For crying out loud alreday. Talking about bones and calcium is akin to suscribing the piltdown man debacle. Bone, like all other body tissues, are living tissues. As such, ALL nutrients are required for proper bone develoment.
Bone is 1/3 minerals, 1/3 water and 1/3 protein. In seniors, due to a combination of dietary protein deficit often due to lack of appetite in turn often often linked to lack of taste oft due to zinc deficiency, creating a lack of desire to eat. Combine that with such pronounced activity lack and caloric expenditure, that there is little reason for hunger to develop (aside from the need for nutrition, but now we come full circle back to interest lack).
Finally, we have the extremly commom phenom. of hypochlorhydria, thus rendering any consumed protein, wholly or partially undigested. And thus, well, you can see where this goes.
Then there is the either functional or sub-acute pathologic dehydration.
Minerals required, well, all. Worry about specifics is putting the cart before the horse, unless one is referring to why deer antlers are prematurely disengaging from their owners heads!
Bone mineral integrity requires: Ca, Mg, Mn, Cu, Bo, Si, Fl, Vit A, spleen activity…and the list goes on and on.
We are not even talking about bone building hormones, and the effects of Wolffe’s Law (the piezo-electric effect of bone strengthening).
So I know of course that I am coming across as Mr full of myself, but the facts are what they are.
Bone health is not that complicated. Eat real foods, eat them slowly and well, and exercise – every day of your whole life, to whatever degree works for you.

Prairie Dog Giant Deer Antler Dog Chew ..
The team prepared 40 mm long blocks of dry antler and wet deer femur and measured the amount of force needed to bend the blocks to find out how flexible the materials were. Even though most bones are relatively brittle and inflexible when dry, the team found that the dry antlers are almost as stiff as wet bone: which is ideal for weapons that have to survive a lengthy pushing contest after the initial clash.
Kong Wild Whole Elk Antler Dog Bone.
Our Deer Antler Dog Bones sourced from New Zealand deer raised on grass-fed farms. The bone is then naturally air-dried to retain its goodness in a shelf-stable form. They’re great for oral health, long-lasting and dogs go crazy for them. Please note, these are not available in European or North American markets.
