New research from the University of Southampton has found no association between the use of calcium or vitamin D supplementation and cardiovascular events such as heart attacks. Calcium and vitamin D supplements, which usually come in the forms of tablets, are widely used and have been generally viewed as relatively safe, but some researchers have previously raised concerns over potential links with cardiovascular disease.
Investigators from the Medical Research Council Lifecourse Epidemiology Unit, University of Southampton (MRC LEU), used the internationally unique UK Biobank cohort, comprising over 500,000 men and women aged between 40 and 69 years, to explore relationships between use of calcium and vitamin D supplementation and the risk of cardiovascular events such as heart attacks.
The analysis accounted for a wide range of other potential influences, and did not detect any statistically significant associations between use of the supplements and events such as heart attacks, hospital admission for angina, or related deaths.
Calcium and vitamin D supplements are widely used in the population, and are particularly appropriate for those at risk of deficiency in either nutrient. In this situation there is good evidence that they provide a modest reduction in fracture risk, although do not replace medications specifically licensed for the treatment of osteoporosis.
