Introduction
If you have ever stared at a supplement label and felt like you needed a chemistry degree to understand the ingredients, you are not alone. Standing in the aisle or scrolling through pages of options, the codes "C8" and "C10" appear everywhere on MCT oil bottles. These are not just random numbers; they represent specific types of medium-chain triglycerides that dictate how your body produces energy and handles digestion.
At BUBS Naturals, we focus on providing clean, effective fuel that supports an active lifestyle without the confusion. Whether you are prepping for a morning ruck, looking to clear the mental fog before a big meeting, or supporting your gut health, the specific profile of your MCTs matters. Not all medium-chain fats act the same once they enter your system.
This guide will break down the science behind C8 and C10 to help you decide which is right for your goals. We will cover how these fats are metabolized, the specific benefits of each carbon chain, and why the delivery method—whether it is a liquid or a powder—can change your experience. By the end, you will know exactly how to choose the right fuel for your mission.
Understanding the Basics of MCTs
To understand which MCT oil is best, we need to look at what a triglyceride actually is. A triglyceride is the technical term for a fat molecule. It consists of a glycerol "backbone" with three fatty acid "tails" attached to it. The length of these tails is determined by the number of carbon atoms they contain.
Most fats in the modern diet, like those found in avocados, olive oil, or a steak, are long-chain triglycerides (LCTs). These usually have 13 to 21 carbon atoms. Because these tails are long, your body has to work hard to break them down. They require bile from your gallbladder and enzymes from your pancreas. After that, they travel through your lymphatic system before your body can use them for fuel or store them as fat.
Medium-chain triglycerides (MCTs) are shorter, typically ranging from 6 to 12 carbons. Because they are shorter, they skip the heavy lifting of traditional digestion. They go straight from your gut to your liver via the portal vein. This is essentially a metabolic "HOV lane" that allows the liver to convert these fats into ketones almost immediately. Ketones are an efficient fuel source that your brain and muscles can burn for energy without the blood sugar spikes associated with carbs.
Quick Answer: C8 (Caprylic acid) is generally considered the "best" for rapid ketone production and immediate mental clarity. However, a C8 and C10 blend is often better for daily wellness, sustained energy, and easier digestion for those with sensitive stomachs.

C8: The High-Octane Speedster
C8, also known as caprylic acid, is widely regarded as the premium choice for performance. It has eight carbon atoms in its chain. Because it is shorter than C10, your liver can process it faster than almost any other fat.
Rapid Ketone Production
When you consume C8, it converts into ketones in a matter of minutes. If you are following a ketogenic diet, this is a massive advantage because it helps maintain a state of ketosis even if you have had a few extra grams of carbohydrates. For those not on a keto diet, C8 still provides a "clean" energy hit that does not rely on glucose, helping you avoid the afternoon crash.
Cognitive Performance and Focus
One of the most cited reasons for using pure C8 is the "lifting of the fog." Ketones can cross the blood-brain barrier, providing the brain with an alternative to its usual glucose fuel. Many people find that ketones from C8 support better focus and mental stamina during demanding tasks. It is essentially brain fuel that does not require a insulin spike to work.
Antimicrobial Support
Beyond energy, C8 has natural antibacterial properties. It may help maintain a healthy balance in the gut microbiome by targeting harmful bacteria without disrupting the beneficial ones. This makes it a dual-purpose supplement: it fuels the body while supporting the internal environment.
C10: The Steady Burner and Gut Guardian
C10, or capric acid, contains ten carbon atoms. While it takes slightly longer to process than C8, it is still a medium-chain fat and far more efficient than the LCTs found in common cooking oils. It is often overlooked, but it brings unique benefits to the table that C8 does not emphasize.
Sustained Energy Levels
Because C10 is a slightly longer chain, the liver takes a bit more time to break it down. Think of C8 as a quick-burning tinder that gets the fire going, while C10 is the sturdy log that keeps the heat consistent. For many, a dose of C10 leads to energy that feels more leveled out over several hours.
Antifungal and Immune Benefits
One of the standout features of C10 is its potent antifungal properties. Research has shown that C10 is particularly effective against Candida albicans, a common yeast that can cause digestive issues when it grows out of balance. By helping to keep yeast and fungal populations in check, C10 supports a resilient immune system and smoother digestion.
Mitochondrial Support
Some studies suggest that C10 may support mitochondrial biogenesis—the process by which your cells create more mitochondria. Since mitochondria are the powerhouses of your cells, having more of them (and having them function efficiently) is a key part of long-term metabolic health and energy production.
Key Takeaway: C8 is built for speed and mental sharpness, making it the "performance" MCT. C10 is built for duration and gut resilience, acting as the "wellness" MCT. Most high-quality supplements blend the two to provide a full spectrum of benefits.

