18x Stronger Than Coconut Oil – For Maximum Cognitive Function!

Upgraded Brain Octane (C-8 MCT) rapidly metabolises into ketones, providing almost instant energy to the brain without requiring glucose from dietary sugars or carbohydrates. This makes it the top choice for reaching peak brain performance all day, especially during demanding tasks or during Bulletproof® Intermittent Fasting. Upgraded Brain Octane also has potent anti-microbial effects that help to support healthy digestion and immune function. Also available in a smaller size: Brain Octane - 473ml

Upgraded™ Brain Octane (C-8 MCT) may provide the following benefits:

  • Fast energy for the brain – Brain Octane converts into energy faster than other fats or oils*
  • Fuels a starved brain – Brain Octane delivers much needed ketones to fuel a starved brain than can no longer efficiently metabolize glucose for energy*
  • Reduces brain fog – Slaughters the gut yeast, candida, responsible for producing 180+ toxic chemicals in the blood stream*
  • Rebalancing of yeast in gut – Brings candida into balance
  • Does NOT increase blood cholesterol – Metabolized differently than other types of fat*
  • Make meals more Bulletproof – Flavorless and easy to add into diet. Mix into any smoothie, soup, sushi, coffee or most recipes, for more intense mental activity
  • Flavorless and odorless to add to any liquid or food*
  • Easy Storage – No refrigeration required and liquid at room temperature
  • Replaces far more expensive versions – Upgraded Brain Octane is only 25% the cost of weaker Caprylic Acid capsules ($1.07 per oz. versus $3.78 per oz)

Unique High Quality Processing

Most caprylic acid comes with an unpleasant goat-like smell and taste, but we use a unique, time consuming, proprietary process to reduce free fatty acids. Upgraded Brain Octane is completely tasteless and odorless – perfect for mixing with foods to bring out their flavors!

Brain Octane Oil is 100% derived from sustainable coconut oil, with zero palm oil mixed in.

What's the difference to Upgraded XCT Oil?

  • Upgraded Brain Octane contains only C-8 carbon medium-chain triglycerides (MCT) from coconut and sustainably sourced palm kernel. This particular MCT is designed for optimal cognitive function and we've had feedback that it's great for focus and productivity while studying / working.
    Upgraded XCT Oil contains both C-8 and C-10 length chains. C-10 is more closely associated with metabolic functions ­ ie. it is better suited for weight loss and a physical energy boost.
