Introduction

You are standing in your kitchen, looking at your supplement cabinet. In one hand, you have a bottle of MCT oil, ready for your morning coffee. In the other, a jar of fish oil capsules. You might wonder if taking these two fats at the same time is helpful or if they might interfere with each other. It is a common question for anyone looking to sharpen their mental edge or improve their physical recovery.

The short answer is yes. You can absolutely take MCT oil and fish oil together. In fact, combining them might be one of the smartest moves you can make for your daily routine. These two supplements serve different but complementary roles in your body. While one provides a fast-burning fuel source, the other works on long-term structural health.

At BUBS Naturals, we believe in keeping things simple and effective. Understanding how these fats interact helps you get the most out of your supplements without the guesswork. This guide will break down why this combination works, how it supports your goals, and the best way to add both to your day.

Quick Answer: Yes, you can take MCT oil and fish oil together. MCT oil acts as a rapid energy source, while fish oil provides essential omega-3 fatty acids for long-term health. Taking them together may actually improve the absorption of the fish oil.

Understanding the Two Fats

To understand why they work well together, we first need to look at what they are. Not all fats are created equal. They have different molecular lengths, which determines how your body digests and uses them.

What is MCT Oil?

MCT stands for medium-chain triglycerides. These are fats with a shorter chemical structure than the long-chain fats found in most foods like butter or olive oil. Because they are shorter, they are easier to digest.

When you consume MCT oil, it goes straight to your liver. Your body doesn't need bile or extra enzymes to break it down. Once in the liver, it is quickly turned into ketones. Ketones are a clean-burning fuel source for your brain and muscles. This is why many people use it for a quick energy boost without the "crash" associated with sugar.

What is Fish Oil?

Fish oil is a primary source of omega-3 fatty acids, specifically EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These are long-chain fatty acids. Unlike MCTs, fish oil is not used primarily for quick energy. Instead, it is used for "structural" purposes.

EPA and DHA are built into the membranes of your cells. They play a massive role in managing the body's natural inflammatory response and supporting heart and brain function. Because they are long-chain fats, they take longer to process than MCTs.

Feature	MCT Oil	Fish Oil (Omega-3)
Type of Fat	Medium-Chain Triglyceride	Long-Chain Polyunsaturated Fat
Primary Use	Fast energy and mental clarity	Heart, brain, and joint health
Metabolism	Bypasses normal fat digestion	Requires standard digestion
Source	Coconuts or palm kernel oil	Cold-water fish (anchovies, sardines)

The Benefits of Combining MCT and Fish Oil

Taking these two together is not just about convenience. There are biological reasons why this pair is effective for your wellness routine.

Improved Absorption

Fish oil is a fat-soluble nutrient. This means it needs to be consumed with other fats to be absorbed properly by your gut. If you take fish oil on an empty stomach, your body may not be able to "grab" and use all the EPA and DHA.

MCT oil acts as a carrier. By taking fish oil alongside MCTs, you provide a fatty environment that helps your digestive system transport the omega-3s into your bloodstream. This increases the "bioavailability" of the fish oil, which is a fancy way of saying your body gets more of the good stuff.

Immediate Energy Meets Long-Term Support

Think of MCT oil as the fuel you put in your gas tank for a long road trip. It gives you the immediate power to get moving. Fish oil is more like the oil in your engine. It keeps the parts moving smoothly and prevents wear and tear over time.

By taking them together, you are addressing two needs at once. You get the mental clarity and physical energy from the MCT-driven ketones, and you provide the structural building blocks your cells need to stay healthy for the long haul.

Supporting a Healthy Inflammatory Response

Both MCT and fish oil may help manage inflammation, though they do it differently. MCTs can help provide a cleaner energy source that creates fewer metabolic "byproducts." Fish oil directly influences the signaling molecules that manage the body's inflammatory response.

Some studies on animals have suggested that adding MCTs to a fish oil regimen can help mitigate the body's response to inflammatory challenges. This makes the combination a favorite for athletes and veterans who push their bodies to the limit and need every bit of recovery help they can get.

Key Takeaway: Combining MCT and fish oil creates a "dual-threat" supplement routine. The MCT provides immediate energy and helps the body absorb the long-chain omega-3s in fish oil more efficiently.

How Your Body Processes These Fats

To really see the value of this pair, we have to look at the "portal vein" and the "lymphatic system." These are the two main pathways your body uses to move nutrients.

