Low-carb CBD seltzers are having a moment, and it’s easy to see why. Health-conscious shoppers want something bubbly, refreshing, and relaxing without the sugar rush (or the hangover that often comes with alcoholic seltzers). Industry analysts note that low-calorie, low-sugar cannabis and CBD beverages are one of the fastest-growing corners of the functional drinks market, driven by consumers who want wellness benefits in a can.

At the same time, public health agencies remind consumers that most CBD drinks are not FDA-approved treatments; only one purified CBD medicine (Epidiolex) is approved for specific seizure disorders, and non-FDA-approved CBD products can vary widely in quality. So, shoppers are getting smarter: they want brands that combine low carbs with transparent testing and careful formulation.

Here’s a look at some standout low-carb CBD seltzers that tend to tick those boxes.

Day One – Ultra-clean and zero everything

Day One’s sparkling CBD waters are built for minimalists: each 12-ounce can delivers around 20 mg of CBD with zero calories, zero sugar, and zero carbs, flavored with real citrus juice and natural flavors. It’s a go-to option for shoppers who want a crisp, classic seltzer feel with a functional twist, without sacrificing carb goals or keto plans.

Weller – Zero-carb bubbles with broad-spectrum CBD

Weller’s Tangerine, Peach Mango, and Black Cherry sparkling waters each contain 25 mg of broad-spectrum CBD, and the brand leans hard into the low-carb lifestyle: zero calories, zero carbs, and zero sugar per can. For consumers who track macros closely or follow low-carb diets, Weller offers an easy fit — especially for people who want a little CBD support around workouts or winding down without adding to their daily intake.

MAD TASTY – Flavor-forward and sugar-free

MAD TASTY has carved out a niche with bold flavors like Unicorn Tears, Grapefruit, Yuzu Citrus, and Watermelon Kiwi. Each can features 20 mg of hemp extract and zero sugar, with a light, fruity profile that feels closer to a “treat” than plain sparkling water. For low-carb shoppers who miss more playful soda flavors, MAD TASTY delivers sweetness from natural flavors rather than added sugar.

Wyld CBD – Real fruit and very low carbs

Wyld’s CBD sparkling waters lean into real fruit and targeted effects. A 12-ounce can of certain flavors delivers about 5–10 calories, less than 1–2 grams of carbs, and 0–1 gram of sugar, depending on the variety, with CBD doses ranging from 25–50 mg (some also include CBN for extra relaxation). While not fully carb-free, they sit comfortably in the “low-carb” category and appeal to shoppers who prioritize natural juice plus hemp extract and third-party testing.

Recess & Daytrip – Low-calorie lifestyle seltzers

Brands like Recess and Daytrip helped popularize CBD seltzers as lifestyle drinks. Recess’s hemp-infused sparkling waters typically land around 20–25 calories per can with a small amount of carbs from juice, fitting into many reduced-carb lifestyles. Daytrip, meanwhile, offers zero sugar and about five calories per can, pairing CBD with mineral water and natural flavors for a bright, dry finish.

A quick note on safety and shopping smart

Because most CBD drinks are not FDA-approved therapies, agencies encourage consumers to be cautious, especially regarding dosage, potential drug interactions, and use during pregnancy or breastfeeding. Savvy shoppers look for brands that publish third-party lab tests, clearly label CBD content per can, and keep sugars and carbs low to match their wellness goals.

For anyone chasing a bubbly, low-carb alternative to cocktails or sugary sodas, these CBD seltzers offer a refreshing middle ground: light on carbs, big on flavor, and crafted for modern wellness routines.
