Category: Krill Oil 101

Usually not. “Triple strength” is not a defined or regulated term, and the big number on the front of a krill oil box — 500 mg, 1,200 mg, 1,600 mg, 2,000 mg — is the weight of the krill oil in a serving, not the amount of omega-3 that reaches you. Where both numbers are published, the EPA and DHA you actually swallow runs somewhere between a fifth and a quarter of the number on the front.

Here is the part that should annoy you. Ranking krill oils by the front-of-box number can put them in exactly the wrong order. One of the current best-sellers labelled “Triple Strength 1,600 mg” delivers less omega-3 per softgel than an ordinary competitor labelled 1,200 mg. Same category, same shelf, and the bigger number is the weaker capsule.

What the number on the front actually measures

Krill oil is a whole natural oil, not a concentrate. Pressed out of the krill, it is mostly phospholipids and other fats, with EPA and DHA riding along inside them, plus the astaxanthin that makes it red. The omega-3 you care about is a minority passenger in that oil — not the oil itself.

So “1,000 mg krill oil” means one thousand milligrams of that whole oil. It is an honest number about the wrong thing, the way “16 oz of coffee” tells you nothing about the caffeine.

Then there is the serving-size move. Most of the four-figure numbers on this shelf are per serving, and the serving is two softgels. A bottle shouting 2,000 mg is very often two 1,000 mg capsules. That is legal and normal: FDA’s supplement labelling rule, 21 CFR 101.36, requires the Supplement Facts panel to declare everything on a per-serving basis, and the manufacturer chooses the serving. The front of the box is marketing. The panel on the back is the regulated part, and it is the only part worth reading.

The same comparison, on real bottles

We pulled the published label figures for krill oils currently sitting in the top ten of the “krill oil” search on Amazon. These are their own numbers, not ours:

Read the last column again. The “Triple Strength 1,600 mg” softgel carries roughly 40% less omega-3 than the plain 1,200 mg softgel next to it. Nothing was faked to get there — the 1,600 mg is a two-capsule serving and the 1,200 mg is one. The front numbers simply aren’t measuring the same thing, so comparing them tells you nothing.

And the biggest number on the page, “Maximum Strength 2,000 mg,” doesn’t publish an EPA and DHA figure in its listing copy at all. That’s the second finding, and it’s the more common one: on this shelf, the products with the loudest strength language are frequently the ones that never state the number that would let you check it.

The blends are a category of their own. MegaRed’s 4-in-1, a long-running best-seller here, describes itself as a combination of concentrated fish oil and krill oil in a proprietary blend — so the krill share of that omega-3 isn’t broken out anywhere. ConsumerLab has made the same point bluntly in its omega-3 review: some products sold as “krill oil” are blends of fish and krill oils, and the labelling is misleading.

Three more places the number goes soft

What’s in the capsule isn’t always what’s on the label. In ConsumerLab’s testing of 18 popular omega-3 supplements, four contained 20% to 30% less EPA, DHA or other omega-3s than claimed. Not most of them — but one in five is enough that the printed figure is a starting point, not a guarantee.

“Percent phospholipids” is a composition, not a dose. You’ll see listings advertising 56% phospholipids as a strength claim. Commercial krill oils genuinely range from roughly 39% to 81% phospholipids depending on the krill and the processing, so the figure is real — it just describes the shape of the oil, not how much omega-3 is in your hand.

“Triple strength,” “maximum strength,” “advanced” — none of these mean anything. There is no regulatory definition of any of them, no reference product they’re triple of, and no test you could run to fail one. They’re adjectives.

So what number should you actually use?

One number: milligrams of EPA plus DHA per day. That is the figure trials are run on, the figure your blood work responds to, and the figure that lets you compare a krill oil to a fish oil to a can of sardines on the same scale. If a label won’t give it to you, that’s an answer too. We walk through the ranges people actually target in how much krill oil to take a day.

Do that arithmetic and one uncomfortable thing falls out immediately. A single ordinary 1,000 mg fish oil softgel typically carries around 300 mg of EPA and DHA — more than that entire “triple strength” krill serving above, for a fraction of the money. If grams of omega-3 are what you’re buying, krill is the expensive way to buy them, and we’ve written that out in full, with the per-dose costs.

