Since I couldn’t find any site for prebiotics through Dr. Kara, I am having to write on this website: let the buyer beware. I decided not to try the prebiotic after receiving. Unable to find a mailing address, I called the company to find out where to return. It took three tries. I had received a postcard included with the order which said money back guarantee "even if containers were empty." I have tried three times to get the address to return. When I took the package to post office, there was no address such as given. After I tried again today, I was given the runaround again, so I finally gave up, called my credit card company and let them dispute.
Never ever again will I purchase anything like this from the internet. Beware of this site! I am giving one star only because you have to give something in order to post.
Bottom Line: No, I would not recommend this to a friend
