Great for mental focus & calming nerves (for soccer too)
I use it once a day for mental focus & health (great vitamins & minerals) & twice a day when I'm feeling stressed.
My children take it the 2 days before, and day of, a big test at school.
I have my 2 youth soccer teams take it on big tournament weekends--great for their focus on the field, calming nerves, and it also has a super amount of electrolytes to help them hydrate and recover.

Love the taste and how it makes me feel
I drink a lot of water but often I want something that will give me something more without sugar and articial sweeteners. I drink to soothe me so I can focus better. Stress killer is original and what I have been looking for (without knowing it)!. The color-pink!, the taste--satisfying blend of tart and not too sweet-just right, and the big fizz. Stress Killer meets my needs for a pause in the day that truly takes care of ME! I'll put a few pouches of this with all my gifts.

I really like this product, would recommend it to anyone who has a ton going on in their life. The only downside is there's only one flavor. Really hope they expand and create more great tastes!

Don't let me ever run out!
This product is amazing! There are so many benefits but I noticed the energy that I had after drinking it without the highs and lows. It's an automatic reorder for me!

It works
I tried it and it works! It calms me down, plus it tastes good... it fizzes and tastes sweet with a little tang and a clean aftertaste. Would definitely recommend!
