Common Questions About MCT Oil

What does MCT oil do?
MCT oil provides a fast source of fuel that can support energy, focus and ketone production. Many people add MCT oil to their daily routine to support productivity, workouts, fasting protocols and ketogenic lifestyles.

Brain Octane® Oil contains 100% C8 caprylic acid, while Bulletproof™ MCT Oil contains a blend of C8 and C10 MCTs, making it a versatile option for everyday energy and wellness support.
If your goal is maximum mental performance and ketone support, Brain Octane® Oil is typically the preferred choice. For daily use, coffee, smoothies and general wellness, MCT Oil is a great option.
Can I put MCT oil in coffee?
Yes. MCT oil is commonly added to coffee to provide a source of healthy fats and clean energy. It can also be blended into smoothies, protein shakes, salad dressings and other recipes.
