Introduction
If you have ever looked at a bottle of MCT oil, you have probably noticed some cryptic labels like "C8," "C10," or "Pure Caprylic Acid." It can feel like you need a chemistry degree just to pick a supplement for your morning coffee. Most people know that MCTs—or medium-chain triglycerides—are healthy fats that provide quick energy, but the nuance between the different types often gets lost in the noise.
At BUBS Naturals, we believe that understanding what you put into your body is just as important as the workout itself. Whether you are trying to stay sharp during a long afternoon of meetings or looking for an extra gear during a morning ruck, the specific type of MCT you choose can make a difference. This guide will break down the science of C8 and C10 so you can stop guessing and start fueling with intent.
The short answer is that neither is strictly "better" for everyone, but they do serve different roles. One acts like a quick-strike energy source, while the other offers a slower burn and specific health-protective benefits. Our goal is to help you figure out which one fits your specific lifestyle and performance goals.
What Are Medium-Chain Triglycerides?
To understand the difference between C8 and C10, we first have to look at what a medium-chain triglyceride actually is. In the world of nutrition, fats are categorized by the length of their carbon chains. Most of the fats we eat in a standard diet are long-chain triglycerides (LCTs), which have 13 to 21 carbon atoms. These take a long time for your body to break down and are often stored as body fat.
Medium-chain triglycerides (MCTs) are much shorter, containing between 6 and 12 carbon atoms. Because they are shorter, your body handles them differently. Instead of going through the slow process of being broken down by bile and stored, MCTs go straight to your liver. Once there, they are quickly converted into ketones—small molecules that serve as an alternative energy source to glucose (sugar). For a deeper look at the basics, explore this guide to what MCT oil is used for.
There are four main types of MCTs found in nature, mostly in coconut oil and palm oil:
- C6 (Caproic Acid): The shortest, but often removed because it tastes bad and can cause stomach issues.
- C8 (Caprylic Acid): The fastest to convert into energy.
- C10 (Capric Acid): A slightly slower energy source with immune-supporting properties.
- C12 (Lauric Acid): The longest, which behaves more like a traditional fat.
Key Takeaway: The "C" number refers to how many carbon atoms are in the fatty acid chain. The fewer carbons there are, the faster your body can turn that fat into usable energy (ketones).
Creamers
The Case for C8: Caprylic Acid
C8, or caprylic acid, is widely considered the gold standard for anyone seeking immediate mental and physical performance. It makes up about 6% to 7% of coconut oil, which is why pure C8 oils are more expensive—it takes a lot of coconuts to extract a single bottle.
Rapid Ketone Production
The primary reason people choose C8 is speed. Because it has only eight carbon atoms, it requires very little effort for your liver to process. Research suggests that C8 can produce several times more ketones than C10 or C12. If you are using MCT oil to support a ketogenic lifestyle or to clear "brain fog," C8 is usually the preferred choice.
Cognitive Focus
When your brain uses ketones for fuel instead of glucose, many people report a sense of "clean" energy. Unlike the spike and crash associated with sugar or excessive caffeine, ketones provide a steady stream of fuel for your neurons. This is why you often see C8 marketed as a "brain oil." It crosses the blood-brain barrier quickly, offering that mental sharpness you need when you are deep into a complex project or a demanding training session.
Digestive Comfort
While all MCT oils can cause a little "disaster pants" if you take too much too soon, C8 is generally easier on the stomach than the shorter C6. However, because it is so potent and moves so quickly into the liver, we always recommend starting with a small dose—usually a teaspoon—to let your system adjust.
The Case for C10: Capric Acid
C10, or capric acid, has ten carbon atoms. While it might not be as "fast" as C8, it brings its own set of unique advantages to the table that make it a valuable part of a wellness routine.
Sustained Energy
Because C10 is slightly longer than C8, it takes a little more time for the liver to process. This isn’t necessarily a bad thing. If C8 is a quick-burning piece of kindling, C10 is more like a solid log on the fire. It provides a more sustained release of energy, which can be helpful for endurance athletes or people who want to feel full and energized for several hours without a re-up.
Antifungal and Immune Support
One of the standout features of C10 is its antimicrobial and antifungal properties. Studies have shown that capric acid is particularly effective at fighting off certain types of yeast and fungi in the gut, such as Candida albicans. By supporting a healthy gut environment, C10 indirectly supports your immune system.
Metabolic Health
C10 has also been studied for its role in supporting metabolic health. Some research suggests it may help the body process fats more efficiently and support insulin sensitivity. While C8 gets all the glory for "instant energy," C10 does a lot of the heavy lifting for long-term health and internal balance.
QUICK ANSWER BOX
Quick Answer: C8 is generally better for rapid ketone production and immediate mental clarity, while C10 is better for sustained energy and gut health support. Most people benefit most from a blend of both, which provides a balanced energy profile and is often easier on the digestive system.

Is C12 Worth Your Time?
You might see some cheaper MCT oils that contain a high percentage of C12, also known as lauric acid. Lauric acid is the primary fatty acid in coconut oil (making up about 50%). While it is technically a medium-chain triglyceride, it behaves more like a long-chain triglyceride in the body.
C12 has to go through the stomach and be broken down by enzymes before it can be used, meaning it doesn't provide the "instant hit" of energy that C8 and C10 do. It is fantastic for skin health and has strong antiviral properties, but if your goal is performance, focus, or ketosis, a C12-heavy oil is going to underperform. That is why we focus our efforts on the shorter chains that actually move the needle for your energy levels.
