MCT (Medium Chain Triglyceride) oil has become one of the most widely used supplements in the keto community — and for good reason. Unlike long-chain fats, MCTs are rapidly absorbed and converted to ketones.
MCTs are fatty acids with 6–12 carbon chains. The most abundant in supplements are caprylic acid (C8) and capric acid (C10), both found naturally in coconut oil.
MCT oil rapidly elevates blood ketones, providing quick mental clarity and energy. It also increases fat oxidation and may suppress appetite.
C8 (caprylic acid) is the most ketogenic MCT and converts to ketones fastest. C10 follows. Regular coconut oil contains only about 60% MCTs, so dedicated MCT oil is more effective.
Start with 1 teaspoon per day to avoid digestive discomfort (loose stools are common at first). Work up to 1–2 tablespoons over 2–3 weeks. Add to coffee, smoothies, or salad dressings.
The most popular MCT oil application: blend black coffee with 1 tbsp MCT oil and 1 tbsp butter for a creamy, ketone-boosting morning drink. Check our keto beverages for more ideas, and our keto snacks for MCT-boosted fat bombs.
