    Methylene Blue on the Airplane

    Methylene blue rewires the respiratory chain, which can help you if your respiratory chain is situationally limited by hypoxia, toxicity, genetics, or nutrition, but otherwise hurts you because there is no wiring of the respiratory chain better than the one nature endowed you with.

    Chris Masterjohn, PhD


    Chris Masterjohn is the host of the Mastering Nutrition Podcast and
    founder of Mitome, where through advanced analysis of your

    electron transport chain activity, we uncover your unique cellular

    blueprint to optimize your mitochondria. His expertise is in how

    nutrition, lifestyle, and supplementation impact mitochondrial health,

    and on how to use lab testing to assess mitochondrial function

    and document the progress in mitochondrial optimization.



    He received his PhD in Nutritional Sciences from University of Connecticut
    at Storrs in 2012, served as a postdoctoral research associate in the
    Comparative Biosciences department of the University of Illinois at 
    Urbana-Champaign's College of Veterinary Medicine from 2012-2014,
    served as Assistant Professor of Health and Nutrition Sciences at Brooklyn
    College from 2014-2017, and now works independently in science research
    and education.

    Complex Nutrition

    "Chris Masterjohn’s MasterPass provides fantastic synopses of extremely complex nutrition topics. He is thorough and articulates nutrition information in ways that make sense. Fantastic!"
    Dr. Deborah Langheld ND, MPH

    Comprehensive Approach

    "Chris Masterjohn takes a comprehensive approach including 1) scholarly and critical approach by digging through the published literature, 2) functional approach by analyzing the biochemical pathways 3) understanding variability among individuals by showing what genetic polymorphisms change individual requirements. I know of no other who can do all this."
    - Harold W.

    Unique Approach

    "Very in-depth info on much of what is important for health and no commercial interests involved. Here one gets insights that one cannot find in other places and that is approached from different angles."
    Alphonse C.
