Even though water is essential for all functions of the body, slurping the proper amount of fluid ounces per day may feel like a full-time job; but the consequences of under-hydrating are immense. Registered dietitian Callie Exas, MPH, MS, RDN advises that as little as a 2% loss in hydration can negatively impact cognition, memory, mood, and reaction time. And if dehydration persists, it can increase the risk for heat illnesses like heat cramps, heat exhaustion, and heat stroke.
The best water flavorings can make drinking fluids more enjoyable, especially for those who tire of drinking plain water but still want to stay properly hydrated. To find the top water flavorings, we tested dozens of options, paying close attention to flavor, texture, aftertaste, smell, and value. We also tapped dietitians to help us evaluate each options’ ingredients list and only chose ones that are actually good for your body.

Who It’s For
Best for those who want an affordable, simple boost to their water routine that adds electrolytes, mixes effortlessly, and doesn’t break the bank.
Why We Love It
If you want a water flavoring that leaves no trace when mixed, gives you extra electrolytes, and offers the most bang for your buck, look no further than Clear Theory Water Booster. As newbies to the water flavoring game, we were blown away by this booster that mixes with ease, leaving no clumps or unevenness (unlike the tablets and powders we’d used in the past). In fact, we found that we didn’t even have to stir it in order for the liquid to be completely dispersed in our water.
We were also impressed with the taste. There was no aftertaste at all, and the flavor was remarkably true to its promise—we tried watermelon-berry, and that’s exactly what it smelled and tasted like. The fact that this water booster includes all-important electrolytes and is reasonably priced makes Clear Theory Water Booster our top choice for best water flavorings, and we’d happily recommend it.
Potential Flaws
- The plastic bottle packaging is attractive and functional but likely won’t be properly recycled, raising environmental concerns.
- While this water enhancer contains electrolytes, the exact amount isn’t clear.
Most Valuable Insight
“I’m more accustomed to tablets, which often clump and leave residue—in contrast, this liquid format mixed cleanly and instantly, making it a great alternative I’d consider using regularly.” —Ray Y. Verywell Fit product tester

Who It’s For
Best for people looking to add flavor without sugar or a hefty price tag.
Why We Love It
If you’re looking for an affordable flavoring to add to your water, Lakanto Sugar Free Water Enhancers might be for you. True to its name, there’s no added sugar in this mix, and the liquid formula mixes easily with water, leaving no clumps or grit behind.
Our experiences with water flavorings in the past left us looking for ease of use when it comes to adding flavor, and this pre-mixed liquid fit the bill—one teaspoon, stirred well, was enough to produce a pleasant and light fruity flavor that made it easier for us to increase our hydration and overall liquid consumption. The final result after mixing this flavoring was a smooth drink with no visible separation. And for the price tag, this product can’t be beat.
Potential Flaws
- It was hard to determine the recommended 1 teaspoon serving without a measuring spoon.
- While this was easily mixed into water, we did notice a slight residue left behind in the glass.
Most Valuable Insight
“The final drink was smooth, and there was no visible separation while drinking. It mixed very easily into the water with just a bit of stirring and didn’t leave any clumps or grit, which made it pleasant to drink..” —Amy K. Verywell Fit product tester

Who It’s For
Best for adding flavor without calories or sugar, so you don’t have to compromise on taste or health.
Why We Love It
Looking to replace your soda or juice with something just as flavorful but sugar-free? Look no further than Pure Inventions. Not only were we fans of the strong watermelon flavor, but this water booster also delivers electrolytes and Vitamin C, so you get a punch of health alongside your punch of flavor.
Compared to the electrolyte tablets we normally use, this water flavoring mixes instantly with no stirring required, and no clumps, grit, or residue left behind. We also loved that the dropper included with the bottle (and a glass bottle at that, which is recyclable) made it super easy to measure how much we were adding to our water. In fact, while the company recommends one to two dropper-fuls of liquid, we found that one was plenty, which made this little bottle go a long way—especially important considering it’s on the pricier side.
Potential Flaws
- Testers did notice a fake watermelon aftertaste (described to be like watermelon-flavored bubble gum), but it dissipated quickly.
- In terms of cost, this product is at the higher end of the spectrum compared to others.
Most Valuable Insight
“This product mixed instantly—no shaking, no stirring, no clumps, no grit, no residue; the drink was consistently smooth.” —Ray Y., Verywell Fit product tester

