You have to make sure you are getting the proper nutrition that your body needs. For me, it has been a trial and error process to figure out what my body needs. I like to get as much as I can from diet, but I need lots more iodine, some extra selenium (250-500 mcgs/day), potassium, magnesium and salt. Make sure you are getting plenty of B vitamins and Anti-oxidents. I take these as needed, when I am traveling, holidays, etc, when I am "unable" to eat "right"...
Iodine, Iodine, Iodine. It is a key mineral for revitalizing cellular integrity. Almost everybody is extremely deficient. If your cells are healthy, the parasites won't try to compost you. They are only programmed to decompose unhealthy tissue, ie sickly cells. I repeat: Iodine helps to fortify the cells.
