I got the Tropical Punch flavor and it was really good. It’s not chalky or choke you like others on the market. It is recommended to mix in 16-34oz. I found it to be too sweet when mixed in a 16oz bottle of water. I did have to use a shaker bottle and mixed it in 20oz. I didn’t get the jitters. I felt more alert and awake.

I really liked the idea of no sugar or calories which was the main reason I tried these. The convenience of the individual packets is great so you can have them with you wherever you go. I almost always have a bottle or travel cup of water with me and it’s nice to be able to add flavoring sometimes especially with the added benefits this product provides. I definitely felt more energy without any jitters like you might get from a regular energy drink. I would use these again however I would choose a different flavor as I found the Tropical Punch a bit too sweet for me. I also think it would be nice if you could purchase a box that had a variety of flavors especially the first time you try them.

Great alternative to constantly picking up energy drinks on the go. Drinking one in the morning to get the day started or even before the gym is the routine I see these will work best for. Doesn’t taste to artificial but still has a bit of that after taste in your mouth. The added vitamins, electrolytes and other benefits definitely make this a great energy source!

4D is a simple, tasty, and effective way to recover from a workout or prepare for exertion! It is a flavorful powder that is diluted in 16 ounces of water. It is packed with vitamins and minerals, but also dairy, gluten, soy and GMO free. It is also vegan and keto friendly. I thought the taste was refreshing and I was impressed it contained 10 vitamins, minerals, yet no calories! I did feel a boost after drinking it! The only downside I see is that it contains sucralose ( to be sugar free) and some people are sensitive to this sugar substitute. Overall I would recommend this product!

I enjoyed this product. We got a refreshing nicely flavored drink that was easily used while traveling. Open the packet, pour it in the container, shake it and drink. It provided a nice energy boost. My wife had cold like symptoms which seemed to have a shortened duration as well.

Not a fan of tropical punch but I actually liked this because it reminds me of the kids Flintstones Vitamins! Taste is good and I did get a great boost of energy. Only suggestion is the packaging, maybe increase the add to water font bigger so customers know it's a drink supplement... it'll get lost in the millions of other supplements on the shelves.

This is a great drink. Very flavorful, not gritty at all. It mixes very well without a shaker or blender, just by hand. It has no aftertaste. It definitely provided more energy, we are using it to give us an afternoon boost during our long work days.

The flavor is drinkable, too sweet for me, but with extra water helps. The down side is you can really taste that fake sugar. I did feel like it gave me a boost everyday that I did have a mix and it helped with my water intake. I'd say, definitely give it a try.

So I tried it two different times in normal size water bottle . Each time it gave me a bit of heartburn . The taste was good even though it was a little tart at the end. Couldn’t really tell a difference in energy. Did make me feel a little funny. Wish I had a better review to give but I won’t be trying it again.

I like the tropical punch taste, although I do prefer a stronger flavor. While I am somewhat sensitive to caffeine and this is too much caffeine for me I used a little more water to mix in, which is also the reason I believe it wasn’t as flavorful. I hope Sam’s eventually carries other flavors or at least the multi flavor pack in the future.
