If you’re looking for a dairy-free protein shake that’s allergen-friendly and anything but boring, Rebbl is one of the best options we’ve tried. Instead of whey, they use an upcycled plant protein blend, which Rebbl describes as a novel ingredient created from destarched grains, a by-product from the brewing industry that would otherwise be thrown away. Combined with pea protein, it provides all nine essential amino acids to support muscle recovery, as well as prebiotic fiber for added gut health benefits.
“This protein drink is a great choice for individuals with lactose intolerance or those who choose a vegan diet,” explains Ballenthin. “Because both pea protein and the added agave inulin act as prebiotics, some people may experience mild bloating. If that occurs, it can help to start with smaller servings and gradually work up to a full bottle.”
Nutrition and weight loss writer SaVanna Shoemaker, RDN, tested the Rebbl drinks and describes the texture as slightly thick, smooth, and creamy, without being chalky. “These were some of the best-tasting and best-textured shakes I tried,” says Shoemaker. “They’re USDA Organic, non-GMO, and many flavors are vegan, though some are sweetened with honey.”
In terms of taste, Shoemaker found the lineup to be a mix of standouts with only a few misses. “The Lavender Tea Latte was delicious — like a mild and creamy cold chai tea — and one I’d definitely buy again,” she says. “The protein dark chocolate was mildly sweet with a rich flavor, while the vanilla had an overwhelming cinnamon note that was too strong for me.” She also points out that while the adaptogens and botanicals (such as ashwagandha and maca) make these shakes unique, the small amounts in each serving may not be sufficient to have a meaningful effect.
Ultimately, Rebbl shines for people seeking lactose-free protein shakes with creative flavors. While the flavors may be hit or miss, the smooth texture, adaptogen blend, and robust flavor options make it a standout among plant-based options.
