Introduction
You’ve likely seen the letters and numbers C8, C10, and C12 on supplement labels while searching for a cleaner way to fuel your mornings. These aren't just scientific codes. They represent specific types of medium-chain triglycerides (MCTs) that change how your body creates and uses energy. When you understand the difference between these carbon chains, you can better tailor your nutrition to your performance goals.
At BUBS Naturals, we believe in keeping things simple and effective. Whether you are looking for a mental edge during a long shift or a quick boost before a training session, the specific MCTs in your oil matter. This guide breaks down the science behind these fats and explains how each one supports your lifestyle.
Our goal is to help you understand what these fatty acids are and why the specific blend you choose impacts your results. From rapid ketone production to gut health, the length of the carbon chain determines how the fat is metabolized. By the end of this article, you will know exactly which MCTs align with your needs.
Quick Answer: C8 (Caprylic), C10 (Capric), and C12 (Lauric) are fatty acids found in MCT oil, named for the number of carbon atoms in their chemical chains. C8 is the fastest for energy and ketone production, C10 supports gut health and immunity, while C12 acts more like a slow-burning fat with powerful antimicrobial properties.
The Science of Medium-Chain Triglycerides
Triglyceride is just a technical term for fat. These molecules have two primary jobs: they are either burned for immediate energy or stored for later use. Most of the fats in a standard diet are long-chain triglycerides (LCTs). These are found in foods like olive oil, avocado, and meat. LCTs have 13 to 21 carbon atoms and require a slow, complex digestion process.
Medium-chain triglycerides are different. They contain between 6 and 12 carbon atoms. Because these chains are shorter, your body handles them with much more efficiency. They do not require the same enzymes or bile to break down as longer fats. Instead of winding through your digestive system, MCTs go straight to your liver.
Once in the liver, your body can use these fats as an instant fuel source. They can also be converted into ketones. Ketones are small energy molecules that can cross the blood-brain barrier. This provides an alternative fuel source for the brain, which usually relies on glucose. This metabolic shortcut is why MCTs are highly valued by athletes and those following low-carb protocols.

Key Takeaway: The shorter the carbon chain of an MCT, the faster your liver can convert it into usable energy or ketones. This bypasses the traditional, slower fat digestion process.

C8: Caprylic Acid for Rapid Energy
C8, or caprylic acid, is often considered the gold standard for quick energy. It contains eight carbon atoms. It is the shortest of the three primary MCTs used in supplements (C6 is shorter but usually removed due to a foul taste). Because C8 is so short, it is the easiest for your body to break down and utilize.
When you consume C8, it converts into ketones almost instantly. Many people report feeling a sense of mental clarity and stable energy within minutes of adding it to their coffee. It is the most ketogenic of the MCTs. This means it creates the highest rise in blood ketones per gram compared to C10 or C12.
Aside from energy, C8 may support gut health. Some studies suggest it has antibacterial properties that help manage the balance of microbes in your digestive tract. It can also help reduce gut inflammation. For someone training hard or dealing with a high-stress lifestyle, a healthy gut is essential for overall recovery and performance.
Bottom line: C8 is the fastest-acting MCT and is best for those prioritizing mental focus, rapid ketone production, and immediate physical fuel.
C10: Capric Acid for Immunity and Gut Health
C10, or capric acid, has ten carbon atoms. While it is slightly slower to convert into energy than C8, it remains a fast-burning fuel source. It is often paired with C8 to provide a more balanced energy profile. C10 offers specific benefits that go beyond just fueling your muscles and brain.
The most notable feature of C10 is its powerful antifungal and antimicrobial properties. It has been shown to be effective against certain strains of yeast and fungi, including Candida albicans. Maintaining a healthy balance of yeast in the gut is crucial for digestion and immune function. If your gut is compromised, your energy levels and recovery will follow.
C10 also supports the immune system. Research indicates that capric acid can help the body fight off certain infections. It provides a secondary layer of protection while still serving as a clean, efficient fat source. When we formulated our products, we recognized that a healthy body needs more than just a quick spark; it needs a solid foundation of internal health.
Bottom line: C10 is a versatile MCT that supports sustained energy and offers robust antifungal and immune-boosting benefits.

