Chris Masterjohn

Chris Masterjohn, PhD, a nutritional scientist and host of the Mastering Nutrition podcast, delves into fascinating topics around mitochondria and nutrition. He debunks the turkey-tryptophan myth and reveals how sleep acts as mitochondrial rest. Masterjohn discusses the broader benefits of creatine beyond muscle performance, including cognitive health, and highlights the importance of sunlight for producing glutathione. He also warns about megadosing nutrients and emphasizes a food-first approach to health, advocating for diversified exercise and testing for mitochondrial stress.

Dr. Chris Masterjohn, PhD, nutrition scientist focused on micronutrients, metabolism, and mitochondrial health. He explains why mitochondrial function limits energy and progress. He highlights micronutrient bottlenecks, creatine as cellular energy wiring, and why sunlight and vitamin D pills are not equivalent. He outlines practical strategies like testing, sleep, varied exercise, and targeted supplements.

Chris Masterjohn, a biochemist and nutrition scientist, dives deep into the complexities of serotonin and SSRIs. He challenges the notion that SSRIs are solely mood boosters, revealing their potential disruption of mitochondrial function. Masterjohn emphasizes the role of brain energy metabolism and argues that exercise and nutrition can outperform medication in treating depression. He also highlights the benefits of morning sunlight on serotonin levels and mitochondrial activity, suggesting new pathways for understanding and addressing mental health.

Chris Masterjohn, nutritional scientist and mitochondrial biology expert who founded Mitome, explains why cellular energy matters. He recounts clashes over COVID messaging and social media, outlines a mitochondria-first approach to health, and describes personalized mitochondrial testing, altitude and light therapies, and why diet and lifestyle often deserve priority over quick pharmaceutical fixes.

Chris Masterjohn, PhD, nutritional scientist and founder of Mitome, explains translating mitochondrial biology into practical testing. He discusses the sigma-1 receptor and its role in stress and mitochondria. Conversations cover how SSRIs differ in sigma-1 activation, the energetic roots of withdrawal symptoms, breathwork and hypoxic training, and a food-first approach for mitochondrial health.
