New research conducted by Katherine Tucker, PhD, of Tufts University, examined dietary factors in relation to osteoporosis and uncovered a positive association between vitamin B-12 and bone health. In other words, the authors conclude that vitamin B-12 deficiency may be an important modifiable risk factor for osteoporosis.
βOsteoporosis is becoming a much greater issue now that people are living so much longer,β said lead author Tucker. βOur study provides support for a way in which people can actively lower their risk of osteoporosis and help to preserve quality of life.β
Tucker and her colleagues measured bone mineral density β a measure of bone quality β and vitamin B-12 level in more than 2,500 men and women participating in the Framingham Osteoporosis Study. They found that both men and women with low vitamin B-12 levels had on average lower bone mineral densities β putting them at greater risk of osteoporosis β than men and women with higher levels.
βThis is the first large scale study of its kind to show an association between low vitamin B-12 and low bone mineral density in men and it confirms other reports of this association in women,β said Tucker, βIt shows that getting enough vitamin B-12 from meats, poultry, fish and dairy products may be important for both men and women in maintaining strong bones. Some individuals, particularly older people, have difficulty absorbing vitamin B-12 from foods, however, and inclusion of breakfast cereals fortified with vitamin B-12 or use of vitamin B-12 supplements offers additional protection.β
