Great Taste
I have heard that Magnesium is best absorbed in powder form. However, it is hard to find one that tastes good. Kalmassure Magnesium Powder with the orange flavor tastes great. It reminds you of Tang which we used to drink as kids.

Best magnesium of this type
I bought this after trying two other brands. This magnesium is hands down the best tasting and easiest to mix for drinking.

Does not mix well
I got this as a replacement magnesium supplement I was buying at a local vitamin store. I have used it for 4 days and find that it does not mix well in water. I am using 1 scoop in 8 oz of water but there is always a significant amount left at the bottom. I even tried drinking all the mix and then adding more water to what is left in the bottom. It is still not mixing. I will not buy this product again.
