Frequently asked
Questions people ask before buying
What format is it?
A 162-page PDF, downloaded immediately after purchase. It reads on a phone, a tablet or a desktop, and it is laid out with 52 pictures and tables rather than as a wall of text.
Is this written by AI?
No. The guide was written by two named authors, a neuropsychologist and a medical doctor, and every claim in it is backed by an academic reference. There are 739 of them. The books popularize scientific insights and discoveries, they do not generate them.
Do I need to buy supplements to use it?
No. The guide covers foods, herbs, spices and habits alongside supplements and nootropics, and it is explicit about what the evidence supports. Talk to your own doctor before starting any supplement.
Is this the same as Gut Mastery?
No, though they overlap at the gut-brain-microbiota axis. Gut Mastery is about digestive problems and their protocols. This guide is about feeding the brain, and it treats the gut as one of the routes to doing that.
