You might have heard about medium chain triglycerides, also called MCT. These fats have a special shape. This shape helps your body use them for energy fast. You can find MCT in foods like coconut oil, palm kernel oil, and dairy foods. People use MCT for many reasons:
It helps your body take in fats better if you have trouble digesting food.
You can use it for quick energy, and it helps your body use fat and protein.
Athletes use it to help them last longer and burn more fat.
Some doctors say it can help stop weakness in older people.
It may help your body make ketone bodies for special diets, like for epilepsy or cancer.
Scientists are checking if it can help people with dementia remember things better.
Key Takeaways
Medium chain triglycerides (MCTs) give you fast energy. Your body takes them in faster than other fats. MCTs can help you lose weight. They make you feel full and help you eat less. Adding MCT oil to your food can help athletes. It can make them perform better and recover faster. MCTs may help your gut stay healthy. They fight bad bacteria and lower swelling. Start with a little MCT oil to avoid stomach pain. Slowly use more over time.
Medium Chain Triglycerides
What Are Medium-Chain Triglycerides
Medium chain triglycerides are a special kind of fat. They belong to a group called triglycerides. Triglycerides are the main fat in food and your body. Medium chain triglycerides have shorter fatty acid chains than most fats. These chains have 6 to 12 carbon atoms. There are three main types:
C8 is caprylic acid. It has 8 carbon atoms.
C10 is capric acid. It has 10 carbon atoms.
C12 is lauric acid. It has 12 carbon atoms.
You can find medium chain triglycerides in coconut oil. They are also in palm kernel oil and some dairy foods. These fats are different because your body absorbs them quickly. When you eat mct, your body does not need much work to break them down. You get energy faster than with other fats.
Note: Medium chain triglycerides have two or three medium-chain fatty acids. These attach to a glycerol backbone. This helps them move fast through your digestive system.
Chemical Structure
Medium chain triglycerides have a special structure. Each mct has a backbone called glycerol. Three fatty acids attach to this backbone. The main difference is the length of these fatty acid chains.
Type of Triglyceride | Chain Length | Metabolism Characteristics | Common Sources |
|---|---|---|---|
Medium-Chain | 6-12 carbon atoms | Rapidly metabolized by the liver, quick energy source | Coconut oil, palm oil, dairy |
Long-Chain | 13-21 carbon atoms | Metabolized slowly, stored in fat cells | Butter, beef, pork, olive oil |
Short-Chain | Fewer than 6 carbons | Absorbed quickly, rapidly metabolized | Less common in diet |
Medium chain triglycerides have shorter chains than long-chain triglycerides. This makes them more water-soluble. Your body sends them straight to the liver. There, they turn into energy or ketones. Long-chain triglycerides need more steps to break down. They often get stored as fat.
MCT vs Other Fats
Mct are different from other fats in your diet. The main difference is how your body digests and uses them.
Mct have shorter fatty acid chains than long-chain triglycerides.
Your body digests and absorbs mct faster. Long-chain triglycerides need bile salts for digestion.
Mct go straight to your liver. Your body uses them for quick energy or turns them into ketones.
Long-chain triglycerides take longer to break down. They are more likely to be stored as fat.
“Eating medium- and long-chain triglycerides (MLCTs) helps your body process long-chain triglycerides (LCTs) better in overweight people. This means MCTs may help your body use LCTs faster.”
Medium chain triglycerides act differently in your body. Studies show animals fed mct have more ketones in their blood. This means your body can use mct to make ketones. Ketones are another energy source, especially during low-carb diets. Long-chain triglycerides do not raise ketone levels as much.
Medium-chain fatty acids from mct move quickly to your liver. They travel through the portal vein. Your liver uses them for energy right away. This means your body stores less of these fats. Long-chain fatty acids take longer to reach the liver. They are more likely to be stored as fat.
“This study showed that triolein (LCT) and trioctanoin (MCT) are absorbed at different rates. Infusing trioctanoin made it harder for the body to absorb triolein. This shows that medium and long-chain triglycerides compete during absorption.”
