no suppliments are taken during the cleanse.
Its clearly spelled out in the book.

you flush everything out of your so quickly.

you want to start with a parasite cleanse
then go to The Master Cleanse (always cleanse your bowels after a parasite cleanse)
and then follow up fasting by a Liver Flush to remove any stones that may have formed in the gall bladder.

i skipped the liver flush. instead i drank apple juice and ate high fat (healthy fats) until one day the pressure was relieved and i passed a bunch of white stones.

That website keeps popping up and frankly, I think its more spam than solid information. However, I'll share my story with you. Several years ago I passed an 18" long Tapeworm while doing an enema. I immediately ordered a parasite cleanse and decided to do it while also doing my third full length Master Cleanse. I progressively became weaker and weaker. The detox from the cleanse and the die off from the parasites were dumping more toxins in my body that it could handle. Finally I reached the point where I was constantly having black out spells. I stopped the Master-Cleanse on day nine and continued the parasite cleanse with good success. When ever this question comes up I recommend you do a ten day Master Cleanse to help loosen the gunk that lines the intestines where many parasites live. Then begin taking the parasite formula of choice while you are eating a light healthy diet. After a week of anti parasite herbs, begin an aggressive Bowel Cleanse to sweep out the dying critters. When that is done do a liver flush. If you are still in a cleansing mood, you can do another Master Cleanse and it will be much easier than the first.
