Kettle & Fire Beef Bone Broth is made with 100% grass-fed and finished beef bones, apple cider vinegar, and only organic ingredients. Our beef broth has a calming, centering, and absolutely delicious flavor, making it perfect for sipping right from a mug. We source beef bones from farms that raise their animals without any added hormones or antibiotics. We combine 100% grass-fed and finished bones with organic ingredients like apple cider vinegar into steel kettles that simmer for 18+ hours to get the maximum amount of collagen, proteins, and amino acids into our tasty broth. One daily serving infuses your body with nutrients like collagen that are absent from most foods, and you'll feel the difference they make. Plus, we package our broth hot in a vacuum-sealed environment so that it lasts longer and tastes better. The packaging is also made from all-natural ingredients so it's recyclable.
