NuunEnergy Electrolyte Tablets with Ginseng, Caffeine from Green Tea Extract, Vitamin B12, B6, B5, Magnesium & 4 Other Electrolytes, Gluten Free & Vegan, Mixed Flavors, 4 Pack (40 Servings Total)

I like these a lot bc we had been using Mio for so long which not only contains food coloring which I HATE, but they say one squirt is one serving, but what is the definition of how long a squirt is? I was fed up with the product and was searching for something better and found Nuun. It has more B vitamins than Mio and no added food coloring that is unnatural. Also, each tablet is one serving which is easy. The taste is not as strong but i actually like that compared to the super strong taste of Mio. It takes a few minutes to dissolve but I don't mind bc it's a better product. Overall I really like these!

These have sodium carbonate in them which does make them fizz and I only use them in 2oz to 4oz of water. I can drink a bottle of water on my own time so it doesn't matter to me to shove it into my entire bottle of water and sip on it. The taste is more concentrated with less water. My whole point of using it is to get to the point of what it's for and that's energy. I don't usually respond well to coffee. It makes me tired and I don't want to drink enough tea to get the energy from it. I just want a quick source of energy and this form of energy works for my body. It may not work for everybody, but for me this is something that I've used and I can count on. They're convenient and easy. You can travel with them, you take them to a friend's house and just add to water. No concerns about what a local store may offer or what your friends may have available. I've done this numerous times because I know I can count on the energy source I get from these. If I'm really looking for a boost, I will combine 2 tablets in 4 oz. of water for the equivalent of 160 mg of Organic Green tea leaf extract (caffeine) and 204mg Organic Panax ginseng root extract.. opposed to the 80mg (caffeine) and 102mg (Panax) each tablet has. Some of the complaints are the taste but I'm one of those that if the purpose is met (energy) then I don't care. To me the taste isn't horrible. Hope this helps.

I've been looking for a less expensive alternative to another rehydration product. Nuun Energy came in at half the price so I thought I'd give it a try. The packaging is very functional tubes which are easy to transport.THE PRODUCT: These are rather large tablets that are meant to dissolve in a bottle of water. HOWEVER the tablets should be redesigned to actually fit through the neck of the bottle. As they stand, you must break the tablet in half to fit in the bottle.Once in the bottle, do not expect the product to dissolve immediately. After vigorous shaking, the pieces of the tablet remained intact. After 5-10 minutes they dissolved.THE TASTE: I dissolved the tablet in standard water bottle (500mL). The taste was tart, not sweet, with a slight effervescence. Not that much flavor, but palatable.PERFORMANCE: I took the product at 7pm, which is kind of late for a caffeinated product. My bad. Overall the caffeine "lift" was effective for a few hours with little jitters. I did have issues sleeping that night, so I could tell that it was working. Again, taking it late in the day was my mistake, so I can attest that it was "stimulating" and effective in that regards. From an electrolyte standpoint, I experienced none of the leg cramps that I normally get in the overnights so, while not a scientific study, the product seemed effective there too.FINAL THOUGHTS: While the taste left something to be desired, and the tablets didn't fit into the neck of the water bottle, I found that the Naan energy product delivered, as promised, and would recommend as a coffee or "energy drink" alternative.

Please read! I used to drink energy drinks daily and have looked for so long for a healthy alternative to them. I found these Nuun energy tablets not really knowing what to expect, but surprisingly fell in love with them. I prefer 2 tablets in a 16oz water bottle instead of 1, but that's just personal preference. The flavors are light, crisp, and honestly great. These have pretty much completely replaced energy drinks for me and I love that they don't have any harmful ingredients or additives.

This 4 pack is good to last, as it gives you a variety of flavors to not get bored with. This is my favorite drop in tablet, as the sugar content is much lower than the leading brands and the flavor is a hint and not overwhelming.

I usually order Zip FIzz, https://www.amazon.com/dp/B06W9HP7C1. However, this last time, I decided to add these to my order just to try them out. If all you are looking for is electrolytes and caffeine, this might be right for you. It wasn't right for me.FLAVOR:When mixed according to directions, the flavor us barely discernable (in fact, it would be better if there were no flavor. The caffeine shines through with a distinct bitter taste overshadowing the faint vaguely fruity taste advertised on the package.CONVENIENCE:Don't add the tablets to cold water unless you are prepared to spend 4 or 5 minutes waiting for them to dissolve. I suggest you use a few ounces of hot water, then pour it over ice after the tablet dissolves. That seems to work better.OVERALLIn my own opinion, these are pretty average. there are a lot of very similar products in the market and there is nothing that stands out about these. On the other hand, I'm pretty sure many will find that these are perfect for their needs. They just weren't all that interesting or impressive to me.

Best tasting of them all! Suggested by my cardiologist, this has dramatically lessened my Tachycardia episodes!
