The parasites are probably creating your anemia. Some of them love iron. If you feed them iron, they grow stronger. Eliminate the parasites and then work on the anemia. Best to eliminate most supplements as they probably feed the parasites. One exception seems to be zinc. Another may be Vit D, since it is the basis of most of our immune system.
Pump up your fiber intake, make sure you have plenty of stomach acid and digestive enzymes working before you cleanse. You should be having at least 2 bowel movements a day before you cleanse for parasites. Don't cleanse if you are constipated.
Eliminate any raw, smoked, pickled, salted or undercooked meats. No ceviche. The Jews and Muslims were right to eliminate pork. They just carry too many parasites. Either wash all of your veggies well or just eat cooked ones. Sugar and carbs feed parasites. Starve them of both. Fruit is sugar.
