It depends on what you're treating for. Candida is not something that goes away with a cleanse and some maintenance. It's a lifestyle change and long term battle that, can sometimes take years. Some of the posters here have been dealing with it for the better part of a decade. If parasites are your concern then yes, I believe a few good, productive cleanses and some maintenance and you'll be good. However, all of this depends on how badly you have either issue.
