Understanding the Terminology Behind MCT Oil
To answer the question, "What is another name for MCT oil?" it's essential to understand that the supplement is a concentrated source of medium-chain triglycerides, or MCTs. The most precise and commonly used alternative name is therefore medium-chain triglycerides. However, depending on its specific composition and context, it can also be referred to by a few other names.
The Most Common Alternative Names
- Caprylic/Capric Triglyceride: This is one of the most accurate alternative names and is often found on ingredient lists for supplements, cosmetics, and food products. It refers to a common blend of two specific medium-chain fatty acids: caprylic acid (C8) and capric acid (C10). These two fatty acids are prized for their rapid absorption and metabolism into ketones, making them staples in many MCT formulations.
- Fractionated Coconut Oil: Many MCT oils are derived from coconut oil, which is fractionated, or separated, to isolate the medium-chain fats. This process removes the longer-chain fatty acids and concentrates the MCTs. While many commercial MCT oils are essentially fractionated coconut oil, the two are not always identical. Some products labeled simply as 'fractionated coconut oil' may still contain more of the slower-metabolizing lauric acid (C12) than a premium MCT oil, which typically features a higher concentration of C8 and C10.
Less Common and Technical Names
- Medium-Chain Triacylglycerols: This is a more technical, biochemical name for MCTs. While less common in consumer-facing marketing, it is used in scientific literature and discussions.
- Individual Fatty Acid Names: The different types of medium-chain fatty acids can also be mentioned individually, depending on the product's focus. A product might be marketed as a "C8 oil" or contain specific mention of caprylic acid, capric acid, or even lauric acid (C12). The specific fatty acid composition is a key differentiator between MCT products.
The Role of Different MCT Fatty Acids
Not all MCTs are created equal. The type of fatty acid and its carbon chain length (C6, C8, C10, C12) determines how quickly it is metabolized into energy. This has led to the development of specialized MCT oil products focusing on certain fatty acid profiles.
Types of Medium-Chain Fatty Acids
- Caproic Acid (C6): Contains 6 carbon atoms. While it is an MCT, it is rarely used in supplements due to its unpleasant taste and odor.
- Caprylic Acid (C8): Contains 8 carbon atoms. This is the preferred MCT for rapid ketone production and is often found in high-quality, pure C8 MCT oil products.
- Capric Acid (C10): Contains 10 carbon atoms. Also converts to ketones efficiently, though slightly slower than C8. It is commonly blended with C8 for a balanced effect.
- Lauric Acid (C12): Contains 12 carbon atoms. Although technically an MCT, it behaves more like a long-chain fatty acid and is metabolized more slowly. It is a major component of coconut oil but is often removed from premium MCT oil products.
The Difference Between MCT Oil and Its Sources
It's a common misconception that MCT oil is simply coconut oil. While coconut and palm kernel oil are the primary sources, a standard coconut oil is not the same as a concentrated MCT oil supplement. A key difference lies in their fatty acid profiles.
Comparison Table: MCT Oil vs. Coconut Oil
| Feature | MCT Oil (Supplement) | Coconut Oil (Natural Source) |
|---|---|---|
| Composition | Concentrated source of medium-chain triglycerides (MCTs), primarily C8 and C10. | A mix of various fatty acids, including MCTs (around 55%) and longer-chain fats. |
| MCT Concentration | Very high, typically containing a high percentage of C8 and C10. | Lower, with a larger percentage of lauric acid (C12). |
| Ketone Production | Supports very rapid ketone production due to high levels of C8 and C10. | Slower ketone production because the C12 component is processed differently by the body. |
| Digestion | Absorbed very quickly and sent directly to the liver for energy. | Digested and absorbed more slowly than MCT oil. |
| Uses | Primarily used as a dietary supplement for keto diets, energy, and cognitive function. | Used for cooking, baking, skincare, and other applications, in addition to health benefits. |
Conclusion: The Right Name for Your Needs
Ultimately, understanding the different names for MCT oil is a matter of knowing the context. For most people, medium-chain triglycerides or the abbreviated MCTs are the most recognizable and accurate names. However, a brand or product might use the technical name Caprylic/Capric Triglyceride to specify its fatty acid composition, or the more generic fractionated coconut oil to indicate its source. Knowing these distinctions can help consumers make a more informed choice when selecting a supplement tailored to their specific health and dietary goals.

Key Takeaways
- Primary Alternative Name: The most direct and common alternative name for MCT oil is medium-chain triglycerides, often abbreviated as MCTs.
- Technical Ingredient Name: On supplement and cosmetic labels, you will frequently see the technical name Caprylic/Capric Triglyceride, referring to the blend of C8 and C10 fatty acids.
- Source-Based Alias: When derived from coconuts, it can also be called fractionated coconut oil, though this term can be less precise in defining the C8/C10 concentration.
- Individual Fatty Acids: The different components of MCT oil have their own names, such as caprylic acid (C8) and capric acid (C10), with the former being the fastest-metabolizing.
- Not the Same as Coconut Oil: Despite being derived from it, pure MCT oil is not the same as standard coconut oil; the former is more concentrated and has a different fatty acid profile.