The counter-argument for krill is the delivery form, not the dose: its omega-3 comes bound into phospholipids rather than triglycerides, which some small studies suggest is absorbed a bit more efficiently. We think that’s a real effect and a modest one, and we say so in our piece on phospholipid versus triglyceride omega-3s. It is not a multiplier that turns 147 mg into 500.

What our own bottle says — and what it doesn’t

Captains Krill Oil™ says 1,000 mg on the front. Same convention as everyone else: that’s the weight of the krill oil, not the omega-3. We’re not going to pretend our front-of-box number is more virtuous than theirs.

What we will tell you is what sits behind it. Our oil is pressed mechanically on the boat, right after the catch, with no chemicals at any stage — the krill goes from ocean to oil without a factory in the middle. It’s a wild natural catch, so it varies a little lot to lot, the way anything pulled out of the ocean does. We test lots at random and they come back strong, and documentation is available on request. What we will not do is print a locked figure and imply a natural oil hits it every time, because we’d be making it up. Twenty years of doing this one thing, in a small family business, and that’s still the honest description.

Which is also why we’re not going to win a milligram contest. Somebody on that shelf will always print a bigger number.

You might not need us

If you eat fatty fish twice a week — salmon, mackerel, sardines, herring — you’re already covering this and no krill oil is going to improve on it. Buy the fish.

If what you want is grams of EPA and DHA, buy a concentrated fish oil. It’s cheaper per milligram, it’s not close, and anyone selling you krill on dose alone is selling you the wrong bottle.

And if you’re standing in an aisle comparing front-of-box numbers, put ours down too. Turn every bottle over, find EPA plus DHA per serving, divide by the number of softgels in that serving, and buy on that. Some days that math won’t point at us. We’d rather you did it anyway.

Frequently asked questions

Is “triple strength” krill oil a real category?

No. It’s a marketing phrase with no regulatory definition, no reference product it’s triple of, and no test that could verify it. Ignore the adjective and read the Supplement Facts panel, which is the part the FDA actually governs.

How much EPA and DHA is in 1,000 mg of krill oil?

Across published labels it typically lands somewhere around 100 to 250 mg of EPA and DHA combined per 1,000 mg of krill oil. It varies by product, by processing, and by the krill itself, which is why the panel on the back is the only place to get the number for the bottle in your hand.

Is 2,000 mg of krill oil better than 1,000 mg?

Only if it’s genuinely more oil, and often it isn’t — a 2,000 mg claim is usually a two-softgel serving of 1,000 mg capsules. Compare per softgel, or better, compare EPA plus DHA per day.

Why don’t some krill oil labels list EPA and DHA?

They generally do somewhere on the panel, but plenty of listings and front labels omit it, and blends of fish and krill oil sometimes fold it into a proprietary blend where the krill share can’t be separated. Treat a missing EPA and DHA figure as information about the seller.

Should I just buy fish oil instead?

If your goal is the most omega-3 per dollar, yes, and we’ll say that plainly. People choose krill for the phospholipid form, the astaxanthin that comes with it, and easier tolerability — not for raw dose. If those aren’t reasons you care about, fish oil is the rational buy.

Krill oil costs three to eight times more than fish oil for the same amount of EPA and DHA, and most of that gap is real production cost, not margin. A little of it is a premium you are paying for the phospholipid form and the sourcing — and whether that part is worth it depends entirely on you, which is the honest part of this answer that most krill pages skip.

We sell Captains Krill Oil™, and by the numbers below we are the most expensive krill oil per softgel in the entire Amazon search for “krill oil.” Take this as a breakdown from someone with a stake in it, and check the math yourself.

First, the number that actually matters

Not the sticker price. Not the price per capsule. The price per gram of omega-3. ConsumerLab has run that comparison across the category, and their figure is the clearest one published anywhere: the cost of 500 mg of EPA plus DHA ranged from 16 to 56 cents for fish oil, 48 to 61 cents for algal oil, and $1.38 to $2.60 for krill oil (ConsumerLab fish, krill and algal oil review). That is roughly a 4× to 8× spread at the midpoints, and it holds up across brands.

