Bulletproof coffee was originally created by Dave Asprey, aka The Bulletproof Executive. It's designed to kick-start your day by replacing carb-heavy breakfasts with a nourishing, energy-boosting alternative. Bulletproof coffee contains coffee made from high quality, low-toxin coffee beans, with either coconut oil or some other kind of medium chain triglyceride oil (aka MCT oil), and grass-fed butter or ghee.
