Have you heard of a potential interaction between vitamin E and bone health? A recent study from Spain evaluated the relationship between vitamin E status and osteoporosis in early postmenopausal women . Anthropometric data, osteoporosis risk factors, vitamin E serum levels, bone mineral density (BMD) and other serum parameters that may influence bone mineral density in postmenopausal women were analyzed in a cross-sectional study. The associations between osteoporosis and age, age of menopause, body mass index, osteocalcin, calcium, vitamin D, vitamin E (measured as 25-hydroxyvitamin D and as the α-tocopherol : lipid ratio, respectively), bone alkaline phosphatase, smoking status, leisure physical activity and alcohol intake were modeled by a multivariate logistic regression and multi-linear regression analysis in 232 early postmenopausal women. A lower vitamin E : lipid ratio was associated with osteoporosis in multivariate logistic regression. In a multivariate linear model with BMD of the lumbar spine as a dependent variable, the vitamin E : lipid ratio was clearly related with BMD of the lumbar spine ([i]F[/i] ratio = 6.30, [i]p[/i] = 0.002). BMD of the lumbar spine was significantly higher in the highest tertile of the vitamin E : lipid ratio than in the lowest tertile. The mean vitamin E : lipid ratio was significantly lower in osteoporotic postmenopausal women ([i]T[/i] score ≤ -2.5) (3.0 ± 0.6 μmol/mmol) than normal postmenopausal women ([i]T[/i] score > -1) (3.5 ± 0.7 μmol/mmol) using multivariable-adjusted BMD. These findings highlight that vitamin E may increase BMD in healthy postmenopausal women.
