Question: Is dairy safe for overmethylators?

There's so little methylcobalamin in milk that I think that it is totally insignificant with regards to methyl groups, coming into the methylation cycle. Generally, if you're experiencing over-methylation symptoms from methylcobalamin or methylfolate, I think the big issue is partly that you don't have enough glycine in the system, very likely, and partly that your body is over-accustomed to low methyl supply and putting more suddenly into it leading into the system being adapted to a different state than the one you're putting into it. But if you find it is, you're reacting to dairy, I would be very surprised if it was the methylcobalamin, but if you're very convinced of that, then titrate up slowly with the dairy.

Chris Masterjohn, PhD hosts Mastering Nutrition, a podcast that digs into the science of how our bodies work at a fundamental level. The focus here is on mitochondrial health-the energy powerhouses within our cells-and how optimizing them forms the cornerstone of lasting vitality. Chris brings his background as a nutrition scientist and his experience founding BioOptHealth to these conversations, which move beyond generic diet advice. Instead, the podcast explores how individual differences, informed by tools like whole genome sequencing and detailed biochemical data, can reveal personalized paths to better metabolic function. Listeners will hear deep dives into cutting-edge research, practical interpretations of complex studies, and discussions on how to apply these insights in a real-world context. This isn't about quick fixes or trending superfoods; it's about building a coherent, scientifically-grounded understanding of nutrition from the cellular level up. Each episode aims to provide the kind of nuanced, evidence-based perspective that can help you make sense of conflicting health information. Whether the topic is a specific nutrient, a metabolic pathway, or a broader principle of wellness, Chris works to translate dense science into actionable knowledge. Tune in for a thoughtful, detailed exploration of what it truly means to master your own nutritional landscape.
