I've heard a lot about nutrient depletion being the cause of several symptoms. What's interesting is all the talk about how many medications strip vitamins from our bodies, which is causing this nutrient depletion. My doctor told me to use Mytavin, which is a calculator that shows how your meds are depleting you. I live a pretty healthy life, but I recently went to the lab and found out my thyroid wasn't functioning because of a lack of nutrients. Any thoughts on this?
