Coconut oil primarily contains an MCT called lauric acid (C12), which has some immune system benefits. Use coconut oil for baking and cooking up to 350°F. We distill Brain Octane Oil and MCT Oil to isolate C8 and C10, the most ketogenic MCTs.[7] You’d have to eat a lot more coconut oil to get the same ketone energy as Bulletproof MCT oils.

Use Bulletproof MCT oils when you want to boost your ketones, supplement your diet with quality fats and upgrade your meals and beverages with fat-burning, brain-powering fuel.[1][5][6][7]

If you haven’t used MCT oil before, you might experience stomach upset or diarrhea. Start with just a teaspoon (or even less) to give your body time to adjust.

Yes, you can cook with MCT oil in recipes up to 320°F; like pesto, sautéed veggies, smoothies and more. Did you know? Oil accentuates fat-soluble flavors. Brain Octane Oil and MCT oil give your meals an extra kick of metabolism-boosting, brain-powering fuel.[1][5][6]

You can use MCT oil outside the kitchen. Use it to moisturize your skin and hydrate your scalp and hair. Check out 10 Ways to Use Brain Octane Oil (and Only One is Coffee).

Not at all. However, some people struggle to eat low-carb and enough high-quality fats to stay in ketosis. Plus, C8 MCT oil—what you’ll find in Brain Octane Oil—is a powerful way to efficiently boost your ketone levels and stay in ketosis.[7]

No. The term “MCT oil” can refer to four different strains: C6, C8, C10, and C12. Brain Octane Oil is C8 MCT oil, the most ketogenic part of coconut oil.[7]

High-quality MCT oil is a powerful way to support your brain. That’s because C8 MCT oil turns into ketones within minutes.[7] Ketones quickly cross the blood-brain barrier and can be used as a fuel source for brain cells, giving you steady energy.[12][13]
