Dave Asprey is the reason a lot of people first typed “biohacking” into a search bar. Tech operator, loud experimenter, louder marketer. He turned a personal health rebuild into Bulletproof: coffee with butter and MCT oil, a diet that treated mold and inflammation as real problems, and a conference circuit where scientists shared the bill with gadget vendors. He did not invent butter tea. He did invent the consumer aisle this site still lives in.
The coffee was the gateway. Coffee, grass-fed butter or ghee, MCT. Claim: longer satiety, fewer jitters, cleaner focus. For some people it is a decent breakfast replacement. For others it is a 400-calorie latte with a manifesto. The idea underneath aged better than the brand: food as a cognitive input. That is why his name still sits near cognitive performance.
What is still useful is the posture. Change one thing. Measure. Kill it if the number does not move. Sleep trackers, EEG weekends, bloodwork. The catalog around that posture is noisier. Bulletproof, Danger Coffee, 40 Years of Zen, Upgrade Labs. A protocol and a SKU often arrive in the same paragraph.
He talked about indoor air, mold, and light years before those were default podcast topics. Some of it went maximalist detox. The boring remainder is correct: dark cool bedroom, take water-damaged buildings seriously if you are sick, stop pretending indoor air is free.
MCTs and ketones got a consumer push from him early. Dose still matters. More butter is not more optimization. Steal the experimenter’s habit. Run the rest through a simpler hierarchy (train, sleep, protein) so you do not end up with $600 of antioxidants and a 6-hour night.