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 is slow to digest. MCT oil is a concentrated extract of C8 and C10, providing much faster energy for the brain and muscles.
Why a Blend is Often the Best Choice
While "Pure C8" sounds impressive, it isn't always the best option for the average active person. For many, a blend of C8 and C10 provides a more comprehensive benefit profile. This is exactly why we designed our MCT Oil Creamer to be a balanced source of these functional fats.
1. The Full Spectrum of Energy
By combining C8 and C10, you get the best of both worlds. The C8 hits your system quickly, providing that immediate lift for your morning workout or your first block of work. As the C8 begins to taper off, the C10 is hitting its stride, providing the sustained fuel that carries you through to lunch.
2. Digestive Tolerance
Pure C8 is incredibly potent. For some people, especially those new to healthy fats, pure C8 can be a bit aggressive on the digestive tract. A blend is often much smoother on the stomach. It allows you to reap the benefits of ketone production without the risk of an urgent bathroom trip mid-run.
3. Cost-Effectiveness and Purpose
Pure C8 is expensive to produce. For most people—unless they are elite athletes or strictly managing a medical condition with ketosis—the incremental benefit of pure C8 over a high-quality blend doesn't always justify the price jump. A blend allows us to provide a high-performance product that people can actually afford to use every single day.
How to Use MCT Oil for Maximum Results
Knowing which oil to choose is only half the battle. You also need to know how to incorporate it into your lifestyle so it actually makes a difference in how you feel. This guide to MCT oil powder benefits covers additional ways to build it into your routine.
In Your Morning Coffee
This is the classic "power move." When you mix MCT oil or our MCT powder into coffee, the fat helps slow the absorption of caffeine. This leads to a more prolonged, stable energy boost rather than a jittery spike followed by a crash. Our Butter MCT Oil Creamer is a great option here, adding a rich, creamy texture without any added sugar or junk.
Pre-Workout Fuel
Because MCTs are processed so quickly, they make an excellent pre-workout energy source. About 30 minutes before you head to the gym or out for a trail run, try a serving of MCT. It provides your muscles with a source of fuel that doesn't require a heavy digestive load, meaning you won't feel weighed down while you move.
During Intermittent Fasting
Many people use MCT oil to extend their fasting windows. Because MCTs have a negligible effect on insulin levels, they can help you stay in a fat-burning state while providing enough energy to keep your brain functioning during those final hours of a fast. It helps suppress the "ghrelin" hormone—the one responsible for making you feel hungry—making it much easier to stick to your goals.
Important: If you are new to MCT oil, start with 1 teaspoon per day. Monitor how your body reacts for 3-4 days before increasing to a full tablespoon. Taking too much too soon can lead to stomach cramps or digestive upset.
Quality Matters: What to Look For
Not all MCT oils are created equal. The "is C8 or C10 better" debate doesn't matter if the oil you buy is full of fillers or sourced poorly. You can compare available formats in the BUBS creamers collection.
- Check the Source: Look for 100% coconut-sourced MCT oil. Some cheaper brands use palm oil, which is often associated with destructive environmental practices unless it is sustainably sourced. At BUBS, we stick to the clean stuff.
- Extraction Method: You want an oil that is extracted using steam distillation rather than harsh chemical solvents like hexane.
- Third-Party Testing: This is non-negotiable for us. Our products are NSF for Sport certified. This means they are tested for purity and banned substances, making them safe for everyone from professional athletes to weekend warriors.
- No Fillers: If you are buying a powder, check the label. Many brands use maltodextrin or corn syrup solids as carriers for the oil. We use organic acacia fiber, which acts as a prebiotic to support your gut health while keeping the powder easy to mix.
The Bottom Line on C8 vs C10
When you are weighing whether C8 or C10 is better, think about your "why."
If your primary goal is absolute peak mental performance for a high-stakes exam or an ultra-endurance event where you need the highest possible ketone levels, you might lean toward pure C8.
However, for 95% of people living an active, healthy lifestyle, a high-quality blend of C8 and C10 is the superior choice. It offers immediate energy, sustained fuel, gut health support, and better digestive tolerance. It is the "daily driver" of the supplement world—reliable, effective, and versatile.

FAQ
Is C8 MCT oil better for weight loss than C10?
Both C8 and C10 can support weight management by promoting satiety and helping the body stay in a fat-burning state. However, C8 is slightly more effective at boosting ketone production, which many people find helpful for suppressing appetite and reducing cravings for sugary snacks.
Can I cook with C8 or C10 MCT oil?
MCT oil has a relatively low smoke point, usually around 320°F (160°C). While you can use it for low-heat sautéing or as an ingredient in baking, it is best used as a "finishing oil." You will get the most benefit by stirring it into coffee, blending it into smoothies, or drizzling it over a salad after the heat has been turned off. For more ideas, explore this guide to MCT oil versus MCT oil powder.
Will C8 or C10 MCT oil break my fast?
Technically, any calorie-containing food breaks a fast, but MCT oil is often used in "fasting-mimicking" protocols. Because it does not cause a significant spike in blood sugar or insulin, it allows your body to remain in a ketogenic, fat-burning state. Most people find that the benefits of mental clarity and hunger suppression far outweigh the small number of calories consumed.
Does MCT oil cause stomach pain?
For some people, MCT oil can cause digestive issues like cramping or diarrhea if they take too much at once. This is because MCTs are absorbed so rapidly that they can draw water into the intestines. To avoid this, always start with a very small dose (one teaspoon) and gradually work your way up to a full serving over a week or two.
