I first met Dr. Walsh in the fall of 2014, at his second physician training course here in the US. At the time, I was uncertain how useful nutrients would be in my psychiatric practice. What I learned seemed too good to be true. Upon returning home, I gradually began evaluating and treating specific nutrient imbalances in adults and children with depression, ADHD, anxiety, bipolar disorder, autism spectrum disorders, and so on. To my repeated surprise, most patients - children and adults alike improved… significantly - some dramatically, including those whose symptoms had failed to respond to other treatments.
