Bulletproof Brain Octane C8 MCT Oil Softgels deliver 1,000mg of pure caprylic acid per capsule in a portable, mess free format. Ideal for travel, the office, or any time blending oil into a drink is not practical, these softgels contain the same triple distilled C8 MCT as the liquid Brain Octane, the most ketogenic medium chain triglyceride derived exclusively from coconuts. Each capsule rapidly converts into brain powering ketone energy.
Created by Dave Asprey as the cornerstone of the Bulletproof lifestyle, Brain Octane is made from 100% caprylic acid (C8), the most effective MCT for producing ketones. While most MCT oils contain a mix of C8, C10, C12, and other medium chain triglycerides, Brain Octane is pure C8, which converts to ketones faster and more efficiently than any other MCT. This means you get maximum cognitive and metabolic benefits from every serving.
Medium chain triglycerides are unique fats that bypass normal fat digestion. Unlike long chain fatty acids found in most dietary fats, MCTs are absorbed directly from the small intestine into the bloodstream and transported straight to the liver where they're rapidly converted into ketones. Ketones are an incredibly efficient fuel source for your brain and body, providing clean, sustained energy without blood sugar spikes or crashes.
C8 MCT (caprylic acid) is the most ketogenic of all MCTs, converting to ketones within minutes of consumption and producing more ketones per gram than any other MCT. Research shows that C8 is approximately four times more effective at raising ketone levels than C10 (capric acid) and far more effective than C12 (lauric acid) which many companies include in MCT oil as a cheap filler despite its minimal ketogenic properties.
Brain Octane undergoes the rigorous Bulletproof Process to ensure purity and quality. The C8 is extracted from fresh coconuts using a triple distillation process that concentrates the caprylic acid while removing any contaminants. Unlike many MCT oils processed with harsh chemicals or hexane, Brain Octane is refined using clean processes that maintain the integrity and purity of the C8. The result is the cleanest, most effective MCT oil available.
The cognitive benefits of Brain Octane are profound. Ketones produced from C8 MCT provide an alternative fuel source for your brain that's more efficient than glucose. Your brain preferentially uses ketones when available, and this ketone energy supports improved mental clarity, improved focus and concentration, faster cognitive processing, sustained mental energy without crashes, reduced brain fog, and better memory and learning. Many people report feeling noticeably sharper and more mentally alert within 30 minutes of consuming Brain Octane.
For energy and metabolism, Brain Octane provides rapid, sustained energy by converting to ketones within 15 to 30 minutes. Unlike carbohydrates that cause blood sugar spikes followed by crashes, ketone energy is stable and sustained for hours. Brain Octane also helps curb cravings and reduce hunger by promoting satiety, supports metabolism by encouraging your body to use fat for fuel, supports metabolic rate, and provides clean energy for workouts without digestive heaviness.
Brain Octane is the perfect addition to Bulletproof Coffee, the signature drink that started the movement. Simply blend coffee with grass-fed butter and Brain Octane to create a creamy, satisfying, energising beverage that provides hours of sustained energy and mental clarity. The combination of caffeine from coffee, quality fats from butter, and rapid ketone production from Brain Octane creates synergistic effects far greater than any ingredient alone.
Beyond coffee, Brain Octane is incredibly versatile. It's completely flavourless and odourless, so you can add it to smoothies, protein shakes, salad dressings, sauces, soups, and virtually any food or beverage without affecting taste. This makes it easy to incorporate ketone producing C8 MCT into your daily routine regardless of your eating preferences or dietary approach.
For those following ketogenic diets, Brain Octane is invaluable. It helps you get into ketosis faster, maintain deeper ketosis, and recover ketosis quickly after consuming carbohydrates. The rapid ketone production from C8 means you can support ketone levels quickly without strict carb restriction, making keto more flexible and sustainable. Brain Octane also helps ease the transition into ketosis by providing ketone energy before your body fully adapts to using fat for fuel.
