Drink Mineral Water to Get Calcium For Your Body

Researchers in Germany have found a natural yet effective way to get enough calcium for the body along with milk and other dairy products. Drinking mineral water can fulfil our body’s daily calcium requirement, found a team of researchers at Leibniz University Hannover in Germany.

And to obtain adequate amount of this mineral, they solely depend on supplements. But not anymore! As the German researchers have found mineral water is an efficient additional source of dietary calcium, a major component of mineralized tissues essential for normal growth and maintenance of bone.

Calcium-rich mineral water can also be a low-calorie alternative to drinking milk or taking supplements, the study suggests.

Theresa Greupner of Leibniz University Hannover, in Germany said: “The special feature of mineral water as a source of calcium is as a calorie-free alternative to milk and dairy products. In a world with a steadily growing number of overweight and obese people it is important to reduce the energy intake and to promote alternatives to satisfy the calcium demand apart from high caloric milk and dairy products.”

In order to determine how well the human body can absorb calcium from five different products, German researchers recruited twenty-one healthy males and females, and tested on them three types of calcium-rich mineral water (MW 1, MW 2, MW 3) with different concentrations of minerals; milk and a calcium supplement, each containing 300 mg of calcium.

The researchers were surprised to find that there was no difference in calcium absorption from all the five products included in the study. What’s more, presence of other minerals in the mineral water were not seen to affect calcium absorption.

The content of calcium in the mineral water can be determined by their label as most mineral waters in the market list mineralization on the label. The higher the amount of calcium, the better the water is as a source of calcium, Greupner said.

In Germany, 1,000 mg/day of calcium is recommended for adult individuals while in the US this amount rises to 1,300 mg/day. To meet the German standard daily requirement of calcium, a person would need to drink two liters of 500 mg/L mineral water a day, or more than three eight-ounce cups of milk.

Dr. Maria Luisa Brandi of the University of Florence in Italy, who wasn’t involved in the current study, welcomed the current study findings, saying: “The concept is well established in medicine, we recommend water with high calcium content for osteoporotic patients.”

In a 2004 study, Brandi and her colleagues showed that calcium from mineral water was equally well absorbed as calcium from milk.

The study was funded by the Association of German Mineral Water Bottlers, and published online June 19 in the Journal of the American College of Nutrition.
