The full scoring method: How we score
MCT oil benefits: where the science stands
Almost nobody has looked.
As of August 2026, 379 papers on PubMed mention MCT oil, but almost none put it to a real test. For weight and body fat, the best evidence is just a trial, and they lean positive. Early signs, not proof. Every claim we checked is below.

Fair questions
Does MCT oil work?+
Nobody can honestly say: almost no real studies exist, whatever the label promises.
Is MCT oil safe?+
No caution is recorded on this page. That is not a safety guarantee; the studies we read were not safety trials.
Why only 10 sources, when PubMed lists 379?+
The 379 is every paper that mentions MCT oil in any way: animal studies, blood measurements, papers where it is a side note. The strongest sources are combined reviews, and each one already gathers every trial its authors could find. Our 10 cover 27 trials between them, and every one is linked above. Both counts are measured, not estimated.
