What is healthy water ?

In general, we can assume that food is the principal source of nutrients for humans. Water can also be a source of beneficial dietary substances, as well as harmful contaminants including chemicals and microorganisms that can mitigate dietary components. Presence or absence of beneficial ions can affect you over the long term, just as the presence or absence of toxicants.

Water components can supplement dietary intake of trace micronutrients and macronutrients or contribute undesirable contaminants. As is usual in toxicology and nutrition, the line between health and illness is not a single line but a matter of optimal intake, versus adequate intake, versus intake that is inadequate to maintain good health, versus a toxic intake that will lead to illness. Young children, pregnant women, the aged and infirm, and the immune compromised can be more sensitive than the typical healthy adult to essential and hazardous dietary components. 

Calcium/Magnesium and Cardiovascular Diseases

Over about 50 years, a body of epidemiology work especially in UK, USA, Canada and Scandanavia has fairly consistently suggested that some types of cardiovascular disease mortality rates are inversely proportional to the hardness of the water supply. Calcium and magnesium are the principal components of hard water so many researchers have concluded that calcium and particularly magnesium may have a protective effect. There are biochemical arguments that can be raised in support of the hypothesis, however the issue is not resolved with absolute certainty. More recent studies seem to be finding greater positive effects from magnesium rather than calcium intake particularly in regard to reduced risk from stroke or ischemic heart disease.


The health significance of these hypothesized relationships with drinking water is dependent upon many factors including diet, lifestyle, your genom, smoking, age, stress, work and other confounders (Ref.: WHO, 2005: Nutrients in drinking water). No easy answers here to be found !

Drinking water has generally not been relied upon as a significant contributor of trace nutrients, but rather as a supplement. Dietary supplementation is, however, widely practiced for general benefit e.g., Vitamin D in milk, Vitamin C in drinks, iron and B Vitamins and folic acid in bread.

The principal therapeutic substance added to drinking water in some areas is fluoride. The intent is to strengthen tooth enamel. Water fluoridation is controversial in some quarters, but generally believed by the dental community and many public health officials to be beneficial without demonstrable risk. Fluoridation is a matter of national policy and has been stopped in more and more places.

Sources of flouride is black tea, tooth paste, raisins, wine, teflon coated cookware, remains of pesticides on fruits and vegetables etc. Flourides are abundant on earth and is an unavoidable component in our diet. So, why add it to water?


Nitrate in water mainly comes from agricultural fertilisers. In Denmark (farmland all over) app 60% of the nitrate used is lost to the environment and is washed out in rivers, lakes and fjords – or simply seeps down into the water reservoirs. 

Nitrate in drinking water is regarded as a health risk by both WHO and EU. In EU the limit is set to 50 milligram per liter. This limit is now questioned after a survey from Århus University (Denmark, 2018) where a significant corrolation between colonic cancer and nitrate is shown, even in small doses ( app 4 mg/L).

Nitrate is also related to fetal growth restrictions. A study (Denmark, february 2021) observed evidence of a small decrease in term birth weight and body length.

Unwanted chemicals in water

Water can absorb just about anything, so if you look for a certain substance, you might be able to find it in water. If you do not, you will never know. That is the challenge with water tests – they show what you look for, and only that. That means that any laboratory will not promise that a given water test is perfect drinking water – only that the components found is above or below the min/max values in the local drinking water regulations.

A standard water test may check for 10-20 components in water, the most important ones. But looking for other things will cost extra and may require laboratory facilities of a certain caliber. Checking for flouride, chlorine, arsenic, lead, mercury, PCB’s (polychlorinated biphenyls), dioxins, DDT, HCB (Hexachlorobenzene, one of many pesticides), dactal (dimethyl tetrachloroterephthalate, one of many herbicides), MtBE’s – the list can be endlessly long – will cost a lot and lead to the good question: Is our water still good enough to drink? Short term and long term effects ? 

Here are some good news: WaterStillar systems in combination with a broad spectrum carbon post-filter will remove just about any of these components. Safe water, we call it. You then add the minerals or taste you desire, in full control of your drinking water.

The “rainwater” hanging upside down that we collect.

Fresh, fresh water – new, not old water

The drinking water from a WaterStillar system will in aveage be only hours old, when you enjoy it. Just hours ago it was a gas (H and O) and has now been joined again into the solid form of water. In a sterile environment where no harmful metals or chemicals will migrate into the water. Just like nature has done it since the beginning of time, solar powered as well 🙂

This means that no contaminant has time or access to the water. This is a big argument for keeping water clean over time: It is made constantly and does not contain whatever is in the ground where it is pumped up after decades or more.
