The claim

「Bone broth is the best calcium source」

Q: Bone broth is the best calcium source

Myth — Bone broth does not appear anywhere on the NIH list of calcium sources: milk, yogurt and cheese lead it, followed by canned sardines and salmon with the bones in, vegetables such as kale, broccoli and bok choy, and calcium-fortified foods like some tofu and soy drinks. Calcium in bone barely dissolves into the broth; what you drink is mostly water, fat and purines. If you want calcium, eat from that list.
