Is Coconut Oil the Same as MCT Oil? Understanding the Differences and Benefits
Coconut oil and MCT oil are both derived from coconuts, but they are not the same. MCT oil is a concentrated source of specific medium-chain triglycerides (MCTs) found in coconut oil, offering potentially more potent benefits, while coconut oil contains a wider range of fatty acids, including some MCTs.
Understanding the Background: Fatty Acids and Triglycerides
To understand the difference, let’s delve into the chemistry of fats. Fats, also known as triglycerides, are composed of a glycerol molecule and three fatty acids. These fatty acids can be categorized by their chain length:
- Short-chain fatty acids (SCFAs): Less than 6 carbon atoms.
- Medium-chain fatty acids (MCTs): 6-12 carbon atoms.
- Long-chain fatty acids (LCFAs): 13-21 carbon atoms.
- Very long-chain fatty acids (VLCFAs): 22 or more carbon atoms.
The length of the fatty acid chain significantly impacts how the body digests and metabolizes it. MCTs are more easily digested and absorbed than LCFAs, making them a readily available source of energy.
Coconut Oil Composition: A Spectrum of Fatty Acids
Coconut oil is primarily composed of saturated fats, with the following approximate breakdown of fatty acids:
- Lauric Acid (C12): ~49%
- Myristic Acid (C14): ~18%
- Caprylic Acid (C8): ~8%
- Capric Acid (C10): ~7%
- Palmitic Acid (C16): ~8%
- Other Fatty Acids (C6, C18, etc.): ~10%
Notice that only a portion of coconut oil is actually composed of MCTs (caprylic and capric acid). The remaining fatty acids, like lauric and myristic acid, behave more like LCFAs in the body.
MCT Oil Production: Concentrating the Good Stuff
MCT oil is manufactured through a process called fractionation. This process separates the different fatty acids present in coconut oil (or palm kernel oil) to isolate and concentrate the MCTs, specifically caprylic acid (C8) and capric acid (C10). Some MCT oils also contain caproic acid (C6) and lauric acid (C12), although the best MCT oils typically prioritize C8 and C10 for optimal ketone production.
This fractionation can be accomplished in a few ways:
- Steam Distillation: Uses heat and steam to separate fatty acids based on boiling points.
- Enzymatic Hydrolysis: Uses enzymes to break down triglycerides and then separates the fatty acids.
The resulting MCT oil is a highly concentrated source of MCTs, often containing close to 100% MCTs.
Benefits of MCT Oil: Enhanced Energy and More
MCT oil is touted for several potential health benefits, primarily due to its unique metabolic properties:
- Rapid Energy Source: MCTs are quickly absorbed and transported directly to the liver, where they are used for energy or converted into ketones.
- Ketone Production: MCTs, particularly caprylic acid (C8), are efficiently converted into ketones, making them a popular supplement for those following a ketogenic diet.
- Weight Management: Some studies suggest that MCT oil may help with weight management by promoting satiety and increasing energy expenditure.
- Improved Cognitive Function: Ketones produced from MCTs can cross the blood-brain barrier and provide an alternative fuel source for the brain, potentially improving cognitive function.
- Gut Health: MCTs have demonstrated antimicrobial properties, which could help to balance gut bacteria.
Potential Benefits of Coconut Oil: A Broader Spectrum
Coconut oil also offers some health benefits, but they are often attributed to its overall fatty acid profile, not just its MCT content:
- Improved Cholesterol Levels: While high in saturated fat, some studies suggest that coconut oil may increase HDL (“good”) cholesterol levels.
- Skin and Hair Health: Coconut oil is commonly used as a moisturizer for skin and hair.
- Antimicrobial Properties: Lauric acid, a major component of coconut oil, has antimicrobial properties.
- Satiety: The fat content of coconut oil can promote feelings of fullness.
Common Mistakes and Considerations
When choosing between coconut oil and MCT oil, consider the following:
- Confusing Labeling: Pay close attention to labels. Some products marketed as “MCT oil” may contain significant amounts of lauric acid. Look for oils with high concentrations of C8 and C10.
