Tired of feeling foggy or drained before lunch? If your brain and body aren’t firing on all cylinders, the issue might be what you’re eating—or what you’re not. Medium-chain triglycerides (MCTs) are a unique type of fat that your body absorbs quickly and converts into clean, fast energy.

As a nutritionist, I often recommend MCT-rich foods to clients looking to sharpen focus, support brain function, and boost daily energy levels—especially during that mid-morning slump. Whether you’re building a better breakfast or fueling up for a workout, MCTs can make a noticeable difference.

So, what exactly are MCTs—and where can you get them? Keep reading to learn how they work and discover nine natural foods that are rich in MCTs and easy to add to your diet.

What are MCTs?

MCTs are a type of fat molecule made up of medium-length fatty acid chains. They differ from long-chain triglycerides (LCTs), which are more common in most dietary fats.

Because MCTs have a shorter chain length, your body digests them more quickly and easily. They can be quickly absorbed and metabolized, making them a unique source of energy that stands out from other forms of fat.

Thanks to this fast-processing nature, MCTs are often used in medical nutrition, athletic fueling, and low-carb or ketogenic diets.

Quick energy source

MCTs are rapidly absorbed by the liver and turned into energy, making them a fast, efficient fuel source. This makes them especially useful before workouts, during fasting windows, or when you need a midday pick-me-up.

May support cognitive function

Because MCTs provide an alternative fuel source for the brain, they may help with focus, clarity, and cognitive performance. The Alzheimer’s Drug Discovery Foundation shares optimistic information about how “some evidence suggests that there may be short-term cognitive benefits from taking MCTs, including for patients with dementia.”

Supports weight management

MCTs may promote satiety (feeling full) and slightly increase calorie burn, which is why they’re often included in ketogenic and low-carb diets. That said, they’re not a magic bullet—sustainable weight loss still requires a calorie deficit and regular movement.

9 natural foods rich in MCTS to include in your diet

Here are some whole-food sources of MCTs to add to your meals or snacks:

  1. Coconut oil: Coconut oil is one of the richest sources of MCTs, containing about 62-65% MCTs. It is versatile for cooking and baking, and it can also be used in smoothies or coffee to boost energy and mental focus.
  2. Palm kernel oil: Palm kernel oil is another excellent source of MCTs that is similar to coconut oil and provides a quick energy boost. It can be used in cooking or as a salad dressing alternative, though sourcing sustainably is vital for environmental reasons.
  3. MCT oil: As the name suggests, MCT oil is a concentrated form of MCTs, typically derived from coconut or palm kernel oil. It can be added to smoothies, coffee, or salads to quickly increase your MCT intake without altering the taste of your food.
  4. Grass-fed butter: Grass-fed butter contains small amounts of MCTs, along with healthy fats and vitamins. It can be used for cooking or added to your morning coffee as a source of quick energy.
  5. Cheese: Cheese, particularly full-fat varieties, contains small amounts of MCTs. It provides a source of protein and fat, making it a satisfying snack or addition to meals.
  6. Whole milk: Whole milk has trace amounts of MCTs, especially when compared to low-fat or skim milk. It provides a creamy texture to smoothies or coffee and can be a good source of calories for those on a calorie-dense diet.
  7. Greek yogurt: Greek yogurt, particularly full-fat options, offers a moderate amount of MCTs. It’s a great snack, providing protein and probiotics while supporting gut health and overall nutrition.
  8. Coconut milk: Coconut milk contains MCTs and offers a dairy-free alternative to regular milk. It can be added to smoothies, curries, or baking recipes for added richness and flavor.
  9. Coconut meat: Coconut meat, especially dried or fresh, is rich in MCTs. It makes a delicious and nutritious addition to smoothies, granola, or snack mixes, offering fiber and healthy fats alongside MCTs.

