Our broth is made from highest quality organic chicken bones from birds that are free range and allowed to forage on organic pastures. We slow cook our broth up to 24 hours and use raw apple cider vinegar to help facilitate the release of collagen, amino acids, calcium, gelatine, magnesium, phosphorous and potassium. Ossa is proud of the very high natural protein content (collagen) of The Bone Broth, Non GMO, no soy, MSG, powders. B Corp Certified and Best for the Environment Honoree 2018.
