Healthy Soda Brands Worth Trying

The soda aisle has been quietly undergoing a revolution. Where rows of high-sugar colas and artificially colored drinks once dominated, a new generation of beverages has taken hold — ones that bring the fizz and flavor but ditch the 39-gram sugar bomb. Whether the goal is gut health or just a better daily drink, these seven brands and categories are changing what it means to crack open something cold.

Poppi – The Prebiotic Soda Built Around Apple Cider Vinegar

Poppi began as Mother Beverage, which founder Allison Ellsworth started selling at a Dallas farmers market in 2016. A 2018 Shark Tank deal led to the rebrand as Poppi, and PepsiCo acquired the brand in 2025 for $1.95 billion. Each 12-ounce can contains apple cider vinegar, cassava root fiber, agave inulin, and real fruit juice, keeping sugar at 5 grams or less. Flavors range from Classic Cola to Cherry Limeade, all with 25–35 calories per can.

The brand markets its formula as gut friendly because of its prebiotic fiber, which is meant to feed beneficial bacteria in the gut, though a can holds only about 2 grams of prebiotic fiber. A 2024 class-action lawsuit challenged whether that is enough fiber to do the gut any real good, and Poppi's maker settled it for $8.9 million in 2025. Many dietitians still see it as a lower-sugar choice than traditional soda. Poppi is Non-GMO verified, gluten-free, and certified kosher, and it's one of the easiest prebiotic sodas to find in stores.

Is Poppi actually good for gut health? Poppi contains prebiotic fiber from agave inulin and cassava root, which feeds beneficial gut bacteria, though registered dietitians note the fiber levels per can may not be high enough to produce a clinically significant gut health benefit on their own.

Where is Poppi sold? Poppi is available at Target, Kroger, Whole Foods Market, Costco, Amazon, and through the Poppi website with direct-to-consumer shipping and flavor subscriptions.

Does Poppi contain caffeine? Some Poppi flavors like Classic Cola contain 40 milligrams of natural caffeine, while fruit-based Poppi flavors are caffeine-free — always check the can.

Olipop – The High-Fiber Botanical Soda

Olipop was created in 2018 by Ben Goodwin and David Lester after years of microbiome research and reformulation. The brand's signature OLISmart blend combines cassava root fiber, acacia fiber, guar fiber, nopal cactus, marshmallow root, calendula flower, and kudzu root into flavors like Vintage Cola, Cream Soda, and Classic Root Beer. Each 12-ounce can delivers 6 to 9 grams of dietary fiber depending on the flavor — up to roughly one-third of most adults' daily recommended intake — at 2–5 grams of sugar and 35–45 calories.

Olipop is one of the most fiber-dense prebiotic sodas on the market, and the inclusion of botanicals like marshmallow root and calendula sets it apart from competitors. The flavor lineup runs deep, with more than 18 varieties. Houston Methodist gastroenterologist Dr. Eamonn Quigley notes that there isn't yet enough evidence to evaluate the claims prebiotic soda makers make, and that like regular soda, these drinks contain added sugar and calories that can add up over several cans a day.

How does Olipop compare to regular soda? A standard 12-ounce Olipop contains 2–5 grams of sugar, while a comparable serving of Coca-Cola contains 39 grams, so Olipop carries roughly an eighth of the sugar or less.

Does Olipop taste like real soda? Most reviewers describe Olipop's cola, root beer, and cream soda flavors as closely resembling their traditional counterparts, though some note a slightly lower carbonation level compared to conventional soda brands.

Is Olipop vegan and gluten-free? Yes — all Olipop flavors are certified gluten-free, vegan, and Non-GMO Project Verified, so they work for vegan and gluten-free diets.

Zevia – The Zero-Calorie Stevia Soda

Zevia has been sweetening drinks with stevia leaf extract since the brand launched in 2007, making it one of the longest-standing better-for-you soda options in the market. All Zevia products are zero-calorie, zero-sugar, gluten-free, vegan, and Non-GMO Project Verified. The beverage portfolio now covers sodas, energy drinks, and organic teas, with 34 flavors across the three lines.

