Calcium and Vitamin D May Not Reduce Blood Pressure

Calcium and vitamin d supplements may not reduce high blood pressure or alter the risk associated with hypertension in postmenopausal women, according to a recent study by HealthPartners Research Foundation in Minneapolis.


The research team selected 18,000 women and studied the effects of 1,000 milligrams of calcium and 400 IUs of vitamin D3 on women 50 to 79 years old. After average follow-ups of seven years, there was no significant difference in the groups’ blood pressure or in the number who developed hypertension. Dr. Karen Margolis, leader of the research team commented on the study, “Shortcuts with dietary supplements cannot be substituted for encouraging people to adopt dietary patterns that have been shown to lower blood pressure and decrease the risk of hypertension.” She also suggests that women who start treatment at younger ages may have better success.

NBJ estimates that U.S. consumers spent $225 million on multivitamins aimed at cardio health and hypertension prevention in 2007. 90% of calcium sales were aimed at bone health in 2008, according to NBJ estimates.
