Much of that effect is tied to raising vitamin D levels, a study found. The study looked both at how a calcium and vitamin D supplement changed cholesterol levels, and how it affected blood levels of vitamin D in postmenopausal women.
The women in the trial took either a supplement containing 1,000 mg of calcium and 400 IU of vitamin D3 or a placebo, daily. This analysis looked at the relationship between taking supplements and levels of vitamin D and cholesterol in some 600 of the women who had both their cholesterol levels and their vitamin D levels measured.
The women who took the supplement were more than twice as likely to have vitamin D levels of at least 30 ng/mL (normal according to the Institute of Medicine) as were the women who took the placebo. Supplement users also had low-density lipoprotein (LDL – the “bad” cholesterol) levels that were between 4 and 5 points lower. The investigators discovered, in addition, that among supplement users, those with higher blood levels of vitamin D had higher levels of high-density lipoprotein (HDL – the “good” cholesterol) and lower levels of triglycerides (although for triglycerides to be lower, blood levels of vitamin D had to reach a threshold of about 15 ng/mL).
Taking the calcium and vitamin D supplements was especially helpful in raising vitamin D levels in older women, women who had a low intake, and women who had levels first measured in the winter – what you might expect, due to lower sunlight exposure. Lifestyle also made a difference, the supplements did more to raise vitamin D levels in women who did not smoke and who drank less alcohol.
Whether these positive effects of supplemental calcium and vitamin D on cholesterol will translate into benefits such as lower rates of cardiovascular disease for women after menopause remains to be seen, but these results, said the authors, are a good reminder that women at higher risk for vitamin D deficiency should consider taking calcium and vitamin D.
