Introduction

You’ve probably seen MCT oil mentioned in locker rooms, on keto blogs, or added to your favorite morning coffee. Most people know it as a clean source of fat that helps with energy and focus, but when you start looking at the labels, things get technical. You see labels for "Pure C8" or "C8 and C10 Blend," and suddenly a simple health habit feels like a chemistry project.

MCT stands for medium-chain triglycerides. These are specific types of fats that your body processes differently than the long-chain fats found in a steak or a piece of cheese. At BUBS Naturals, we believe that understanding what you put in your body is just as important as the training you do. This guide will break down the differences between C8 and C10, how they work in your system, and which one you should reach for based on your goals.

Whether you want immediate mental clarity for a big meeting or sustained energy for a long trail run, the specific type of MCT you choose matters. We’re going to look at the science, the benefits, and the best ways to use these fats in your daily life.

Quick Answer: The primary difference is speed and function. C8 (caprylic acid) converts into ketones almost instantly, making it the best choice for rapid brain fuel and mental clarity. C10 (capric acid) takes slightly longer to process but provides sustained energy and offers significant antifungal and immune-supporting benefits.

What Exactly Are Medium-Chain Triglycerides?

To understand the difference between C8 and C10, we first need to look at what a triglyceride actually is. Most of the fats we eat are long-chain triglycerides (LCTs). These have 13 to 21 carbon atoms in their "tails." Because these tails are so long, your body has to go through a rigorous digestion process to break them down. They require bile from your gallbladder and enzymes from your pancreas to be absorbed into your lymphatic system before they ever reach your bloodstream.

Medium-chain triglycerides are different. They have shorter tails, ranging from 6 to 12 carbon atoms. This shorter length is a shortcut for your metabolism. Instead of going through the slow digestive process, MCTs are sent straight to your liver via the portal vein.

Once they hit the liver, they are rapidly converted into ketones. Ketones are an alternative fuel source to glucose (sugar). Your brain and muscles can use ketones for energy very efficiently, which is why MCT oil is so popular for people looking for a "clean" energy hit without the crash associated with sugar or excessive caffeine.

The four main types of MCTs are:

  • C6 (Caproic acid)
  • C8 (Caprylic acid)
  • C10 (Capric acid)
  • C12 (Lauric acid)

While all four are technically medium-chain fats, C8 and C10 are the two most sought-after for performance and health. C6 often tastes bad and can cause stomach issues, while C12 behaves more like a long-chain fat in the body.

C8 MCT Oil: The Speedster for Brain Energy

C8, or caprylic acid, is often called the "gold standard" of MCTs. It gets its name from its eight-carbon tail. Because it is the shortest of the "good" MCTs, it is the easiest for your body to break down.

When you consume C8, it bypasses the normal fat digestion process almost entirely. Within minutes, your liver converts it into ketones. These ketones can then cross the blood-brain barrier. This is why many people report a "lifting of the fog" shortly after taking a high-quality C8 supplement. It provides a direct, high-octane fuel source for your neurons.

Rapid Ketone Production

Research shows that C8 is about three times more ketogenic than C10 and about six times more ketogenic than C12. This means that if your goal is to stay in deep ketosis or to get a quick burst of energy before a workout, C8 is your most efficient tool. It produces the highest rise in blood ketones per calorie consumed.

Digestive Comfort

Because C8 is processed so quickly, it is often easier on the stomach than lower-quality MCT blends. While any oil can cause "disaster pants" if you take too much too soon, C8 is generally the most stable for people with sensitive digestive tracts.

Antibacterial Properties

Beyond energy, C8 has shown an ability to help manage internal health. Some studies suggest it can help reduce gut inflammation by suppressing specific proteins that trigger inflammatory responses. It also has natural antibacterial properties, which may support a healthier balance of bacteria in your digestive system.

C10 MCT Oil: Sustained Energy and Gut Health

C10, or capric acid, has ten carbon atoms. It is slightly longer than C8, which means it takes just a little bit longer for your liver to process it into energy. Don't let that "slowness" fool you into thinking it's inferior. In the world of wellness and adventure, sustained effort is often just as important as a quick sprint.

The "Slow Burn" Effect

If C8 is an espresso shot, C10 is more like a well-timed meal. It still converts to ketones much faster than traditional fats, but the process is slightly more gradual. This can help provide a more sustained energy curve, preventing the "peak and valley" feeling that can sometimes happen with rapid-fire energy sources.

Antifungal Powerhouse

C10 is most famous for its antifungal properties. It is particularly effective against Candida albicans, a type of yeast that lives in the gut. When Candida grows out of control, it can lead to bloating, brain fog, and digestive distress. Research has shown that C10 can rapidly break down the cell walls of these yeast strains, helping to keep your gut microbiome in check.

