Medium-chain triglycerides

Medium-chain triglycerides are a class of saturated fat composed of fatty acids containing 6-10 carbons. They are found primarily in coconut oil, palm kernel oil, and dairy fat, and they appear to benefit fat loss to a minor extent when consumed in place of other dietary fat.

Our evidence-based analysis on medium-chain triglycerides features 105 unique references to scientific papers.

Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The more evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
Notes
grade-c Minor Moderate See all 4 studies
Appears to be a short lived and of small magnitude increase in metabolic rate.
grade-d Minor - See study
May decrease fat mass to a greater degree than an isocaloric amount of long chain fatty acids.
grade-d Minor - See study
Appears to increase the percentage of calories derived from lipids in obese persons; no comparator.
grade-d Minor - See study
Administration of purified MCTs results in a decrease in HDL-C in diabetics that is minor and likely not practically relevant.
grade-d Minor - See study
May improve insulin sensitivity in diabetics, requires more evidence though as the one study was confounded with fat loss.
grade-d Minor - See study
Has been implicated in increasing serum ketones more than other fatty acids.
grade-d Minor - See study
Administering purified MCTs to diabetics results in a non-significant reduction of LDL-C.
grade-d Minor - See study
A decrease in total cholesterol (both the LDL and HDL portions) has been noted with purified MCTs to a minor degree, relative to longer chain fatty acids.
grade-d Minor - See study
Appears somewhat effective in reducing weight of obese persons to a greater degree than an isocaloric amount of longer chain fatty acids
grade-d - - See study
grade-d - - See study
grade-d - - See study
Insufficient evidence to support alterations in blood glucose.
grade-d - - See study
No significant influence detected on fasting insulin levels following coconut oil consumption
grade-d - See study
Was able to attenuate the rate of skeletal muscle loss during a hypocaloric diet in obese persons; unknown if this applies to lean persons and may be related to ketone production.
grade-d - - See study
Insufficient evidence to support alterations in the thermic effect of food compared to other oils
grade-d - - See study
Insufficient evidence to support changes in serum triglycerides.