Calories: 5 calories | Sweetener Type: Stevia leaf extract | Sugar per Serving: 0 grams | Organic: No | Non-GMO: No | Form: Cubes | Our Overall Rating: 4.6/5
Who It’s For
Best for those looking to add electrolytes to their daily water consumption to boost energy and performance.
Why We Love It
If you’re an active, on-the-go type person who needs to constantly replenish your electrolytes, Waterdrop Microdrink is for you. This flavor boost comes in the form of dissolving cubes, which are individually wrapped, making them convenient for someone on the move who’s looking for a grab-and-go solution to adding flavor to their water. Throw a cube or two in your gym bag and don’t think twice.
These cubes fizz in still or sparkling water with no mixing or stirring required—just drop it, leave it, and enjoy it. We particularly liked the scent of this water flavoring, which smelled fruity and very sweet; however, the actual taste was surprisingly salty (reminding us of its electrolytes). But despite this unexpected contrast, we didn’t find the taste unpleasant at all. And with many cubes to a box, this product is sure to last you a while.
Potential Flaws
- Takes up to 10 minutes to dissolve fully, and once dissolved, the cube leaves behind some gritty sediment.
- While not a total dealbreaker, it was surprising that the flavor of the drink (which was slightly salty) didn’t match its sweet aroma.
Most Valuable Insight
“The cubes are tiny and are each individually wrapped. It makes it convenient to grab and go, and the packaging makes it sanitary. Plus, the scent is strong enough to lure you in to hydrate more.” —Amy K. Verywell Fit product tester

Who It’s For
Best for folks who want to jazz up their water with no calories and vibrant colors.
Why We Love It
These tiny squeeze bottles add vibrant colors to your water, making hydration more enjoyable. Plus, we love that the easily mixable colors can be achieved without the use of any food dyes and with zero calories and sugar per serving. These water flavorings come in a variety of flavors, including Strawberry Watermelon, Lemonade, and Blue + Blackberry.
According to customer reviews, the flavor is a bit faint, making it tempting to increase the dose. However, we appreciate that the flavors still taste as advertised and are made with real fruit and vegetable juices and no artificial ingredients. Some flavors also contain additional ingredients for added benefits, like potassium and vitamin C.
Potential Flaws
- The flavor in the recommended dose is a bit faint.