When you eat standard fats (long-chain), they are broken down and packaged into little bubbles called chylomicrons. These bubbles travel through your lymphatic system before entering your blood. It is a slow, steady process. Fish oil follows this path.

MCTs are different. They are small enough to enter the portal vein. This is a direct "highway" from your gut to your liver. This is why MCTs don't get stored as body fat as easily as other oils. They are treated as an immediate priority for energy.

By having both pathways active at the same time, you are essentially feeding your body on two different levels. You are providing "fast" fat for the liver and "slow" fat for the rest of your cells.

Myth: Taking MCT oil will make you store the fish oil as body fat. Fact: MCT oil is actually less likely to be stored as fat than other oils because it is metabolized so quickly. It doesn't "push" other fats into storage; it simply provides a medium for them to be absorbed.

Practical Ways to Combine Them

You don't need a complicated plan to make this work. Most people find that the easiest way to combine these is by timing them with a meal or a morning beverage.

The Morning Power Routine

Many people start their day with coffee. This is a perfect time for MCTs. Our MCT Oil Creamer is designed to mix instantly into hot coffee, giving it a rich, creamy texture without any dairy or fillers.

While you sip your MCT-boosted coffee, you can take your fish oil capsules. The MCT in your coffee will help your body process the omega-3s in the capsules. This also helps prevent the "fishy burps" that some people experience when taking fish oil on a completely empty stomach.

Smoothies and Shakes

If you prefer a cold start to your day, both oils work great in a smoothie. You can add a scoop of our Collagen Peptides for joint support, a tablespoon of liquid MCT oil, and your fish oil. The mechanical blending of a smoothie helps emulsify the fats, making them even easier for your stomach to handle.

Salad Dressings

If you prefer to take your supplements with food, you can create a high-performance salad dressing. Mix MCT oil with a bit of lemon juice, herbs, and your favorite vinegar. If you use a liquid fish oil instead of capsules, you can even mix a small amount of it into the dressing. Just be aware that fish oil has a strong flavor, so most people stick to capsules for convenience.

Dosage and Timing: How Much Is Too Much?

When starting with any fat-based supplement, the golden rule is: start low and go slow.

Starting with MCT Oil

MCT oil is very efficient, but your gut needs time to adjust to it. If you take too much at once, you might experience "disaster pants"—that sudden, urgent need for a bathroom.

Start: 1 teaspoon per day.
Middle: Move to 1 tablespoon after a week of no issues.
Goal: Most people settle at 1–2 tablespoons daily.

Starting with Fish Oil

Fish oil dosage is usually measured by the total amount of EPA and DHA, not just the "total fish oil" on the label.

Standard dose: Look for a combined 1,000mg to 2,000mg of EPA and DHA per day.
Check the label: Ensure the oil is third-party tested for purity. You want to make sure you aren't consuming heavy metals like mercury or lead.

Taking Them Together

There is no "perfect" ratio of MCT to fish oil. Most people take their standard dose of fish oil (usually 1–3 capsules) with their standard dose of MCT (1 tablespoon).

Note: If you have a sensitive stomach, try taking this combination with a small amount of protein or fiber. This slows down digestion just enough to keep things moving comfortably.

Why Quality Matters for Both

The supplement world is full of cheap fillers and low-quality ingredients. When you are putting fats into your body, quality is everything. Rancid fat is worse than no fat at all.

Choosing Your MCT

Look for MCT oil that is sourced from 100% coconuts. Some brands use palm oil, which is often harvested in ways that are hard on the environment. You also want an oil that is high in C8 (caprylic acid) and C10 (capric acid). These are the specific lengths that provide the fastest energy.

Our products are built on the legacy of Glen "BUB" Doherty, a Navy SEAL who valued excellence. That is why our MCT products are clean, simple, and science-backed. We don't use fillers or "non-dairy creamers" that are actually full of corn syrup.

Choosing Your Fish Oil

Fish oil is prone to oxidation. If it smells extremely fishy or like it has gone "off," it probably has. Look for:

Source: Wild-caught, sustainable fish.
Form: Triglyceride form is usually better absorbed than ethyl ester form.
Purity: Look for labels that mention molecular distillation to remove contaminants.

Bottom line: Taking high-quality fats together is a great strategy, but taking low-quality, rancid fats together will only cause inflammation. Invest in products that are third-party tested.

Who Should (and Shouldn't) Take This Combination?

