My husband agrees on Runa. I bought him 5 different flavors and he has tried 2 and couldn’t get past 2 sips either time.
I finally found the bai Boost and absolute love it!!
I found it at Walmart and no it is not carbonated. It has 1 net carb, 1 g sugar, 10 mg sodium, 10 calories but 110 mg caffeine per bottle. I have tried the watermelon & tangerine, but not the berry yet.
My understanding is the development team is working on a resolution for the duplicate item issue. As soon as I learn more about where that's at, I'll post an update.
