Best MCT Oil Supplements 2026: Cost per Effective Dose
Top pick for MCT Oil: Sports Research Organic MCT Oil — 14g per 1 tbsp (15mL), None stated, $0.38/day.
All MCT Oil Supplements Compared
The split that matters is C8 versus a C8/C10 blend. Caprylic acid (C8) converts to ketones fastest and is what most ketogenic protocols are actually referring to, while cheaper blends dilute it with C10 and sometimes lauric acid. Serving sizes here are unusually consistent at around 14–15 g, so cost per day is a fair comparison in this category — check the C8 percentage on the label, since it is the variable the price tracks.
All 6 products sorted by cost per clinically-effective daily dose (lowest first). Dose, certification, and pricing verified against NIH DSLD and manufacturer data.

How We Rank MCT Oil Supplements
Every product is evaluated on three criteria:
- Cost per day. Not cost per pill or cost per bottle — what it actually costs per day at the product's labelled serving. Where a category's servings differ in strength we flag it above the table, because cost per day is only comparable when the doses are.
- Third-party certification. USP Verified, NSF Certified for Sport, and ConsumerLab Approved indicate independent testing for purity, potency, and contaminants.
- Bioavailable form. We prioritize products using the specific chemical form shown to be most effective in published research.
Rankings are not influenced by affiliate commissions. We earn the same commission regardless of which product you choose. Read our full methodology.
