Ora Organic probiotic powder contains some of the most clinically documented and acid-resistant probiotic strains in the world, along with crucial prebiotics which serve as fuel for probiotics. They help the good bacteria thrive in your gut so your probiotics work smarter, not harder. Unlike most probiotics, this does not require refrigeration because it's freeze-dried! #readytotravel. And did we also mention it's delicious? As with all of Ora Organic products, this probiotic capsule is 100% vegan, dairy-free, gluten-free, non-GMO and contains no artificial ingredients.
