Our Certified Organic Beef Bone Broth is handcrafted the same way it has been for centuries. We start by using triple filtered water and Certified Organic Grass-Fed, Grass-Finished beef bones. We add locally sourced organic onions, organic fresh garlic, Celtic Sea Salt® by Selina Naturally® and Organic apple cider vinegar. The vinegar acts as a magnet to help pull the vitamins and minerals from the bones and into the broth. We then bring the broth to a boil and immediately reduce to a simmer. This slow simmer continues on for 48 hours.
