'The Better Brain is the first book that will tell you both how and why nutrients can be used to treat mental-health issues. We are scientists who've uncovered that many symptoms of anxiety, depression, ADHD, PTSD and more are caused by suboptimal nutrition. We've been doing research and clinical studies on this crucial topic for decades, yet we have never published our findings for a general audience before. Following our lectures and Julia's TEDx Talk, we get asked questions all the time about our findings and why nutrients are so important for our brains. People want to know more. They're desperate for answers. This is our solution.'