Mct give your body energy fast. They also help your body make ketones. This can help with certain diets or health problems.
How MCTs Work
Digestion and Absorption
When you eat foods with mct, your body starts to break them down right away. This process begins in your mouth and stomach. Lingual lipase, an enzyme in your saliva, starts to work on the fat. In your stomach, mct are partially broken down even more. Your body does not need to wait for the small intestine to start using these fats.
Once mct reach your small intestine, your body releases bile into the duodenum. Bile helps break the fat into tiny droplets. This step makes it easier for enzymes to work. Pancreatic lipase, another enzyme, quickly digests mct into smaller parts. This process is faster and more efficient than with long-chain fats.
Here is how your body digests and absorbs mct:
Lingual lipase in your mouth and stomach starts breaking down mct.
Pancreatic lipase in your small intestine finishes the job quickly.
Your body does not need to form chylomicrons for mct. This is different from long-chain fats.
Mct move straight into your bloodstream through the portal vein.
Your liver receives mct fast and starts using them as an energy source.
This quick process means your body can use mct for energy almost right away. You do not store much of this fat. Instead, your body sends it to the liver for rapid use.
Energy and Metabolism
Your liver plays a key role in turning mct into energy. When mct reach your liver, they go through rapid oxidation. This means your body burns them quickly to make energy. You get a fast energy source, which is why athletes and people on special diets often use mct.
Mct stand out because your body does not store them as fat easily. Instead, your liver uses them right away. This makes mct a preferred energy source when you need quick fuel. Your body also uses mct to make ketones. Ketones are another energy source, especially when you eat fewer carbs. If you follow a ketogenic diet, mct can help your body make more ketones. This process supports your brain and muscles when glucose is low.
Medium chain triglycerides, especially those with 8 or 10 carbon atoms, boost ketone production in your liver. When you take mct as a supplement, your blood ketone levels rise. The more mct you take, the more ketones your body makes. This effect helps people who need extra ketones for health reasons.
You might wonder how much energy you get from mct compared to other fats. Studies show that mct give you a slightly higher energy yield than long-chain fats. Here is a simple table to compare:
Metric | MCT (kcal/min) | LCT (kcal/min) | Fat Oxidation (g/min) | Fat Oxidation (g/min) |
|---|---|---|---|---|
Average EE | 0.95 | 0.90 | 0.080 | 0.075 |
This table shows that mct provide a bit more energy per minute than long-chain fats. Your body also burns more fat per minute when you use mct as an energy source.
Tip: If you need quick energy for sports or a busy day, mct can help your body deliver fuel fast.
Medium-chain triglycerides work differently from other fats. Your body absorbs and uses them quickly. They give you a fast energy source and help your liver make ketones. This makes mct useful for athletes, people on low-carb diets, and anyone who needs quick fuel.
Sources of MCTs
Natural Foods
You can find mct in several foods you eat every day. Coconut oil stands out as one of the richest sources. Palm kernel oil also contains a high amount of mct. Dairy products like butter, whole milk, cheese, and Greek yogurt provide smaller amounts. The table below shows how much mct you get from each source:
Food Source | MCT Content (per serving) |
|---|---|
Coconut oil | 8 to 14 g per tablespoon |
Palm kernel oil | 7 to 8 g per tablespoon |
Coconut cream | 3 to 5 g per ¼ cup |
Grass-fed butter | 0.7 g per tablespoon |
Whole milk | 0.8 g per cup (10.5% of fat) |
Cheese | Lower amounts |
Greek yogurt | Lower amounts |
Coconut oil contains about 50-60% lauric acid. Lauric acid is a medium-chain fatty acid, but your body may process it more like a long-chain fat. Palm kernel oil also has mct, but the exact amount can change. Dairy foods give you mct, but the levels are much lower than in coconut or palm kernel oil.