The reason is arithmetic no bottle explains. A 1,000 mg fish oil softgel typically carries around 300 mg of EPA plus DHA. A 1,000 mg krill oil softgel typically carries somewhere in the range of 100–200 mg. Krill oil is not a concentrate — it is a whole natural oil, phospholipids and astaxanthin and all, and the omega-3 fraction of it is smaller. You are buying a smaller slice of the molecule you came for, in a more expensive package.

If your only goal is grams of EPA and DHA at the lowest cost, fish oil wins that contest and it is not close. We would rather say that plainly than let you find it out from a competitor.

Reason one: the yield is genuinely terrible

A single Antarctic krill weighs about a gram, and the oil you can actually recover is a fraction of that. Published processing work puts the yield at a startlingly low share of the landed catch — neutral-lipid krill oil off conventional meal plants has been reported at 0.1–0.4% of raw krill during the fatty season (Xie et al., Journal of Food Science, 2018). Even generous methods run on already-concentrated meal land in the teens.

To fill a bottle you are moving a great deal of biomass a very long way. Anchovy oil, by comparison, comes off a fish that is mostly oil, caught a short run from a processing plant. The raw material has a bad ratio and always will.

Reason two: krill begins destroying itself within minutes of coming aboard

This is the cost driver almost nobody outside the industry knows about, and it is the one we care most about.

Krill carry unusually aggressive digestive enzymes. The moment they die, those lipases and proteases release into the animal and start breaking it down — a process called autolysis, and it is fast. Worse, fluoride concentrated in the shell begins migrating into the flesh at the same time. The industrial patent literature is blunt about the window: the time from decking the catch to initial processing “should preferably not exceed 60 minutes, more preferred not exceed 30 minutes, even more preferred not exceed 15 minutes.”

You cannot fix that with logistics. You cannot freeze it fast enough at scale and you certainly cannot ship it anywhere. So every krill operation on earth has to carry its factory to Antarctica — a vessel that is a fishing boat and a processing plant at once, running crew, fuel and maintenance in the Southern Ocean, where weather takes days off the calendar whenever it feels like it. Analysts describe the krill fishery as an asset-constrained business with a high fixed cost per tonne landed: lose fishing days, and cost per tonne climbs whether or not anything downstream went wrong. New Antarctic krill vessels have been funded at figures in the hundreds of millions apiece. That capital, and the fuel burned getting there, gets amortised into your bottle.

Here is where we have skin in it. Captains is mechanically pressed on the boat, right after the catch — no solvents, no chemical wash, no shipping raw krill meal across the world to be reprocessed months later. That is not romance, it is the same clock. Most of the category solves the problem by making meal at sea and extracting the oil later using a solvent on land, which is cheaper and gets a higher yield. We do the more expensive thing on purpose, and the price reflects it.

Reason three: the fishery is capped, and in 2025 it hit the cap

Antarctic krill is regulated by CCAMLR, and Area 48 — where essentially all commercial krill comes from — carries a trigger level of 620,000 tonnes. In 2025 the catch reached that trigger for the first time and the fishery closed early, on 1 August (CCAMLR Fishery Report 2025, Euphausia superba in Area 48).

Be careful how you read that, because both sides overstate it. The trigger is not a scientific maximum — it is a precautionary ceiling set at roughly 11% of the calculated precautionary catch limit of about 5.61 million tonnes. The krill are not running out. But the supply of legally harvestable krill now has a hard annual lid, and demand keeps growing. A capped supply with rising demand does exactly one thing to price.

What we found when we priced the whole category

On 28 July 2026 we scanned all 62 organic and sponsored listings on the Amazon search for “krill oil” and converted each to price per softgel. Nobody publishes this, so here it is.

The volume brands run roughly $0.08 to $0.73 per softgel. Captains sits at $1.00 — the ceiling of the entire search. The only listing that matched us was Stonehenge Health, also at $1.00 a softgel, with 700+ units bought that month.

