Organic super-herb beverages manufacturer REBBL has expanded its product portfolio with the launch of Sparkling Prebiotic Tonics.

The company noted that the Sparkling Prebiotic Tonics is a line of hydrating plant-based beverages, containing six grams of prebiotic fibre to support digestive health.

REBBL CEO Michele Kessler said: “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.

“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.”

The beverage is available in Forest Berry, Mystic Mint, Ginger Gold and Cold-Brew Cola flavours.

Forest Berry tonic includes elderberry, blueberry, bergamot and craft-brewed Fair Trade Assam black tea, while Mystic Mint is claimed to support effervescent hydration with its craft-brewed yerba mate, cooling peppermint, hibiscus and lemon.

Ginger Gold contains notes of spicy ginger, earthy turmeric, warming vanilla and bright citrus and Cold-Brew Cola is a sparkling coffee tonic, which said to be energising and fortifying.

The company added that its Sparkling Prebiotic Tonics range contains 8g of sugar per bottle and will be available at all Whole Foods Markets across the US for $3.49.

In December 2016, REBBL closed a $10m investment led by Boulder Investment Group Reprise (BIGR).

The investment round also saw the participation of Powerplant Ventures and individual investor John Foraker.
