A new study published in the Journal of Clinical Endocrinology & Metabolism, showed that elderly people taking calcium supplements and vitamin D together may have a longer life expectancy than those who do not.
Conducted by University of Aarhus, Denmark, the study found a reduction of up to 9% in the mortality rate in those who took the supplements over a three-year period. The study involved more than 70,000 elderly, 86% female, with a mean age of 70 years.
According to the survey, this benefit was found with the daily intake of supplements containing 10-20 micrograms of vitamin D and 1,000 milligrams of calcium – the quantity corresponding to the recommendations of the Ministry of Health of Brazil. The study also noted that, alone, vitamin D had no impact on mortality reduction. The authors reached this conclusion after analyzing eight other clinical studies on the effects of supplemental vitamin D and calcium on health.
Dr. Lars Rejnmark, study coordinator, said that even though a decrease of 9% of the risk of death may seem a small benefit, over three years, this is very significant.
Although previous studies have shown that combining these two supplements may prevent osteoporosis in the elderly, this does not explain the decrease in mortality. According to Dr. Rejnmark, it may be that the supplements help reduce the incidence of cancer deaths, but other studies are needed to evaluate this hypothesis.

Learn more about calcium and vitamin D
Calcium can be found in foods such as dairy products, some vegetables, especially leafy greens (broccoli, cauliflower and cabbage), fish such as sardines and salmon, beans, and others. The Ministry of Health recommends consumption of 1,000 milligrams of calcium a day for adults and 700 milligrams for children aged 7 to 10 years.
Vitamin D promotes calcium absorption by the body after sun exposure. Vitamin D deficiency can cause rickets, osteoporosis, reduced immunity, and perhaps even increase the risk of cancer. Vitamin D is also related to the proper functioning of the heart, brain and the secretion of insulin by the pancreas. A significant amount of the vitamin is seen in some foods, such as liver, fatty fish and egg yolks.