Join The ClubC12: Lauric Acid and the Coconut Oil Debate
C12, or lauric acid, has twelve carbon atoms. It makes up about 50% of the fat found in natural coconut oil. While it is technically classified as a medium-chain triglyceride, it behaves more like a long-chain fat in the body. This is a point of confusion for many people looking at MCT supplements.
Because C12 is longer, it does not go straight to the liver as efficiently as C8 or C10. Instead, a large portion of it travels through the lymphatic system like other fats. This means it is slower to produce ketones and slower to provide an energy boost. If you are looking for "rocket fuel" for your brain, C12 is not the primary tool for the job.
However, C12 is not without merit. It is a potent antimicrobial agent. Once ingested, your body converts lauric acid into monolaurin. Monolaurin can help kill harmful pathogens like bacteria and viruses. This makes C12 excellent for general wellness and long-term health, which is why coconut oil is still a staple in many kitchens.
For more context, explore this comparison of coconut oil and MCT oil.
Myth: Coconut oil is the same thing as MCT oil.
Fact: Coconut oil contains MCTs, but it is mostly C12 (Lauric acid), which is slow to digest. Pure MCT oil concentrates the faster-acting C8 and C10 chains for more immediate benefits.
Comparing C8, C10, and C12
To choose the right product, you need to see how these fats stack up against one another. Most high-quality supplements focus on C8 and C10 because they provide the metabolic advantages people expect from MCT oil.
| MCT Type | Carbon Atoms | Primary Benefit | Absorption Speed |
|---|---|---|---|
| C8 (Caprylic) | 8 | Mental focus and rapid ketones | Fastest |
| C10 (Capric) | 10 | Gut health and immune support | Fast |
| C12 (Lauric) | 12 | Antimicrobial and general health | Slowest |
If your goal is athletic performance or staying in ketosis, you generally want a higher concentration of C8. If you want a well-rounded supplement that supports your gut and overall wellness, a blend of C8 and C10 is often the best choice. Most pure MCT oils will significantly limit or entirely remove C12 to ensure the product remains liquid at room temperature and delivers fast results.
The BUBS MCT Oil Powder is one convenient way to add a C8 and C10-focused MCT blend to your routine.
Bottom line: The shorter the chain, the faster the energy. C8 and C10 are the primary drivers of the benefits associated with MCT supplementation.
Why Quality and Sourcing Matter
Not all MCT oils are created equal. Many cheaper versions on the market are sourced from palm oil. The palm oil industry is a major contributor to rainforest destruction and habitat loss. Choosing a product that is 100% coconut-sourced is a better choice for the planet and often results in a cleaner final product.
The extraction process also matters. Some companies use harsh chemicals like hexane to separate the fats. A clean extraction process uses only heat, pressure, and water. This ensures that the oil you put in your body is free from chemical residues. We prioritize these clean methods because what you put in your body should be as pure as possible.
Third-party testing is another factor to consider. This ensures that the breakdown of C8 and C10 on the label actually matches what is in the bottle. For athletes, NSF for Sport certification is the gold standard. It guarantees the product is free from contaminants and banned substances. Our commitment to quality means we don't take shortcuts on testing or sourcing.

Key Takeaway: Always look for 100% coconut-sourced MCT oil that is third-party tested. Avoid palm-sourced oils to support environmental sustainability.
How to Incorporate MCTs Into Your Routine
The most common way to use MCT oil is by adding it to coffee. This is often called "bulletproof" coffee. When you blend MCT oil with coffee, the fats help slow the absorption of caffeine. This leads to a more stable, prolonged energy boost without the typical afternoon crash.
However, liquid oil can sometimes be messy or difficult to take on the go. This is where an MCT powder becomes useful. Our MCT Oil Creamer is designed to mix effortlessly into any hot or cold beverage. It provides the same C8 and C10 benefits but in a more convenient, creamy format. It’s a great option for travel or for those who want a better texture in their morning cup.
You can also use MCT oil in:
- Smoothies and protein shakes
- Salad dressings
- Nut butters
- Drizzled over roasted vegetables after cooking

Note: Because MCT oil has a low smoke point, it is not suitable for high-heat frying. Use it as a finishing oil or mix it into prepared foods to preserve its nutritional integrity.
Managing Your Dosage
If you are new to MCTs, it is important to start slowly. Because they are absorbed so quickly, taking too much at once can lead to digestive discomfort. Some people refer to this as "disaster pants." Your digestive system needs time to adjust to processing concentrated medium-chain fats.
Start with a small dose, such as one teaspoon or half a scoop of powder. Observe how your body reacts over a few days. If you feel fine, you can gradually increase the dose to a full tablespoon or a full scoop. Most people find that one to two servings a day is the sweet spot for sustained energy and mental clarity.
Taking MCTs on an empty stomach can provide the fastest ketone boost, but it is also the most likely to cause a localized stomach ache for beginners. If you have a sensitive stomach, try taking your MCTs with a small amount of food or mixing them into a protein shake.
Important: Always start with a low dose (5g or 1 tsp) and work your way up to a full serving over 7–10 days to avoid digestive upset.

FAQ
Is C8 better than C10?
It depends on your specific goal, but for most people seeking energy and ketone production, C8 is considered superior because it is absorbed faster. C10 is still a high-quality fat, but it is more valued for its antifungal and immune-supporting properties. Many high-performance oils use a blend of both to provide a broader range of benefits.
Can I get enough MCTs from just eating coconut oil?
While coconut oil is healthy, it is not a concentrated source of the fastest-acting MCTs. About 50% of coconut oil is C12, which behaves more like a long-chain fat and is slower to provide energy. To get the specific performance benefits of C8 and C10, a purified MCT oil or powder is a much more efficient choice.
Does MCT oil break a fast?
MCT oil contains calories, which technically breaks a physiological fast. However, because it does not trigger a significant insulin response and supports ketone production, many people use it during intermittent fasting. It can help manage hunger and provide mental energy without the metabolic downsides of eating a full meal.
How soon will I feel the effects of C8 and C10?
Most people report feeling increased mental clarity and stable energy within 15 to 30 minutes of consumption. Because these fats go straight to the liver for conversion into ketones, the metabolic response is much faster than traditional fats. Results can vary based on your individual metabolism and whether you take it on an empty stomach.
