I can't find the nutrition information anywhere on the site. The first thing I look for when I see "no sugar added" on any product is the sugar content. Not being able to see that before buying is a no-go for me.

Great point! I will add it to our site.

In terms of our sugar content, is 16g sugar and 17g sugar, respectively. (2 of our flavors are 17g, one is 16g).

In terms of "no sugar added", it's true, we don't add sugar. But we have natural sugars involved - our drinks are made with real fruit which obviously contains sugars. But we don't add stevia, fructose, or anything like that.

Part of hydrating effectively is adding sugar to your bloodstream as well as salts, etc.. in the right balance in addition to water / liquid.
