There are a lot of studies with conflicting results about the correlation between blood
levels of vitamin D and lipid profile (total cholesterol, LDLc, HDLc) and the effect of
treatment with vitamin D supplements on it. This study aimed to investig
ate the effect of
vitamin D and calcium supplements on lipid profile.
This study included 59 volunteers who received these supplements for prevention of
osteoporosis as a prescription from orthopedic doctors between 11/2016 to 1/2018. The
average of age was 49±8 years. The plasma values of TC, LDLc, HDLc were measured
using enzymatic colorimetric method ( Biosystems kits ) in Tishreen hospital before
treatment and after two months. The results were analyzed by T-Student test, and P value
<0.05 was considered significant. The mean plasma levels of LDLc before treatment were
(100.983 ±28.36) mg/dl, and after two months of treatment were (102.249±27.478) mg/dl,
and the difference was not significant. The mean plasma levels of HDLc before treatment
were (68.056 ±14.369) mg/dl and after two months of treatment were (62.715 ± 14.39)
mg/dl, and the difference was significant. We advise to measure plasma lipid levels during
treatment with these supplements depending on the changes that observed in this study.
In research we studied the effect of vitamin C on the level of total
cholesterol ،triglycerides ، (HDL) and (LDL) in the stressful
rabbits blood by hydrogen peroxide (H2O2) . We used 30 rabbits
were divided into three groups:First groupnot stresse
d (control
group) ، Second group (Group stressed by H2O2) left without
treatment until the end of the experimental period ، third group
(Group stressful by hydrogen peroxide) was given orally vitamin C
solution at a rate of 100 mg / kg of body weight per a day for five
weeks.
