Barley protein shakes contain sustainable protein

Rebbl's protein shakes contain a sustainable, Upcycled Certified, and non-GMO Project Verified plant protein blend that provides 26g of protein in each ready-to-drink bottle. Upcycling barley into a premium protein source utilizes every part of this powerful ancient grain, the company says. Upcycling transforms brewing coproducts, known as brewer's destarched grains (BDG), into a premium, plant-based protein source. Offered in three classic flavors of Chocolate, Vanilla and Cookies & Crème, the drinks contain only 4 grams of sugar.