Choosing between pure C8 and a C8/C10 blend depends on what you are trying to achieve on a daily basis. There is no "wrong" choice, but there is usually a "better" choice for your specific lifestyle.
For Peak Performance and Training
If your primary goal is to fuel a high-intensity workout or stay sharp for a high-stakes presentation, a high-concentration C8 oil is often the winner. Its ability to provide near-instant ketones makes it the preferred tool for athletes and professionals who need to perform at their limit.
For more context on using MCTs for training and ketogenic routines, read this guide to choosing MCT oil for keto.
For Daily Wellness and Weight Management
If you are looking for a supplement that supports general longevity, consistent energy, and metabolic health, a C8/C10 blend is often superior. The combination ensures you get the quick mental boost from the C8 and the antifungal, immune-supporting, and thermogenic benefits of the C10. Most high-performing blends use a 60/40 or 70/30 split of C8 to C10.
For Beginners and Sensitive Stomachs
MCT oil is famous for a side effect known as "disaster pants"—the digestive urgency that happens when you take too much too fast. C8 is very potent and can be harsh on a sensitive stomach if you are not used to it. A blend that includes C10 is generally perceived as gentler on the digestive tract, making it the logical starting point for someone new to supplemental fats.
| Feature | C8 (Caprylic Acid) | C10 (Capric Acid) |
|---|---|---|
| Carbon Atoms | 8 | 10 |
| Metabolic Speed | Fastest conversion | Fast conversion |
| Primary Goal | Focus & Fast Ketones | Sustained Energy & Gut Health |
| Ketone Yield | Very High | High |
| Digestibility | Potent (Start slow) | Gentler |
The Role of C12 (Lauric Acid)
When researching MCTs, you will inevitably run into C12, or lauric acid. While technically classified as a medium-chain triglyceride, C12 behaves much more like a long-chain triglyceride once it enters your body.
About 70% to 80% of C12 is processed through the liver like an LCT, meaning it goes through the slower digestion process involving bile and the lymphatic system. While C12 is great for its antimicrobial benefits—it is the primary fat in whole coconut oil—it is not an efficient source of quick energy. This is why high-quality MCT oils and powders, like those we produce at BUBS Naturals, filter out C12. We focus on the "true" MCTs (C8 and C10) to ensure you get the rapid energy boost you are looking for.

