About Daniel

Daniel T. Johnston, MD, MPH is board certified by the American Board of Preventive Medicine and serves currently for the Army Surgeon General and performs clinical duties at the US Pentagon in Executive Medicine (disclaimer: these opinions are my own and do not necessarily reflect those of the US Army or US Government). He has served in the US Army for almost 20 years in a variety of clinical, research, operational and educational assignments. Assignments at the Pentagon, White House, Iraq, Korea and beyond led him to change his view of health from absence of disease to optimal brain-body coherence and functional capacity at the cellular/neuron level. Working closely with Dr. Bill Harris who had perfect RBC fatty acid analysis as a marker of tissue levels, he was the first to conduct a study in Iraq leading to a peer reviewed publication demonstrating the massive epidemic of fatty acid deficiencies in the US, particularly young people, and the link of cellular Omega-3 EPA/DHA Index status to cognitive health. Working with Dr. Bill Harris, Dr. Johnston built upon an advanced, validated red cell, finger stick dried blood spot collection method into a full clinical decision support tool that combines functional analysis of the brain so blood data is seen through the lens of functional implications. He also founded BrainSpan (clinical decision support tool based on fatty acid blood status and brain function) that works with leading clinical nutritional companies to drive patient awareness, compliance and adherence critical to improved outcomes. Dr. Johnston and Bryan Hixson were the first to develop an age based, weighted algorithm leveraging predictive analysis to paint a picture of a patient’s longevity and quality of “brain” life based on Omega-3 EPA/DHA status and cognitive function over a specific time frame and 2-3 individual tests.
