In a recent study published in the Journal of Clinical Endocrinology and Metabolism, researchers found that seniors who take vitamin D and calcium have longer life expectancy than their peers.
Past studies have shown that vitamin D and calcium could prevent falls and decrease the risk of fracture. In the new study, researchers analyzed the effect on mortality among seniors who took vitamin D alone or vitamin D with calcium.
Researchers used data from eight trials with more than 70,000 total participants. 87% of the participants were women. The median age of the participants were 70 years. Participants were randomly assigned to take vitamin D alone or a combination of vitamin D and calcium. The average dose of vitamin D was 10 to 20 micrograms. The dose of calcium was 1,000 milligrams per day.
The results revealed that the combination of vitamin D and calcium increased the life expectancy in the participants. Death rate decreased by 9% in participants who took vitamin D with calcium during the three-year study. Lars Rejnmark, PhD, the lead author of the study said “Our results showed reduced mortality in elderly patients using vitamin D supplements in combination with calcium, but these results were not found in patients on vitamin D alone.”
There are some natural sources to obtain vitamin D and calcium, such as exposing to sunlight, eating oily fish: cod, salmon, tuna, drinking milk, eating eggs, mushrooms and shrimps.
