the fishy aftertaste has scared you off fish oil before.

Third-party tested, wild-caught, and Friend of the Sea certified

The quality signals are reassuring for a supplement you take daily. The oil is wild-caught and certified sustainable by Friend of the Sea, it is non-GMO, and the brand says every batch is tested to be free of heavy metals and contaminants. That testing matters more with fish oil than with almost any other supplement.

What Needs Improvement

No supplement is perfect, and a few things keep the OceanBlue Omega-3 2100 from being a universal pick.

Fishy burps still slip through for some users

The burpless technology works for most people, but it is not absolute. In Amazon’s aggregated feedback, 9 of 21 shoppers who mentioned burp resistance reported fishy burps anyway, sometimes even when taking the softgels with food. My own experience was clean, yet this is clearly hit or miss depending on your digestion.

Large softgels are tough if you dislike pills

These are standard fish oil softgels, which means they are on the bigger side. The brand does not shrink them down, so if you already struggle to swallow capsules, these will not change your mind. It is the single most common reason someone should look elsewhere.

Softgels can clump together in hot-weather shipping

A recurring note in customer reviews is that the softgels can arrive stuck together in a clump when they ship through summer heat. It is a packaging and transit issue rather than a formula flaw, but it can be frustrating to open a new bottle to fused capsules. Storing them somewhere cool once they arrive helps.

Priced above basic drugstore fish oil brands

At its list price the OceanBlue Omega-3 2100 costs more per bottle than budget drugstore fish oil. The concentration and added vitamins justify a lot of that gap, but the sticker still runs higher than a bare-bones EPA and DHA product. Shoppers chasing the lowest cost per serving will feel it.

How It Compares

The omega-3 aisle is crowded, so it helps to see where this OceanBlue fish oil lands against the products people cross-shop most.

Against Nordic Naturals Ultimate Omega, the difference is dose and profile. Nordic Naturals is the brand dietitians recommend most, but Ultimate Omega delivers roughly 1,280 mg of total omega-3s per serving and contains no DPA. OceanBlue’s 2,100 mg per serving is a meaningfully higher concentration, and the DPA plus the built-in K2 and D3 give it a wider job description.

Against Dr. Tobias Omega-3, it comes down to what you value. Dr. Tobias is a budget favorite with a strong EPA and DHA count, but it skips DPA and the added vitamins. If you only want cheap EPA and DHA, Dr. Tobias makes sense; if the all-in-one profile matters, the OceanBlue Omega-3 2100 earns its premium.

Against a standard drugstore fish oil like Nature Made, it is not close on potency. Most retail fish oil supplies only 300 to 500 mg of omega-3s per serving, so you would need about three of those pills to match one OceanBlue serving. That is the “replace three bottles with one” pitch in a nutshell, and it holds up across both the video and the customer reviews I read.

Final Verdict

After going through the label, the softgels, and the wider feedback, the OceanBlue Professional Omega-3 2100 with Vitamin K2 & D3 is an omega-3 I would recommend checking out. It earns a 4.2 out of 5 in my book.

The appeal is the all-in-one design. You get a high-potency, wild-caught formula with DPA in the mix and vitamin K2 and D3 baked in, which covers heart, bone, joint, and immune support without choking down three separate bottles. The burpless orange approach makes it a gentler daily habit than the fish oil most of us grew up avoiding.

The caveats are honest ones rather than dealbreakers. The softgels are large, a minority of users still get fishy burps, and the price sits above bare-bones brands. None of that undercuts the core value if the combined profile is what you are after.

If you want triple-strength omega-3 plus D3 and K2 in one softgel and you can handle a standard-size pill, this belongs in your supplement routine. If swallowing capsules is a struggle or you only want the cheapest EPA and DHA, a simpler product will serve you better.