Who It’s For
Best for energy drink lovers who want the taste without the caffeine.
Why We Love It
Popular energy drink brand Celsius has developed a hydrating water flavoring without the caffeine of its original beverages. This low-calorie, zero-sugar, and dye-free powder also contains 210 milligrams of sodium and 700 milligrams of potassium, which is comparable to the typical electrolyte content in traditional sports drinks, but without the added stimulants.
The flavor is prominent, bordering on strong, and actually tastes like what’s advertised. Flavors include Blue Razz, Lemon Lime, Strawberry Watermelon, Fruit Bunch, and Arctic Cherry.
Potential Flaws
- The sodium content may be too high for some.
- The product also contains moderate doses of B vitamins, which might make you exceed your daily dose if you’re already taking a vitamin B supplement.
Key Specs
Calories: 15 calories | Sweetener Type: Coconut sugar and Monk fruit | Sugar per Serving: 2 grams (0 grams added sugar) | Organic: Yes | Non-GMO: Yes | Form: Powder
Who It’s For
Best for those seeking an organic product with a simple ingredient list.
Why We Love It
Sol-ti offers a unique blend of ingredients to boost your water. This small dose of powder is made from a blend of organic plant-based ingredients, including dried coconut water and organic fruit.
Flavored with monk fruit and a touch of coconut sugar, this powder certainly has an earthy element. The four flavors each contain slightly different functional ingredients aimed to benefit the skin, digestion, and immune system.
Potential Flaws
- Customers say this water flavoring is a little difficult to mix. We suggest using a milk frother or whisk to thoroughly incorporate the powder.
- While the product promotes its electrolyte content, it contains very little.
Water Flavorings We Also Tested
We tested eight water flavorings and enhancers, but only a small group made it to our final list of recommendations. The following products earned some honorable mentions; however, they ultimately didn’t meet our rigorous testing requirements.
- Buoy Energy Drops mix instantly and cleanly without residue or artificial aftertaste, making them ideal for those who dislike sweet or artificial additives. However, this product lacks clear dosing guidelines and is expensive for the value it provides unless you have very specific needs.
- Cirkul’s Starter Kit is a convenient all-in-one system that requires no mixing or stirring and offers user-controlled flavor strength. However, our testers found it to be overly sweet, with a lingering chemical aftertaste, and an environmentally wasteful design.
- Gatorade Propel Powder is a budget-friendly, familiar, and trusted brand, but the Propel powder fell short due to its gritty texture, overly sweet artificial flavor, and noticeable residue, which made the drink unappealing.
- Magna Magnesium Powered Electrolytes provide a traditional electrolyte flavor experience with added magnesium and a strong hydration focus. But it requires lots of stirring, leaves a mild residue in the bottle, and has an intense flavor that may be too strong for some.
What We’ve Updated
- Since publishing our initial list of the best water flavorings, we tested eight options ourselves, following our rigorous testing guidelines and dietitian recommendations.
- We spoke to a fourth dietitian, Eliza Savage, MS, RD, CDN, who provided guidance on nutritional quality and ingredient integrity of the products we recommend.
- We reworked our superlatives based on reader interest, adding new categories like best organic, best packets, and best zero-calorie.
What to Look for When Shopping for Water Flavorings
- Types of Water Flavorings: Water flavorings come in powdered, tablet, or liquid form. If you prefer to add flavoring to your water on the go, you may want to consider the easy-to-carry, single-serving products, which are generally found as powders and sometimes drops. There are also pre-bottled or canned flavored water options that do not require mixing.
- Electrolytes: Electrolytes help to maintain adequate fluid balance in the body. For most healthy individuals, eating a balanced diet and drinking enough water is sufficient to replenish electrolytes, but you may need more water and electrolytes when you’re exercising, ill, or traveling. In these cases, opting for a water flavoring with added electrolytes can be beneficial, as an electrolyte imbalance can result in a host of adverse effects on the body.
- Caffeine: There is often a concern about caffeine having a strong diuretic effect, but truthfully, moderate caffeine consumption (up to 400 milligrams a day) has been found to only have a minor, short-term effect. Choosing a water flavoring with caffeine is a personal preference, so consider how caffeine makes you feel. Some find caffeine gives them a helpful, added energy boost, while others can feel jittery and experience gastrointestinal discomfort, depending on the individual and the dosage.
- Sweeteners and Flavorings: It may be hard to drink enough water if you are used to drinking soda or juice, which tastes a lot sweeter. However, many of our picks provide plenty of flavor while leaving out excess sugar. Non-nutritive sweeteners like sugar alcohols, monk fruit, and stevia—deemed safe when used in moderation—are other ways to provide sweetness, but not everyone tolerates them well.
How We Tested the Water Flavorings
After narrowing down dozens of water flavorings to eight dietitian-approved options, we tested each one following a consistent rubric and paying close attention to aroma, taste, and texture, along with the ingredients list. When evaluating for each criterion, we focus on these key factors:
- Texture: Water should be a smooth experience. We tested each product to see how easily the water flavoring was incorporated into the mix and left it to settle to evaluate for clumping, separation and residue. Water flavorings that received a high texture score seamlessly blended in with our H2O.
- Aftertaste: Alternative sweeteners, flavorings and other common ingredients can all contribute to a lingering aftertaste. After tasting each water flavoring, we evaluated whether any artificial flavor notes were present and, if so, noted how long they took to dissipate.
- Smell and Taste: Smell impacts taste! When tasting each water flavoring, we noted whether the smell and taste aligned with its advertised flavor. Flavorings that received high scores for smell and taste won’t leave you expecting one thing and getting another.
- Value: We looked at total price and crunched the numbers on cost per serving to disclose costs and share the best value water flavorings.
- Ingredients List: We consulted with dietitians to evaluate the ingredient lists of each water flavoring we tested. We prioritized options with natural or no sweeteners and without food dyes. We also favored options with 20 or fewer calories per serving.

Frequently Asked Questions
Is it okay to drink flavored water every day?
Plain water should still make up the majority of your daily water intake but adding some doses of flavor along the way is a great way to stick to your hydration routine. Try alternating between plain and flavored each time you refill your water bottle.
What’s the healthiest flavoring to add to water?
If you want to add some flavor to your water with the simplest ingredient list consider adding fresh fruit, vegetables or herbs. Melon, berries, citrus, cucumber or fresh mint are just a few of the ways you can infuse water with flavor that is free of additives and calories. If you want to opt for a store-bought water flavoring, Clear Theory Water Booster is our top choice.
Can you drink flavored water if you have diabetes?
Being well-hydrated is an overlooked aspect of diabetes management. Water is very helpful for overall blood sugar balance. When using a flavoring, opt for products that use natural, sugar-free fruit flavorings or contain alternative sweeteners that are shown to have little to no glycemic impact, such as stevia, monk fruit, or sugar alcohols (allulose or erythritol, for example).
Does flavored water hydrate you?
Yes, the base of flavored water is still water, so the science of hydration theoretically works the same whether you are drinking plain tap water or you decided to start drinking water with added flavor. For certain groups of people, such as endurance athletes or people who find that they sweat heavily, drinking flavored water with added carbohydrates and electrolytes, like sodium and potassium, may further improve hydration.
