I've been taking this for 2 weeks now and I gained weight. After doing a little research I found out that one of the ingredients is a laxative so really the weight you do lose, if any, will reappear when you stop taking Xenitol. Very disappointed with the results and I suggest anyone who wants to try Xenitol should do their research first. I personally won't be trying this product again.
I use this product when I overindulge in fatty or carb loaded food. This allows for a good splurge now and then without the weight gain. Although you will be in the bathroom a little more, it does work well.
