It takes some balancing to keep Vit D levels in a good place for Immune System and keep from becoming constipated. I work with the magnesium, extra Vit C, a new product which is a cleanse called Intestinal Movement Formula, and have Psyllium powder on its way..and my trusty cooked prunes. Keeping a balance is important and also being mindful of colon clogging foods like heavy meats.. and drinking warm water thru the day, aim for 8 glasses warm water..
