High-dose biotin supplements can cause a multitude of false lab tests, masking recent heart attacks, pregnancies, or allergies, giving false signals about tumors, and far more. In this episode, I lay out for you the nature, scope, and magnitude of the problem, and develop actionable strategies you can use to protect your lab tests from generating false information as a result of this phenomenon. You can find the written and fully referenced version of this episode here: https://chrismasterjohnphd.substack.com/p/biotin-causes-false-lab-tests The written version also contains some figures that help you visualize the mechanistic information.

My simple food-based recommendations for getting enough biotin are found in my Cliff Notes (free for Masterpass members here). To learn more about the Masterpass, click here.
