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!

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.

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!

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 stuff works great! It has a slight...off flavor. Kind of like how a caffeine pill or advice tastes. Medical taste is guess? But it's not too over powering considering how well it works. I poor it in my sparkling water often in the morning when I don't feel like making coffee

So my as-is rating for this would be a one as there is in fact an extremely bitter taste, however, I figured out that adding just a little under a teaspoon of light corn syrup to entire bottle eliminates the taste, making it a 5 star product.For years I've started my day with a little bit of VPX Redline in a tall glass of flavored water, both had zero sugar & calories. When VPX was discontinued I was at a loss and tried many different things. At first I thought this was another disappointment but as I don't mind a little sugar in my drink I tried adding a drop of corn syrup to a glass and it made all the difference. Now that I've mixed in about a teaspoon full in the whole bottle, it's super easy to just mix with my flavored water, and I once again have the sweet tart taste I crave. The caffeine itself is great, no shakiness or huge crash. Very mellow but you know it's there. The price really can't be beat.

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.

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