The more useful finding was in the sponsored rail: the highest sticker prices on the page were among the cheapest per dose. A $148 listing worked out to $0.41 per softgel across a 360-count bundle. A $109.95 listing came to $0.30 across 365 count. Big scary number, small unit price. We got this wrong on the first pass and had to correct it the same day.

So: divide by the softgel count, then by the EPA and DHA per softgel, before you believe anything about price — including this page.

What you are not paying for

Some of the price of premium krill oil is not production cost at all. Amazon fees, sponsored placement and marketing spend are all in the number, and the category carries a “premium supplement” halo that lets it price above what the chemistry justifies.

You are also not paying for factory precision. Captains is a natural raw product — the EPA and DHA vary a little lot to lot, the way a natural catch does. We test lots at random and they come back strong, and documentation is available on request. We do not blend or engineer the oil to hit a chosen number, because that is the factory move and we are not a factory.

You might not need us

Three cases where the money is better spent elsewhere, and we mean this.

If you eat fatty fish twice a week — sardines, mackerel, salmon, herring — you are already getting more EPA and DHA than a krill capsule delivers, for less money and with the protein thrown in. Skip supplements entirely.

If you are dosing for a target and need grams of omega-3, not milligrams, buy a good concentrated fish oil. Getting to 2–3 grams a day on krill is expensive and there is no clever way around it. Our own dosing guide says the same thing.

If the appeal was purely the phospholipid form, read the evidence first. The absorption advantage is real in the sense that it has been measured, but the studies are small and the effect is modest — we lay out what they do and do not show in phospholipid vs. triglyceride omega-3s. It is a reason to prefer krill, not a reason to pay eight times the price if money is tight.

The honest case for paying more is narrow: you want a whole natural marine oil rather than a concentrate, you care how it was pulled out of the animal, and you would rather take a smaller dose you will actually keep taking. That is a real reason, but it is not everyone’s. For the comparison against the other traditional option, we wrote krill oil vs. cod liver oil.

We have been at this twenty years. We would rather lose the sale than have you buy a bottle you resent.

Frequently asked questions

Is expensive krill oil better than cheap krill oil?

Sometimes, but price alone tells you very little. What actually separates a good bottle from a bad one is freshness — oxidation levels — and how the oil came out of the animal, and neither of those is printed on the label. A cheap krill oil from a fast-moving retailer can easily be fresher than an expensive one that sat in a warehouse.

Why is krill oil more expensive than fish oil if it has less omega-3?

Because the omega-3 content is not what makes it costly to produce. The cost sits in the yield, the need to process the catch within minutes aboard a vessel in the Southern Ocean, and a capped fishery. Fish oil is made from oily fish landed near cheap processing plants, and it is concentrated afterwards, so a gram of EPA and DHA is far cheaper to deliver.

Will krill oil prices come down?

Not obviously. The 2025 early closure of the Area 48 fishery points the other way, and the fixed costs of Antarctic vessels are not falling. More fleet capacity could increase supply, but the trigger level caps how much of it can be landed, so added capacity mostly means the cap is reached sooner in the season.

Is a cheaper krill oil in a bigger bottle a better deal?

Do the arithmetic before deciding. Divide the price by the softgel count, then check the EPA and DHA per softgel on the supplement facts panel. In our July 2026 scan of the Amazon results, several of the highest-priced listings were among the cheapest per dose because they were large multi-month bundles.

Does Captains cost more than other krill oil?

Yes. In the July 2026 scan we were the highest price per softgel of all 62 listings on the page. We are mechanically pressed on the boat with no solvents, in small lots, by a small family business — that costs more to do and we have not found a way to make it cost less. Whether that is worth it to you is a fair question and we are not going to pretend the answer is automatic.

Honest answer, not a pitch. — captainskrilloil.com

Cod liver oil and krill oil sound like two versions of the same thing. They aren’t. Cod liver oil is really a vitamin product — its headline act is preformed vitamin A and vitamin D, with some omega-3 riding along. Krill oil is a narrow omega-3 product: EPA and DHA, plus the red antioxidant astaxanthin, and no fat-soluble vitamin load at all. So the honest answer isn’t “which is better.” It’s “which gap are you actually filling?”

