Verve and Vemma are the real deal. My mother drank Vemma for a long time, the only downside is COST. Honestly, she claims that it improved her lifelong bad eyesight, hahaha. I think thats a bit ridiculous, but the carbonated verve does taste awesome so no complaints when she was buying it for me. The Vemma you take shots of, its a bit nasty tasting but some people give it really high reviews.
Even if it is placebo effect, good reviews are good reviews.
And like I said, that Verve tastes delicious, if ANYTHING its an awesome energy drink/soda replacement. (in my personal opinion, that is to say, it didnt make me feel healthier, but its prob healthier than sugarfreeredbull or soda? idk...)
Good luck selling. We used to just buy directly from vemma...
