Calcium and vitamin D supplements ‘may be too much for some women’

18th June 2014

A new study has highlighted potential risks associated with taking calcium and vitamin D supplements for some older women.

These supplements are often recommended to postmenopausal women to improve bone health, but the new US study suggests they may send calcium excretion and blood levels too high for some patients.

A randomised placebo-controlled trial including 163 older females revealed that around about nine percent developed excess levels of calcium in their blood due to the supplements, while 31 percent experienced excess calcium in their urine.

This trend was generally observed among those with high starting levels of calcium and could potentially lead to kidney stones or other problems.

Dr Margery Gass, executive director at the North American Menopause Society, said: "I would recommend that women determine how much calcium they typically get through their food sources before taking a hefty calcium supplement. They may not need as much as they think."

Many women take supplements like these to protect against bone conditions such as osteoporosis, which particularly affects postmenopausal women.ADNFCR-8000103-ID-801729261-ADNFCR
