Chris has offered suggestions to my questions I would have never thought of or come across myself, & it's comforting to know I'm receiving advice from someone with such great depth & breadth of knowledge (for example how nutrition relates to neuroscience, etc.). I cannot recommend this product enough!"

"I've been studying health and nutrition for decades so sometimes it's hard to remember specific critical things. This guide is the perfect document to refer to as it's only 27 pages yet it's full of important information. And unlike a physical book it's very easy to do a search for specific terms."
