Introduction

If you have ever looked at a bottle of MCT oil, you probably noticed some chemical-looking shorthand like C8 or C10 on the label. For most people, these numbers feel more like high school chemistry than high-performance nutrition. However, understanding these differences is the key to getting the most out of your morning coffee or pre-workout shake.

At BUBS Naturals, we believe that knowing what you put in your body is just as important as the work you put in at the gym. This guide will break down the science of medium-chain triglycerides, explain why C8 and C10 are the gold standard for energy, and help you decide which one fits your specific goals. Our goal is to provide clear, actionable information so you can choose the right supplements for your active lifestyle.

By the end of this article, you will understand the metabolic differences between these fatty acids and how they support your brain and body.

Quick Answer: C8 (caprylic acid) and C10 (capric acid) are types of medium-chain fats found in coconut oil. C8 is known for its ability to convert rapidly into ketones for immediate brain and body fuel, while C10 provides a slightly slower, more sustained energy source along with immune and digestive support.

Understanding the Basics of MCTs

To understand what C8 and C10 are, we first need to look at what MCT stands for: medium-chain triglycerides. Triglyceride is simply the technical name for fat. Most of the fats you eat in a standard diet, like olive oil, avocado, or animal fats, are long-chain triglycerides (LCTs).

The "chain" refers to a string of carbon atoms. Think of these carbon atoms like a tail. LCTs have long tails, usually 13 to 21 carbons long. 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 to digest. After that, they travel through your lymphatic system before they can be used for energy or stored as fat.

MCTs are different. They have shorter tails, ranging from 6 to 12 carbons. Because the chains are shorter, they are much easier for your body to process. Instead of going through the long digestion process, they go straight to your liver via the portal vein. This allows them to be used almost immediately as a clean energy source.

If you want to see how that shows up in a real product, our MCT Oil Creamer is built around that fast-acting format.

What is C8 (Caprylic Acid)?

C8 is the shorthand for caprylic acid. It gets its name because it has a chain of exactly eight carbon atoms. Among the different types of MCTs, C8 is often considered the most desirable for those looking for a fast energy boost.

Because it has a very short chain, your body can break it down almost instantly. Once it reaches the liver, it is converted into ketones. Ketones are molecules produced when your body burns fat for fuel instead of glucose (sugar). These ketones can cross the blood-brain barrier, providing an immediate energy source for your brain. This is why many people report feeling a sense of mental clarity and focus shortly after taking a supplement high in C8.

Our MCT products prioritize these efficient fats because they support the needs of athletes and busy professionals who need to stay sharp. C8 is effectively the "speedster" of the fat world. It does not spend much time being processed; it gets straight to work.

The Specific Benefits of C8

While energy is the primary reason people seek out C8, it offers several other advantages:

• Rapid Ketone Production: Research suggests that C8 produces significantly more ketones per gram than other MCTs. This makes it a favorite for those following a ketogenic or low-carb diet.
• Gut Health Support: C8 has natural antibacterial properties. It may help balance the bacteria in your gut by keeping "bad" microbes in check.
• Reduced Inflammation: Some studies indicate that C8 may help suppress certain proteins that trigger intestinal inflammation, which can lead to smoother digestion.

Key Takeaway: C8 is the most metabolically active MCT. It bypasses traditional digestion to provide a quick spike in ketone levels, making it ideal for immediate mental focus and physical energy.

What is C10 (Capric Acid)?

C10, or capric acid, has a chain of ten carbon atoms. It is slightly longer than C8, which means it takes a tiny bit longer for your liver to process. However, it is still significantly faster than any long-chain fat you would find in common cooking oils.

If C8 is the sprinter, C10 is the middle-distance runner. It provides a more sustained release of energy. Many high-quality MCT oils use a blend of C8 and C10 to give you both the immediate "kick" and the lasting fuel to get through a long morning or a tough training session.

