Hi Dorothy,If you bought the detox products kit from the OFFICIAL website, you will not have to take the probiotic. The Innercleasne daytime and nightime formula would be in place of the probiotic.You take the innercleanse for only 14 days. So, if you opt, you can have 1 tsp. of probiotic powder (non-dairy_ with 8oz of distilled water in the AM for the remainder of the detox.
If you did not purchase the detox products from the website, then yes you are to take the probiotic for 21 days in the method stated above.
Good luck and hope to see you on the FAN page!
