I was told by my doctor that they absolutely would only be able to find eggs in watery stool and instructed me to take magnesium citrate to make it so. I did that before I started the parasite cleanse. I did two samples before the cleanse and one after I started it. I had been taking HCL and digestive enzymes all the while though. I figured it may be better if the parasites were purged out in the sample for obvious reasons but who knows. I won't find out for a while still.