Immune Support

C10 has also been studied for its role in supporting the immune system. Because it has antimicrobial properties, it can help the body defend against certain viruses and harmful bacteria. Interestingly, research on breastfeeding mothers found that those who supplemented with C10-rich fats passed those antimicrobial benefits on to their infants, suggesting that the body prioritizes these fats for protection and development.

Key Takeaway: C8 is the most efficient fat for rapid ketone production and cognitive performance. C10 is slightly slower to metabolize but offers superior antifungal benefits and gut health support. Together, they provide a comprehensive energy and wellness profile.

C8 vs. C10: A Head-to-Head Comparison

Choosing between C8 and C10 depends entirely on what you are trying to achieve on a given day. Most high-quality supplements use a blend of both to give you the best of both worlds.

Feature C8 (Caprylic Acid) C10 (Capric Acid)
Carbon Tail Length 8 Carbons 10 Carbons
Digestion Speed Very Fast Fast
Ketone Output Highest Moderate
Primary Benefit Mental Clarity & Brain Fuel Gut Health & Immune Support
Metabolic Target Immediate Energy Sustained Energy
Sourcing Coconut or Palm Coconut or Palm

For the athlete, C8 is the pre-workout boost. It’s the energy you need when you’re pushing for a personal record or tackling a steep climb. For the person focused on longevity and daily wellness, the inclusion of C10 helps maintain a healthy gut and provides a more leveled-out energy experience throughout the workday.

The Role of C12 (Lauric Acid)

You might wonder why we don't talk as much about C12, or lauric acid. C12 makes up about 50% of the fat in raw coconut oil. While it is technically classified as a medium-chain triglyceride, it doesn't behave like one once it enters your body.

Because it has 12 carbons, it is just long enough that your liver can't process it all at once. A large portion of C12 follows the same slow digestive path as long-chain fats. It goes through the lymphatic system and is more likely to be stored as fat or used for slow energy rather than being converted into immediate ketones.

This is why eating a spoonful of coconut oil doesn't give you the same mental "kick" as a concentrated MCT oil. Coconut oil is great for cooking and has its own antimicrobial benefits thanks to the lauric acid, but for performance and ketosis, you want to focus on the C8 and C10 fractions.

Myth: Coconut oil and MCT oil are the same thing. Fact: While MCT oil is derived from coconut oil, they are very different. Coconut oil is mostly C12 (lauric acid), which behaves like a long-chain fat. MCT oil is a concentrated extract of C8 and C10, which provide rapid energy and ketone production.

Why We Use a C8/C10 Blend

At our core, we believe in products that support a lifestyle of adventure and purpose. We don't believe in "filler" ingredients. When you look at a product like our MCT Oil Creamer, you’re getting a clean, coconut-sourced powder designed to mix effortlessly.

We choose to use a blend of C8 and C10 because it mirrors the benefits found in nature while concentrating them for performance. By combining the rapid energy of C8 with the gut-supporting and sustained energy of C10, we create a supplement that works for your whole day, not just the first thirty minutes.

Our MCT products are also third-party tested and NSF for Sport certified. This is a critical distinction. For athletes, veterans, and anyone who takes their health seriously, knowing that a product is free of banned substances and contaminants is non-negotiable. We use a "no BS" approach—no fillers, no maltodextrin, and no artificial sweeteners. We use acacia fiber as a carrier for our powders, which acts as a prebiotic to further support the gut health benefits provided by the C10.

How to Incorporate C8 and C10 Into Your Routine

Adding MCT oil to your life doesn't have to be complicated. The goal is to make it a friction-less part of your existing habits.

The Morning Kickstart

The most common way to use MCT is in coffee. By mixing our Butter MCT Oil Creamer into your morning cup, you’re providing your brain with a source of ketones right as you start your day. This is especially effective if you practice intermittent fasting, as the healthy fats can help keep you satiated without causing a significant spike in insulin that would break your fast.

Pre-Workout Fuel

If you have a long training session ahead, a scoop of MCT powder in a protein shake or even just water can provide a steady stream of fuel. Unlike sugar-based pre-workouts that lead to a crash, MCTs offer a stable burn. Many endurance athletes report that using MCTs helps them "tap into" their body's fat stores more effectively during long efforts.

Mid-Day Mental Reset

If you hit that 2:00 PM slump where your brain feels like it’s running through mud, C8 can be a lifesaver. Instead of reaching for a third cup of coffee or a sugary snack, a serving of MCT oil can provide the ketones your brain needs to sharpen its focus and finish the workday strong.

Smoothies and Shakes

Because our MCT powder is flavorless (or comes in a rich, buttery flavor), it’s easy to toss into a blender with some greens, protein, and Collagen Peptides. This creates a balanced meal that supports your joints, muscles, and energy levels all at once.

