Introduction

If you have spent any time in the wellness or fitness space lately, you have likely heard about MCTs. They are the fatty acids that fueled the rise of keto coffee and remain a staple for athletes looking for a clean energy source. While many people associate these fats exclusively with coconut oil, the reality of which oils are MCT is a bit more nuanced. Not all fats are created equal, and understanding the specific sources of medium-chain triglycerides can help you better fuel your body for your next adventure.

At BUBS Naturals, we focus on providing clean, functional nutrition that actually works for an active lifestyle. Whether you are prepping for a morning rucking session or just trying to stay sharp during a long workday, the type of fat you consume matters. MCTs are processed differently by your body than the standard fats found in most western diets, making them an efficient fuel source for the brain and muscles.

This guide will break down the natural sources of MCTs, the chemical differences between various chain lengths, and the specific ways these oils can support your recovery and performance. We will also clarify the common confusion between whole food sources like coconut oil and concentrated supplements like MCT Oil Creamer.

Quick Answer: The primary natural sources of MCTs are coconut oil and palm kernel oil, with smaller amounts found in dairy products like butter and whole milk. Concentrated MCT oil is typically a supplement made by extracting specific medium-chain fatty acids—usually C8 (caprylic acid) and C10 (capric acid)—to provide a faster, more efficient energy source.

What Are Medium-Chain Triglycerides?

To understand which oils are MCT, we have to look at the chemistry of fat. Triglycerides are the technical name for fat molecules. They consist of a glycerol "backbone" and three fatty acid "tails." These tails are made of carbon atoms, and the length of these tails determines how your body digests and uses that fat.

Most fats in the modern diet are long-chain triglycerides (LCTs). These have 13 to 21 carbon atoms. LCTs take a long time to break down. They require bile and pancreatic enzymes for digestion, and they are often stored as body fat for later use.

Medium-chain triglycerides (MCTs) have shorter tails, ranging from 6 to 12 carbon atoms. Because they are shorter, they are much easier for your body to process. Instead of moving through the entire digestive system like LCTs, MCTs go straight from the gut to the liver. This allows for a quick conversion into energy, often in the form of ketones.

The Four Types of MCTs

There are four specific fatty acids that fall under the MCT umbrella. Each has its own properties and benefits based on the number of carbon atoms in its chain:

C6 (Caproic Acid): This is the shortest chain. It converts to energy very quickly, but it is rarely found in commercial supplements because it has a notoriously unpleasant taste and smell.
C8 (Caprylic Acid): Many consider this the gold standard for energy. It has eight carbon atoms and is the most efficient at raising blood ketone levels. It is the primary ingredient in high-quality MCT oils.
C10 (Capric Acid): With ten carbon atoms, this chain takes slightly longer to process than C8 but still provides a rapid energy boost. It also possesses noted antifungal and immune-supporting properties.
C12 (Lauric Acid): This is the longest "medium" chain. Because it has 12 carbons, it behaves somewhat like a long-chain fat during digestion, moving more slowly through the body. However, it is prized for its powerful antimicrobial and antibacterial effects.

Natural Sources: Which Oils Contain MCTs?

While you can find MCTs in supplement form, they occur naturally in several whole foods. If you are looking to increase your intake through your diet, these are the primary oils and fats to consider.

Coconut Oil

Coconut oil is the most famous natural source of MCTs. About 55% to 65% of the fatty acids in coconut oil are medium-chain triglycerides. However, it is important to note that the vast majority of the MCTs in coconut oil is C12 (lauric acid).

While lauric acid is beneficial, it does not provide the same immediate "hit" of energy that people expect from a concentrated MCT supplement. If your goal is sustained, slow-burning energy and immune support, coconut oil is an excellent choice. If you want a quick metabolic spark, you might need something more concentrated.

Palm Kernel Oil

Palm kernel oil is another rich source of MCTs, containing about 50% medium-chain fats. It is often used in the industrial production of MCT oil because it is cost-effective and high in C8 and C10.

At BUBS Naturals, we prioritize sustainability and ethics. While palm kernel oil is high in MCTs, the palm industry is often associated with environmental concerns. This is why many high-quality brands, including us, focus on coconut-derived MCTs to ensure the product is as clean for the planet as it is for your body.

Dairy Products

Many people are surprised to learn that dairy contains MCTs. While the percentages are much lower than in tropical oils, they are still present.

