Pure MCT oil does not raise cholesterol according to a 2021 meta-analysis published in the Journal of Nutrition, which found no significant effect on total cholesterol, LDL cholesterol, or HDL cholesterol levels across seven studies. However, regular coconut oil does raise LDL cholesterol because it contains about 42% lauric acid, a medium-chain fatty acid that behaves more like long-chain saturated fats and increases "bad" LDL cholesterol while also raising "good" HDL cholesterol. The critical distinction is that MCT oil and coconut oil are not the same: commercial MCT oil is typically 100% caprylic (C8) and capric (C10) acid with lauric acid removed, whereas coconut oil's lauric acid content drives its cholesterol-raising effects.
The Science Behind MCT Oil and Cholesterol
A comprehensive meta-analysis of seven studies published on September 30, 2021, examined the effects of MCT oil on blood lipids in over 300 participants and reached definitive conclusions about cholesterol impact. The researchers found that MCT oil intake did not affect total cholesterol (0.04 mmol/L; 95% CI, -0.11 to 0.20), LDL cholesterol (0.02 mmol/L; 95% CI, -0.13 to 0.17), or HDL cholesterol (-0.01 mmol/L; 95% CI, -0.10 to 0.09).
However, the same analysis did find a small increase in triglycerides (0.14 mmol/L; 95% CI, 0.01-0.27) when participants consumed MCT oil. This triglyceride increase is important for people monitoring their complete lipid profile, even though cholesterol levels remained stable.
Key Statistical Findings from the 2021 Meta-Analysis
| Lipid Measure | Mean Change (mmol/L) | 95% Confidence Interval | Statistically Significant? |
|---|---|---|---|
| Total Cholesterol | 0.04 | -0.11 to 0.20 | No |
| LDL Cholesterol | 0.02 | -0.13 to 0.17 | No |
| HDL Cholesterol | -0.01 | -0.10 to 0.09 | No |
| Triglycerides | 0.14 | 0.01 to 0.27 | Yes |
Subgroup analyses revealed important nuances in the data: the effects of MCT oil on total cholesterol and LDL cholesterol differed based on the fatty acid profile of the control oil used for comparison. When MCT oil was compared to unsaturated fatty acids, it showed slight increases in total and LDL cholesterol, but when compared to longer-chain saturated fatty acids, there was evidence for reductions.
Why Coconut Oil Raises Cholesterol But MCT Oil Doesn't
The British Heart Foundation explicitly states that coconut oil raises LDL cholesterol due to its saturated fat content, including lauric acid. Despite popular health claims, current research does not support the idea that coconut oil is heart-healthy.
- Lauric acid comprises approximately 42% of coconut oil's fatty acid profile
- Lauric acid raises both LDL-C and HDL-C levels significantly
- The LDL increase from coconut oil is not canceled out by HDL increases
- Pure MCT oil typically contains zero lauric acid, using only C8 and C10 fatty acids
- MCTs are absorbed quickly and used for energy rather than stored as fat
Coconut oil contains mostly lauric acid, which is sometimes labeled as an MCT but has effects on cholesterol more similar to longer-chain fats found in butter and fatty meat. Studies comparing coconut oil with other vegetable oils consistently show that the saturated fat in coconut oil raises bad LDL cholesterol.
Detailed Comparison: MCT Oil vs. Coconut Oil
| Characteristic | Pure MCT Oil | Coconut Oil |
|---|---|---|
| Lauric Acid Content | 0% | 42% |
| Primary Fatty Acids | C8 (caprylic), C10 (capric) | Lauric acid (C12) |
| Effect on LDL Cholesterol | No significant change | Increases significantly |
| Effect on HDL Cholesterol | No significant change | Increases moderately |
| Effect on Triglycerides | Small increase (+0.14 mmol/L) | Variable |
| Processing | Refined/processed from coconut or palm | Minimal processing |
How to Use MCT Oil Safely for Heart Health
MCT oil in your diet can potentially help lower LDL cholesterol while increasing HDL cholesterol when used as part of a balanced ketogenic diet that promotes weight loss. Weight reduction itself reduces heart disease risk factors.
- Start with 1 teaspoon daily and gradually increase to 1-2 tablespoons maximum
- Replace saturated fats like butter or coconut oil with MCT oil, not add it on top
- Combine MCT oil with unsaturated fats like olive oil for best lipid profile outcomes
- Monitor triglyceride levels if using MCT oil long-term due to the small triglyceride increase
- Choose products labeled "lauric acid-free" to ensure pure C8/C10 MCT content
It's generally safe to use MCT oil moderately, but you should be careful when using it long-term without medical supervision. Large amounts of saturated fat from any source may raise cholesterol, so moderation remains essential.
Expert Recommendations for Cholesterol Management
When it comes to keeping cholesterol levels healthy, the advice remains the same: replacing saturated fats like those found in coconut oil with unsaturated fats like rapeseed, olive, and sunflower oil is still the most effective way to reduce bad LDL cholesterol levels. Coconut oil can still be used occasionally, but like all oils, in moderation.
For those wishing to incorporate coconut oil into their diets, healthcare professionals recommend limiting use to under 10% of total daily caloric consumption in line with current saturated fatty acid intake guidelines. This translates to approximately 2 tablespoons for a 2,000-calorie diet based on 2021 American Heart Association guidelines.

Important Considerations for Specific Populations
People with existing heart disease or high cholesterol should consult their healthcare provider before regularly consuming either coconut oil or MCT oil, even though pure MCT oil shows neutral cholesterol effects. The subgroup analysis showing MCT oil increases cholesterol when compared to unsaturated fats suggests that what you replace matters critically.
Pacific Islander studies found that lean, heart disease-free populations consuming up to 63% of calories from coconut fat saw total cholesterol rise along with HDL, but this doesn't translate to increased heart attack risk in that specific population. However, these findings shouldn't be generalized to all populations without further long-term clinical trials.
FAQ Section
Remember that label reading is essential since some products labeled "MCT oil" may contain lauric acid from coconut sources, blunting the cholesterol-neutral benefits. Always choose products specifying 100% C8/C10 with "lauric acid-free" labeling for guaranteed cholesterol-neutral effects.
What are the most common questions about Will Mct Coconut Oil Raise Cholesterol Or Lower It?
What Happens if You Use Too Much MCT Oil?
Large doses could lead to fat buildup in the liver over time if consumed excessively. MCTs may also stimulate the release of hunger hormones, potentially making you overeat and gain weight. The high calorie content (120 calories per tablespoon) can cause weight gain if not accounted for in your daily caloric intake.
Does MCT coconut oil raise cholesterol?
Pure MCT oil does not raise cholesterol levels, but coconut oil does raise LDL cholesterol due to its 42% lauric acid content. They are different products with different effects on blood lipids.
Is MCT oil better than coconut oil for cholesterol?
Yes, pure MCT oil is better for cholesterol management because it contains no lauric acid and shows no significant effect on LDL cholesterol, while coconut oil consistently raises LDL cholesterol.
How much MCT oil can I safely consume daily?
You can safely consume 1-2 tablespoons (15-30 ml) of MCT oil daily when replacing other saturated fats, but start with 1 teaspoon to assess tolerance.
Can MCT oil cause weight gain?
Yes, MCT oil can cause weight gain if consumed in large amounts because it contains 120 calories per tablespoon and may stimulate hunger hormones that lead to overeating.
What's the difference between C8, C10, and lauric acid MCTs?
C8 (caprylic acid) and C10 (capric acid) are true MCTs that don't raise cholesterol, while lauric acid (C12) behaves like long-chain saturated fats and does raise LDL cholesterol.