The Specific Benefits of C10

C10 has a unique set of benefits that complement the fast-acting nature of C8:

• Immune Support: C10 is well-regarded for its antifungal and antimicrobial properties. It has been shown in some studies to be effective at fighting off certain types of yeast and fungi, like Candida, in the digestive tract.
• Metabolic Support: Like C8, C10 is rarely stored as fat. It is prioritized for energy production, which can help support a healthy metabolism.
• Synergy with C8: When taken together, C10 helps balance the rapid absorption of C8, potentially reducing the likelihood of the "disaster pants" (digestive upset) that some people experience when taking high doses of pure C8 for the first time.

C8 vs. C10: A Comparison

When choosing a supplement, you might wonder if you should hunt for 100% pure C8 or stick with a blend. The right choice usually depends on your specific goals and how your body reacts to fats.

Most people find that a blend of C8 and C10 offers the best of both worlds. We use a carefully balanced ratio in our Butter MCT Oil Creamer to ensure you get that mental lift without the energy crash later.

Myth: You need 100% C8 MCT oil to see any results.
Fact: While C8 is the fastest for ketone production, a blend of C8 and C10 provides a more well-rounded approach to energy and immune health, often at a more accessible price point.

What About C6 and C12?

You might notice that we skipped C6 and C12. While these are technically medium-chain fats, they are rarely found in high-quality MCT supplements for good reason.

C6 (Caproic Acid)

C6 is the shortest MCT, but it has two major downsides: it tastes terrible and it often causes immediate digestive distress. Most people describe the taste as "goaty" or "acidic." Because of these issues, reputable brands filter C6 out during the manufacturing process.

C12 (Lauric Acid)

C12 makes up about 50% of the fat in coconut oil. While it is technically an MCT, it behaves much more like a long-chain triglyceride in the body. It does not go straight to the liver; instead, it goes through the slower lymphatic digestion process. C12 is great for its antimicrobial properties, but it is not the ingredient you want if your goal is rapid energy or ketone production. This is why "liquid coconut oil" is not the same thing as a true MCT oil.

For a deeper look at that difference, see our guide on MCT Oil and Coconut Oil vs. MCT Oil Powder.

MCT Oil vs. Coconut Oil

A common point of confusion is whether you can just eat a spoonful of coconut oil and get the same results as using a refined MCT oil. The answer is no, not quite.

Coconut oil is a whole food. It contains a mix of all the MCTs (C6, C8, C10, and C12) plus some long-chain fats. As mentioned, the vast majority of the "MCTs" in coconut oil are actually C12. If you want the specific benefits of C8 and C10—the rapid energy and the mental clarity—you would have to eat a massive amount of coconut oil to get an effective dose.

MCT oil is a concentrated supplement created through a process called fractionation. This involves heating the oil to separate the different fatty acids based on their boiling points. This allows us to pull out the C8 and C10 and leave the slower-digesting C12 behind. At BUBS Naturals, we use a clean extraction process to ensure our MCT oil is free of fillers and chemicals.

How Your Body Uses C8 and C10

To appreciate why these fats are so popular in the fitness community, you have to understand the metabolic path they take.

When you consume C8 or C10, they travel through the stomach and enter the small intestine. Because they are medium chains, they don't need to be broken down by bile. They pass through the intestinal wall and enter the portal vein, which leads directly to the liver.

In the liver, the body has a choice: use the fat for energy or store it. Because C8 and C10 are so "accessible," the liver almost always chooses to burn them immediately. This process produces ketones.

Ketones are an incredibly efficient fuel source. For the brain, they provide a steady stream of energy that does not rely on blood sugar levels. This is why many people who practice intermittent fasting use MCT oil in the morning. It provides energy to the brain without "breaking" the metabolic state of fasting or causing an insulin spike.

Bottom line: C8 and C10 are processed differently than other fats, moving straight to the liver to be converted into ketones for immediate use by the brain and muscles.

Practical Benefits for an Active Lifestyle

Why should you care about carbon chain lengths when you're out on a trail or heading into the office? It comes down to how your body manages energy over time.

Sustained Mental Focus

Your brain is the most energy-hungry organ in your body. While it usually runs on glucose, it can actually run more efficiently on ketones. Many people find that a morning dose of MCTs helps them avoid the "afternoon slump" that follows a high-carb breakfast. By providing the brain with C8 and C10, you are giving it a backup fuel source that keeps your focus sharp even when you haven't eaten in a few hours.

