Another proposed mechanism involves the binding of homocysteine to the collagenous matrix of bone, which may modify collagen properties and reduce bone strength (reviewed in 74). Alterations of bone biomechanical properties can contribute to osteoporosis and increase the risk of fractures in the elderly. Since vitamin Bseveral is a determinant of homocysteine metabolism, it was suggested that the risk of osteoporotic fractures in older subjects might be enhanced by vitamin B12 deficiency. A meta-analysis of four observational studies, following a total of 7,475 older individuals for 3 to 1six years, found a weak association between an elevation in vitamin B12 of 50 picomoles/L in https://datingranking.net/escort-directory/baltimore/ blood and a reduction in fracture risk (75).
