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.

In High Protein? You Need More Biotin, I made the case that 30 micrograms per day is not enough for adults, and that many people need 150-300 micrograms per day, depending on how much protein they eat.

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.
