Brain Supplement | Concentration, L-Theanine, 30 Drink Packets

I was very pleased with how good this tasted. Even though it is sweetened in part with Stevia leaf extract, it doesn't really have that unpleasant Stevia taste to it. I also appreciate that the list of ingredients is simple and to the point, not using a ton a random fillers.In water, the powder dissolves quickly and nearly completely, leaving almost no residue in the bottom of the glass. The individual packets are convenient, so no measuring spoon required. My biggest issue is cost, as these are not particularly value priced at $2 per serving (as of this writing). That seems a bit high to me and will likely keep me from purchasing this in the future, which is too bad since this is one of the best flavored powdered drink mixes I've tried.

These have a great flavor! In fact as soon as you open the bag you can smell how good this is going to taste. These are super convenient to pack in your gym bag and really easy to mix into your water bottle. I 100% recommend these portable drink mixes!

I definitely need help with concentration and focus. Package suggests taking this after lunch - I was worried it would affect my sleep but it didn't. In fact, my Fitbit indicated an increase in heart rate variability (which is good) and a decrease in resting heart rate (also good.) Both of these can be indicators of reduction in stress. Unfortunately I didn't notice an immediate increase in focus or concentration.The taste, however, is not for me. It's way, WAY too sweet. My water bottle is 24 oz and at that dilution it's still much sweeter than I care for. If you're making a smoothie with fruit that's naturally tart, this might be just the thing to balance that out.I'm intrigued by the improvement in my heart metrics, though, so will continue to use to see if I notice cognitive improvement.

Not bad! Mixed up decently in a glass of water, taste was tolerable. Took in the afternoon to help me power through the rest of the day! Was able to fall asleep fine, even when drinking around 2. Good stuff. I enjoyed it!

I really like the flavor of these! They dissolve in water well and don't have a negative after taste. I haven't noticed any negative side effects after drinking these in the morning. I plan to continue using these in place of my usual drink packets and hope for ongoing good results!
