MCT oil has gained immense popularity in recent years, especially among those following a ketogenic diet. But with so many options available, how do you choose the best MCT oil for keto? This article delves into the world of MCT oil, exploring its benefits, different types, and top product recommendations to help you make an informed decision.
What is MCT Oil?
MCT oil is a supplement derived from medium-chain triglycerides (MCTs), a type of saturated fat. MCT molecules are smaller than those in most dietary fats, which are long-chain triglycerides (LCTs). This smaller size makes MCTs easier to digest and allows for quicker absorption into the bloodstream. Once absorbed, MCTs are rapidly converted into energy that your body can readily use.
MCT oil is typically sourced from coconut or palm kernel oil, both of which contain MCTs. The extraction process, called fractionation, separates and concentrates the MCTs from the original oil. You can find MCT oil in two forms: 100% MCT oil and mixtures of MCTs and LCTs.
Potential Benefits of MCT Oil
MCT oil is often used to support various health goals, including:
- Fat Absorption Issues: MCT oil may be beneficial for individuals who have difficulty digesting or absorbing fats.
- Weight Loss: Some studies suggest that MCT oil may promote weight loss by increasing feelings of fullness and reducing calorie intake.
- Appetite Control: MCT oil may help regulate appetite by influencing hormones that control hunger and satiety.
- Increased Energy: MCT oil provides a quick source of energy, which can be beneficial for exercise or daily activities.
- Reduced Inflammation: MCT oil may possess anti-inflammatory properties, potentially reducing inflammation in the body.
- Ketone Production: MCT oil can aid in the production of ketones, an alternative energy source for the brain that doesn't rely on carbohydrates.
- Cognitive Function: Some research suggests that MCT oil may improve cognitive function, particularly in individuals with neurological disorders.
- Skin Health: The lauric acid in MCT oil has antimicrobial properties, which may help treat skin infections.
While these potential benefits are promising, more research is needed to fully understand the effects of MCT oil on these conditions.

Understanding MCT Composition
MCT oil typically contains a combination of different medium-chain fatty acids, each with unique properties and benefits. The main types of MCTs include:
- Caproic Acid (C6): The shortest MCT, caproic acid, is present in small amounts and has a pungent odor and taste. It may contribute to energy production and antimicrobial effects.
- Caprylic Acid (C8): This MCT makes up a significant portion of most MCT oil products and is known for its rapid conversion into ketones, providing a quick energy boost for the brain. It may also support cognitive function and fat oxidation.
- Capric Acid (C10): The second most abundant MCT in MCT oil, capric acid, has potential antiviral properties and may support immune function.
- Lauric Acid (C12): Although technically an MCT, lauric acid behaves more like a long-chain fatty acid in the body. It has antimicrobial properties and may contribute to skin health.
MCT Oil and Ketosis
The ketogenic diet is a very low-carb, high-fat diet that forces the body to burn fat for energy instead of carbohydrates. This process leads to the production of ketones, which become the body's primary fuel source.
MCT oil can be a valuable tool for those following a keto diet because it helps the body produce more ketones than LCTs. This may help individuals reach the fat-burning phase faster and maintain ketosis more easily. Additionally, MCT oil may allow for a slightly higher carbohydrate intake while still staying in ketosis, making it easier to include fruits and vegetables in the diet.
MCT Oil for Specific Conditions
MCT oil may offer potential benefits for certain health conditions. However, it's essential to consult with a healthcare professional before using MCT oil to manage any medical condition.
- Digestive Problems: MCT oil may be recommended for individuals with difficulty digesting fats or absorbing nutrients due to conditions like pancreatic problems, small bowel resection, or short bowel syndrome.
- Seizures: A ketogenic diet high in fat can help reduce seizures in some children with epilepsy who don't respond to drug treatment. MCT oil can make the keto diet easier to follow due to the high amounts of fat.
- Diabetes: MCT oil may improve cognitive function during hypoglycemia in individuals with type 1 diabetes. It may also help reduce body fat and improve insulin resistance in those with type 2 diabetes, but more research is needed.
- Autism: One small study showed that MCT oil, combined with a ketogenic gluten-free diet, improved symptoms in children with autism. However, further research is necessary.
- Neurological Disorders: MCT oil may help improve thinking, memory, and judgment in individuals with neurological disorders like Alzheimer's disease.
- Heart Disease: A keto diet with MCT oil may promote weight loss, reducing the risk of heart disease. MCT oil may also help lower LDL ("bad") cholesterol and increase HDL ("good") cholesterol.
How to Use MCT Oil
MCT oil can be easily incorporated into your diet. Here are some common ways to use it:

- Smoothies: Add a tablespoon of MCT oil to your favorite smoothie for a boost of healthy fats and energy.
- Salad Dressings: Use MCT oil as a base for homemade salad dressings.
- Coffee: Mix MCT oil into your morning coffee for a creamy, energy-boosting beverage known as "bulletproof coffee." Start with one teaspoon and gradually increase to one or two tablespoons.
- Direct Consumption: Some people take MCT oil directly from a spoon.
- Finishing Oil: Drizzle MCT oil over cooked dishes as a finishing oil to add healthy fats and flavor.
Avoid using MCT oil for frying due to its low burning point.
Potential Side Effects and Precautions
While MCT oil is generally safe for most people, it's important to be aware of potential side effects and precautions:
- High Calorie Content: MCT oil is high in calories, which can contribute to weight gain if consumed in excess.
- Saturated Fat: Large amounts of saturated fat may raise cholesterol levels.
- Hunger Hormones: MCTs may stimulate the release of hunger hormones, potentially leading to overeating.
- Liver Fat Buildup: High doses of MCT oil could lead to fat buildup in the liver.
- Gastrointestinal Distress: Consuming large amounts of MCT oil may cause stomach pain, gas, cramps, bloating, diarrhea, or vomiting.
To minimize potential side effects, start with a low dose (one teaspoon) and gradually increase as tolerated. It's also important to include other healthy fats in your diet, as MCT oil doesn't contain essential fatty acids.
Choosing the Best MCT Oil: Factors to Consider
When selecting an MCT oil, consider the following factors:
- Source: Opt for MCT oil derived from coconut oil, as it generally contains a higher concentration of beneficial MCTs.
- MCT Composition: Determine your desired MCT composition based on your health goals. For a quick energy boost, choose an oil rich in caprylic acid (C8). For sustained energy, opt for a blend of caprylic and capric acid (C10).
- Purity and Quality: Look for MCT oil that is third-party tested for purity and free of additives, fillers, and artificial ingredients.
- Organic Certification: Choose organic MCT oil to minimize exposure to pesticides and other harmful chemicals.
- Form: MCT oil is available in liquid, powder, and softgel forms. Choose the form that best suits your preferences and lifestyle.
- Brand Reputation: Research different brands and read customer reviews to assess the quality and effectiveness of their MCT oil products.
