#317: Functional Medicine and Autism: Denise Voight on Key Nutrients, Blood Tests to Ask For, and the Link Between Zinc, Nutrition, and Behavior

If you're a parent, caregiver, or professional supporting a child with autism, you've likely asked: can nutrition and supplements really make a difference? Dr. Mary Barbera is joined by Functional Medicine Nutritionist Denise Voigt to explore how diet, nutrient deficiencies, and functional medicine approaches can significantly impact behavior, development, and overall wellness in children with autism. They break down the science behind picky eating, the critical role of zinc, and why a skewed zinc-to-copper ratio may be driving symptoms like agitation, sleep disturbances, and poor focus. You'll also learn what blood tests to ask for, what to look out for in low-quality supplements, and how to choose safe, high-potency options tailored for neurodiverse kids. With real-world insight and expert guidance, this episode is packed with actionable takeaways to help you better support your child’s health journey—starting from the inside out.