Note: If you are new to MCT oil, start small. Begin with half a serving (about a teaspoon) to let your digestive system adjust. Gradually work your way up to a full tablespoon over a week or two. Taking too much too fast can lead to temporary stomach upset.

Sourcing Matters: Coconut vs. Palm Oil

Not all MCT oils are created equal. Many cheaper brands source their MCTs from palm oil. The palm oil industry is a major driver of deforestation and habitat destruction in many parts of the world.

We are committed to doing things the right way. Our MCTs are sourced 100% from coconuts. This isn't just about being "green"—it's about quality. Coconut-sourced MCTs tend to have a cleaner taste and a better fatty acid profile. By choosing coconut-based products, we ensure that our impact on the planet is as positive as our impact on your health.

We also use a triple-steam distillation process. This is a chemical-free way to separate the C8 and C10 from the rest of the coconut oil. No hexanes, no harsh solvents—just heat and pressure. This results in a pure, stable oil that doesn't have a "coconutty" aftertaste and won't go rancid easily.

The Connection to Recovery and Wellness

While energy is the headline benefit of C8 and C10, we shouldn't overlook their role in recovery. Training hard puts a lot of stress on the body. This stress can lead to inflammation and a taxed immune system.

By supporting gut health with C10 and reducing systemic inflammation with C8, you’re giving your body the tools it needs to recover faster. When your gut is healthy, you absorb nutrients from your food more effectively. When your brain is fueled by ketones, your central nervous system can recover more efficiently from the strain of heavy lifting or high-intensity intervals.

We often suggest pairing MCT with our Collagen Peptides. While the MCT provides the energy to perform and the gut support to stay healthy, the collagen provides the amino acids necessary to repair joints, tendons, and skin. It's a holistic approach to wellness: fuel the engine, then fix the frame.

Listening to Your Body

At the end of the day, wellness isn't about following a strict set of rules—it's about finding what works for your unique body. Some people find they perform best on pure C8. Others prefer the balanced approach of a C8 and C10 blend.

Listen to how you feel. Do you feel more focused? Is your energy stable throughout the day? Is your digestion smooth? Use these as your markers of success. We design our products to be versatile so you can experiment and find the "sweet spot" for your routine.

Whether you're a professional athlete, a weekend warrior, or someone just trying to keep up with a busy family, the goal is the same: to show up as the best version of yourself. Clean, science-backed nutrition is a foundational piece of that puzzle.

Bottom Line: Which One Wins?

There is no "winner" in the battle of C8 vs. C10. Instead, think of them as specialized tools in your kit.

C8 is your go-to for high-performance moments. It is the fastest, most ketogenic option for anyone looking for an immediate brain boost or an athletic edge. If you want the most "bang for your buck" in terms of ketone production, C8 is the clear choice.

C10 is your long-term health partner. Its antifungal and immune-supporting properties make it essential for anyone focused on gut health and metabolic longevity. It provides a slightly more gradual energy release that complements the speed of C8.

By using a blend that features both, you’re not choosing one benefit over the other. You’re getting a comprehensive supplement that supports your brain, your gut, and your energy levels from the moment you wake up until your head hits the pillow.

Our mission is to provide you with the cleanest, most effective tools to live a life of adventure. We were built on the legacy of Glen "BUB" Doherty, a man who lived with purpose and intensity. That spirit is in every product we make. When you choose our MCT products, you’re not just buying a supplement—you’re joining a community dedicated to doing better and giving back.

FAQ

Is C8 better than C10 for weight loss?

C8 is generally considered more effective for weight management because it is more ketogenic. Higher ketone levels can help suppress the hunger hormone ghrelin and increase satiety, making it easier to stick to a healthy eating plan. However, C10 supports gut health, which is also a critical factor in long-term metabolic health and weight maintenance.

Can I take MCT oil if I'm not on a keto diet?

Absolutely. You don't need to be in nutritional ketosis to benefit from C8 and C10. Even if you eat carbohydrates, your liver will still process the MCTs into ketones, providing an immediate energy source for your brain and muscles. Many people use MCT oil simply for the mental clarity and steady energy it provides, regardless of their overall diet.

Why does MCT oil sometimes cause an upset stomach?

MCTs are absorbed very quickly, which can sometimes overwhelm the digestive tract if you aren't used to them. This is often called "gastric distress." To avoid this, we recommend starting with a small dose—roughly one teaspoon—and slowly increasing it over two weeks. Using a powder form, like our MCT Oil Creamer, is often gentler on the stomach than pure liquid oil.

Should I use MCT oil or coconut oil in my coffee?

If your goal is energy and focus, MCT oil is the superior choice. Coconut oil is about 50% lauric acid (C12), which is slow to digest and doesn't produce many ketones. Our MCT products are concentrated versions of the C8 and C10 found in coconut oil, giving you a much higher "dose" of the fats that actually drive performance and mental clarity.
