Product Information



Mother Nature's best weapons against stress, in a sugar-free powdered drink mix.

StressKiller® features a proprietary blend of powerful stress-fighting nutrients, including:
  • Tyrosine, which "significantly decreases symptoms" of stress, according to military research.
  • Theanine, which “relaxes the mind without inducing drowsiness," according to clinical nutrition findings.
  • Magnesium, which can help “prevent common stress symptoms,” according to a leading national medical clinic.
  • Vitamins B6, B9, and B12 -- because "B12 and other B vitamins play a role in producing brain chemicals that affect mood and other brain functions,” according to one of the country's leading medical institutions.

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!

StressKiller is Amazing!!!
StressKiller has allowed me to have 3 part time jobs, and go to school for computer engineering, without having a mental breakdown. This product is incredible and tastes fantastic!

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!
