There is an all natural Flavored powder drink mix called Stevita.
It is like powder Gatorade. They have a few flavors. You just mix with water.
It is just natural flavored "Stevia" which is a plant. I love it. I have even mixed it up like a drink but made natural jello. I don't like artificial colorings either.
There is also a natural "diet" soft drink called "Zevia" It is sweetened with Stevia as well. I love the lemon lime, and the cola.
Here are the websites to check them out.

Hope this helps.
