The truth is that the interaction of calcium, fluorine and Vitamin D
on osteoporosis alone is a scientific mare's nest, and the North
American dairy industry sure isn't helping us to understand it.
Increasing Vitamin D as you get older probably does help - I aim for
400 IU/day myself now - but there is a lot of dispute about the two
minerals and how Vitamin D interacts with them.

I aim for 4000 IU either by intake or by UV induced
synthesis of vitamin D3. The bare minimum proven to
benefit osteoporosis is 800 IUs (20 mcg) as I recall.
Fluorine increases bone density but decreases bone quality.
The factors I'd look at would be such things as vitamin K
(at least 450 mcg per day), vitamin D3 (at least 1000 IU),
boron, DHEA, testosterone, calcium, magnesium, and
exercise.

Also it woulb important to avoid high vitamin A (retinol) intake. This
means that cod liver oil is not a good winter time vitamin D source as
it contains too much of retinol.
