Organic super-herb beverages manufacturer Roots Extracts Berries and Leaves (REBBL) has closed a $10m investment led by Boulder Investment Group Reprise (BIGR).

It is expected that this investment will expand the firm's marketing efforts and improve the customer reach of super-herbs.

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

"This round is exciting because it allows REBBL to leverage the momentum of our growth and expand more rapidly."

BIGR managing partner and REBBL board member Duane Primozich said: "We're thrilled by the opportunity to partner with REBBL.

"It is an exceptional brand with fantastic products, talented and experienced management, and a truly authentic mission."

Last year, the firm closed an investment of $4m led by co-founder and managing partner of Powerplant Ventures and a member of REBBL's board Mark Rampolla.

REBBL chief executive officer Sheryl O'Loughlin said: "This round is exciting because it allows REBBL to leverage the momentum of our growth and expand more rapidly.

"I am so humbled to have some of the best and brightest leaders in the natural food and beverage industry supporting our company."

REBBL is claimed to have more than doubled in revenue this year. Its products include super-herb powered proteins and coconut-milk elixirs, which are sold in more than 2,500 stores.

All the products of the firm contain adaptogenic herbs, such as ashwagandha, and are certified organic, vegan, soy and dairy free, as well as genetically modified organism (GMO) free, super-herbed, and free of artificial flavours or thickeners.

The products are available at select Whole Foods Market and other retail stores.
