Dr. Andrew Hill is a neuroscientist and friend of mine that is quite the expert at brain health and the field of nootropics and biofeedback. He has worked for several companies developing nutritional supplements like myself and we have a discussion about what supplements you can use to optimize your mental performance in a SAFE manner. If you are in need of functional lab testing to measure how your mind and body are functioning, check your vitamin D status, inflammation and much more, please visit http://im.notjustpaleo.com/shop to view your options. As always, email me at notjustpaleo@gmail.com with any questions.
