However, I did find some information:
On Vitamin B6:
Folic acid and vitamin B6 (pyridoxine) together perform a vital role in engendering the health of bone tissue. They help the body metabolize and excrete a substance known as homocysteine. High homocysteine levels are associated with defective bone formation (and, incidentally, with cardiovascular disease). Interestingly enough, menopausal women show an impaired ability to metabolize and excrete homocysteine. Furthermore, they tend as a group to be low in folic acid and vitamin B6. [1]
On Vitamin B12:
Another study, conducted at the University of California, San Francisco, linked low vitamin B12 levels to bone loss in older women... Researchers found women with the lowest levels of vitamin B12 (at or below 280picogram/mL) experienced significantly greater hip bone loss than women with higher levels (above 280 picogram/mL), according to the study... [2]
I also found it interesting that "Osteoporosis is second only to cardiovascular disease in terms of global healthcare burden" [3]. It seems to be a very prevalent problem that is rarely pointed out by nutritionists, schools, doctors, etc. Taking a bone class is really the first place that I've been encouraged to even think about bone health.
As always, I would love to have a deeper understanding of how the chemicals biologically affect the tissues we're discussing. I'm still in search of a good article on this subject, and will post when I find out.

Keep it up, Masha! I know it's discouraging sometimes when you can't find a lot of info on the topic you're trying to work with...wish I had some suggestions for you! It looks really good so far, though, so good job! :)
Even though you are having a tough time finding research aricles, you have some great info here! I didn't know that menopausal women had a difficult time metabolizing those needed minerals to the extent the article spoke of. It seems that they should be reccommending a "prenatal" type vitamin to this population. When I was pregnant, that was the first question I was asked - especially due to the folic acid included in these vitamins.
Great information!!!! I really enjoyed reading this. I was wondering if any of the literature discussed Veganism and B12 defficiency. Did the study you referenced use a population that had a "normal" diet or at least ingested the DRI for calcium? I was just curious because they said that the way B12 was linked to bone health is unknown, which makes me wonder if other dietary factors may be part of what causes the correlation.
