My favorite flavor is Fruit Punch (which ironically is called Men's multi-vitamin boost -- I figure that is just marketing and I drink it anyway). I always loved the taste of fruit punch, and this Zenergize flavor reminds me a lot of the fruit punch I drank as a kid! The Zenergize tablets come in many other flavors and vitamin combinations as well, including but not limited to: berry blend (energy+), tropical punch (energy+), citrus (immunity), orange and pomegranate (thrive), peach and green tea (burn), lemon lime (hydrating), and tropical (chill). Some of the flavors contain caffeine, so make sure you read the label carefully, if you are trying to avoid it.
You can buy Zenergize at Whole Foods (in the vitamin section) or from Amazon (a little cheaper but with a shipping cost).
By the way, for people interested in water substitutes, I wanted to call attention to two previous blog postings I've done on this topic: (1) my favorite sweet tea, and (2) a posting about how to make your own fruity water at home. Having yummy drinks around is really important since sometimes thirst presents itself as hunger.
Enjoy your low calorie flavored water!
