Discover how to supercharge your immune health by harnessing the power of these key vitamins and minerals. In this in-depth video, we’ll reveal how these micronutrients help maintain barrier integrity, balance T cell responses, and support overall immune function – all backed by the latest clinical trials and research (from the common cold to COVID-19).

We’ll also cover important but often overlooked topics like deficiency signs, over-supplementation pitfalls, and the real risks of toxicity or hypervitaminosis. Learn how certain high-dose supplements can lead to potential issues such as nerve damage, kidney stones, and dangerous medication interactions. Whether you’re curious about nutrient deficiency testing, looking for practical supplementation tips, or simply want to optimize your body’s natural defenses, this video has you covered!
