I looked for the La Croix today at ShopRite (I'm in NJ) and couldn't find it, but I DID find something called Cascade Ice with a sparkling coconut flavore (0/0/0 and no phosphoric acid). They have a number of other flavors as well. I just go5t one coconut to try it and it's AMAZING! Now I have to order the WF chocolate to go with it.
Someone who knows more than I can take a look an be sure it is OK for us! THey also have Organic versions if you prefer that.
