The Supplements, Foods, and Habits I Use to Stop a Cold Before It Starts

About this episode

Why do some people catch every cold going around while others rarely get sick? Your immune system isn’t something you simply “boost” with one supplement—it’s shaped every day by your sleep, diet, stress, gut health, nutrient status, and metabolic health. In this episode, I’m joined by one of my producers, Emma, to break down what actually helps you build a more resilient immune system before cold and flu season hits. Here’s what we discuss in today’s episode: Why some people get sick constantly while others seem far more resilient What actually weakens your immune system long before symptoms show up What I personally do at the first sign of a cold or flu The most important habits and nutrients for supporting immune function through the winter You don’t need a complicated immune protocol. The goal is to strengthen the systems that help your body respond well when you’re exposed—so you’re less fragile when cold and flu season arrives.
