<<Disclaimer: Verify this information before applying it to your situation.>> Hi again, I noticed this drink in the refrigerated juice aisle of my grocery store and my curiosity got the best of me. I called, and all their flavors are gluten-free. The person I talked to offered to send me a letter stating that and signed by her and the nutritionist. I've never tried it, so have no idea about the taste or the claims they make on their website, which is: www.nuvim.com So, just in case you're curious like me, now you know.
