vuka-functional-drinksAnother day, another player in the functional beverage market, right?  Nah,Vuka has a cool name meaning “wake up” in Zulu.  And oh, this one is directly aimed at the older, more sophisticated demographic who doesn’t want to be seen drinking a kidded-up can of youth rage.

One more thing, they’re probably going to succeed.  Come to think about it, Vuka Functional Drinks are another unique and promising entry to the Caffeine Informer blog, you’re invited to read on.


Vuka offers 4 flavors as follows:  berry lemonade (“Workout”), orange (“Awaken”), pomegranate lychee (“Think”), and mango peach (“Renew”).  The truth of the matter is that Awaken is an instant hit in my book, while the rest are simply unique in their own little way.

Awaken’s orange flavor is meant to stand in for nature’s boring version of a morning drink, and it tastes phenomenal.  It puts orange juice to shame and blows Rumba’s attempt at this out of the water.  It’s one of the few drinks out there that forced an involuntary “wow” out of me immediately following the first swallow.

The next best flavor in this writer’s eyes is the mango peach found in Renew.  The first taste analogy that came to my mind was those gummy ring peach candies.  Mango and peach tag-team to deliver a fruity assault on your taste buds, and it’s well done (if that’s your kind of thing).

Workout and Think’s flavors are both overshadowed by their more talented siblings.  Nothing about their flavors really stood out, except that they are both undeniably unique.


Each Vuka drink is rooted in 160mg of caffeine and about 600% combined B vitamin values.  On top of that, Awake adds in some morning vitamins (A, E, C), Workout sports Roobios and potassium, Think includes Gingko Biloba and DMAE Bitartrate, and Renew tosses in some Panax Ginsenge and D-Ribose.  Those are actually just some highlights, hit up their website for the full lists.


Being functional beverages, I attempted to consume each of them at the right time, my perceived results are as follows:

  • Awake: Offers a light, smooth transition from morning sluggishness to afternoon readiness.
  • Renew: I felt a slight twinge of energy, but “renewed” is not a word that crossed my mind.
  • Think: This one actually tweaked me pretty good.  Much like Neuro’s thinking drink, Neurosonic, it was almost too strong for me to keep my thoughts in a straight line.
  • Workout: Who knows if it worked or not.  I don’t lift weights, and I’m not going to down the whole can before I go out on my run.  So I took it in the evening, and it felt like Renew.


So this functional line-up is not perfect, but you know what?  The same goes for the rest of the functional beverages out there.  Nobody’s got it right yet.  Vuka, however, has come close enough to make it easy for me to honestly recommend you try them if you get a chance.  Individual results always vary.

Oh one more thing: I read up on the materials Vuka sent me with the samples.  The group behind the beverages has one of the tightest focuses I’ve ever seen coupled with an ambitious drive.  Based on this and my personal experience with the drinks, Vuka has one bright future ahead.
