Study: Vitamin D and Calcium Supplements Linked to Increase in Cardiovascular Mortality
A recent study conducted by researchers from the University of Arizona has shed light on the long-term effects of vitamin D and calcium supplements on post-menopausal women. The study, which analyzed over 30,000 patients over a period of more than 20 years, revealed a concerning trend: while there was a reduction in the risk of developing cancer among women who took the supplements, there was also an increase in mortality from cardiovascular disease.
The study, published in the Annals of Internal Medicine, followed over 36,000 post-menopausal women with no history of breast or colon cancer. The results showed that women who took calcium and vitamin D supplements had a 7% lower risk of dying from cancer over the 22-year period. However, they also had a 6% increase in mortality due to cardiovascular disease.
The researchers noted that the incidence of cancer seemed to be influenced by whether the women were already taking supplements before the study began. In addition to mortality from cancer and cardiovascular disease, the study also looked at overall mortality and the rate of hip fractures, but did not find any significant effects of taking the supplements on these outcomes.
The findings raise important questions about the benefits and risks of long-term supplementation with vitamin D and calcium, especially for post-menopausal women. While these supplements are often recommended for maintaining bone health, the study highlights the need for further research to fully understand their impact on overall health. Women considering taking these supplements should consult with their healthcare provider to discuss the potential risks and benefits.
