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!

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!

I needed to kick my energy drink habit due to acid reflux and this has been a fantastic substitute. For me, it tastes flavorless, though I admittedly will add something to my drink (not just water), but even in just water, the taste is extremely faint. It's allowed me to move from soda to fruit-flavored waters or low-cal juice as my drink of choice during the day. I love that I can turn anything into an energy drink. I've been using it for six months now and keep coming back to buy more. 10/10

What a wonderful product! I make my own energy drinks or add it to make a stronger boost of caffeine. No bitterness and highly recommended. Includes a travel size container for your trips. Be careful and don't use too much or you will have the jitters.

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.

Highly recommend! I bought this about a week ago so I could have something to boost me for the gym that didn't break my intermittent fasting. I add 10ml to my water as soon as I get out of bed and it does a fantastic job of waking me up quickly. No jitters, no taste, just clean energy.

My husband and I love this! It gets us away from energy drinks and we can still have our caffeine but in our sugar free drinks.
