Hi all I ordered the Xooma to try I did only order the sample pack which is 9.99 for 12. It also signed me up as a distributor. At anyrate after 3 days I ve noticed 2 things. 1. My water tastes crisper and 2. My Imitrix is not making me feel like I was being beaten with a bat. Both good!! I will keep you all posted. I think it is helping because it has 947 mg of calcium 34mg of magnesium . I tried calcium before and it did not seem to help so this is a pleasant surprise.
