Before you begin cleansing, you'll probably want to know some stuff. We'll tell you what we know based on our long and happy experience with cleanses, but keep in mind we're not doctors. We're very bright, but we're not licensed to give medical advice. That said, we have lots of nutritionist friends and customers who swear by our cleanses, and there's a lot of info online about our ingredients and their benefits...although it's pretty hard to argue with apples and carrots and celery.
