I was taking 4,000 mg a day of C, so he said I could back off it. (Understand, I am taking literally hundreds of $$$ of supplements a month, so we are looking for places I can cut back after overhauling my nutrition.) Plus, I’m also getting small amounts through other supplements. I’ve also stopped taking magnesium and calcium. He said they don’t recommend calcium, since we are able to process what we need from food if we are balanced in other nutrients/supplementation and excess just winds up in the soft tissues causing other problems. And magnesium only if seeing issues with sleep or muscle cramping. I’m also stopping selenium, which he had recommended after lab testing for micronutrients and has now balanced out.
