Answer: Bone broth can be a good source of protein, an essential nutrient for muscle growth and maintenance. Bone broth is especially rich in collagen (the main protein found in bone), and for this reason, is often promoted for a wide range of health benefits.
Clinical studies show that collagen may help reduce joint pain associated with physical activity and osteoarthritis, increase bone mineral density, and help reduce wrinkles and increase skin elasticity. However, although bone broth has been promoted for such uses, most studies of these conditions have used collagen supplements, not bone broth. Bone broth has also been promoted for boosting the immune system and healing the digestive tract, although, again, these uses have not been proven with bone broth.
