How we rank
We rank by cost-per-dose — price ÷ servings, normalized to the daily dose — so bottle sizes and strengths compare fairly. Prices are scraped at publication and re-checked when the catalog refreshes (see the “Prices checked” stamp above). There is no paid placement and no kickback for ordering. Full methodology · Editorial standards.
When cheapest ≠ best value
The cheapest bottle isn’t automatically the best value: a low-absorption form (magnesium oxide is the classic example) can look cheap per milligram yet deliver less of what you actually absorb. Where forms differ, compare cost per absorbed or elemental unit, not the compound weight on the label. A bigger bottle isn’t automatically cheaper per dose either — this list already ranks by cost per dose, so a larger count only wins if it truly costs less per serving. Compare Cod Liver Oil forms.
Our data on this: how much the big bottle saves per serving · the gummy tax · the form premium · the price spread.
Full ranking by cost per dose
Cost-per-serving normalizes price across bottle sizes — a 60-count and a 365-count compare fairly.

Cod Liver Oil brands we compare — which are third-party tested?
1 of the 6 brands ranked above appear in an independent certifier's own public registry. A certification confirms the label matches the contents — it says nothing about how well the supplement works, and an uncertified brand is not automatically worse.

How much does Cod Liver Oil cost per day?+
The cheapest cod liver oil we track works out to $0.05 per serving, against a typical $0.12 per serving across the 11 we can price per dose. Retailers and review sites list a price and a serving size but rarely divide it out — this is what a day actually costs, as of September 2026.
What is the typical cost per dose for Cod Liver Oil?+
About $0.12 per serving across the 11 cod liver oil products we can price per dose (combination products are left out — their single label dose belongs to whichever ingredient the product is built around) — the cheapest we track is $0.05 per serving, with most falling between $0.08 and $0.24.
What is the highest-quality Cod Liver Oil supplement?+
Of the 6 cod liver oil brands ranked here, 1 hold a third-party certification we could verify in a public registry: Nordic Naturals (NSF Certified for Sport). Certification means an independent lab confirmed the label matches the contents and screened for contaminants — it does not rate how well the supplement works. The cheapest certified option is Nordic Naturals Arctic Cod Liver Oil at $0.71 per serving.
Which Cod Liver Oil brands are third-party tested?+
Nordic Naturals — NSF Certified for Sport. We only count a brand as tested when it appears in the certifier's own public registry (USP Verified, NSF Certified for Sport, Informed Choice), never on a claim printed on the label. The remaining 5 brands on this page have no certification we could verify.
Which Cod Liver Oil is the top rated?+
We don't republish marketplace star ratings — they belong to the retailer, they move constantly, and a 4.6 average tells you nothing about what is in the capsule. The two things you can verify are what a dose costs and whether an independent lab checked the label. On both counts, Nordic Naturals Arctic Cod Liver Oil stands out: NSF Certified for Sport certified at $0.71 per serving.
What dose of Cod Liver Oil do these supplements come in?+
The cod liver oil products we track range from 460mg to 1245mg per serving. We rank by cost per serving so you can compare value across strengths — check the label for the dose that suits you.
Independent testing
1 of 6 tracked Cod Liver Oil brands here are flagged as carrying independent third-party testing — a voluntary check of a product's identity, potency and contaminants by an outside lab. It's a quality signal, not a value or efficacy claim. Confirm any brand's current status on the official registries:
Testing status is self-reported by the brand or drawn from public certification and may change — always verify on the official registry before purchase.
