James- I am also following a Nutritional Balancing program with Trace elements. My current testing has suggested I take Betaine HCL with pepsin. I take a very high doseage of these. Before I was taking Now Super Enzymes which are very good and inexpensive from Swanson's. I think many of us struggling with parasites have very low stomach acid and low mineral levels as well. A long standing infection just strips the body of all mineral reserves.