By 2012, Zevia was the best-selling soda at Whole Foods. In 2014 it became the official soda of the Oakland Athletics. A certified B Corp, Zevia also avoids plastic bottles entirely — all products ship in aluminum cans. For anyone managing blood sugar, eating keto, or avoiding aspartame and other synthetic sweeteners, Zevia is the longest-running stevia-sweetened soda on this list.

What sweetener does Zevia use? Zevia is sweetened exclusively with highly purified stevia leaf extract — a plant-derived sweetener with no calories, no carbohydrates, and no artificial ingredients.

Does Zevia have caffeine? Some Zevia soda flavors contain caffeine extracted from coffee beans, while others are caffeine-free — every can is labeled either way.

Does Zevia make a soda for kids? Zevia makes caffeine-free flavors such as Caffeine Free Cola with no sugar or calories, so parents who serve it to children should pick a caffeine-free can and check the label.

Slice – The 1984 Soda Reborn as a Gut-Health Drink

Slice launched in 1984 as a PepsiCo fruit soda brand and faded from shelves in the 2000s before wellness company Suja Life acquired it in 2024 and relaunched it in 2025 as a fully reformulated functional beverage. The new Slice replaces high-fructose corn syrup with organic cane sugar, real fruit juice, and organic stevia, delivering only 35–40 calories and 5 grams of sugar per can. What sets Slice apart from every other brand on this list is its Gutsy Blend — a three-component formula combining 5 grams of soluble vegetable prebiotic fiber, Bacillus subtilis DE111 probiotic cultures, and Bifidobacterium longum ES1 postbiotics in a single can.

Slice has to stay refrigerated to keep its live probiotic cultures alive, so it sits in the cold case rather than on the soda shelf. In Parade magazine's family taste test of nine prebiotic and probiotic sodas, Slice ranked highest for taste, appearance, and functional value. Available in Classic Cola, Orange, Lemon Lime, Strawberry, Grapefruit, and additional flavors, Slice has landed at Costco and other national retailers since its 2025 relaunch.

What makes Slice different from Poppi and Olipop? Slice combines prebiotics, probiotics, and postbiotics together — the only brand on this list with all three in one can, though the benefits of any specific blend remain unproven.

Why does Slice need to be refrigerated? Slice requires refrigeration because it contains live probiotic cultures that need to stay cold to survive, unlike many shelf-stable prebiotic sodas.

Where is Slice available? Slice is sold at Costco, through the official Slice website with direct shipping, and at select national grocery retailers — the store locator at slicesoda.com shows the nearest retailer.

Kombucha and Other Fermented Drinks

Long before prebiotic soda brands hit the beverage aisle, kombucha was already on shelves as a gut-friendly fermented drink. This fermented tea — traditionally said to have originated in China around 221 BCE — uses a SCOBY (symbiotic culture of bacteria and yeast) to transform sweetened tea into a probiotic-rich, naturally carbonated drink with organic acids, B vitamins, and antioxidants. GT's Synergy, the category pioneer since 1995, offers flavors like Gingerberry and Lemon Berry, all fermented for 30 days in small batches.

Health-Ade, founded at the Brentwood Farmers Market in 2012 by Daina Trout, her husband, Justin, and her best friend, Vanessa Dew, has grown into one of the nation's most recognized kombucha brands. Both brands use organic produce and avoid pasteurization, preserving the live cultures that give kombucha its health reputation. WebMD and the Cleveland Clinic note promising research on kombucha's antioxidants, blood sugar effects, and probiotic diversity, but most of its health claims still lack solid human trials.

How much kombucha should you drink a day? Many dietitians suggest keeping kombucha to roughly 4 to 12 ounces a day, and newcomers should start with 4 ounces to let the gut adjust. There is no official daily limit.

