What 6 MCT Oil labels show
Priced per day, these MCT oil products run $0.42 to $1.26 — a 3.0× gap between the cheapest and dearest MCT oil here, across 4 brands.
Servings here are close enough to compare directly, so the gap is a real one: Sports Research at $0.42 buys the same thing as Sports Research at $1.26.
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.

What the published reviews of MCT Oil concluded
- Medium Chain Triglycerides induce mild ketosis and may improve cognition in Alzheimer's disease. A systematic review and meta-analysis of human studies. · Ageing research reviews, 2020
“In this meta-analysis, we demonstrated that MCTs can induce mild ketosis and may improve cognition in patients with mild cognitive impairment and Alzheimer's disease. However, risk of bias of existing studies necessitates future trials.”
- The impact of medium-chain triglycerides on weight loss and metabolic health in individuals with overweight or obesity: A systematic review and meta-analysis. · Clinical nutrition (Edinburgh, Scotland), 2024
“Hence, the authors recommend incorporating pure MCTs in dietary interventions for individuals with overweight and obesity, particularly those with comorbidities such as dyslipidemia and impaired glucose metabolism.”
- Effects of medium-chain triglycerides on weight loss and body composition: a meta-analysis of randomized controlled trials. · Journal of the Academy of Nutrition and Dietetics, 2015
“Replacement of LCTs with MCTs in the diet could potentially induce modest reductions in body weight and composition without adversely affecting lipid profiles.”
- Medium-chain triglycerides may improve memory in non-demented older adults: a systematic review of randomized controlled trials. · BMC geriatrics, 2022
“MCT supplementation may enhance working memory in non-demented older adults. These effects may be more prominent in individuals with lower baseline scores, from short and long-term supplementation.”
Method: PubMed searched in humans for systematic reviews and meta-analyses with MCT Oil in the title; these 4 of the 12 that qualified are shown with the authors’ own conclusion quoted rather than summarised. What it cannot tell you: whether MCT Oil will work for you — each of these reports an average across trials published 2015–2024, and null findings are shown here as readily as positive ones.
How these 6 MCT Oil products were ranked
Not one of these 6 MCT oil products could be confirmed in the NSF, USP or Informed Sport registries, so verification separates none of them and the ranking falls to cost per day at the labelled serving. Commission does not enter it: the rate is the same whichever MCT oil you buy. Full methodology.
