BE VERY CAREFUL WHEN TRYING THEIR FREE TRIAL. In their Term and Conditions, which is hidden at the bottom of the website, it states that you only have 14 days to cancel or they will charge your card $89.00. They don't make you agree to this, in fact, they hide it pretty well, so DON'T sign up for this product if you are not willing to take a hit, because they will hit your credit card whether you like it or not. Below is the wording of their terms and conditions:

When you order the Free Trial of Natural Cleanse your credit card will be charged only $4.95 shipping and handling.
As part of the trial period, you will receive a one month supply of Natural Cleanse and you will have 14 days from your original purchase date to decide if Natural Cleanse is right for you. If you are enjoying Natural Cleanse, then do nothing and at the end of your 14 day trial period your credit card will be charged the full price of $89.00 for your first month's supply.
If you find Natural Cleanse is not right for you, simply contact our Customer Service Department to cancel your membership within 14 days of your original order date and you will not be charged any additional fees (you will have only been charged the $4.95 for shipping and handling).
Approximately 30 days from your original purchase date and every 30 days thereafter you will be sent another one month supply of Natural Cleanse and your credit card on file will be billed $89.00 plus $4.95 shipping and handling.
Limit one trial offer per household.
