Detailed product information

Bulletproof Brain Octane Oil is a premium MCT oil that is able to metabolise effortlessly in the body providing a fast and clean source of sustained energy. MCT Oil may help to improve cognitive performance and reduce cravings, and provides an excellent source of healthy fats for those on a ketogenic diet.

>> Increased Energy

Brain Octane Oil is made exclusively from medium-chain caprylic acid (C-8) which is easy to digest and may fuel your cells more efficiently than coconut oil. Caprylic acid converts into energising ketones that start powering your cells within minutes. This significantly enhances ketone production in the body, giving you a clean and sustained source of energy for mental and physical performance.

>> Improve cognitive performance

Brain Octane Oil contains Medium Chain Triglycerides which can give you a rapid, long-lasting brain boost. Caprylic acid provides ketones as a direct energy source to the brain, which may provide cognitive benefits. Ketones are able to pass the blood-brain barrier leading to improved focus and mental clarity. Studies have shown that C-8 chain fatty acid MCTs enhance cognition and improve memory.

>> Reduce cravings and support healthy weight management

Brain Octane Oil may help reduce cravings and energy crashes and help you feel full for longer. The C-8 chain fatty acids are a very efficient source of fuel for cells, and can help to jumpstart your metabolic rate.

Bulletproof Brain Octane Oil is completely flavourless and is liquid at room temperature, making it easy to pour AND easy to use.

  • Blend it into Bulletproof Coffee or tea
  • Add to smoothies and shakes
  • Drizzle it over your favorite meals
  • Use to make salad dressings, sauces, and marinades

Start using Brain Octane one teaspoon at a time and increase slowly over several days. Use up to 1-3 tablespoons per day. Too much Upgraded Octane Oil, especially if consumed on an empty stomach, can result in loose stools or a stomach ache.

Brain Octane Oil is made from 100% caprylic acid triglycerides, or C8 from coconut oil and is harvested from the most ketogenic part of the coconut.

Caprylic triglycerides are compounds made of naturally occurring fatty acids. They're a clear liquid and slightly sweet to the taste. The high fat content in triglycerides, along with their texture and antioxidant qualities, make them a great addition to your diet.

High-quality (caprylic acid) MCT oil is a powerful way to upgrade your brain. The easy-to-digest caprylic acid fuels your cells efficiently and converts into fat-burning ketones within minutes with C8 MCT Oil. Ketones quickly cross the blood-brain barrier and can be used as a fuel source for brain cells, giving you steady energy unlike carbs and sugar. So you help avoid cravings and, energy crashes!

Brain Octane Oil is flavourless, so you may use this any way you like, making it a great addition to any diet. You can use up to 1 – 3 tablespoons per day. You may add this to whatever you're drinking or eating. Drizzle over salads, vegetables for a supercharged keto salad dressing or steak as a finishing oil. You can also blend into smoothies or coffee or use it in recipes up to 320°F.

Adults can use Brain Octane Oil to help improve cognitive performance and reduce cravings.

You’ll surely get more ketone benefits if you’re on a low-carb diet. But this particular MCT oil (pure caprylic acid, or C8 MCT) is a special type of quality fat that’s good for you in many ways outside of ketosis. Brain Octane Oil boosts ketone production, curbs cravings and gives you sustained energy, whether or not you’re on the keto diet.
