This is coconut water. And they're not joking. It's pretty bad. It's salty going in and has the vague hint of baby powder in the aftertaste. I bought this at GNC because the packaging caught my eye and I thought it sounded interesting. It's intended for runners, as it is supposed to offer more immediate hydration than water, but I don't know if putting up with the taste would be worth it. And the lima-citron flavoring only makes things worse. It was like a cheap attempt to mask the very harsh taste of the coconut fluid, and only resulted in adding insult to injury. Unless you are a hardcore runner desperately looking for something for rapid hydration (it was fairly successful on that front), definitely pass this one up.
Verdict: Not recommended
