On this episode of Bulletproof Radio, we have carefully selected the best questions from Facebook, Twitter, and the Bulletproof® Forums for another awesome Q&A!  Thanks to you, the listener! Hear a thought-provoking conversation and gain a ton of useful knowledge in this episode about the art of biohacking, nutrition, and… well… kicking ass at life in general! Dave and Zak talk about supplements and how they affect the gut, what they feed their kids, how to be Bulletproof® on a budget, and why grass fed butter is way better for you than raw crème in your Bulletproof® Coffee (not to mention ten times cheaper too!). It’s been a while since the last Q&A, so please enjoy the show!