Training and Endurance

For athletes, C8 and C10 can serve as a "glycogen sparer." Your body has a limited supply of stored carbohydrates (glycogen). Once those run out, you hit the proverbial "wall." By taking MCTs before or during a long session, you provide your body with an alternative energy source that it can burn alongside its glycogen stores. This may help you go longer or push harder before fatigue sets in.

If you are curious how these kinds of performance-supporting ingredients fit into a broader routine, our Creatine Monohydrate is another clean option in the Boosts Collection.

Appetite Management

Fats are naturally satiating, but MCTs have a special edge. Some studies suggest that C8 and C10 can help trigger the release of hormones that tell your brain you are full. If you find yourself constantly snacking or feeling "hangry" between meals, adding these fats to your diet may help you feel satisfied for longer.

How to Use C8 and C10 in Your Routine

If you are new to the world of medium-chain triglycerides, the most important rule is to start slow. Because these fats are absorbed so quickly, taking too much at once can overwhelm your digestive system.

The "Low and Slow" Approach

Start with a small amount—about one teaspoon or half a scoop of powder. Use that for a few days and see how your stomach feels. If everything is fine, you can gradually work your way up to a full tablespoon or a full scoop. Most people find that 1-2 servings per day is the sweet spot for energy and focus.

Timing Your Intake

There are several ways to fit MCTs into your day:

• Morning Coffee: This is the most popular method. Stirring a scoop of MCT powder into your coffee creates a creamy, latte-like texture and provides a steady start to the day.
• Pre-Workout: Take a serving about 30 minutes before you train. It can give you a boost of energy that doesn't feel heavy in your stomach like a full meal might.
• Smoothies and Shakes: MCT oil is flavorless and odorless, making it an easy addition to any post-workout protein shake.
• Salad Dressings: You can use liquid MCT oil as a base for a healthy vinaigrette. Just remember not to cook with it at high temperatures, as it has a lower smoke point than oils like avocado or coconut oil.

Choosing a High-Quality MCT Supplement

Not all MCT oils are created equal. Since you're looking for the benefits of C8 and C10, you need to make sure the product you choose actually contains them in high concentrations.

First, check the source. You want MCTs derived from 100% coconuts. Some cheaper brands use palm oil, which is often linked to unsustainable environmental practices. Our commitment to quality means we only source from sustainable coconuts.

Second, look for purity. A good MCT oil should have no fillers, no artificial flavors, and no extra additives. If you are choosing a powder, make sure it is not packed with corn starch or maltodextrin, which can spike your blood sugar and defeat the purpose of taking MCTs in the first place. Our MCT Oil Creamer uses a clean base that mixes effortlessly without the junk.

Finally, consider the form. Liquid MCT oil is great for home use, but it can be messy and hard to travel with. MCT powder is often more convenient for those on the go. It is also generally gentler on the stomach for beginners because the oil is "micro-encapsulated" in a fiber base, which slows down the absorption just enough to prevent digestive upset.

FAQ

Is C8 better than C10?

It is not necessarily better, but it is faster. C8 is the most efficient at producing ketones, which makes it superior for immediate mental focus. However, C10 offers unique antimicrobial benefits and provides a more sustained energy release, so a blend of the two is often the best choice for most people.

Can I take MCT oil on an empty stomach?

Yes, many people take MCT oil on an empty stomach, especially those practicing intermittent fasting. However, if you are new to MCTs, this can sometimes cause stomach upset. It is best to start with a small amount or mix it into a drink to see how your body responds.

Does MCT oil help with weight loss?

While MCT oil is not a "magic pill" for weight loss, it can support your goals by promoting satiety and providing a clean energy source that the body is less likely to store as fat. When used as part of a balanced diet and active lifestyle, it may help you manage cravings and stay energized.

Why does some MCT oil cause stomach pain?

Because MCTs are absorbed so rapidly, they can sometimes cause a "flush" in the digestive system if you take too much too soon. This is especially true for pure liquid MCT oil. Starting with a smaller dose or using a powdered MCT, which is often gentler on the gut, can help prevent this issue.
