Chris Masterjohn explores why citrate or malate supplements might cause insomnia, presenting two hypotheses: metabolic issues (which he favors) versus mold contamination.

Chris Masterjohn explores constipation, covering its definitions, causes like dyssynergic defecation and slow transit, and critiques standard treatments such as laxatives for low efficacy.

Chris Masterjohn analyzes a case study of Iris, who developed food intolerances and other symptoms from years of excessive omega-3 intake.

Chris Masterjohn explores the biology of hair graying, explaining it involves neuroendocrine signaling, oxidative stress, and energy metabolism.

Chris Masterjohn answers a listener question about the vitamin and mineral cofactors required for synthesizing and recycling BH4 (tetrahydrobiopterin).

Dr.

This episode examines claims about whether natural vitamin C from whole foods is superior to synthetic ascorbic acid, particularly regarding its relationship with copper and the tyrosinase enzyme complex.

This episode critically analyzes Gary Brecka's appearance on Joe Rogan, supporting his nutrition advocacy but challenging his oversimplified focus on five genes and methylation while agreeing on broader health principles.

This episode challenges the common belief that hormones control health issues, arguing instead that hormone abnormalities are symptoms of underlying biochemical imbalances related to nutrition, body composition, and energy availability.

This episode explores biotin's extensive health benefits beyond hair and nails, including its role in preventing deficiency symptoms like mood issues, vision problems, high cholesterol, and complications in diabetes and pregnancy.

This episode explains the biochemical process of how lactate actually alkalinizes muscles during exercise, debunking the common misconception that it acidifies them.

This episode clarifies that the primary issue with seed oils is oxidative damage to lipids, which can drive conditions like atherosclerosis, and directs listeners to specific educational resources for deeper understanding.

This episode explores how nutrition can optimize cognitive performance by comparing it to drugs like cocaine, using historical examples from Sigmund Freud and Weston Price.

Dr.

This episode reveals four overlooked biomarkers that are crucial for understanding mitochondrial function, energy metabolism, and optimizing health beyond conventional lab tests.

This episode addresses whether long-term use of NAC as a biofilm disruptor could damage the gut's mucus layer, explaining biofilms and their protective functions.

This episode explores the complex relationship between high-dose vitamin C and glutathione in cancer treatment and general health, highlighting how vitamin C acts as a pro-oxidant against cancer cells while needing balance with glutathione to avoid oxalate issues.

This episode explores how energy metabolism, governed by the second law of thermodynamics, serves as the fundamental root cause of autoimmune conditions in relation to gut and nutritional issues.

This episode explores how personalized genetic testing can reveal unique health 'super unlocks' by challenging conventional wisdom about carrier status for genetic diseases and its impact on metabolism.

This episode explores how glycine might help with an exaggerated startle reflex, discussing its neurobiology, links to anxiety and PTSD, and factors that enhance or inhibit the reflex.

This episode explains how to protect against oxalates in meals by using calcium to bind them in the digestive tract and maintaining proper urine pH to prevent kidney stone formation.

This episode explains why keeping postprandial blood glucose under 140 mg/dL is important to avoid activating the polyol pathway, which can impair NADPH supply and antioxidant recycling.

This episode explores methylene blue's medical applications, mitochondrial effects, and risks, distinguishing it from a general health supplement.

This episode explores the anecdotal side effects of creatine supplementation, such as insomnia, cramps, and hair loss, and uses biochemical reasoning to discuss potential causes and solutions.

This episode exposes the hidden dangers of SSRIs, revealing that withdrawal symptoms stem from mitochondrial dysfunction and highlighting the discrepancy between clinical trial data and real-world experiences.

Dr.

This episode examines the usefulness of hair tissue mineral analysis (HTMA) for monitoring minerals and heavy metals in the body, discussing its role as an optional add-on in comprehensive nutritional screening.

This episode explores the connection between depression and mitochondrial function, explaining how altitude affects oxygen availability and ATP production, and discusses the role of methylation and supplements like SAMe in mental health.

This episode argues that aging is fundamentally caused by declining mitochondrial function, which creates a vicious cycle of reduced energy production and repair capacity over time.

This episode critiques how medical practice prioritizes treatment-focused models over detailed causal factors like seed oils in heart disease, using examples from depression and epilepsy to illustrate the binary decision-making approach.
