This guide provides my recommendations for nutritional and herbal defense against COVID. This version covers 41 randomized controlled trials, which are the gold standard of evidence, as well as many other studies providing context for interpreting the trials. Since much of this research is recent, not all of it is peer-reviewed. However, I have used my own expertise in nutritional sciences and extensive experience evaluating research to fully review the quality of this evidence myself. This protocol represents the best of science-backed strategies for nutritional and herbal anti-COVID defense.

The gold standard of evidence in medicine is the randomized, controlled trial, or RCT. In RCTs, people are randomly given a treatment, or not. That this is determined at random means people's health, behavioral traits, and choices play no role in the outcomes. This helps us be more confident the treatment really works, or doesn't work.

We now have 41 RCTs on the ability of nutrients, herbs, or other natural compounds to fight COVID. While these trials are usually small, some haven't been peer-reviewed yet, some are funded by supplement manufacturers, and most haven't yet been replicated by different researchers from different institutions and different parts of the world, they are the best evidence we currently have and serve as the highest priority evidence used in this guide.

In evaluating these trials, the most important things I looked for were whether the trials were done well, whether the data were reported clearly, and whether the interpretations were sound. However, I also considered the funding source, whether different groups had come to similar results, how much of the data was peer reviewed, and whether the substance is an essential nutrient.

Based on these considerations, I categorized anything that made the cut into three tiers: "Essentials," "Best Add-Ons," or "These Might Help." Having better quality, more trustworthy, more consistent data, and having essential nutrient status pushed the strategies up toward the Essentials tier, while lacking these qualities pushed them down toward the "These Might Help" tier. Those with intermediate support are included as Best Add-Ons.

The guide includes suggestions on how to tailor the protocol to your individual needs, your personal risk, your environmental risk, and your own risk tolerance. It also includes full instructions on how to implement the strategies.

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.
