Your immune system runs on vitamins and minerals, but more isn’t always better. This video breaks down exactly which nutrients support your immune system and the doses that can quietly backfire.

We cover how vitamins A, B, C, D, E, and K, along with the key minerals zinc, selenium, and iron, actually support immunity, from strengthening your barriers to producing antibodies to calming inflammation. You’ll learn the best food sources for each nutrient, who’s most at risk of a deficiency, and why mega-dosing supplements can sometimes do more harm than good. The goal is balance: getting enough to support immune function without tipping into excess. Every claim in this video is grounded in peer-reviewed research, and the full reference list is included below so you can check the science for yourself.
