MCT Oil – Benefits, Drawbacks, and Side Effects

Table of Contents

Medium-Chain Triglycerides (MCTs) are a type of fat that is rapidly absorbed and metabolized by the body, providing a quick source of energy. MCT oil, derived primarily from coconut oil, has gained popularity in the wellness industry for its potential health benefits. But what exactly is MCT oil, and what are its advantages and disadvantages? Let’s delve into the world of MCT oil.

What is MCT Oil?

MCT oil, or Medium-Chain Triglyceride oil, is a supplement that is derived from fats found in certain oils and dairy products. These fats, known as medium-chain triglycerides (MCTs), have a shorter chemical structure than the long-chain triglycerides (LCTs) found in most other fats and oils.

This unique structure allows MCTs to be quickly absorbed and converted into energy by the body, bypassing the longer metabolic process that LCTs undergo. Because of this, this oil has become a popular supplement among athletes, bodybuilders, and those following a ketogenic diet, who value it for its ability to provide a quick and efficient energy source.

It’s also favored for its potential to aid in weight management, as some research suggests that this oil can help promote feelings of fullness and increase metabolic rate. Furthermore, MCT oil is often used in the world of nootropics for its potential cognitive benefits, as the ketones it produces can provide energy to the brain, enhancing mental clarity and focus.

The Benefits of MCT Oil

MCT oil has several potential health benefits:

  • Reduced Calorie Intake
     MCT oil may play a role in reducing daily calorie consumption. Unlike long-chain triglycerides (LCTs) found in foods such as olive oil and avocados, MCT’s contains about 10% fewer calories. Some studies indicate that individuals who incorporate MCTs into their diet tend to consume fewer calories throughout the day. While the exact reason for this potential effect remains a topic of research, one study highlighted that those who consumed MCT oil at breakfast ate less during lunch.
  • Support in Weight Management: MCT’s have been associated with potential weight management benefits. Some older research suggests that MCT oil could aid in reducing body weight and waist circumference. A review of randomized controlled trials found modest evidence supporting weight and fat loss benefits from MCTs. However, the quality of some of these studies has been questioned. Additionally, for those on a ketogenic diet, MCTs can help maintain the fat-burning state known as ketosis.
  • Quick Energy Source: MCTs are absorbed faster by the body compared to LCTs, making them an immediate source of energy. Their shorter chain length allows for a swift journey from the gut to the liver.
    Once in the liver, they can be used directly as fuel or converted into ketones, especially beneficial for those on a ketogenic diet.
    This rapid absorption and conversion make MCT oil a top choice for those seeking a quick energy boost.
  • Potential Fat Burning: MCT oil has been studied for its potential to enhance fat burning, particularly during physical activities. Some research suggests that athletes who consumed MCTs might utilize more fat as an energy source during exercise. However, the overall evidence is mixed, with some studies showing no significant changes in fat utilization. The potential of MCTs to aid in fat burning during exercise remains an area of interest among researchers.
  • Antimicrobial Properties: MCT oils boasts fatty acids known for their antimicrobial and antifungal properties. Studies have shown that MCTs, especially those in coconut oil, can inhibit the growth of harmful microorganisms like Candida albicans and Clostridium difficile.
    These antimicrobial effects may be attributed to specific fatty acids such as caprylic, capric, and lauric acid. However, it’s worth noting that much of the current evidence comes from non-human studies, and more human-centric research is needed.
  • Blood Sugar Regulation: MCT’s has been explored for its potential benefits for those with diabetes and metabolic syndrome. Some studies have found that diabetic individuals who consumed MCT oil experienced reductions in body weight, waist circumference, and insulin resistance. However, more recent research on MCTs and blood sugar has shown mixed outcomes. While there’s potential for it to aid in blood sugar control, more comprehensive research is needed to draw definitive conclusions.

In summary, MCT’s offers a variety of potential health benefits, each backed by varying levels of research. As always, it’s essential to consult with healthcare professionals when considering the inclusion of MCT oil or any supplement in one’s diet. 

Drawbacks and Side Effects of MCT Oil

While MCT oil has several potential benefits, it’s important to be aware of its drawbacks and possible side effects:

  • Digestive Issues: Consuming MCT oil, especially in large amounts, can lead to symptoms like diarrhea, vomiting, bloating, and cramping. Starting with a small dose and gradually increasing can help mitigate these effects.
  • Potential Weight Gain: MCT oil is calorie-dense. Overconsumption without adjusting other dietary components can lead to weight gain.
  • May Increase Cholesterol Levels: Some individuals might experience elevated LDL (bad) cholesterol levels when consuming MCT oil.
  • Possible Drug Interactions: MCT oil may interact with certain medications, particularly those for diabetes.
  • Not Suitable for Everyone: Those with liver conditions should approach MCT oil with caution due to its processing in the liver.
  • Allergic Reactions: Rarely, individuals might experience allergic reactions to components in MCT’s.

How to Use?

MCT oil, with its versatility and neutral flavor, can be incorporated into a variety of foods and beverages. Here are some popular ways to use MCT oil:

  • Morning Coffee or Tea: One of the most popular ways to use MCT oil is by adding it to your morning coffee or tea. Often referred to as “Bulletproof Coffee” when combined with butter, it can provide a creamy texture and an energy boost to start your day.
  • Smoothies: Add a teaspoon or tablespoon of MCT oil to your favorite smoothie recipe. It’s a great way to get the benefits of MCTs while enjoying a delicious drink.
  • Salad Dressings: Replace traditional oils with MCT in your homemade salad dressings. It’s a simple way to incorporate this oil into your meals.
  • Cooking: While MCT oil has a lower smoke point compared to some other oils, it can still be used for low-heat cooking or sautéing. However, it’s best not to use it for high-heat cooking methods like frying.
  • Baking: MCT oils can be a substitute for other oils in baking recipes. It can be used in cakes, muffins, and other baked goods.
  • Sports Drinks: Athletes sometimes add MCT oil to their sports drinks for an extra energy boost during workouts.
  • Supplemental Use: MCT oils can be taken on its own as a dietary supplement. Starting with a teaspoon and gradually increasing the amount can help your body adjust.


