What are Medium-Chain Triglycerides (MCTs)?
Medium-chain triglycerides (MCTs) are a type of saturated fatty acid with a shorter chain length than most other fats. This unique structure allows the body to digest and absorb them more quickly, sending them directly to the liver to be metabolized into ketones. These ketones can serve as an immediate source of energy for both the body and the brain, which is why MCTs are popular among keto diet followers and athletes. While most people associate MCTs with coconut or palm kernel oil, they are also found naturally in animal-derived fats.
Goat and Sheep Milk: The Top Dairy Sources of MCTs
When searching for what dairy is high in MCT, milk from goats and sheep stands out. Studies show that the fatty acid composition of these milks includes a much higher percentage of medium-chain fatty acids compared to cow's milk.
- Goat Milk: An excellent source, with some reports indicating that 20–35% of its fatty acids are MCTs. This higher concentration makes goat milk and its products a potent dairy option for increasing MCT intake.
- Goat Cheese: Because goat milk is naturally high in MCTs, cheeses made from it also carry this advantage. Varieties like feta and other soft goat cheeses are excellent choices.
- Sheep Milk and Cheese: Similar to goat milk, sheep milk contains a high concentration of MCTs, giving sheep's milk cheese a distinct advantage in both flavor and digestibility.
Exploring Other Dairy Products with MCTs
While not as concentrated as goat and sheep products, several other dairy items contain meaningful amounts of MCTs, especially when sourced from grass-fed animals.
- Butter and Ghee: Butter contains a modest amount of MCTs, typically 5–8% of its total fats. However, the clarified form of butter known as ghee is also a good source of MCTs and is valued for its high smoke point, making it excellent for cooking. Choosing grass-fed butter or ghee can provide a superior nutrient profile.
- Cow's Milk and Yogurt: Whole cow's milk contains MCTs, but at a much lower percentage than goat or sheep milk. Full-fat yogurt, including Greek yogurt, also contains MCTs in smaller amounts. The key is to consume full-fat versions, as skimming removes most of the fat content.
The Health Benefits of Dairy-Derived MCTs
Including dairy products that are high in MCTs in your diet can offer several health benefits:
- Quick Energy: The rapid absorption and metabolism of MCTs provide a quick and efficient energy source, which is beneficial for fueling workouts or combating mental fog.
- Enhanced Satiety: Studies suggest that MCTs may help increase feelings of fullness, which can aid in appetite control and weight management.
- Metabolic Support: MCTs can boost metabolic rate and encourage fat oxidation, supporting the body's fat-burning processes.
- Improved Brain Function: Ketones produced from MCTs can serve as an alternative energy source for the brain, potentially enhancing cognitive function and mental clarity.
MCT Content Comparison: Dairy vs. Other Sources
While dairy products are a natural source of MCTs, it's important to note how they stack up against other common sources, particularly coconut oil, which is famously rich in these fatty acids.
| Food Source | Primary Animal/Plant | Approximate MCT Content (% of total fat) | Notes |
|---|---|---|---|
| Goat Milk | Goat | 20–35% | High concentration and easily digestible fats. |
| Sheep Milk | Sheep | ~21.8% | Higher MCT than cow milk, often used in cheeses. |
| Ghee (Clarified Butter) | Cow | 5–8% | High smoke point, concentrated from butter. |
| Butter (Grass-fed) | Cow | ~5–8% | Lower MCT content than goat milk, but a solid source. |
| Whole Cow's Milk | Cow | ~10.5% | Smallest proportion of MCTs among these dairy options. |
| Coconut Oil | Coconut | >60% | Richest non-dairy source, significantly higher than dairy. |
How to Incorporate MCT-Rich Dairy into Your Diet
Adding these MCT-rich dairy options to your meals is simple and delicious. Here are a few ideas:
- Goat Cheese: Crumble goat cheese on a salad with nuts and seeds, or use it to top roasted vegetables for a tangy flavor boost.
- Goat or Sheep Milk: Use it as a cow milk substitute in smoothies or coffee for an extra MCT kick.
- Ghee: Use ghee for sautéing vegetables, frying eggs, or roasting meats. Its high smoke point and rich flavor make it a versatile cooking fat.
- Grass-fed Butter: Add a spoonful to your morning coffee for a creamy, keto-friendly boost or use it for cooking and baking.
It's important to remember that while MCTs offer benefits, they are still saturated fats. Moderation is key, especially if you have concerns about cholesterol or heart health. Consulting with a registered dietitian can help you determine the right amount for your individual needs.

Conclusion: Prioritize Goat and Sheep Dairy
While most dairy contains some MCTs, if your goal is to maximize your intake from dairy sources, focus on products from goats and sheep. Goat milk, goat cheese, and sheep's milk cheese offer the highest concentrations. Butter and ghee also provide MCTs, especially if they are grass-fed. By being mindful of your source, you can effectively integrate MCTs into your diet through whole food dairy options.
