To begin with, I do wish they had a version that was a bit more concentrated. I add this to my soda stream sparkling water drinks, and the volume of this I need to make a caffeinated drink sometimes lessens my drinks carbonation. Bubly used to make very concentrated caffeinated drops for the sodastream called "Bubly Bounce," for some terrible reason, they discontinued it. This is a great substitute for that for anyone who loves caffeinated sparkling water like me. I've replaced my morning coffee with caffeinated sparkling water for a couple years now, and I've felt so much better. No more kidney pain or stained teeth. It's amazing to have this for a boost of energy. You can add it to anything because it is truly flavorless. I tasted no bitterness. I love the size and design of the jug. It will last a long time and it's so cool and easy to pour. It shows me the company puts its customers happiness above all. Great product! Would love to see a more concentrated version. Wink. Wink.

I'm a regular coffee drinker for many many years - every day have had multiple cups, probably 2-3 at least in the morning, not in the afternoon. I like my coffee but not the diuretic side effects so much as I've grown older. I've been using this for a little over a week. 15-20mg along with a half a cup of coffee (wife still drinks coffee) or an expresso. Huge improvement and feel like I have a little more energy as well. Also probably could be good for saving money on energy drinks if that is your thing. I combine it with Sparkling ICE water, probably 4 ozs. By itself in water its a little bitter. Built in measurement is kind of nice but I just use a teaspoon which is around 15mg.

I seldom write reviews but I truly enjoy so many things about this product that I feel compelled to share. 1-This product gives me the energy boost that I need to get through the day. Whether my day is packed with brain work, driving, or physical labor, I can count on NuCaffeine to get me past energy hurdles. 2-I love the versatility of this product. I can add it to anything with no impact on the flavor. I love it with my favorite drinks such as beet juice, coconut water, or cucumber water. I have never tried it with plain water, but I am guessing that it would add a slight flavor to it. Adding to its versatility is the ability to add as little or a much caffeine to your drink of choice as you see fit (within good health guidelines). 3- Price point is on target. I usually add about 10ml to my drink after breakfast and again after lunch. One container lasts me about 6 weeks. That is approximately 75-85 energy drinks for around $33. Best deal that I know of. 4- No jitters! No upset stomach! No artificial sweeteners! No added food coloring! Just caffeine from green coffee beans. 5-I do not care for the taste of coffee, nor do I care for coffee breath. These are not issues with NuCaffeine. 6- Last, it comes with a handy little measurement container that easily fits in a purse or backpack. I took it with me on an overseas vacation without a problem I wan not compensated for this glowing review, I just really Ike the product and have been ordering it from Amazon regularly for over two years. Good stuff!

Gives me good energy with no crash. Not super bitter but still very noticeable. I'd recommend adding it to a sweetened drink like a smoothie or juice to mask it. Artificial sweeteners don't cover it up very well unless you use more. Adding it to already caffeinated drinks like coffee, energy drinks, or pre workout makes them taste pretty bad.

This is a money saver, pure liquid caffeine add to anything [ I’ve done it ] and save yourself some money instead of buying espresso shots / 5 hour shots, coffee. Your not supposed to drink this straight, your to mix it in to a beverage. If you follow the directions you shouldn’t have any problems but obviously the one review saying it’s nasty clearly shows they didn’t read the directions. The right side of the bottle has indicators of how much caffeine you can dispense, which is better than guessing. As for the “ To Go “ tube it looks like a container for the male reproductive goo, which I would suggest maybe find a different “To Go “ tube or one or make your own an have a plastics company make it. 94 servings is quite a lot, should last a while. The other reason i buy from this company they don’t use any calcium benzoate which is an ingredient used in foods / drinks to keep it “ fresh “ 😆 which when exposed to heat turns into calcium benzene which is a poison. Buy this an save your money , make your own energy drink/ energy shots. Will buy again :)

I wanted to get off of energy drinks and diet pop, so I bought this. Everyone has a different quantity of taste buds, so what is bitter to one person may not be bitter to another. For me, it’s bitter. I wasn’t able to mask the flavor by mixing it into a drink. Rather, I take a shot when I wake up and another at lunch. The bitterness lasts for a mere moment as I follow it up with sparkling water. I don’t get jittery on this, even though I do from coffee. I do recommend this product. And I will be buying another once it’s gone.

I’ve been using nuCaffeine for a few months now and it’s been a game-changer! Whether I mix it into my morning smoothie, hot tea, water, or juice, it gives me a smooth, consistent energy boost without the jitters I used to get from energy drinks. I’ve found the flavor to be subtle and completely manageable. Plus, the measuring chamber makes it incredibly easy to control my dosage, so I can customize the caffeine level to fit my needs. Overall, nuCaffeine has helped me cut down on expensive energy drinks and coffee runs, saving me both time and money. If you’re looking for a convenient, effective, and customizable caffeine solution, I highly recommend giving it a try!
