The action of vitamin D on serum lipids.
10 September 2010
Norwegian researchers realized two studies, a cross-sectional one in 2008 (8018 non-smokers and 2087 smokers) and a longitudinal one from 1994-95 to 2008 (1762 non-smokers and 397 smokers) in order to examine the link between plasma concentration of 25-hydroxyvitamin D and serum lipid profile. The cross-sectional study allowed to underline a significant increase in total cholesterol (LDL cholesterol and HDL cholesterol) and a significant decrease in the ratio LDL/HDL and in the rate of triacylglycerol in plasma associated with the increase in the level of 25-hydroxyvitamin D. Thanks to the longitudinal study, an association over 14 years between the increase in 25-hydroxyvtamin D and the decrease in triacylglycerol has been shown. Thus, it seems that a high level of vitamin D intake promotes a better serum lipid profile.
High serum 25-hydroxyvitamin D concentrations are associated with a favorable serum lipid profile.
