Drinking bone broth is not an ideal way to supplement calcium. Although bones contain calcium, it does not dissolve in large amounts into the broth during cooking. Therefore, the amount of calcium you get from bone broth is very limited. Dairy products, leafy green vegetables, and nuts provide calcium that is more easily absorbed by the body. Additionally, adequate vitamin D is crucial for calcium absorption. It is recommended to supplement calcium through a balanced diet and proper sunlight exposure.
