Kettle & Fire bone broth is made with bones from organically raised chickens or cattle, then slow simmered for a solid 24 hours with organic vegetables, sea salt and herbs. All that simmer-time extracts insane amounts of protein, not to mention glycine, glucosamine, calcium, magnesium, phosphorus, and potassium. That's a long list of goodness, all of which your body converts into energy, stronger muscles, and a more effective immune system. Bone broth is also an amazing source of collagen, which is great for your skin, hair, nails and bones.