We sell Captains Krill Oil, so read the rest with that in mind. But we’ll say the unflattering part first: if the thing you’re short on is winter vitamin D, cod liver oil does a job our krill oil simply can’t. Here’s the whole picture, honestly.

They come from different parts of the fish — and it shows

Cod liver oil is pressed from the liver of the cod. The liver is where a fish concentrates fat-soluble vitamins, so the oil comes out loaded with vitamin A (as retinol) and vitamin D, plus a modest amount of omega-3. Krill oil is pressed from Antarctic krill — a whole tiny animal, not an organ — so it carries omega-3 and astaxanthin but essentially none of the vitamin A or D that makes cod liver oil what it is.

That single difference drives everything else. Buy cod liver oil and you’re mostly buying vitamins A and D. Buy krill oil and you’re buying omega-3 in a different chemical vehicle. Confusing the two is how people end up double-dosing one nutrient and missing another entirely.

The vitamin A ceiling nobody mentions

Here’s the part the glossy cod-liver-oil ads skip. Preformed vitamin A (retinol) is fat-soluble — your body stores it rather than flushing the excess — and it has a real upper limit. The tolerable upper intake level for adults is 3,000 micrograms RAE per day, per the NIH Office of Dietary Supplements. A single teaspoon of standard cod liver oil can carry roughly 400 to over 1,300 micrograms RAE of vitamin A, and some “high-vitamin” versions carry far more.

On its own, a teaspoon is usually fine. The problem is stacking. Add cod liver oil on top of a multivitamin that already contains retinol, plus the odd serving of actual liver, and you can quietly drift toward — or past — that ceiling without noticing, because nothing about it feels like an overdose. Chronic excess retinol is genuinely worth avoiding, which is why cod liver oil is one of the few supplements where “more” can work against you.

Vitamin D has a ceiling too — 100 micrograms (4,000 IU) per day for adults, per the NIH ODS — but a teaspoon of cod liver oil (typically 400–800 IU) leaves plenty of room. It’s the vitamin A you watch. Krill oil sidesteps this whole question: no retinol, no fat-soluble vitamin stack to blow through.

Omega-3: more per teaspoon in krill, but you take them differently

Gram for gram of oil, krill tends to carry more omega-3 than cod liver oil. But nobody takes them the same way: cod liver oil is a teaspoon or tablespoon; krill oil is a small capsule. So the real comparison isn’t spoon-to-spoon — it’s how much EPA and DHA lands on your label, and what form it’s in.

Krill’s omega-3 comes mostly bound to phospholipids; cod liver oil’s comes as triglycerides. Krill sellers (us included) like to point at the phospholipid form and claim better absorption. The honest version: the molecule that reaches your blood — EPA and DHA — is the same either way, and the “krill absorbs better” claim rests on a handful of small studies, not a mountain of them. We wrote a whole piece on that: same molecule, different vehicle. Don’t pay a big premium on the absorption argument alone.

How ours is made — and why we’ll tell you

Captains Krill Oil is pressed mechanically, on the boat, without solvents — closer to squeezing an orange than running a chemistry set. It’s a natural catch, so the omega-3 numbers vary a little lot to lot; we don’t blend or standardize the oil in a factory to hit a chosen figure on a box. We test lots at random and they come back strong, and documentation is available on request. Twenty years of doing it the same way is the whole reason we can answer questions like this one plainly.

Any brand — cod liver oil or krill — should be able to tell you how their oil was made and roughly what’s in it. If they can’t, keep your money.

You might not need either

If you eat oily fish — salmon, sardines, mackerel — about twice a week, you’re likely getting enough EPA and DHA from your plate, and you don’t need a krill capsule or a cod liver spoon for omega-3. See dietary sources of omega-3 before you buy anything.

If your actual gap is vitamin D in a dark winter, cod liver oil is the older, cheaper answer — or just a plain D3 supplement, which lets you dose vitamin D without dragging vitamin A along for the ride. Our krill oil can’t do that job, and we’re not going to pretend it can.

