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!

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.

This product definitely gives a boost to any drink I make and helps me save money on energy drinks throughout the week. My only critique is that it adds a slightly unpleasant taste to my beverages. If you could improve the flavor, I would easily rate this product 5 stars!

Very good value for a caffeine addictive. The travel vial is very nice. Dosing on the bottle is easy to do. The strength is 90mg per serving, close to a strong coffee. Has zero taste that I can tell, and can be added to most anything. I've put it in tea, water, Gatorade, and a smoothie. Goes well with water flavorings also.

Just received my 3rd bottle of this and still love it. I add it to apple juice, herbal tea, pineapple juice, lemonade, smoothies, etc.The taste is bitter but minimal and easily masked by adding it to flavorful stuff. In my opinion, regular coffee is more bitter than this product.I keep the bottle refrigerated after opening and it lasts me for a little over 2 months.

I works enough to get you what you need. It's pretty effective, but it taste AWFUL! Makes every drink I put it in taste really bad. It's hard to get it down. Now it works FAST though! Like Lightening McQueen FAST.

Nice source of caffeine if you don't want to drink coffee. Does have a little after taste but it's not that bad

I've been using this liquid caffeine for several years it's a great pick me up whenever I need it, it doesn't make me feel jittery and there's no 'crash' after. You really can put in anything you drink.