Does kombucha contain alcohol? Kombucha naturally produces trace amounts of alcohol during fermentation — most commercial kombucha brands contain less than 0.5% ABV, making them non-alcoholic beverages, though those with alcohol sensitivities should check kombucha labels.

Is kombucha safe for everyone? Pregnant individuals, those with compromised immune systems, and children should consult a doctor before regularly drinking kombucha, because the live cultures and trace alcohol may not suit everyone.

The Science of Gut-Friendly Sodas

Grand View Research valued the prebiotic and probiotic soda market at about $516 million in 2025, and estimates vary widely by firm. At the heart of the trend is a legitimate nutritional concept: prebiotics are non-digestible fibers that serve as food for beneficial gut bacteria, while probiotics are live microorganisms that add to the gut's microbial population. Together, they are thought to support a microbiome associated with digestion and immune function, though research on the small doses in a can of soda is limited.

The science is promising but still evolving. Quigley, the Houston Methodist gastroenterologist, notes that no large-scale human studies have yet evaluated whether the fiber levels in specific soda cans produce measurable microbiome shifts. OSF HealthCare cautions that prebiotics may cause flare-ups for people with irritable bowel syndrome or other digestive disease, and suggests that people with digestive conditions or compromised immune systems get prebiotics from food instead of soda. The broader consensus among registered dietitians is that prebiotic sodas are a smart upgrade from traditional soda — especially for heavy soda drinkers — but shouldn't replace whole-food fiber sources like garlic, onions, asparagus, oats, and bananas.

How much fiber should a gut-healthy soda have? Dietitians suggest looking for at least 5 grams of fiber per can — Olipop leads the category at 6 to 9 grams, while most other prebiotic sodas offer 2 to 5 grams. Daily fiber recommendations run from 25 to 38 grams.

Can prebiotic sodas cause side effects? Yes — consuming too much prebiotic fiber too quickly can cause gas, bloating, abdominal cramping, or loose stools, especially for those new to high-fiber diets, so prebiotic soda intake should increase gradually.

Are gut-health claims on soda cans FDA-approved? No — the FDA has not approved any specific health claims made by prebiotic soda brands, so phrases like "supports gut health" are marketing language, and the nutrition label is the better guide.

Sparkling Water & DIY Soda Alternatives

For those who want the fizz without any functional claims, sparkling water and home carbonation remain the simplest and most customizable healthy soda alternatives. Brands like LaCroix, Spindrift, and Bubly offer naturally flavored seltzer with zero calories and zero sugar. SodaStream, which PepsiCo bought in 2018, sells home carbonation systems that let users control exactly what goes into each glass. Fresh ginger and a little simple syrup make a homemade ginger ale, and a splash of pomegranate or mango juice turns sparkling water into a mocktail.

Soda alternatives can be matched to a health goal — kombucha for probiotic diversity, coconut water for post-workout electrolytes, and infused fruit water for calorie-free flavor. Skipping store-bought soda syrups and opting for natural fruit or fresh herbs in sparkling water cuts the artificial additives without losing the fizz. The best healthy soda alternative is whichever one keeps you from reaching for a can with 39 grams of sugar — a $3 prebiotic soda or a SodaStream loaded with fresh mint and lime.

What is the healthiest soda? Most registered dietitians point to plain sparkling water or a naturally flavored seltzer like LaCroix or Spindrift, with no added sugar or sweeteners. Among the sodas in this guide, Zevia has no sugar at all and Olipop has the most fiber.

Can SodaStream make healthier sodas? Yes, if you skip the included syrups. Carbonate plain water, then add fresh fruit, herbs, or a small splash of 100% juice.

What is the cheapest healthy soda alternative? Plain sparkling water or homemade carbonated beverages made with a SodaStream and fresh fruit are the most affordable healthy soda alternatives, typically costing a fraction of the $3–$5 per-can price of branded prebiotic sodas.
