Unique cotton candy profile
Given what it is, the flavor profile and range (energy, electrolytes and protein) I think this is a great product. The flavor might be a bit of an acquired taste. I for one love cotton candy although I can be a bit of a stickler on flavor accuracy. This tastes like cotton candy. It could easily be used in a multitude of recipes for smoothies or otherwise as well. This was my first time trying this brand or this product either one, It's a win for me. Not all caffeine is equal either, this is well rounded in my opinion. There is a slight aftertaste and a distinct chalkiness to it, but it is bearable. I recommend taking more than one sip when first trying this product and chilling it beforehand. Can't imagine this tastes good at room temp.

THe Best
This is the best product to drink when you can’t have milk. It’s smooth, easy on the stomach, and still gives you that creamy taste without the discomfort. I love how light it feels but still satisfying. Definitely a great alternative for anyone who is lactose intolerant or avoiding dairy.

Cotton candy: taste good for sweet cravings and caffeine needs
It’s really sweet, if you’re craving something sweet it’s nice though. It also has caffeine so great for the morning boost. Or pre workout. Very convenient protein on the go. Taste good if your into sweets. I gave 5 stars because it does taste good, just sweet. Still wish it was cheaper. No chalkiness, decent ingredients. Be aware IT HAS CAFFEINE!!!! Drank one at bed time not noticing the caffeine content stayed up all night.

Great drink but should be caffiene free
This is a pretty good tasting drink. I do enjoy it but you definitely get that protein aftertaste. I like it having protein and electrolytes and I would've given 5 stars if it didn't have 125mg of caffiene. I ordered this for the flavor and electrlytes not the energy. Worth trying once if you enjoy cotton candy but I think its a one time buy.

Sweet, refreshing and functional!
I was a little skeptical at first, but this cotton candy flavored protein water surprised me in the best way! The flavor is sweet and light—like a hint of cotton candy without being overpowering or too sugary. It feels refreshing instead of heavy, which makes it perfect after a workout or even as a mid-day pick-me-up. I also love that it gives me a boost of protein without the thickness of a shake. Sometimes I don’t want something creamy, and this is the perfect alternative. It’s smooth, easy to drink, and doesn’t leave a chalky aftertaste like some protein products do. If you’re someone who struggles to get enough protein in or just wants a fun, nostalgic flavor that doesn’t feel like “health food,” this is definitely worth trying. Sweet, refreshing, and functional—exactly what I was hoping for!

Protein Without the Aftertaste Trauma
Light, refreshing, and doesn’t taste like regret. Easy to drink, easy on the stomach, and actually enjoyable. Perfect when you want protein without committing to a thick shake.

Tastes Like Medicine🤢
I love Protine2o, but Cotton Candy, I do not. It literally tastes like Medicine. Almost Nyquil like, but not as bad. It is drinkable, but barely. I don't know how I'm going to get through 11 more of these and they're too expensive to through out. Look though, I meant it, I do love this product. I've had every flavor and besides Cotton Candy, the only other one that is terrible is Orange. All the others are great. I'm sorry for the bad review, but $26 is a lot, so I think I should like it🤷♂️

Only protein drink I've found that I like!
These Protein2O Cotton Candy drinks are amazing! The only protein drink and flavor that I've found that I can drink. I have an eating disorder called ARFID and I have a real problem with funky textures. All those shake type drinks make me gag. I tried the strawberry/watermelon flavor of this brand, but it has a funky sour taste. Due to ARFID, I have a really hard time getting nutrients in my diet, especially, protein. Please Protein2O, don't change this product or stop making it. Love it!
