Not bad. Not too bad, at all
I’ve only tried the strawberry lemonade flavor. It’s not a fantastic taste, but it’s not bad. I add it to 2-4 oz of water then follow with a plain water “chaser”.  I’m not 💯% convinced of the nutritional value. I did not give a 5-star rating because it’s sweetened with DEXTROSE. Yuk. Nasty taste and bad for you. If they’d use stevia, beet root or other more healthy sweetener I’d give it a 5.