Butter: Contains about 8% MCTs.
Whole Milk: Contains about 9% MCTs.
Goat Cheese: Often cited as having a higher concentration of the "capra" fatty acids (C6, C8, and C10) than cow's milk.

Dairy sources tend to have a higher ratio of C8 and C10 compared to C12. This is one reason why adding butter or ghee to coffee became such a popular trend—it provides a small but natural dose of those fast-acting MCTs.

Food Source	Total MCT Content	Primary MCT Type
Coconut Oil	~60%	Lauric Acid (C12)
Palm Kernel Oil	~50%	Lauric Acid (C12)
Whole Milk	~9%	Capric Acid (C10)
Butter	~8%	Caprylic Acid (C8)
Goat Milk/Cheese	~10-15%	C6, C8, C10

MCT Oil vs. Coconut Oil: What Is the Difference?

A common question we hear is whether you can just use coconut oil instead of MCT oil. The answer depends on your specific goals.

Coconut oil is a whole food. It contains LCTs, various MCTs (mostly C12), and has a distinct flavor and scent. It is solid at room temperature and is excellent for high-heat cooking because it has a relatively high smoke point.

MCT oil is a supplement created through a process called fractionation. This involves heating the oil (usually coconut or palm) to separate the different fatty acids based on their melting points. The C8 and C10 are pulled out and concentrated into a liquid oil that remains liquid even in the fridge.

Key Takeaway: MCT oil is a "purified" version of the fats found in coconut oil. By removing the slower-digesting C12 and the long-chain fats, you get a product that is designed for rapid energy and mental clarity rather than general cooking.

Why Choose Concentrated MCT Oil?

The main reason to choose a concentrated oil over a whole food source is efficiency. Because MCT oil is 100% medium-chain fats, your liver can process it into ketones almost immediately. This makes it a popular tool for:

Supporting a ketogenic diet or low-carb lifestyle.
Providing a pre-workout energy boost without a sugar crash.
Enhancing mental focus during demanding tasks.
Managing hunger and cravings during fasts.

Our MCT Oil Creamer is designed to be an easy-mixing powder that provides these benefits without the mess of a liquid oil. We use a clean, coconut-sourced foundation because we believe the source of your fat matters as much as the amount.

How MCTs Function in the Body

The magic of MCTs lies in their metabolic pathway. When you eat most fats, they go through a complex process of being broken down by bile in your small intestine. They then enter the lymphatic system and eventually the bloodstream. It is a slow process.

MCTs are different. They are water-soluble enough to enter the portal vein, which leads directly to your liver. Once in the liver, they have a "VIP pass." They do not require carnitine to enter the mitochondria (the powerhouses of your cells). This means they can be burned for fuel right away.

Ketone Production

One of the most significant roles of MCTs is their ability to stimulate the production of ketones. Ketones are an alternative fuel source for the brain. Normally, the brain runs on glucose (sugar). However, during times of fasting or low-carb intake, the brain can use ketones quite efficiently.

Many athletes and professionals report that this shift to ketone fuel leads to "leveling out" their energy. Instead of the peaks and valleys of blood sugar, they experience a steady, calm focus. This is why MCT oil has become so popular in the morning—it helps bridge the gap between your last meal and your next one without a drop in performance.

Myth: MCT oil is a "weight loss miracle" that burns fat while you sit on the couch. Fact: MCT oil may support weight management by increasing satiety (fullness) and providing an efficient energy source that is less likely to be stored as fat, but it still contains calories. It is a tool for an active lifestyle, not a replacement for a solid diet and training plan.

Practical Ways to Use Different MCT Sources

Knowing which oils are MCT is only half the battle. You also need to know how to use them without causing digestive upset. Because MCTs are processed so quickly, taking too much too soon can lead to what some call "disaster pants"—or more politely, urgent digestive distress.

In the Kitchen with Coconut Oil

If you are cooking at high heat, stick to coconut oil or ghee. Coconut oil is great for:

Sautéing vegetables.
Replacing butter in vegan baking.
Greasing pans for roasting.

The presence of C12 (lauric acid) makes it very stable. It won't oxidize as easily as some vegetable oils, making it a "cleaner" choice for the stove.