Are MCTs safe? What to watch out for

While MCT-rich foods offer various benefits, there are some downsides to consider, including the following:

  • Digestive issues: Overconsumption can lead to digestive issues, including stomach cramps, diarrhea, and bloating, especially if you are just starting to consume MCTs.
  • High in calories: MCTs are calorie-dense, so while weight management is one of its perks, it could still contribute to weight gain if not consumed in moderation.
  • Gut microbiome disruption: MCTs can disrupt gut bacteria balance in some individuals, leading to gastrointestinal discomfort.

Start small and monitor your body’s response. Many people tolerate whole-food sources better than supplements.

While it is always beneficial to prioritize whole foods, MCT supplements can be a good option for you if you are:

  • On a ketogenic or low-carb diet
  • Practicing intermittent fasting
  • Needing a portable, fast fuel source for workouts or travel

However, start with small amounts (e.g., 1 tsp/day) and build gradually to avoid digestive upset. Whole-food sources may be gentler on the stomach.

When in doubt, check with a healthcare provider—especially if you have liver concerns or digestive sensitivities.

Mixing fashion and function with an NFL star: Ja’Marr Chase teams with Fabletics to find his confidence
Baseball Cap, Cap, Clothing

We look up to athletes for a lot of reasons. They are the gladiators of our day. They enter an arena and put their bodies on the line specifically for our entertainment. But to do that, there has to be a commitment. A mindset to shoot for the best of the best and devote everything you are to the perfection of your battle. For us, we tend to revere those men who reach the peak of human performance and want to recreate it in the best way we can. Sure, we can follow their fitness routines, but deep down we know we’ll likely never come close. So, instead, we buy their gear. The things they wear to perform and to chase their own glory. Michael Jordan revolutionized this with his shoes, and now the top athletes recreate it with their own collections.

Ja’Marr Chase, Cincinnati’s #1 wide receiver, chose Fabletics to be his vessel of greatness, and his third drop with the brand goes beyond the gridiron, and we got a chance to go beyond it with him.

Meet the man legendary athletes trust: Therabody founder talks us into recovery
Conversation, Person, Clothing

When I was in the Army, I woke up at 4 am (my clock no longer has two fours), and I would just get to running eight miles. Then go back to bed. No stretching. No warm-up. No cool down. It was never a problem. I am no longer twenty; I am sorry to say. And that means my body needs more. As a matter of fact, it needed more way back then too. I got an opportunity to sit down with chiropractor and recovery expert Dr. Jason Wersland, the man behind that percussive massage gun you have seen at every gym, every yoga studio, and even a lot of office buildings. What was it about his creation under his company, Therabody, that took over the wellness and recovery industries? I asked him. And I dug into why us guys have a hard time accepting that we’re getting older and need to spend more time in prep and recovery.

Just do something. The small decisions you make every day – moving your body, prioritizing sleep, managing stress, taking a few minutes to recover – they compound over time. That’s where real change happens. – Dr. Jason Wersland, Founder, Therabody

Rumble Boxing vs. Learning the Sweet Science in Mexico City: HIIT Workout or Hit Your Opponent?
Clothing, Footwear, Shoe

First and foremost, anyone who dares throw on boxing gloves and headgear to step into a ring deserves all the respect in the world. It doesn’t matter if you’re sparring in a boxing gym, going three rounds as an amateur, or fighting a sanctioned match. It’s the kind of moxie you can’t help but admire.

Second of all, I won’t lie to you and tell you that my boxing journey began inside a hot and humid boxing gym, like the ones Rocky Balboa trained in during Rocky and Rocky II; far from it. I was 6 years old when I saw my first fight: Julio Cesar Chavez vs. Meldrick Taylor for the WBC light welterweight championship of the world in 1990. I became obsessed with the sport thanks to Oscar De La Hoya’s marvelous run in the 1992 Summer Olympics in Barcelona, where the Golden Boy from East Los Angeles won the gold medal. I told Oscar as much when I interviewed him at length in 2023.
