1st off the taste of these is phenomenal. In my opinion, when used in conjunction with a Soda Stream it tastes just like the real thing. And I usually think anything diet tastes awful. My water intake increased dramatically using this product. BUT I also noticed I started craving sugar in a way that I never have before. I don't like sweets, but one night I ordered $90 worth of junk because I was craving everything from candy to cookies. I've never done that before. I really do NOT like sweets at all. I decided to cut out these additives and after 2 weeks the insane sugar cravings disappeared. Maybe it's a placebo, but I'm choosing to believe it is not. They also all contain either Red 40, Blue 1, or Yellow 6. Here's an excerpt from a study published by the National Library of Medicine specifically on those dyes: "Conclusions: This review finds that all of the nine currently US-approved dyes raise health concerns of varying degrees. Red 3 causes cancer in animals, and there is evidence that several other dyes also are carcinogenic. Three dyes (Red 40, Yellow 5, and Yellow 6) have been found to be contaminated with benzidine or other carcinogens. At least four dyes (Blue 1, Red 40, Yellow 5, and Yellow 6) cause hypersensitivity reactions. Numerous microbiological and rodent studies of Yellow 5 were positive for genotoxicity. Toxicity tests on two dyes (Citrus Red 2 and Orange B) also suggest safety concerns, but Citrus Red 2 is used at low levels and only on some Florida oranges and Orange B has not been used for several years. The inadequacy of much of the testing and the evidence for carcinogenicity, genotoxicity, and hypersensitivity, coupled with the fact that dyes do not improve the safety or nutritional quality of foods, indicates that all of the currently used dyes should be removed from the food supply and replaced, if at all, by safer colorings. It is recommended that regulatory authorities require better and independent toxicity testing, exercise greater caution regarding continued approval of these dyes, and in the future approve only well-tested, safe dyes." So decide for yourself if it's worth it. It's not for me. Read more

Great taste! I fizz up water in the soda stream and toss in a couple squirts of any of these flavors and it’s just like having that real soda with less sugar and calories! Great value for the money Read more

I’m trying to cut down on my son’s sugar intake. He won’t drink water and only drinks sugary drinks like fruit punch and lemonade. So I bought these where I can fill up a huge jug with water and add a little squirt of these flavors and it worked! He’s now drinking a TON more water and a lot less sugar! Read more

There are a lot of water 'enhancer' drops here on Amazon. I ordered this product becasue it had thousands of reviews. My personal opinion on this product is: It has a chemical after taste to it. Yes, it's sugar free but whatever sugar substitute they are using leave a noticeable after taste in my mouth. The grape flavor a bearable but I'll be looking for another product and will not ever order this again. Read more
