Product history
David Asprey developed his Bulletproof Coffee recipe after traveling to Tibet and tasting yak-butter tea drinks. He returned to the United States and experimented with buttered drink recipes and published the preparation for his buttered coffee drink on his blog in 2009.
In 2014 Bulletproof Coffee was featured on shows such as Good Morning America, Today and The Tonight Show with Jimmy Fallon, and had a following of over three million consumers. By 2015, Bulletproof was operating with 20 employees and had over six million unique visitors to its website. The stand-alone Bulletproof Cafe opened in Los Angeles that same year.

Historical antecedents
Coffee drinks made with butter and other forms of fat have been in use for centuries by people from the Himalayas, Ethiopia, Nepal, Vietnam, and Singapore. In Ethiopia, the Gurage people traditionally add butter, honey and salt to coffee. In Vietnam and Singapore, chon coffee beans are commonly sautéed with butter prior to roasting. Butter tea is a popular drink in Tibet, where its high calorific content provides energy to those performing manual labor in a harsh environment.
Preparation
Asprey's recipe calls for brewing coffee with "upgraded" beans which Asprey claims are low in mycotoxins. To this 1-2 tablespoons of grass-fed, unsalted butter (or ghee) and 1-2 tablespoons of "Brain Octane" oil (a mostly 8-carbon octanoic acid fraction of MCT oil) are added. The drink is then blended for 20-30 seconds until frothy.
Health claims
Asprey has claimed that when used in combination with other "health hacks," the coffee helped to boost his IQ score by more than 20 points. His company claims that Bulletproof Coffee can aid cognition and trigger weight loss through ketosis.
Dietitians point out there is no scientific basis for these claims, and that any sense of alertness from Bulletproof Coffee is "just a caffeine buzz." Some physicians like Dr. Frank Lipman and Dr. Andrew Weil believe that, when combined with a balanced diet, drinking buttered coffee could be healthy and "might give you a bit more energy than your everyday cup."
Asprey claims that most coffee beans contain high levels of mycotoxins and that this "steals your mental edge and actually makes you weak." He sells a brand of "upgraded" beans which are advertised as having undergone a secret, proprietary process to reduce mycotoxin levels. However, Physician David Bach has observed that coffee producers are already good at removing mycotoxins from their product, and that there is no evidence to support Asprey's claim that mycotoxins make people "sluggish".
