How important are minerals in drinking water?

Water is indispensable for human survival and plays a significant role in the optimum functioning of the body. If that weren’t enough, it is  he main constituent of all basic body fluids such as saliva, blood, synovial fluid, urine, etc. It is imperative to understand that while the molecular formula of water is H2O, natural water also contains minute quantities of essential minerals and trace elements. In fact, research suggests that drinking water is quite the vital source of minerals for the human body. This is because, minerals and trace elements that are found in water exist in their ionized form, and such ions are easily absorbed by our gastrointestinal tract. 

A total of 21 mineral elements including calcium, magnesium, sodium, potassium, and other trace elements are known to be essential for humans. Minerals are naturally occurring inorganic elements or compounds such as gold, silver and carbon, or as a combination of two elements such as common salt (sodium + chloride). Some common minerals essential for health are calcium - for bones and teeth, magnesium- for healthy nervous system and bones, iron- for the production of haemoglobin, potassium- to keep the muscles and nervous system healthy, zinc - for healthy immune system, and sodium- to maintain balance of water around the cells.

A balanced diet usually provides all of the essential minerals however, some minerals obtained from water are better absorbed than minerals obtained from food. Dr. Chanda Gokhale, Doctorate in Food Science and Nutrition explains, “Natural mineral waters may be an essential source of calcium, magnesium and other minerals. Our body can efficiently utilize calcium and magnesium present in mineral water as they have a high bioavailability.

A study indicated that mineral water with higher concentrations of magnesium constitutes a calorie-free magnesium source that contributes to optimal magnesium supply.6

Minerals in drinking water can significantly supplement dietary intake. As the bioavailability of calcium and magnesium in water is usually better than that in food, both elements can be absorbed better through water rather than through food. This is owing to the fact that food contains other components that combine with these minerals to form compounds and this decreases the bioavailability of the minerals. Healthy water needs more minerals but unfortunately not all sources of water are high in minerals.

Mineral water comes from underground reservoirs which have been enriched with nature’s most precious minerals and naturally purified by the soil bed. However, this water is not fit for direct consumption and is further processed for purification. Several purification techniques strip the water of essential minerals.

Commonly used purification techniques include reverse osmosis (RO) or simply boiling of water. RO water filters are designed such that they not only eliminate contaminants from the water but also remove minerals that are essential for maintaining our health. The resulting water is either devoid of necessary minerals or contain them in very trace quantities.

In order to ensure adequate mineral consumption from water, it is imperative to be aware of what kind of processing your drinking water is being subjected to. Water containing recommended levels of total dissolved salts (TDS) is good for health. If you are consuming water that is subjected to purification methods such as RO, ensure that you switch to water that has dissolved minerals or that which has been enriched with added minerals, such as some brands of bottled water.

Drinking mineral-rich water holds tremendous health benefits, however it isn’t enough to simply consume the recommended daily amount of water. It is equally, if not more, vital to make sure that you consume water that is free of pathogens and contains the right level of minerals for the seamless functioning of your body.