  • Start Slowly: If you’re new to MCT oils, start with a small amount (like a teaspoon) and gradually increase to avoid digestive discomfort.
  • Storage: Store MCT oil in a cool, dark place. It doesn’t need to be refrigerated, but it should be kept away from direct sunlight.
  • Check Quality: When purchasing MCT oil, look for a high-quality, pure product without added fillers or artificial ingredients.

Incorporating MCT oil into your daily routine can be simple and versatile. Whether you’re blending it into drinks, cooking with it, or taking it as a supplement, MCT oil offers a convenient way to enjoy its potential benefits.

MCT Oil as a Carrier Oil

In the world of CBD oils, MCT oil is often used as a carrier oil. A carrier oil, also known as a base oil, is used to dilute essential oils and “carry” them to your skin.
That’s because CBD is a fat-soluble compound, meaning it’s absorbed into the body along with fats. MCT oils is an excellent carrier for CBD because it is absorbed quickly and efficiently by the body. This rapid absorption can help increase the bioavailability of CBD, ensuring more of it reaches your bloodstream. Additionally, the neutral flavor of MCT oil doesn’t interfere with the taste of the CBD oil, making for a more pleasant consumption experience.

Ketogenic Diet and MCT Oil

The ketogenic (keto) diet, characterized by its low-carb and high-fat intake, aims to push the body into a state of ketosis where fats, rather than carbohydrates, are burned for energy. MCT (Medium-Chain Triglyceride) oil serves as a valuable ally in this dietary approach. Here are the top five ways MCT oil supports and enhances the ketogenic diet:

  • Rapid Ketone Production: MCTs are directly metabolized in the liver, leading to a swift conversion into ketones. This process helps elevate ketone levels in the bloodstream, reinforcing and deepening the state of ketosis.
  • Instant Energy Source: MCTs are easily absorbed and transported, offering an immediate energy boost. This is particularly beneficial for those transitioning into ketosis, providing energy as the body adjusts to burning fats.
  • Appetite Suppression: MCT oils can potentially promote the release of satiety hormones, aiding in reducing overall calorie intake and curbing cravings, both crucial for the success of the keto diet.
  • Flexibility with Carb Intake: The efficient ketone production from MCTs might allow individuals on the keto diet a bit more leeway with their carbohydrate consumption while still maintaining ketosis.
  • Enhanced Brain Function: In the absence of glucose, the brain relies on ketones for energy. MCT oil’s ability to boost ketone production can support cognitive clarity and function, a noted benefit among keto enthusiasts.

Incorporating MCT oils into a ketogenic diet can optimize the benefits of ketosis, from enhanced energy to cognitive support. As with any dietary change or supplement introduction, consulting with a healthcare professional is recommended.

MCT Oil vs. Coconut Oil

While both MCT oil and coconut oil come from the same source, they are not the same. Coconut oil contains all types of medium-chain fatty acids, but only about 50-60% of these are the types quickly metabolized into energy. On the other hand, MCT oil is more concentrated and contains primarily caprylic acid (C8) and capric acid (C10), which are the MCTs that are most efficiently converted into ketones.

Here’s a more detailed comparison:

Coconut oil is solid at room temperature and melts at about 76 degrees Fahrenheit. This is due to the presence of long-chain fatty acids, in addition to MCTs. It’s great for cooking at high temperatures due to its high smoke point and adds a distinct coconut flavor to dishes.

MCT oil, on the other hand, is liquid at room temperature. It’s more processed than coconut oil to extract the medium-chain triglycerides, which results in an odorless and flavorless oil. It’s not suitable for cooking at high temperatures, but it’s perfect for adding to smoothies, shakes, or salad dressings.

Both oils do not need to be refrigerated and should be stored in a cool, dark place to maintain their quality.

MCT Oil vs. Olive Oil

MCT oil and olive oil are both popular choices in the health and wellness world, but they have different properties and uses.

Olive oil is a type of long-chain triglyceride (LCT), which means it takes longer for the body to break down and use. It’s rich in monounsaturated fats and contains antioxidants like vitamin E. Olive oil has a robust flavor and is excellent for cooking, especially for sautéing, roasting, and making salad dressings.

On the other hand, MCT is a medium-chain triglyceride, which is quickly absorbed and converted into energy by the body. It’s flavorless and odorless, making it a versatile addition to smoothies, coffee, or salad dressings. However, it’s not suitable for cooking at high temperatures.


MCT oil, with its unique properties and potential health benefits, has carved a niche for itself in the wellness industry.

Its rapid absorption and conversion into energy make it a favorite among athletes, keto enthusiasts, and those seeking cognitive and metabolic benefits.

However, like any supplement, it’s essential to approach its use with knowledge and caution. While it offers several advantages, it’s not without potential drawbacks.

As always, individual needs and reactions can vary, so it’s crucial to consult with a healthcare professional before incorporating MCT oils or any supplement into your routine. As the world of nutrition continues to evolve, MCT oils stands out as a fascinating and beneficial component worth exploring.
