VAULT Caffeine Free Brain Energy Drink – Nootropic for Mental Focus Sharpness Memory and Reaction Time – No Crash or Jitters – Sugar Free – 12 Fl Oz (Pack of 12) – Sour Watermelon + Tart Cherry Flavor

Great for those who don’t want caffeine in their energy drinks

I was excited for this drink because I've been noticing situations where the benefits of drinking it could come in handy in my life. I chose the black cherry flavor because it seemed more palatable than the other options. Upon receiving the 12-pack, I opened it and put three cans in the refrigerator with the intent on drinking one every other day to stretch it out.This is like drinking a liquid Warhead candy. It's so sour that I considered diluting it with water or mixing it with soda. I powered through and didn't mix it with anything, but it was tough to drink, and subsequent cans didn't get much better.By the time I reached the middle of the box, I found that one can had burst open during shipping, and another had completely lost pressure. I tried to get a replacement from Amazon, but was told that this product isn't eligible for refund or replacement. So I contacted Vault. I sent two emails to Vault, informing the company of the problem. Four business days later I had not heard back, so I went back to Amazon and used the chat to obtain a refund.As far as benefits of drinking this, I felt as though I had a slight improvement in mental performance. Some days I felt a boost in energy, other days I didn't. Because this drink is so expensive, I wanted to stretch it out by drinking every other day. Because of this, I was able to compare a Vault day versus a non-Vault day side-by-side several times a week. I lost a little bit of weight, but I've already been controlling my diet, so I'm unsure of whether Vault boosted my weight loss, or if it was just luck.If the flavor could be improved, customer service improved, and benefits could be measured, I would buy a pack of this each month at the very least. But because it's so sour and I couldn't get a representative from the company to respond to my emails in a timely manner, I'm not certain I would purchase this again.Also, doesn't the Coca-Cola company own the trademark for Vault when used for drinks? "Drinks like a soda, kicks like an energy drink. Vault: get to it!" I loved Vault Red Blitz. I miss that drink a lot.

It's marketed as an energy drink, but really this is great for helping you study or stay aware throughout the day. Its more of a focus drink.After drinking one of these I could easily power through a few chapters of the books I've been meaning to read when before I'd have trouble just getting past 10 pages or so before I had to take a break.I've also been having one before work. I drive professionally and work long hours while listening to podcasts. It helped me stay attentive and I could easily focus on 10 hours of podcasts without feeling like I was starting to zone out and not be able to listen.They weren't kidding about it helping you sleep. After a few of these I could feel my sleep patters resetting and I've never had such a restful, deep sleep.It tastes great, if slightly salty.The packaging is my only gripe. It feels like a prototype and occasionally the wrap on labeling will tear near the mouth and poke you in the lips.

This drink is incredibly strong, more than you think. Cut this with water you'll get the same effect. put half the can in a glass add water, the flavor is still there. As for " mental clarity " it didn't do anything, as for energy I don't see any B12 ( naturally occurring vitamin found in red meat & available as a supplement )there's a single vitamin in this drink. Vitamin D for memory thats not enough.Nootropic more like scam!

I was looking for an energy drink without the caffeine as I'm hopelessly addicted to caffeine. These had a very strong cherry flavor and did not have caffeine (or caffeine metabolites like some other "caffeine-free" drinks) as evidenced by my caffeine withdrawals after skipping out on my usual Monster. The energy feeling was pretty good from these, similar to some nootropic supplements. Make them less tart and much cheaper and I'd definitely buy again.

I quit drinking caffeine a about 2 years ago so i was looking for an energy drink to take with me on ling bike rides. This works, but maybe too good though. 5 minutes after drinking i could feel my energy level boosted but my heart rate was just as high as when i drink caffeine. Maybe it would be suitable for me if the can was half the size. If i find it in a small can I'll order again for sure.The taste it very sweet and extremely sour...very reminiscent of Sour Patch Kids candy.

Vault is a product is different than any other product I have tried. It has no caffeine or sugar, but it tastes really good. It's BHB provides hours of energy for me every time I drink it. I survived Colon Cancer but have lymphedema that I manage. I have always been a very health-conscious person, but I definitely upped my game after Cancer and ingredients matter. The BHB also suppresses my appetite, so I end up with more energy and less hunger. No more occasional 5-hour energy drinks or red bull for me with all the sugar. And the price is reasonable when I take into account all the benefits and the costs of similar products. I will definitely be purchasing this again as my son likes it also.

I love this drink, but every month it gets delivered, AT LEAST one of the cans leaks. I'm not sure why, because I can't see any holes. I guess it's the seal? But when it leaks, the cardboard gets soggy, the cans get sticky, and both issues attract dust and make the cans gritty. I end up having to wash the cans before drinking them because who knows what germs get stuck on them. The drink itself does what it's supposed to do, gives energy and mental clarity for a few hours, and it seems good for those who wish to reduce caffeine. But this shipping issue needs to be resolved if I'm going to continue purchasing.
