Water enhancers sweetened with stevia are a great way to add satisfying flavor to your water, without adding calories.
What’s more, stevia is a natural sweetener. Excessively sugary beverages like soda or juice are bad for our health, but some research suggests that artificial sweeteners may have negative health effects as well. That’s why many of us have turned to natural stevia for sweetening our beverages.
Stevia is derived from the stevia plant, which is native to South America. It’s been linked to several health benefits, including lower blood sugar and cholesterol levels. It may also aid some people with weight management. Additionally, since stevia doesn’t raise blood sugar levels, it can be a popular choice for diabetics or for those who fast.
Whatever your reason for choosing a stevia water enhancer, it can be difficult to know which ones taste best — especially if you’re shopping online. That’s why our team set out to find the best tasting water flavorings that are sweetened with stevia.
Our highest rated stevia water enhancers were:
- Stur Liquid Water Enhancer: Great fruit flavors
- Sweetleaf Sweet Drops Liquid Stevia Enhancer: Delicious dessert flavors
- Nuun Sport and Nuun Energy Eletrolyte Drink Tablets: Perfect for athletes or caffeine lovers
Criteria for the Best Stevia Water Enhancers
Our team tried five of the most popular water enhancers available online. We had a very specific set of criteria for determining your best options. We believe that a water flavoring product with stevia should meet the following standards:
- Stevia must be the primary sweetener
- Great taste is a must
- Portable and easy to mix with water
- Caffeine, vitamins, or minerals may be included
- May come in tablets, powder or liquid form
Using these criteria, our team of taste-testers recommends the following options for stevia sweetened water enhancers — whether you’re using them for flat or sparkling water.
Stur Liquid Water Enhancer began as the founder’s attempt to help his pregnant wife drink more water. He discovered that most water enhancers contained artificial ingredients that he was not comfortable serving to his family, so he decided to create his own.
A bottle of Stur delivers about 24 servings of flavored water. Made with stevia and real fruit, Stur contains a healthy helping of vitamin C and antioxidants. Offered in a portable flip-top bottle, it’s easy to squeeze as much liquid flavoring as you like into your water.
Stur is available in 12 flavors, and that means it could be difficult to pick just one. That’s why we suggest starting with a variety pack so you can sample a small assortment.
We particularly enjoyed the “Founder’s Favorites,” collection which includes Strawberry Watermelon, Lemonade, Blue and Blackberry, and Fruit Punch. Thankfully, the sweetener aftertaste is minimal, and the flavors are quite robust.
You would enjoy Stur if you are seeking a keto water enhancer that is affordable, easy to use, and highly portable. It tastes great in both flat and sparkling water, adding a delicious splash of stevia-sweetened flavor.
Stur focuses on fresh-tasting, natural fruit flavor. The offerings are refreshing, tropical and perfect for a relaxing afternoon by the pool!
- Blue and Blackberry
- Grape Acai
- Fruit Punch

In 1982, Sweetleaf was the first company to bring stevia to consumers in the United States. For that reason, the brand’s founder is known as the “Father of Stevia.” A family-owned company, Sweetleaf focuses on sustainability and transparency in its products.
Sweetleaf Sweet Drops Liquid Stevia Enhancer is available in sizes ranging from 1.7 to 4 ounce bottles — most of which are glass with a dropper. With zero carbs, zero calories and no artificial ingredients, you can enjoy beverages sweetened with Sweetleaf without guilt.
With over 16 flavors that branch far out from just fruit, Sweetleaf has a lot of enticing options, from pumpkin spice to caramel and chocolate. While they taste great as water enhancers, they’re also ideal for sweetening your morning coffee.
Our reviewers found the dropper bottles to be fun and the flavors highly unique among other brands. Sweetleaf’s stevia is of good quality, so you’re not likely to discern any aftertaste.
If fruity flavors aren’t your thing, Sweetleaf may well be your best option for a stevia water enhancer.
Sweetleaf has a ton of options for flavor – particularly specializing in dessert and fall/winter favorites.
- Clear / Natural (unflavored)
- Chocolate Raspberry
- English Toffee
- Pumpkin Spice

If you plan to take your water enhancer on jogs, hikes, or other adventures, Nuun may be the choice for you. Offered in a portable tablet form, Nuun is packed with electrolytes and contains no artificial flavors or sweeteners. Most electrolyte replacement beverages also contain carbohydrates, while Nuun (pronounced “noon”), does not.
Each plastic tube of Nuun contains ten tablets that will fizz delightfully once plopped into a bottle or glass of water. The containers are perfect for storing in a purse, glovebox, or gym bag. Each tablet is keto-friendly, non-GMO, and contains enough electrolytes to replenish an athlete after an intense workout. What’s more, there’s a caffeinated option – which we adored.
Here’s the catch: Nuun contains just a tiny bit of sugar alongside its stevia leaf extract – about 1-2 grams per serving. This means it may not be the ideal choice for diabetics. According to the company, this small amount of sugar aids athletes in rehydration. Combined with minerals and electrolytes, Nuun promises to assist in recovery and athletic performance.
Our testers loved the Citrus Berry Mix pack, an assortment of four flavors at a reasonable cost – Citrus Fruit, Lemon Lime, Orange and Tri-Berry. We found the fizz to be a refreshing alternative to a flat water enhancement. Aside from working out, we thought it would also provide ideal hydration for recovery from a cold or other illness.
Our Pick for Best Water Enhancer with Stevia and Caffeine
Nuun is also available in a caffeinated variety called Nuun Energy – a convenient way to add caffeine to your water. In addition to the hydration and flavor benefits touted for regular Nuun, it also contains 80mg of organic caffeine and B vitamins.
Nuun Energy had just the right amount of caffeine and stevia to help our reviewers fight that afternoon slump, without consuming the outrageous amount of sugar commonly found in a flavored latte.
When you choose Nuun, you get a variety of citrus and berry forward flavors that are perfect for an invigorating morning gym session.
- Citrus Fruit
- Lemon Lime
- Fruit Punch
- Strawberry Lemonade
Nuun also offers a line of vitamin-enhanced flavors to help supplement your daily nutrition:
