In today's health and wellness landscape, many individuals are seeking effective strategies to manage their weight, boost their energy levels, and enhance cognitive function. Among the numerous supplements available, MCT (medium-chain triglyceride) oil has emerged as a popular choice, celebrated for its potential to support weight loss, provide quick energy, and improve mental clarity. This article explores the science behind MCT oil, its benefits, and how to incorporate it into your daily routine for optimal weight loss results.
Understanding MCT Oil
Medium-chain triglycerides (MCTs) are fats containing fatty acid chains of medium length, typically ranging from 6 to 12 carbon atoms. Unlike long-chain triglycerides (LCTs), which are commonly found in most dietary fats, MCTs are rapidly absorbed by the body and transported directly to the liver. In the liver, MCTs can be converted into ketones, an alternative energy source for the body.
MCT oil is primarily derived from coconut oil and palm kernel oil, with coconut oil being the preferred source due to environmental concerns associated with palm kernel oil production. The process of extracting MCT oil from these sources involves fractionation, which separates and concentrates the MCTs from the original oil.
Potential Benefits of MCT Oil
MCT oil has gained recognition for its potential health benefits, including:
- Enhanced Feelings of Fullness: Research suggests that MCT oil can promote feelings of fullness, which may lead to a decrease in overall caloric intake.
- Increased Fat Burning: MCT oil may increase the rate at which your body burns fat for fuel.
- Quick Energy Source: Starting your day with MCT oil can provide a quick and sustained source of energy.
- Cognitive Support: MCT oil can enhance mental clarity and cognitive function.
- Appetite Control: Using MCT oil as a midday supplement can help control hunger and prevent overeating.
MCT Oil and Weight Loss
MCT oil may offer several potential mechanisms for supporting weight loss:

- Reduced Calorie Intake: By promoting feelings of fullness, MCT oil may help reduce overall calorie consumption.
- Increased Energy Expenditure: MCT oil may increase the rate at which your body burns calories, contributing to weight loss.
- Ketone Production: MCTs can be converted into ketones, which may help promote fat burning and weight loss, especially when following a ketogenic diet.
A 2015 review of 13 randomized controlled trials indicated that MCTs could support modest weight loss, fat loss, and reduced body size. However, the authors noted that many of the studies were of questionable quality, and industry funding may have influenced the results. Another 2015 review of 11 trials drew similar conclusions regarding study quality.
Incorporating MCT Oil into Your Routine
To maximize the potential benefits of MCT oil for weight loss, consider these strategies:
- Morning Boost: Add MCT oil to your morning coffee or smoothie to enhance mental clarity and reduce the urge to snack before lunch.
- Pre-Exercise Energy: Take MCT oil before exercise to boost your energy and endurance without the crash associated with sugar or caffeine.
- Midday Hunger Control: Use MCT oil as a midday supplement to help control hunger and prevent overeating.
- Recipe Experimentation: Incorporate MCT oil into your cooking or baking to add healthy fats and potential weight loss benefits to your meals.
While MCT oil can be beneficial at any time, it’s best to avoid taking it right before bed.
MCT Wellness: A Closer Look
MCT Wellness is a flavored powder combining C8 MCT oil (caprylic acid), grape/currant polyphenols, and acacia fiber. It is designed to boost ketones, energy, and gut health. The C8 MCT in MCT Wellness produces more ketones faster than C10/C12 MCTs, especially in lower-carb windows. Grape and currant polyphenols are being studied for antioxidant and cognitive support. All flavors are sugar-free, lectin-free, dairy-free, vegan, and third-party tested.
However, MCT Wellness has some limitations:

- Proprietary blends obscure exact MCT amounts.
- The finished MCT Wellness formula has not been tested in a peer-reviewed clinical trial as of this update.
- It is more expensive than plain C8 oils, which deliver 3-4× more MCT per dollar and transparent dosing.
- Many users report clumping issues with MCT Wellness.
MCT Oil vs. Coconut Oil
While MCT oil is derived from coconut oil, it has a higher concentration of MCTs compared to coconut oil. This means that your body breaks down coconut oil differently, absorbing it more slowly and storing it as fat.
MCT Oil Dosage
The amount of MCT oil you should take depends on how well you tolerate it and what benefit you’re trying to get. The most you should have in a day is around four to seven tablespoons, spread out throughout the day. Start with one teaspoon and work your way up to one or two tablespoons.
Potential Side Effects and Considerations
While MCT oil is generally safe for most people, it’s important to be aware of potential side effects and considerations:
- Digestive Discomfort: Some individuals may experience digestive discomfort, such as stomach pain, gas, cramps, bloating, diarrhea, or vomiting, especially when first starting.
- Calorie Content: MCT oil is high in calories, which can cause weight gain if not factored into your overall calorie intake.
- Saturated Fat: Large amounts of saturated fat may raise your cholesterol levels.
- Hunger Hormones: MCTs may stimulate the release of hunger hormones, potentially leading to overeating.
- Liver Fat Buildup: High doses could lead to fat buildup in the liver.
- Allergic Reactions: Rare/serious allergic reactions (coconut allergy) can occur.
It’s essential to talk to a dietitian to find a dose that’s right for you. And since MCT oil doesn’t have essential fatty acids, you should include other fats in your diet.
Other Potential Benefits of MCT Oil
In addition to weight loss, MCT oil may offer other potential health benefits:

- Digestive Problems: Your doctor may suggest you get more MCT if you have trouble digesting other kinds of fat or if you struggle to get the nutrients you need.
- Seizures: Studies show that a high-fat ketogenic diet eases seizures. It can help some children with epilepsy who don’t react to drug treatment.
- Diabetes: Fatty acids made by MCT may help you think better when you have very low blood sugar (hypoglycemia). It may trim body fat and improve insulin resistance for folks with type 2 diabetes, but more research is needed.
- Autism: In one small study, adding MCT to a ketogenic gluten-free diet helped improve symptoms in children with autism. But more research needs to be done.
- Neurological Disorders: Some research shows MCT oil may help ease problems with thinking, memory, or judgment.
- Heart Disease: A keto diet with MCT oil can help you lose extra weight, reducing your risk of heart disease. MCT oil in your diet can also help lower LDL (the “bad”) cholesterol while also increasing your HDL (the “good”) cholesterol.
- Antimicrobial and Antifungal Effects: MCTs may have antimicrobial and antifungal effects.