Supplementing with MCT Oil

If you are using a concentrated liquid oil or powder, keep it "raw." MCT oil has a low smoke point, meaning it will burn and lose its beneficial properties if you try to fry an egg in it. Instead, use it as an additive:

Coffee and Tea: This is the most common use. It creates a creamy texture when blended.
Smoothies: Add a scoop of MCT powder to your post-workout shake for better recovery energy.
Salad Dressings: Mix liquid MCT oil with apple cider vinegar and herbs for a quick, keto-friendly dressing.
Drizzled Over Food: You can add it to oatmeal, yogurt, or even over a steak after it has finished cooking.

Dosage and Safety Considerations

When starting with MCT oil, the golden rule is to start small. Your gut needs time to adapt to the rapid influx of medium-chain fats.

Most people find success starting with just one teaspoon or half a scoop of powder per day. Monitor how you feel for a few days. If your digestion is fine, you can gradually move up to one or two tablespoons (or full scoops) spread throughout the day.

While MCTs are generally safe for most people, there are a few things to keep in mind:

Caloric Density: MCTs are pure fat. One tablespoon has about 100 to 130 calories. If you are adding them to your diet without adjusting other calories, you may see weight gain.
Cholesterol: Some people find that high intakes of saturated fats, even MCTs, can impact their lipid panels. If you have concerns about heart health, it is always a good idea to consult with your healthcare provider.
Liver Health: While the liver processes MCTs efficiently, very high doses over long periods should be approached with caution, especially if you have pre-existing liver conditions.

The Role of MCTs in Athletic Performance

For the BUBS Naturals community, performance is usually the top priority. We want to know how our nutrition helps us move faster, lift heavier, and recover better. MCTs offer a unique advantage here because they are "glycogen sparing."

When you exercise at high intensity, your body primarily burns glycogen (stored sugar). Once that glycogen is gone, you "bonk" or hit the wall. By providing a source of ketones through MCTs, you give your body an alternative fuel source to tap into before it burns through all its sugar stores. This may support better endurance during long runs, rucks, or cycling sessions.

Furthermore, the antimicrobial properties of C10 and C12 may support a healthy gut microbiome. Since a huge portion of your immune system lives in your gut, keeping it balanced is essential for staying consistent with your training.

If you are building a broader performance stack, Creatine Monohydrate is another clean option many athletes reach for.

Bottom line: MCTs are a unique class of fats that provide rapid energy by bypassing traditional digestive routes, making them a powerful tool for mental clarity and physical endurance when used correctly.

Choosing the Right MCT Product

If you decide to move beyond whole foods and try a supplement, you will see a lot of options on the shelf. Here is what to look for to ensure you are getting a clean, effective product:

Source: Look for "100% Coconut Sourced." Some cheaper brands blend in palm oil without disclosing how it was harvested.
C8/C10 Ratio: A high-quality oil should be almost entirely C8 and C10. If the label doesn't specify the breakdown, it might be heavy on the slower-digesting C12.
No Fillers: This is especially important for MCT powders. Many brands use maltodextrin (a sugar) or corn starch as a carrier. We use a clean acacia fiber, which acts as a prebiotic for gut health.
Testing: Ensure the product is third-party tested. For athletes, NSF for Sport certification is the gold standard for purity and safety.

At BUBS Naturals, we pride ourselves on meeting these standards. You can explore our full MCT collection to see the difference. Our MCT products are designed to mix effortlessly into your lifestyle, whether you're at a trailhead or in an office. We don't believe in adding "BS" to our labels—just simple, science-backed ingredients that help you feel the difference.

FAQ

Is coconut oil the same as MCT oil?

No, they are different products. Coconut oil is a whole food containing a mix of different fats, including a high percentage of lauric acid (C12), while MCT oil is a concentrated supplement that usually contains only the fastest-acting medium-chain fats, C8 and C10.

Which oil has the most MCTs?

Coconut oil and palm kernel oil have the highest natural concentration of MCTs, both hovering around 50% to 60%. However, a purified MCT oil supplement is 100% medium-chain triglycerides, providing a much more potent dose per serving.

Can I use MCT oil for cooking?

It is not recommended for high-heat cooking because it has a low smoke point and can break down or catch fire at relatively low temperatures. It is best used "raw" as an addition to coffee, smoothies, salad dressings, or drizzled over finished meals.

Are there MCTs in olive oil?

No, olive oil is primarily composed of long-chain triglycerides, specifically oleic acid, which is a monounsaturated fat. While olive oil is incredibly healthy and a staple of the Mediterranean diet, it does not provide the rapid-energy benefits associated with medium-chain triglycerides.
