Excessive calcium supplements may up cancer risk: Study

Taking excessive calcium tablets may increase the risk of cancer, according to scientists who say that getting adequate nutrients from food sources is more beneficial than consuming supplements.

The study, published in the journal Annals of Internal Medicine, also showed that adequate intake of certain nutrients reduces risk of death from any cause, when nutrient source is foods, but not supplements.

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