The directions are in English, but they're too small for me to read. Whatever, put some ice in a glass, add the packet, then pour water on it. That's what I did and it worked fine. The taste was a little off, but that's expected with a mix over brewed tea. It had a bit of fizz to it, which was not expected but I liked it. I think it has caffeine added, and it's not bad, but I don't think this will be my new go-to drink or anything. The slightly off flavor of the instant tea mix is just not my new thing. Read more

These TEAZEN Energy Tea packets make it easy to make a bottle of flavored water out in the field. I ended up using larger sport bottles (18 ounces of water/ice) and I still find one packet gives the drink enough sweetness for my palate. I like the overall flavor and does give me a little bit of an energy burst. Convenient way to up your hydration level. Read more

These make a tasty and refreshing tea with a subtle mango flavor. They mix really well with water, it doesn't take much stirring to get the powder to completely dissolve, leaving no sediment in the bottom of the glass. I did not notice any energy boost, but it also did not increase my heart rate, like some energy drinks do. I personally really like the taste, but at more than a dollar per serving, I don't know that I would get it again, unless it went on sale. Read more

I can’t say I really felt any energy boost from this, but I mean, I also don’t feel any from several shots of espresso. So, I can’t speak to that. I did notice that I didn’t have the usual afternoon slump, but I was also working on fighting some invasive plants so I may not have noticed that either. My main reason for grabbing this was the mango and guava picture on the front, aka some of my favorite flavors! Plus, I tend to like a lot of Korean stuff. Admittedly, I can’t read without a translation so I did miss that this has a bit of carbonation in it. I really ended up liking that extra little bubbly bit. The flavor was a little mild, but I could definitely taste mango. Not so much on the guava, but okay. It wasn’t too sweet at all, despite containing sucralose, which I do find often when used as a sugar substitute can get super sweet and cloying fast. It was just a good, kind of refreshing fruit tea flavor. As far as the powder itself goes, it dissolved in cold water very easily and quickly for me, and the individual stick also did a good job at ripping easily to be able to pour the water in. Overall, I would recommend these, though for me it might be better to just make a large batch of fruit tea myself since I didn’t really notice any energy boost. They are nice for being on the go though, since they do come in individual sticks. Read more

This is a very nice energizing drink in a package with 10 potable sticks. It contains a brown powder with a fruity smell of mango flavor. It is very easy to make a nice cup of tea with a lot of caffeine and a strong delicious mango flavor. Everything is dissolved to give you a clear tea with a lot of foams on top. The color and some of the caffeine come from black tea. Extra caffeine comes from Guarana extract. Besides the immediate energy boosting from caffeine, this product also contains taurine and L-carnitine. These agents are nice amino acids that would work together to help improve performance and reduce fatigue by boosting health of brain and heart. Read more