- Dosage: Start with a low dose of MCT oil (1 teaspoon per day) to assess tolerance, as it can cause digestive upset in some individuals. Gradually increase the dosage as tolerated. Coconut oil can be used more liberally, but moderation is key.
- Cooking: Coconut oil is suitable for cooking at high temperatures due to its stability. MCT oil, particularly the C8 and C10 varieties, is not ideal for high-heat cooking as it has a lower smoke point and can degrade.
- Individual Needs: Consider your specific goals. If you are following a ketogenic diet and want to maximize ketone production, MCT oil (specifically C8) is likely a better choice. If you are looking for a general-purpose cooking oil and moisturizer, coconut oil may be sufficient.

Frequently Asked Questions (FAQs)
What are the different types of MCTs, and which is best?
MCTs are categorized by their carbon chain length: C6 (Caproic Acid), C8 (Caprylic Acid), C10 (Capric Acid), and C12 (Lauric Acid). C8 (Caprylic Acid) is generally considered the most efficient for ketone production due to its rapid conversion in the liver. C10 is also a good option, while C6 can cause more digestive upset, and C12 (Lauric Acid) is metabolized more like a long-chain fatty acid.
Can I use coconut oil on a ketogenic diet?
Yes, you can use coconut oil on a ketogenic diet, but MCT oil will be more effective at boosting ketone levels. Coconut oil contains some MCTs, but not as much as MCT oil. Supplementing with pure MCT oil (C8 and C10) can help you reach and maintain ketosis more easily.
Does MCT oil have a taste?
Pure MCT oil is generally tasteless and odorless. This makes it easy to add to foods and beverages without altering their flavor. Some MCT oils may have a slightly oily or soapy taste, which can be minimized by choosing a high-quality brand.
What are the side effects of MCT oil?
The most common side effects of MCT oil are digestive upset, including diarrhea, nausea, and stomach cramps. These side effects can be minimized by starting with a small dose (1 teaspoon per day) and gradually increasing the dosage as tolerated. It’s also best to take MCT oil with food.
Is MCT oil safe for everyone?
While generally safe, MCT oil may not be suitable for everyone. Individuals with liver problems or fat malabsorption issues should consult with a healthcare professional before using MCT oil. It’s also important to note that MCT oil is high in calories, so it should be consumed in moderation.
Can MCT oil help with Alzheimer’s disease?
Some research suggests that ketones produced from MCTs may provide an alternative fuel source for the brain, potentially improving cognitive function in individuals with Alzheimer’s disease. However, more research is needed to confirm these benefits.
How should I store MCT oil and coconut oil?
Both MCT oil and coconut oil should be stored in a cool, dark place. Coconut oil has a high smoke point and long shelf life, whereas MCT oil should be stored at lower temperatures. Refrigeration can extend the shelf life of both oils, but it is not required for MCT oil.
Can I cook with MCT oil?
It’s generally not recommended to cook with MCT oil at high temperatures because it has a low smoke point and can degrade, losing its beneficial properties. Coconut oil is a better option for high-heat cooking. You can add MCT oil to already cooked foods or use it in salad dressings or smoothies.
Are there different grades of MCT oil?
Yes, there are differences in the quality and purity of MCT oil. Look for third-party tested MCT oils to ensure they are free from contaminants and contain the specified MCT composition. Choose reputable brands that use high-quality sourcing and manufacturing processes.
Is MCT oil the same as CLA (Conjugated Linoleic Acid)?
No, MCT oil and CLA are different types of fatty acids with distinct properties and benefits. MCT oil is composed of medium-chain triglycerides, while CLA is a type of omega-6 fatty acid. They are not interchangeable.
Can I use MCT oil for oil pulling?
While coconut oil is traditionally used for oil pulling, some people use MCT oil. The purported benefits are similar: reducing bacteria and promoting oral hygiene. However, coconut oil’s lauric acid gives it stronger antimicrobial properties that are more desirable for oral health.
Does MCT Oil help with athletic performance?
MCT oil can provide a quick energy source that may benefit athletes during endurance events. Some studies suggest it can improve performance, but more research is needed. It is important to note that high initial doses can cause stomach upset that impairs performance. Start with a low dose and experiment during training to assess tolerance.
