Available in a variety of delicious fruit flavors, Stur water enhancers are the liquid drink mix for consumers looking for natural ingredients. Delicious, naturally flavored water can now be made at home or on the go with our portable liquid drink mix bottles. To use, flip-open the cap. Point downwards directly into your water. And squeeze 1 second per serving in 8-ounces of water (squeeze longer to add more flavor)! Each portable bottle of Stur makes 20 8-ounce drinks with 0 sugar, 0 calories, and 100% Vitamin C per serving. The Stur brand is about helping others to love water naturally. Stur was born while my wife was pregnant with our twin girls. The doctor had recommended she drink 8-10 glasses of water a day. But like most Americans, she wasn't drinking even half of that! So I started looking for healthy ways to flavor her water. I went to the store and searched the drink mixes, but found that they were all made with artificial chemicals that we didn't feel comfortable putting in my wife's body. Finally I asked a food scientist friend to help me create a liquid blend of natural fruit flavors and natural stevia leaf extract to squeeze in water. It took us over a year and hundreds of different formulations to land upon a blend that tasted better than most bottled sugary drinks (and we're still tinkering to perfect it)! I called our special blend "Stur" and proudly wrote on our hand-drawn label that it had 0 calories, 0 sugar, essential vitamins, and NO artificial sweeteners, colors or flavors. (That initial label was hand-drawn by yours truly, and by popular demand, it has since been replaced with a more professional one!). Just like so many others, I hope you love Stur as much as we have put love into making it. If for any reason you aren't satisfied, just let us know --- we will make it right.
