Eating bones, including those in bone broth or small animal bones, provides bioavailable calcium.

“you know if you it's difficult to say the RDA for calcium for most people is gonna be a couple of grams of calcium which you know would be a couple of bytes of bone would give you plenty of calcium a lot of people think that you should consider balancing your calcium and your phosphorus that's kind of something that is familiar to veterinarians and veterinary medicine the calcium phosphorus balance we don't think about it so much in Western medicine but there's a little bit of phosphorus in bones but you know I think if you get a couple of grams and bone you'll be fine in terms of your calcium phosphorus balance so it's not much you don't have to eat a whole bone but a couple of bytes of bone a day it's gonna be plenty for most people”
