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.
