Emeryville, Calif.-based REBBL announced the launch of Sparkling Prebiotic Tonics, a line of plant-based beverages with 6 grams of prebiotic fiber to support digestive health. The effervescent drinks boast flavor profiles like cold-brew cola and ginger turmeric, with only 6 to 8 grams of sugar in each bottle, according to the company.

"Our new Sparkling Prebiotic Tonics fill a void in the market when it comes to low-sugar options that aid in digestive health, and they have the added benefits of high-integrity plant ingredients like elderberry, turmeric, and mate for an added layer of functionality," said Michele Kessler, REBBL's newly appointed chief executive officer, in a statement. "As with all of our REBBL products, our ingredients are organic and ethically-sourced with a portion of the proceeds going back to our nonprofit partner, Not for Sale, to help their innovative work around the world. We are so excited to continue to expand the brand in a meaningful way that our consumers will love."

REBBL Sparkling Prebiotic Tonics are available in the following varieties:

  • Forest Berry, which features elderberry, blueberry, bergamot, and craft-brewed Fair Trade Assam black tea. This vegan tonic contains a hint of vanilla and black tea while deriving 100 mg of natural caffeine from tea.
  • Mystic Mint combines craft-brewed yerba mate, peppermint, hibiscus and lemon. The vegan tonic derives 100 mg of caffeine from yerba mate.
  • Ginger Gold is an amalgamation of notes of ginger, turmeric, vanilla and citrus. Like the other REBBL Tonics, Ginger Gold features 6 grams of prebiotic fiber for digestion support, along with ginger, lemon, and cayenne pepper.
  • Cold-Brew Cola is a sparkling coffee tonic that is vegan and contains 120 mg of caffeine from coffee and 6 grams of prebiotic fiber.

All four flavors will retail for $3.49, exclusively at Whole Foods Markets nationwide.
