Introduction
Adding a splash of MCT Oil Creamer to your morning coffee or pre-workout shake has become a staple for many in the wellness community. These medium-chain triglycerides are prized for their ability to provide quick energy and support ketone production. At BUBS Naturals, we believe in providing clean, functional supplements that fuel your next adventure, whether that is a mountain hike or a busy day at the office.
However, just because a supplement is popular doesn't mean it is a universal fit for every body. While most people tolerate these fats well, there are specific groups who should proceed with caution or avoid them entirely. This guide will help you understand the science behind how these fats interact with your system and identify if you should steer clear. We will cover the specific medical conditions, lifestyle factors, and digestive sensitivities that may make this supplement a poor choice for your routine.
Understanding the MCT Mechanism
To understand why some people should avoid MCT oil, you first need to understand how it works in the body. Most fats you eat are long-chain triglycerides (LCTs). These require a complex digestion process involving bile and pancreatic enzymes. They travel through your lymphatic system before entering the bloodstream.
Medium-chain triglycerides are different because their carbon chains are shorter. This smaller size allows them to bypass the standard digestion route. Instead, they go straight to your liver via the portal vein. Your liver converts them into ketones, which are used for immediate energy. This rapid-fire absorption is exactly why athletes love it, but it is also the primary reason it can cause issues for certain people.
Quick Answer: Individuals with severe liver disease, uncontrolled diabetes, or heart disease should generally avoid MCT oil. Those with sensitive digestive systems or specific allergies to coconut or palm should also exercise caution or consult a healthcare provider before use.
Creamers
People with Severe Liver Disease
The liver is the primary processing plant for MCTs. Because these fats are sent directly to the liver for conversion, they can place a significant workload on an organ that is already struggling. If you have a history of severe liver issues, this supplement may not be for you.
Cirrhosis and Advanced Liver Damage
For those with cirrhosis or significant liver scarring, the organ cannot process fats efficiently. Research suggests that high doses of medium-chain fats might lead to an accumulation of fat within the liver cells. This can exacerbate existing conditions or lead to complications in those with compromised hepatic function.
Portal Hypertension and Shunts
Individuals with high blood pressure in the liver (portal hypertension) or those who have had a portacaval shunt placed must be extremely careful. A portacaval shunt is a surgical connection that redirects blood flow. Because MCTs rely on the portal vein for transport, altering this pathway changes how the body handles the supplement. In these cases, taking the oil could lead to metabolic imbalances that are difficult to manage.
Important: If you have been diagnosed with any form of liver disease, it is vital to consult your doctor before adding supplemental fats to your diet. The direct-to-liver nature of MCTs makes them a unique metabolic case.
Individuals with Uncontrolled Diabetes
MCT oil is a favorite in the keto community because it helps the body produce ketones. For most, this is a benefit. However, for people with uncontrolled diabetes—particularly Type 1—this can be a double-edged sword.
Ketones are an alternative fuel source, but when they build up to excessive levels in the blood of a diabetic person, it can lead to a dangerous state called ketoacidosis. While nutritional ketosis from a supplement is different from diabetic ketoacidosis (DKA), adding supplemental ketones to a system that cannot properly regulate blood sugar and insulin is risky.
Some studies suggest that MCTs can improve insulin sensitivity in Type 2 diabetics. However, the risk of shifting blood chemistry too quickly remains. If your blood sugar levels are not stable, adding a potent fat source that alters ketone levels should only be done under strict medical supervision.

Join The ClubCardiovascular Health Concerns
MCT oil is a concentrated source of saturated fat. While the conversation around saturated fat has evolved, it remains a point of concern for those with existing heart disease or specific genetic predispositions to high cholesterol.
The Hyper-Responder Phenomenon
Most people can consume moderate amounts of saturated fats without a significant spike in LDL (the "bad") cholesterol. However, a segment of the population are "hyper-responders." For these individuals, adding concentrated saturated fats like MCT oil can cause a sharp rise in cholesterol markers.
Existing Heart Disease
If you are currently managing heart disease or have had a cardiovascular event, your dietary fat intake is likely closely monitored. While some research indicates that MCTs may help raise HDL (the "good") cholesterol, the high-calorie and saturated fat content means they must be used sparingly.
Myth: MCT oil is a "heart-healthy" fat that everyone should take to lower cholesterol. Fact: While it may support some lipid markers, it is a concentrated saturated fat. Its impact on cholesterol varies significantly based on genetics and overall diet.
Digestive Sensitivities and GI Distress
One of the most common reasons people stop using MCT oil has nothing to do with long-term health and everything to do with immediate comfort. Because these fats are absorbed so quickly, they can "shock" the digestive tract.
The "MCT Disaster"
You may have heard the term "disaster pants" in fitness circles. This refers to the sudden, urgent diarrhea that can occur when someone takes too much MCT oil too fast. The oil has an osmotic effect, drawing water into the bowels. This can lead to:
- Severe abdominal cramping
- Bloating and gas
- Nausea and vomiting
- Urgent loose stools
Managing the Transition
At BUBS Naturals, we often recommend that people who are sensitive to liquid oils try a powdered version instead. Our MCT Oil Creamer is designed to be gentler on the stomach. The powder form is often encapsulated with a carrier that slows down the absorption just enough to prevent the common GI issues associated with pure liquid oil.
