For most adults who just want a daily dose of EPA and DHA, Sports Research Triple Strength Omega-3 is the better buy: it packs more omega-3 into a single softgel than Carlson puts in a teaspoon of cod liver oil, it costs less than half as much per day, and it doesn’t need a fridge. Carlson Cod Liver Oil wins a specific and common situation, though. If you’re dosing children, or you’re an adult who can’t face swallowing large capsules, a liquid you can measure by the half-teaspoon is the more practical choice, and Carlson’s is one of the best-verified liquids on the market.

These two products represent the fork in the road most people hit when they go shopping for an omega-3 fatty acids supplement. One is a traditional cod liver oil, taken by the spoon and naturally carrying vitamins A and D. The other is a concentrated fish oil in a capsule, built to deliver as much EPA and DHA as possible with as little fuss as possible. We compared them on dose, cost, the extra vitamins, freshness and sourcing, and convenience.

What the evidence says you’re buying

A reality check first. Large trials haven’t been kind to the idea that fish oil prevents heart disease in healthy people. The VITAL trial, which followed nearly 26,000 US adults, found that a daily 1 g omega-3 supplement did not lower rates of major cardiovascular events or cancer, though a secondary analysis pointed to fewer heart attacks. People take these supplements for many reasons, including low fish intake, eye and brain health, and a doctor’s advice. But neither product here is a heart-disease prevention drug, and you should be skeptical of anyone selling it as one.

Side by side

Dose and cost: Sports Research wins outright

This is the dimension where Carlson simply loses. One Sports Research softgel delivers about 950 mg of EPA and DHA from a 1,250 mg capsule. The 180-count bottle at Walmart has been selling for around $55, which works out to roughly 31 cents a day. Carlson’s teaspoon delivers 870 mg for about 72 cents at the 500 mL list price, or less on Carlson’s own subscription. Per milligram of EPA and DHA, the capsule costs well under half as much.

The balance of the two fatty acids differs too. Sports Research is EPA-heavy, while Carlson leans toward DHA, with 500 mg per teaspoon. There’s no settled answer on which ratio is better for general health, so for most people this is a wash rather than a reason to choose one or the other.

The extra vitamins: a benefit that needs managing

Cod liver oil’s natural vitamin A and D content is its oldest selling point. Carlson’s teaspoon includes 400 IU of vitamin D3, half the adult daily value, which is useful for people who get little sun. The NIH’s vitamin D fact sheet sets the recommended intake at 600 IU for most adults and children, so a teaspoon covers a good share of it.

The vitamin A is the part to keep an eye on. At 850 IU a teaspoon, it’s well within safe limits for an adult taking one serving. But it means you can’t double or triple your cod liver oil to chase a higher omega-3 dose the way you might with capsules, and you should total it against any multivitamin you take. Sports Research contains no added vitamins, so there’s nothing to add up. For adults who want high-dose EPA and DHA and nothing else, that simplicity is a point in its favor.

Freshness and sourcing: close, with different strengths

On testing, there’s little to separate them. Both carry IFOS certification, and Carlson adds its own potency and purity testing in an FDA-registered lab. Purity isn’t what should decide this one.

On sustainability, Sports Research has the cleaner label story. Its Alaska pollock comes from an MSC-certified fishery. Carlson describes its Norwegian Arctic cod as sustainably sourced, but Northeast Arctic cod’s MSC status has been complicated: after a 2021 objection over redfish bycatch, the offshore Norwegian fishery was certified while the inshore fishery lost its certificate. If an ecolabel on the bottle matters to you, the capsule is the easier choice.

Convenience: depends entirely on who’s taking it

For an adult who swallows pills easily, the softgel wins. It sits in a drawer, travels well, and Sports Research markets it as burpless. Carlson has to go in the fridge once opened and is meant to be used up within a few months.

For everyone else, the liquid is the better tool. Softgels this size are large, and a lot of people, children especially, can’t or won’t swallow them. Carlson’s liquid cod liver oil comes in lemon, green apple, and fruit splash versions precisely so a teaspoon can go down straight or stirred into a smoothie or juice. And you can measure a half-teaspoon or less for a child, which you can’t do with a capsule. There’s also an unflavored version for parents who’d rather hide it in food than argue about taste.

Which one fits your household

If you’re an adult who wants the most EPA and DHA for your money and has no trouble with capsules, Sports Research Triple Strength is the stronger choice. It’s cheaper per milligram, it needs no refrigeration, and there are no vitamins to track.

If the omega-3 is for your kids, or for anyone in the house who gags on softgels, choose Carlson. You’ll pay more per milligram, and you’ll need fridge space, but you get a well-tested liquid you can dose precisely in a flavor people will take, with a useful amount of vitamin D included. That’s a real advantage, not a consolation prize, because a supplement nobody takes costs more than any other.
