Question: What to do about sky-high pyroglutamate?

Pyroglutamate, its other name is 5-oxoproline. It is something that is primarily produced when you are synthesizing glutathione, but you do not have enough of the second step in glutathione synthesis to keep up with the first step.

Maybe you need more glycine, but your glycine isn't low enough to cause orders of magnitude higher pyroglutamate. It's almost certainly the case that you have a glutathione synthetase deficiency, unless you have extraordinary levels of oxidative stress. I think that would be easy to test for because I just can't imagine that your glutathione levels -- I guess it's not that easy to test for because if you have a glutathione synthetase defect, you're going to have bad glutathione levels. If you have a tremendous amount of oxidative stress, you're also going to have low glutathione levels. If you have low glutathione levels, that's going to cause a tremendous amount of oxidative stress.
I think if it's not a glutathione synthetase defect, then it becomes a lot harder to figure out what it is because it probably means you have massive oxidative stress from somewhere and there's a lot of things that could cause that. That would be a potential Pandora's box of questions that would come out of that. But definitely the first step would be to look at glutathione synthetase.

Chris Masterjohn, PhD, is the Founder and Scientific Director of the mitochondria test Mitome.


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.
