Best Sugar Free Water Flavoring Drops of 2025

"I've found Stur Liquid Water Enhancer to be a game changer! I typically find plain water boring, but this product has made it so much more enjoyable. The flavors are bright and refreshing, and I love that it's sugar-free with natural ingredients. It's also convenient to carry around, making it easy to stay hydrated on the go!"

"I recently tested various flavors of both Stur and Sweet Leaf Water Drops, and I have to say, Stur's Strawberry Watermelon is my absolute favorite. The flavor is sweet and smooth without tasting artificial. I appreciate how the sweetener used doesn't leave a weird aftertaste like some others do. Overall, I think Stur offers a solid variety!"

"While I really enjoy Stur Liquid Water Enhancer, I do think it's a bit pricey. I ended up paying almost $10 a bottle, which included shipping and extra fees. Even though I love the product, the cost might make it hard for me to buy regularly."

"I was searching for a better alternative to grocery store brands and decided to try these. Unfortunately, the flavors were disappointing, with a strange medicinal taste that made them hard to enjoy. I ended up tossing them out after trying each one."

"I use this product often and think it's the best tasting brand I've found. I've enjoyed it so much that I've even spilled water because it tastes so good!"

"Despite some mixed reviews, I bought the 10 pack and found it AMAZING. The flavors are subtle and taste like real fruit, not synthetic at all. I love that it's dye-free and health-conscious!"

“I find it hard to drink plain water, so I flavor it to meet my daily intake. This set has consistently offered the lowest price per ounce for years, making it the best value. Plus, the flavors taste fantastic!”

“I grew up enjoying slushies, and these flavors remind me of them. They taste slightly chemical at first, but you get used to it. I mainly use them for my homemade sodas, and I really enjoy the Icee flavor!”

“Using these is super easy. Each flavor is delicious, and I appreciate being able to choose how strong the flavor is. They help me drink more water daily, and I’m definitely planning to buy more!”

"I've fallen in love with my coffee again! Stevia offers a guilt-free sweetness without the calories. Just remember, it can taste a bit bitter if you add too much, but a little goes a long way. Our 9-year-old enjoys the chocolate flavor in her milk—just like real chocolate milk without the sugar! Switching from honey to this has even helped me lose weight!"

"My husband and I have been loyal customers for three years, enjoying the taste these drops add to our water. However, I was very disappointed with the recent peach mango flavor. It tasted nothing like peach or mango and had a strange, bitter taste. I tried multiple bottles, and they all had the same issue. Customer service was unhelpful, directing me to Amazon instead of addressing the product problem."

"I don’t particularly enjoy plain water, so I was on the lookout for a better-tasting stevia alternative. I appreciate that it’s calorie-free and has no artificial sweeteners. It’s easy to carry, and I find myself drinking much more water now! However, the flavors can vary, and I found some to be less flavorful than expected—especially the lemon-lime, which I wouldn’t buy again."

"I simply need one nice squeeze into my water glass for some really delicious flavor! Plus, I appreciate that it is monk fruit based!"

"I enjoy the flavor, but there's a slight metallic taste that lingers. I've tried adjusting my usage, but that metal flavor remains in the background."

"The Lakanto vanilla is my favorite because I only need a few drops to flavor my drink. However, this one seems to have a much weaker flavor, so I have to use quite a bit to get any taste."

"I really enjoy this product! It makes water less boring and blends instantly. I can easily customize the flavor to what I like."

"I've been using the 4C liquid water enhancers for years now. No more undissolved powder at the bottom of my bottle! I love being able to mix flavors effortlessly."

"I was disappointed from the start. It tasted like plastic smells. I think I’ll stick to Mio or other quality brands."

"I use this flavor for my kids' sports and hydration. It's a light, nice flavor that beats bottled sports drinks because I can control the sweetness and intensity. Plus, this little bottle lasts longer!"

"I really enjoy Mio electrolytes, but ordering can be a hassle. Still, they help keep me hydrated and taste great!"

"I absolutely love Mio! However, I was hoping this flavor would be as strong as the others I've used for years. Unfortunately, this one is quite weak. I find myself using a lot more just to get a decent taste. It’s strange because most other flavors are strong enough that I sometimes need to dilute them. If you prefer weaker flavors, this might work for you, but it doesn't feel worth the cost to me!"

"I absolutely love the flavor of the fruit punch product. It’s so good it’s addictive! I squeeze it into my ice water and enjoy cold drinks without worrying about carbs, sugar, or calories."

"My family and I are obsessed with this water flavor. I avoid sugary drinks, but regular water is just too boring. This flavor is simply delicious!"

"I was looking for a tasty flavoring to help me drink more water without extra sugar or calories. I found the Stur fruit punch and really enjoy the light taste, although I tend to use a little more than recommended for a richer flavor."

"I find that Mio really helps me drink enough water. It's my husband's favorite, and since it's not always available in stores, we order it online to ensure he doesn't run out."

"I think the price is a bit of a rip off. Buying 12 for $59 means each costs $4.91, while I can get them individually here for just $3.15."

"I ordered these because I couldn't find the electrolyte version locally. I really appreciate the price break!"

"I find that it tastes good and quenches my thirst better than just water. Honestly, I like it better than Gatorade!"

"As an avid golfer, I always add a bit of this to my water on hot days. The nice flavor and ability to adjust the amount really provide tremendous value. I often recommend it over Gatorade!"

"I love using Mio to change up the taste of my water. The electrolytes are a big plus for staying hydrated, too!"