Tip: If you want to add more mct to your diet, start with coconut oil or palm kernel oil. These oils give you the highest amounts in just one serving.
MCT Oil
Mct oil comes from natural sources like coconuts or palm kernels. The process to make mct oil involves several steps:
Harvest coconuts or palm kernels.
Separate the medium-chain triglycerides from other fats.
Purify the mct to remove anything unwanted.
Blend different mct fractions to get the right mix.
Test each batch for quality and safety.
Package the oil in airtight containers.
You can use mct oil as a supplement. Many people add it to coffee, smoothies, or salad dressings. Mct oil gives you quick energy and is easy to digest. Doctors sometimes recommend mct oil for people who have trouble absorbing fat or nutrients. You might use mct oil if you want to manage your weight, control your appetite, or get extra energy for exercise. Some people use mct oil to help with digestive problems, seizures, or inflammation. Mct oil may also support people with pancreatic insufficiency or those who need more ketones for special diets.
Note: Mct oil does not have much taste or smell. You can add it to many foods without changing the flavor.

Mct helps your digestive system too. These fats can fight bad bacteria in your gut. They also help lower swelling in your body. You may have better gut health and less chance of stomach problems.
Finding | Description |
|---|---|
Antimicrobial Properties | |
Inflammation Reduction | MCTs lower inflammation in your liver. |
Intestinal Permeability | MCTs help your gut work better. |
Gut Microbiota | MCTs support healthy gut bacteria. |
If you eat a ketogenic diet, mct can help you get into ketosis faster. Your body makes more ketones. This gives your brain and muscles extra energy. Doctors use the ketogenic diet with mct to help people with epilepsy, diabetes, and Alzheimer’s disease. Some studies show mct may help memory and thinking, but results are not always the same.
Side Effects
Most people can use medium chain triglycerides safely. Studies show mct is safe when you use normal amounts. You might get a stomach ache, diarrhea, or cramps if you take too much. Start with a small amount to see how your body feels. Side effects are rare if you use mct as part of a healthy diet. If you have liver problems or trouble digesting fat, talk to your doctor first. Kids, pregnant women, and people with some health problems should be careful.
Tip: Always start new supplements slowly and watch for any changes in your health.
Using MCTs
How to Add MCT Oil
You can add mct oil to your meals in many simple ways. Many people wonder how to use mct oil in their daily routine. You might start your day by blending mct oil into your morning coffee or tea. This creates a creamy drink that gives you quick energy. Some people enjoy making smoothies or shakes with mct oil powder for a boost before or after exercise. You can also mix mct oil into salad dressings with olive oil and apple cider vinegar. If you like to cook, try using unrefined coconut oil to roast vegetables at low to medium heat, but keep the temperature below 350°F. Coconut oil works well in curries and soups, adding flavor and healthy fats. You can fry plantains in shallow oil or make keto “fat bombs” for a snack.
Tip: MCT oil has a low smoke point. Avoid using it for high-heat cooking to prevent burning and keep its health benefits.
If you want to know how to use mct oil without stomach upset, start with small amounts. Large servings may cause nausea, cramps, or diarrhea, especially on an empty stomach.
Dosage and Safety
You should begin with a small dose of mct oil. Most experts suggest starting with one teaspoon (5-7g) per day. After a few days, you can increase to one tablespoon (14g). Some people use up to two tablespoons (28g) daily, but you should listen to your body and go slow.
Dosage Level | Amount of MCT Oil |
|---|---|
Starting Dose | 1 tsp (5-7g) |
Intermediate Dose | 1 tbsp (14g) |
Maximum Recommended | Up to 2 tbsp (28g) |
Some people may need to avoid mct oil. If you have allergies to coconut or palm oil, liver problems, or certain digestive disorders, talk to your doctor first. Pregnant or breastfeeding women should also check with a healthcare provider. Too much mct oil over time may raise cholesterol or cause fat buildup in the liver. Always watch for side effects and adjust your intake if needed.
