These definitely quench your thirst but it doesn't last long. Its supposed to be used in sports which is what I intentionally got it for but it got hard quick and lost its flavor but the goal of the product does do what it says just not long lasting. it is pricey though.
I don't know about using them to quench your thirst, since they're gum, but they taste great! They're the right amount of sour to get your taste buds that zing they need to start producing saliva. I really like them as a gum product.
I'm not sure what Quench Gum is all about or what they're quenching...but I know it sure isn't my thirst! The name is quite deceiving and the gum itself tastes great for a whopping 60 seconds. After the gum's flavor dissipates, the consistency of the gum feels like wet cardboard. My advice: if you're thirsty, drink water!!
