If you have been taking calcium tablet to do away with existing health issues, you need to be cautious now as too much calcium supplements may pose risk to health.


According to a study published in the journal Annals of Internal Medicine, excessive calcium supplements may increase the risk of cancer and instead one should concentrate on food sources for getting adequate nutrients.

Researchers found that supplemental doses of calcium exceeding 1,000 mg per day is linked to an increased risk of cancer death.

Fang Fang Zhang, associate professor at Tufts University in US, said: “As potential benefits and harms of supplement use continue to be studied, some studies have found associations between excess nutrient intake and adverse outcomes, including increased risk of certain cancers.”

“It is important to understand the role that the nutrient and its source might play in health outcomes, particularly if the effect might not be beneficial,” Zhang said.

The study used data from more than 27,000 US adults ages 20 and older to evaluate the association between dietary supplement use and death from all causes, cardiovascular disease (CVD), and cancer.

The researchers found that adequate intakes of vitamin K and magnesium were associated with a lower risk of death, while adequate intakes of vitamin A, vitamin K, and zinc were associated with a lower risk of death from CVD.