Where krill earns its place: you’re already covered on vitamins A and D, but there’s not much fish on your plate, and you want omega-3 without the fishy repeat or the retinol load. That’s the narrow lane Captains is built for. Dose to your goal and your blood work, not to a number on a box.

Frequently asked questions

Can I take krill oil and cod liver oil together?

You can, but there’s rarely a reason to, and you should watch your total vitamin A if you do. Cod liver oil brings retinol; krill oil brings extra omega-3 you may not need on top of it. If you already take cod liver oil for vitamin D, adding krill is just more omega-3 — useful only if your diet is genuinely short on it.

Does cod liver oil have more omega-3 than krill oil?

Per equal amount of oil, krill usually carries more omega-3 than cod liver oil. But they’re dosed differently — spoonfuls of cod liver oil versus small krill capsules — so compare the EPA and DHA totals on each label rather than assuming one wins. Cod liver oil’s real draw is its vitamins A and D, not its omega-3 count.

Is cod liver oil safe in pregnancy?

This is the big exception. Cod liver oil is high in preformed vitamin A, and too much retinol in pregnancy is linked to birth defects, so most guidance is to avoid cod liver oil while pregnant and get omega-3 from low-retinol sources instead. Talk to your doctor, and if you want omega-3 without the vitamin A load, that’s exactly the difference krill oil offers. This isn’t medical advice — your provider knows your situation.

Which is better for your heart?

For the omega-3 job that heart guidance actually tracks — lowering triglycerides — what matters is your total EPA and DHA, not whether it came from krill or cod. Both can contribute. Neither is a heart drug, and no supplement replaces diet, exercise, or the medication your doctor prescribes.

Why is krill oil more expensive?

Krill oil typically costs several times more per omega-3 dose than fish or cod liver oil, partly because of harvesting and processing, partly because of the astaxanthin and phospholipid marketing. If price is your deciding factor and you just want omega-3, cheaper options exist. If you want a clean, narrow omega-3 with no vitamin A load and you value how it’s made, that’s the case for paying more — but we’d rather you decide that than have us decide it for you.

Honest answer, not a pitch. — captainskrilloil.com

No. Chia and flax are loaded with omega-3, but it’s a different omega-3 than the one in fish — the plant form (ALA), not the EPA and DHA your heart and brain actually run on. Your body has to convert ALA into EPA and DHA before it can use it that way, and it does that job badly: single-digit percentages, and almost none of it reaches DHA. So a tablespoon of chia is real food with real omega-3 on the label, but most of that number never becomes the omega-3 the research is talking about.

That’s the whole answer. The rest is the honest detail — including the part where, for a lot of people, you don’t need a seed or a supplement.

Two different molecules wearing the same name

“Omega-3” isn’t one thing. It’s a family. The one in seeds is alpha-linolenic acid (ALA) — a short-chain, 18-carbon fat. The ones in oily fish are EPA and DHA — longer chains (20 and 22 carbons) that your cell membranes, your triglycerides, and your brain are built to use directly.

Chia and flax carry a lot of ALA. Fish carries preformed EPA and DHA. When a chia label brags “more omega-3 than salmon,” it’s counting ALA grams and quietly hoping you won’t ask whether your body can turn them into the fish kind. Mostly, it can’t.

The conversion tax nobody prints on the bag

Here’s the number that decides the whole question. According to the U.S. National Institutes of Health Office of Dietary Supplements, adults convert only about 5 to 8% of ALA into EPA, and less than 4% into DHA — often far less, closer to a fraction of a percent for DHA (NIH ODS Omega-3 Fact Sheet). Women of reproductive age convert at the higher end — up to roughly 21% to EPA — likely an estrogen effect. For most everyone else, the tax is brutal.

Put it in food terms. A tablespoon of chia or ground flax can hold around 2.4 grams of ALA. Run that through the conversion rates above and you’re left with maybe 0.05 to 0.24 grams of usable EPA and DHA — the range depends on who you are and what else you eat. A three-ounce piece of salmon delivers close to a full gram of EPA and DHA already assembled, no conversion tax owed. That’s why the two “omega-3” numbers aren’t comparable, even when the seed’s number looks bigger on paper.