Most active adults can benefit from this duo, but there are a few specific groups who might find it especially helpful.

The Keto Community

If you are on a ketogenic diet, you are already prioritizing fats. MCT oil is a staple because it helps your body produce ketones faster, which can make the transition into ketosis easier. Adding fish oil ensures that while you are burning fat for fuel, you are also getting the essential fatty acids that your body cannot make on its own.

Athletes and High Performers

If you train hard, you are constantly asking your body to repair itself. The "carrier" effect of MCT oil helps ensure your recovery-focused omega-3s are getting where they need to go. Many athletes report that this combination helps them feel less "stiff" the morning after a heavy session.

The Aging Brain

As we get older, our brains sometimes become less efficient at using glucose (sugar) for energy. Ketones from MCT oil provide an alternative fuel source. When you pair that with DHA (the primary fat in the brain), you are giving your cognitive health a solid foundation.

A Note on Medical Conditions

While these are natural fats, they can interact with certain medications.

Blood Thinners: Fish oil has a mild blood-thinning effect. If you are on medication for blood pressure or heart issues, talk to your doctor.
Fat Malabsorption: If you have issues with your gallbladder or pancreas, your body might struggle with high doses of fat.
Surgery: Most doctors recommend stopping fish oil a week before surgery to ensure normal blood clotting.

Integrating Into a Broader Wellness Plan

Taking MCT and fish oil is a great step, but it works best when it is part of a complete lifestyle. Supplementation is the "extra 10%" that helps you perform your best.

We recommend pairing your healthy fats with a hydration strategy. Since MCTs can sometimes lead to increased water loss as your body shifts into fat-burning mode, staying on top of your electrolytes is key. Our Hydrate or Die electrolyte mix is designed for this exact scenario—high performance with no added sugar.

You can also layer in collagen. While fats support the "fluid" parts of your cells, collagen supports the "structural" parts like your tendons, ligaments, and skin. A morning routine of MCT oil in coffee, a scoop of Collagen Peptides, and a fish oil capsule covers almost every base of physical and mental readiness.

Key Takeaway: Wellness is about synergy. Fats provide the fuel and the cell structure, collagen provides the framework, and electrolytes provide the electrical balance.

Common Misconceptions About Taking Fats

There is still a lot of old information floating around about dietary fat. Let's clear up a few things so you can feel confident in your routine.

"Will this much fat make me gain weight?"

Fat has nine calories per gram, which is more than protein or carbs. However, MCT oil is metabolized differently. Because it is burned for energy so quickly, it is much less likely to be stored as adipose tissue (body fat). Furthermore, fats are highly satiating. Taking them in the morning often helps people eat less throughout the rest of the day.

"Do I need to take them at different times?"

There is no evidence that you need to separate them. In fact, as we've discussed, taking them together is likely better for the fish oil's absorption. Your digestive system is more than capable of handling different types of fats simultaneously.

"Can I just use coconut oil instead of MCT?"

Coconut oil contains MCTs, but it also contains a lot of long-chain fats. Pure MCT oil is a concentrated version. It is like the difference between eating a whole orange and taking a Vitamin C supplement. Both are good, but one is a targeted tool for a specific job.

The BUBS Way: Purpose-Driven Wellness

FAQ

Can I mix MCT oil and liquid fish oil in the same spoon?

Yes, you can mix them directly if you prefer liquid supplements. However, fish oil has a very strong taste that many find unpleasant. Most people find it easier to use MCT oil in their coffee or food and take their fish oil in capsule form to avoid the flavor.

Will taking these together cause an upset stomach?

It can if you take too much too fast. MCT oil is known for causing digestive urgency in high doses, and fish oil can sometimes cause mild nausea if taken on a completely empty stomach. To avoid this, start with a small amount of MCT and take both with a small snack or a full glass of water.

Is this combination better for people on a keto diet?

It is particularly beneficial for those on keto. MCT oil helps your body produce the ketones needed for the diet, while fish oil provides the essential long-chain fats that are sometimes missing from a diet heavy in saturated fats. Together, they provide a balanced fat profile.

Can I cook with both MCT oil and fish oil?

No, we do not recommend cooking with either. MCT oil has a very low smoke point and can break down or even catch fire at high temperatures. Fish oil is very delicate and will oxidize (go rancid) if heated. Both are best used raw, stirred into coffee, or added to foods after they have been cooked.
