ABSTRACT

An entrepreneur named Dave Asprey is making a fortune with “Bulletproof Coffee,” a blend of caffeine, butter and medium-chain triglyceride oil derived from coconut oil that supposedly increases energy and imparts cognitive clarity. Asprey’s “biohacking” podcast called Bulletproof Radio, where he describes the formula’s effects, was downloaded 10.5 million times in 2014 alone (Megroz, 2015).
