It contains 3 flavors, all a bit too sour for me. Also, it took me a while to discover that unless you put it in some hot water before you add cool water, it will not dissolve well and you'll end up with a lot of powder-like wet ingredients on the bottom of your cup after you finish drinking it.
The flavor I actually liked a lot was of an extra packet that was added labeled as "immune boost" or something similar. I wish they would make more of that one.
All that said, I will continue to use this product because it is sugar free.