Key Takeaway: If you have a history of IBS, Crohn’s disease, or general digestive sensitivity, liquid MCT oil might be too aggressive. Start with a tiny dose or opt for a powdered version to test your tolerance.
Those with Coconut or Palm Allergies
Most high-quality MCT oils are derived from coconut oil or palm kernel oil. While the fractionation process removes many of the proteins that typically trigger allergies, the risk is not zero.
If you have a severe allergy to coconuts, you should be very careful. Even if the product claims to be pure, cross-contamination or trace proteins can cause a reaction. Symptoms of an allergic reaction can include hives, itching, swelling of the face or throat, and difficulty breathing. Always check the source of the MCTs. If you are allergic to coconut, look for a 100% palm-derived oil, though these are less common and often have their own environmental concerns.
Pregnancy and Breastfeeding
There is currently a lack of long-term clinical data regarding the use of concentrated MCT supplements during pregnancy or while breastfeeding. While MCTs are naturally present in breast milk, taking them in a highly concentrated supplement form is a different matter.
During pregnancy, your body undergoes massive metabolic shifts. Introducing supplements that significantly alter ketone production or fat metabolism should be approached with caution. Most practitioners recommend sticking to whole-food sources of healthy fats during this time unless a supplement is specifically prescribed to address a nutrient deficiency.
People Taking Specific Medications
MCT oil can interact with how your body absorbs or processes certain drugs. If you are on a strict medication protocol, check for potential interactions.
Weight Loss Medications
Drugs like Orlistat (Alli) work by blocking the absorption of fats in the intestines. Because MCT oil is a fat, taking it while on these medications can lead to increased side effects, such as oily spotting or severe GI distress. The medication is trying to stop fat absorption while you are intentionally adding a concentrated dose of it.
Seizure Medications
Historically, ketogenic diets have been used to manage epilepsy. However, if you are taking medications for seizures, such as valproic acid, adding MCT oil can change the concentration of the drug in your system. This can interfere with the medication’s effectiveness or increase the risk of side effects.
How to Determine if MCT Oil is Right for You
If you don't fall into the high-risk categories mentioned above, you may still want to test your tolerance before making it a daily habit. We recommend a "start low, go slow" approach.
The Testing Protocol
- Start with a teaspoon: Do not start with the standard tablespoon dose. A single teaspoon is enough to see how your stomach reacts.
- Take it with food: Taking MCT oil on an empty stomach is the fastest way to trigger a bathroom emergency. Mix it into a smoothie or a bowl of oatmeal.
- Monitor your energy: Notice if you feel a steady rise in energy or if you feel jittery and nauseous.
- Check your labs: If you decide to use it long-term, have your cholesterol and liver enzymes checked during your annual physical to ensure your body is responding well.
Choosing a Quality Product
Not all MCT oils are created equal. Some are diluted with cheap fillers or contain a high percentage of Lauric acid (C12), which behaves more like a long-chain fat and doesn't offer the same quick energy benefits as Caprylic acid (C8) or Capric acid (C10).
Our MCT Oil Creamer is a single-ingredient, coconut-sourced powder that is third-party tested. We focus on C8 and C10 because they are the most efficient for energy production. Using a clean, tested product reduces the risk of consuming impurities that could cause additional side effects.
Bottom line: Most people can safely enjoy the benefits of MCTs by starting with small doses and choosing high-quality, powdered versions that are easier on the digestive system.
Alternatives to MCT Oil
If you find that you fall into one of the categories of people who should avoid MCT oil, you aren't out of luck. There are plenty of other ways to support your energy and metabolic health without the risks.
- Coconut Oil: While it contains MCTs, it is much less concentrated. It is absorbed more slowly, which can be easier on the liver and the gut.
- Ghee or Butter: These provide stable, long-burning energy and are common in many traditional diets.
- Omega-3 Fatty Acids: For heart and brain health, focusing on fish oil or algae-based DHA/EPA is often a better choice for those with cardiovascular concerns.
- BUBS Naturals Collagen Peptides: If you are looking for a supplement to support recovery and joint health without the fat content, collagen is a versatile, protein-based alternative that mixes easily into any drink.

FAQ
Can I take MCT oil if I have a fatty liver?
It is generally advised to be very cautious with MCT oil if you have non-alcoholic fatty liver disease (NAFLD). Because MCTs are processed directly by the liver, high doses could potentially increase fat accumulation in liver cells. Always consult your healthcare provider to see if a small dose is appropriate for your specific stage of liver health.
Why does MCT oil give me a stomach ache?
MCT oil is absorbed very rapidly, which can cause an osmotic effect in your gut, drawing in water and causing cramping or diarrhea. This is especially common when taking the oil on an empty stomach or starting with a high dose. Switching to a powdered MCT or taking it with a meal can often resolve this issue.
Is MCT oil safe for people with high cholesterol?
It depends on whether you are a "hyper-responder" to saturated fats. While some people see no change or even an improvement in their lipid profile, others may see a significant rise in LDL cholesterol. If you have high cholesterol, it is best to monitor your levels closely when starting any saturated fat supplement.
Can MCT oil cause ketoacidosis?
For a healthy person, MCT oil helps produce nutritional ketosis, which is safe. However, for those with Type 1 diabetes, there is a risk that supplemental ketones could contribute to diabetic ketoacidosis (DKA) if insulin is not managed correctly. People with uncontrolled diabetes should avoid using MCT oil without direct medical supervision.