Liquid vs. Powder: The Delivery Matters
Once you have decided on the C8 and C10 ratio, you have to decide on the format. Historically, MCT oil only came in a liquid form, but MCT oil powder has become the preferred choice for many active people.
The Benefits of MCT Oil Powder
MCT powder is created through a process called spray drying, where the oil is bound to a carrier. Our MCT Oil Creamer uses a high-quality C8/C10 blend and binds it to a prebiotic fiber. This format offers several advantages:
- Easier Digestion: Because the oil is bound to a fiber, it is released more slowly in the gut. This significantly reduces the risk of stomach upset compared to pure liquid oil.
- Mixability: Liquid oil can leave an oily film on top of your coffee or shake. A powder mixes into a creamy consistency, making it much more palatable in your morning routine.
- Portability: Carrying a bottle of oil is messy and prone to leaks. A powder is easy to toss into a gym bag or a suitcase when you are traveling.
For a richer option in the same format, consider the Butter MCT Oil Creamer.
Myth: MCT oil is just extra calories that will make you gain weight. Fact: Because MCTs are processed directly by the liver, they are far more likely to be burned as immediate energy than stored as body fat. They have also been shown to increase satiety, helping you feel full for longer and potentially reducing overall calorie intake.
How to Add C8 and C10 to Your Routine
If you are new to the world of MCTs, the most important rule is to start slow. Your gut needs time to adapt to the rapid influx of medium-chain fats.
The Dosing Protocol
Start with a small amount—about one teaspoon of liquid or half a scoop of powder. Use this dose for three or four days to see how your body reacts. If you do not experience any digestive discomfort, you can gradually increase to a full tablespoon or a full scoop. Most people find their "sweet spot" at one to two servings per day.
Optimal Timing
- Morning: Adding MCTs to your morning coffee is the gold standard. It provides steady energy to get you through the morning without a carb-heavy breakfast that might make you sluggish.
- Pre-Workout: Take your MCTs about 30 to 45 minutes before exercise. This gives your liver enough time to produce the ketones your muscles can use for fuel during the session.
- During Fasts: Many people use MCTs during intermittent fasting. While they do contain calories, they do not cause a significant insulin response. This allows many of the metabolic benefits of fasting to continue while providing the brain with the energy it needs to stay productive.

Sourcing and Quality: Why Coconut Is King
Not all MCT products are created with the same standards. When you are looking for the best MCT oil, you need to look beyond the C8 and C10 labels.
Coconut vs. Palm Oil
MCTs are typically sourced from either coconut oil or palm oil. While they are chemically similar, the palm oil industry is often linked to significant environmental destruction and deforestation. At BUBS Naturals, we use 100% coconut-sourced MCTs because it is a more sustainable path and results in a cleaner end product.
Clean Extraction
Look for products that are extracted through physical processes rather than chemical ones. Some lower-quality brands use harsh solvents like hexane to separate the MCTs. A premium product will use steam distillation or other clean methods to ensure no chemical residue remains in the oil or powder you are consuming.
Third-Party Testing
Trust is everything, especially when you are an athlete or a veteran who needs to know exactly what is going into your body. We ensure our products are third-party tested and NSF for Sport certified. This means what is on the label is exactly what is in the jar—no fillers, no banned substances, and no BS.
Note: If you have a history of liver issues or specific fat-malabsorption concerns, consult with your healthcare provider before adding high doses of MCT oil to your diet.

Conclusion
Determining which MCT oil is best for you comes down to your personal mission. If you are chasing a new PR or need to stay laser-focused during a grueling workday, a pure C8 oil will give you that rapid ketone boost. If you are looking for a daily supplement to support your gut health, immune system, and steady energy levels, a balanced blend of C8 and C10 is the superior way to go.
Regardless of the ratio, the foundation should always be quality. Stick to coconut-sourced fats, avoid chemical fillers, and start with a manageable dose to let your body adapt.

FAQ
Is C8 or C10 better for fat loss?
C8 is often the preferred choice for fat loss because it converts most rapidly into ketones, which are highly effective at suppressing appetite and increasing satiety. However, C10 also supports metabolic health through thermogenesis, so a blend of both C8 and C10 is usually the most effective for supporting overall body composition goals.
Can I take MCT oil every day?
Yes, most people can safely take MCT oil or powder every day as part of a balanced diet. It serves as a clean, efficient source of healthy fats that supports brain function and energy levels. Just remember to start with a small dose and increase slowly to ensure your digestive system adapts comfortably.
Does MCT oil break a fast?
While MCT oil contains calories, it does not cause a rise in blood sugar or a significant insulin spike. For those practicing intermittent fasting for weight loss or mental clarity, MCT oil is generally considered "fast-friendly" because it helps maintain a fat-burning state while providing the brain with energy to stay focused.
What is the difference between MCT oil and regular coconut oil?
Coconut oil is a whole food that contains all four types of MCTs, but it is mostly C12 (lauric acid), which digests slowly like a long-chain fat. MCT oil is a concentrated extract that removes the slower-digesting fats and the solids, leaving only the fast-acting C8 and C10 fatty acids for immediate energy.
