Bone Broth Nutrients Bone broth contains gelatin, which is essentially cooked collagen, says Whittel. (That's why good bone broths turn into a gel when they're cooled.) Gelatin in bone broth contains three key amino acids: glycine, which reduces inflammation and is important in the production of DNA and RNA; proline, which contributes to healthy collagen production in skin and arteries, helps heal cartilage and cushions joints; and glutamine, which aids in healthy brain function, muscle building and is important in digestive and immune health.
Bone broth is also rich in minerals, particularly phosphorus, magnesium, potassium, calcium and sodium, according to Whittel. She says that some of the minerals come from the breakdown of the bones and others come from vegetables that can used in making the broth.
Ironically, bone broth isn't overflowing with calcium. "You would think that bone broth would be a good source of calcium, but unfortunately not much of the calcium is present in the bone broth," says Shacter.
