Bulletproof's Brain Octane C8 MCT Oil is sourced purely from coconuts, and converts into brain-powering, fat-burning ketone energy. It helps control cravings and improves cognitive performance to keep you sharp. Bulletproof Brain Octane Oil is flavourless, so add it to smoothies, salad dressings, Bulletproof Coffee and more.
C8 MCT oil is 100% caprylic acid triglycerides harvested from the most ketogenic part of the coconut. Caprylic acid, a medium-chain triglyceride (MCT), is an energizing, easy-to-digest quality fat. C8 MCT oil turns into ketones within minutes. Ketones quickly cross the blood-brain barrier and can be used as a fuel source for brain cells, giving you steady energy.
Bulletproof was founded by biohacker and entrepreneur Dave Asprey, who set out to optimise human performance through science-backed nutrition. Inspired by his own health journey, he created Bulletproof to offer high-quality, functional nutrition designed to fuel both body and mind. From supplements to coffee, every product is thoughtfully sourced and formulated to support energy, focus, and resilience—helping you unlock your full potential and discover what better feels like.
