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 per-bottle price usually just means fewer servings or a smaller dose per serving. That is exactly what cost per dose normalises, which is why the ranking above is ordered by it rather than by sticker price. A bigger bottle isn’t automatically cheaper per dose either — this list already ranks by cost per gram of active, so a larger count only wins if it truly costs less per serving. Compare MCT 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 gram of active normalizes price across scoop sizes — a 20 g and a 25 g serving compare fairly.

Is the cheapest MCT oil always the best value?+

What is the highest-quality MCT oil supplement?+
None of the 2 mct oil brands ranked here carry a USP, NSF or Informed-Sport certification we could confirm in the public registries as of October 2026. That does not make them bad — most supplement brands never submit to voluntary testing — but if independent verification matters to you, check the registries linked below before buying.
Which MCT oil brands are third-party tested?+
None of the 2 brands on this page appear in the USP, NSF or Informed-Sport public registries. We never count a "lab tested" claim printed on a label as third-party testing — only an entry in the certifier's own registry.
Which MCT 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 this page the best value is Garden of Life Dr. Formulated Keto Organic MCT Powder… at $0.13 per gram; no brand here holds a certification we could verify in a public registry.
Independent testing
Independent third-party testing is 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.
