You don't have to do the parasite cleanse unless you fit the profile. :) You can Liver Flush many times and if vital health has not returned, consider doing the parasite flush. I never had to.
Triphala is great. Milk Thistle will make the liver work harder, which makes us tired.
Primal Defense should be taken after thoroughly cleansing the colon. Gradually increase dosage, take it until the bottle is halfway gone, save the rest for maintenence doses about once a month or so from then on.
