Long-term vegan and clinical dietitian Seren Wechsler is here to talk about blood work vegans should get, a few specific nutrients including B12, iron, and zinc, and his thoughts on why nutrition professions don’t get respected as they should. Hear about Seren's vegan story and his amazing 130 pound weight loss. Find out which blood work tests to ask for, how to determine your iron and B12 levels, and how can you tell whether your calcium intake is on point (hint: you can’t test it via blood work).
