Understanding the Composition of MCT Oils
Medium-chain triglycerides (MCTs) are a type of fatty acid typically containing a carbon chain of 6 to 12 atoms. These are metabolized differently from long-chain triglycerides, being absorbed more rapidly and transported directly to the liver for quick energy conversion into ketones. However, not all MCTs are created equal. The four primary types are caproic acid (C6), caprylic acid (C8), capric acid (C10), and lauric acid (C12).
The Deliberate Exclusion of Lauric Acid
Bulletproof, a brand known for its biohacking principles, formulates its MCT products to maximize rapid energy and cognitive benefits. Bulletproof MCT oil (formerly XCT Oil) contains a blend of C8 and C10, while their Brain Octane oil is made exclusively of C8. A key part of this formulation is the intentional removal of lauric acid (C12) during the extraction process. This is because while lauric acid is technically classified as an MCT due to its 12-carbon chain, its metabolic pathway is slower and more closely resembles that of long-chain fatty acids. Instead of being immediately converted into ketones like C8 and C10, C12 takes a longer digestive route, making it less efficient for the rapid fuel production favored by those on a ketogenic diet.
The Science Behind the Refinement
The process of creating MCT oil from its source, typically coconut oil, is known as fractionation. Coconut oil contains approximately 60% MCTs, but a large portion of this is lauric acid (around 50% of the fatty acids in coconut oil). To create a potent MCT oil supplement, manufacturers isolate the more desirable C8 and C10 fatty acids. Bulletproof takes this a step further, with its Brain Octane offering pure C8, the most ketogenic and rapidly absorbed MCT. This intense focus on purity is central to the Bulletproof philosophy of providing clean, efficient fuel for the body and mind.
Comparison: Bulletproof MCT Oil vs. Coconut Oil
To truly understand why Bulletproof MCT oil is different, it helps to compare it directly to its source ingredient, coconut oil. This contrast highlights the specific performance benefits of the refined product.
| Feature | Bulletproof MCT Oil (e.g., Brain Octane) | Coconut Oil |
|---|---|---|
| Lauric Acid (C12) Content | None | High (approx. 50%) |
| Caprylic Acid (C8) Content | High (e.g., 100% in Brain Octane) | Low (approx. 6%) |
| Ketone Production Speed | Very rapid, as C8 is the most ketogenic | Slower, due to the higher proportion of C12 |
| Source | 100% non-GMO coconuts | The entire coconut meat |
| Physical State at Room Temperature | Liquid | Solid below 75°F (23.9°C) |
| Flavor | Flavorless and odorless | Distinct coconut flavor |
| Primary Purpose | Fast energy, cognitive function, and ketosis support | Cooking, moisturizing, general health benefits |
Benefits and Considerations of Excluding Lauric Acid
By removing lauric acid, Bulletproof MCT oil offers several distinct advantages for those seeking maximum ketogenic benefit. The faster-metabolizing C8 and C10 fatty acids provide a rapid and sustained source of clean energy for the brain and body. This targeted approach is ideal for those who practice intermittent fasting or follow a strict ketogenic diet, where immediate ketone production is the goal. However, it's worth noting that lauric acid itself has health benefits, including antimicrobial properties, which are not present in the highly refined C8/C10 products. For general health or cooking, coconut oil may still be a beneficial option, but for peak ketogenic performance, the purity of Bulletproof's formula is why lauric acid is intentionally left out.
Potential for Side Effects
For those new to concentrated MCT oil, a potential side effect is digestive upset, sometimes referred to as 'disaster pants'. The rapid absorption of these fatty acids can overwhelm the digestive system. It is always recommended to start with a small dosage, such as one teaspoon, and gradually increase to the full serving size as your body adjusts. The absence of lauric acid does not prevent this issue, as it is a characteristic of concentrated MCTs in general.

Conclusion
In summary, Bulletproof MCT oil does not contain lauric acid because it is a highly refined product designed for optimal and rapid ketone production. The manufacturer removes the slower-metabolizing C12 fatty acid to concentrate the more efficient C8 and C10 molecules. This makes Bulletproof MCT an excellent choice for targeted energy and cognitive support, particularly for individuals following a ketogenic diet. While lauric acid has its own unique health properties and is abundant in its source (coconut oil), its exclusion is a feature, not a drawback, of the Bulletproof formulation, specifically engineered for high-performance use.