It gets worse if your diet is high in omega-6 — the linoleic acid in most vegetable and seed oils. Omega-6 and ALA compete for the same enzymes, so a typical Western plate quietly throttles the conversion even further.

What happens when you test it in people

This isn’t just biochemistry on a whiteboard. In a randomized, double-blind, placebo-controlled trial in adults with high cholesterol, EPA and DHA improved blood lipids and inflammation markers — and ALA did not (Zhou et al., 2019, Molecular Nutrition & Food Research). More broadly, researchers now accept that in people eating an ordinary Western diet, you generally cannot raise your blood DHA by taking ALA. The conversion is simply too weak to move the number that matters.

To be fair — and we’d rather be fair than sell you something — it’s not zero. A carefully controlled year-long feeding study in 2025 found that flaxseed-oil ALA can nudge long-chain omega-3 levels up more than expected when the whole diet is managed for it (News-Medical, Dec 2025). So the door isn’t nailed shut. It’s just that “eat a tablespoon of chia and skip the fish” is not how you walk through it.

You might not need any of this — seeds or us

Here’s the part a supplement seller isn’t supposed to say. If you eat oily fish — salmon, sardines, mackerel, herring — twice a week, you’re already getting preformed EPA and DHA and there’s very little gap to fill. Not with chia. Not with flax. Not with a capsule, ours included. Keep eating the fish and you can stop reading here.

And if you’re vegan or vegetarian and you genuinely want EPA and DHA, the honest answer still isn’t seeds — it’s algae oil, which is where the fish get their omega-3 in the first place. That’s the plant-based source that actually delivers the long-chain fats without the conversion tax. It isn’t us, and we’ll say so.

None of that makes chia or flax bad. They’re excellent food — fiber, protein, minerals, and yes, some omega-3. Eat them for what they are. Just don’t ask a tablespoon of seeds to do a salmon’s job. (For the food-first version of this answer, see our short note on dietary sources of omega-3.)

Where Captains fits — and where it doesn’t

Captains Krill Oil™ is the fish-type omega-3: preformed EPA and DHA, carried in the phospholipid form that krill store it in. It’s a raw natural catch, extracted mechanically on the boat rather than pulled out with chemical solvents in a factory — which also means the oil is a real animal product that varies a little lot to lot, the way real food does. We test lots at random and they come back strong. Twenty years of doing it the same way.

But Captains only earns its place if you actually have a gap — you don’t eat the fish, and you want the EPA and DHA without the seed-conversion lottery. If you already eat oily fish twice a week, you don’t need us. That’s not modesty; it’s just the truth about where this particular oil helps and where it doesn’t.

Honest answer, not a pitch. — captainskrilloil.com

Frequently asked questions

Is chia or flax better than fish oil for omega-3?

For the plant form (ALA), seeds are excellent. For the EPA and DHA your heart and brain use directly, fish (or fish/krill oil) wins clearly, because your body converts only a small fraction of ALA into those long-chain fats. Different job, different molecule.

How much ALA do I need to equal the EPA and DHA in fish?

There’s no clean ratio, because conversion varies by person, sex, and diet. As a rough sense of scale: a tablespoon of chia (~2.4 g ALA) might yield only 0.05–0.24 g of usable EPA and DHA, while a 3-ounce serving of salmon delivers close to a full gram already formed. That’s why “gram for gram” comparisons on seed labels are misleading.

Can vegans get enough EPA and DHA from seeds?

Not reliably. In people on typical diets, ALA supplementation doesn’t dependably raise blood DHA. Vegans and vegetarians who want EPA and DHA are usually better served by an algae-based oil, which supplies the long-chain fats directly without needing conversion.

Do women convert ALA better than men?

Somewhat. Women of reproductive age can convert up to roughly 21% of ALA to EPA — likely an estrogen effect — versus single digits for most adults. Even at the high end, conversion to DHA s
