It has been scientifically confirmed that drinking reverse osmosis water causes more bodily harm and faster than most contaminants found in tap water. Just about everyone knows that Reverse Osmosis RO systems excel at removing water impurities, but few are aware that they also remove the beneficial minerals.
What's the big deal? After analyzing hundreds of scientific studies concerning demineralized or reverse osmosis water, the World Health Organization released a report stating that such water "has a definite adverse influence on the animal and human organism. Consumers have been so concerned with removing as many things from water as possible that they have forgotten to ask if the resulting water actually improves health or causes health problems.
It's assumed that no toxins equals better health, but there is simply more to healthful water than a lack of toxins, as the World Health Organization clearly points out. What is alarming is that consuming reverse osmosis water for even just a few months can create serious side effects. Illustrative of such short-term exposures are cases in the Czech and Slovak populations who began using reverse osmosis-based systems for final treatment of drinking water at their home taps in Within several weeks or months various health complaints suggestive of acute magnesium and possibly calcium deficiency were reported.
Among these complaints were cardiovascular disorders, tiredness, weakness or muscular cramps. Because reverse osmosis water doesn't have enough minerals, when it is consumed, it also leaches minerals from the body. This means that the minerals being consumed in food and vitamins are being urinated away.
Less minerals consumed plus more minerals being excreted equals serious negative side effects and big health problems. In a scientific study performed to see if minerals consumed in food can make up for the lack of minerals in reverse osmosis water, scientists concluded that "reduced mineral intake from water was not compensated by their diets Inadequate body water redistribution between compartments may compromise the function of vital organs.
Side effects at the very beginning of this condition include tiredness, weakness and headache; more severe symptoms are muscular cramps and impaired heart rate. One popular trend since the negative side effects of consuming reverse osmosis water was scientifically confirmed is the practice of adding minerals back into the reverse osmosis water. On this trend, the World Health Organization states that "possibly none of the commonly used ways of re-mineralization could be considered optimum, since the water does not contain all of its beneficial components.
In the case of borderline deficiency of a given element, even the relatively low intake of the element with drinking water may play a relevant protective role. In the developed countries, virtually all public water supplies are treated, at least to control pathogenic organisms. In these countries, many consumers have chosen to go beyond this level of treatment for their personal supply of drinking water.
Over the last 60 years, RO technology has developed, improved and is recognized for its ability to reduce the concentrations of all classes of contaminants in water supplies: suspended solids, salts, organics and microorganisms. The introduction of POU RO systems has given the consumer an inexpensive tool to ensure that their drinking water is largely free from health-related contaminants.
In fact, the reverse-osmosis process removes 92 to 99 percent of beneficial calcium and magnesium. What is alarming, is that consuming RO water for even just a few months can create serious side effects.
But it gets even worse. When it is consumed, it also leaches minerals from the body. This means that the minerals being consumed in food and vitamins are being urinated away. Hence, whatever the claims could be from the RO suppliers, drinking water treated using RO technology is definitely hazardous to health.
If the osmolality of the fluid to be filtered by the kidney is lower than normal lower solute concentration, such as low TDS water nervous and hormonal feedback mechanisms cause the kidney to excrete more water than normal and thus maintain the ion concentration of fluid to normal values. The opposite is true if the ion concentration of the fluid to be filtered is higher than normal.
Minerals in drinking water are required A claim is made that minerals in water are absorbed into the bloodstream more quickly that from food. As far back as , one of the authors wrote an article addressing this issue. Another claim is that humans need the beneficial minerals e. No two drinking-water sources are the same with regard to mineral concentration or any other parameter, for that matter , and even supplies with very high hardness levels would only provide about 6. The rest would have to come from food.
Myth: RO water will attack the body Yet another claim is that RO purified water is so pure that it will attack the mucous membranes in the body and cause harm. This water is all described as low TDS water. There are numerous scientific studies as far back as 3 addressing the health effects of drinking low TDS water.
There is also significant anecdotal evidence of humans consuming low TDS water for extended periods of time without any known health effects.
An example of this is the city of Vancouver, BC, Canada. There are alternative technologies such as natural zeolites, CDI, etc. This is a broader subject for another article addressing their limitations. Fact : It is critically important to remember that it is the water, not the soluble or suspended minerals and other constituents that serve as a solvent and medium for the transport of nutrients and wastes to and from cells throughout the body.
In point-of-fact, it must be noted that the US Navy has used distilled water with less than 3-ppm TDS aboard navy vessels for more than 50 years. Submarine crews typically drink nothing but low-TDS purified water for months at a time, all with no reported ill effects. They do not consider low-TDS water to be a problem and have no minimum standards. No ill-health effects were observed during a one-year test. Many hundreds of thousands of RO drinking-water appliances have been sold residentially over the past 40 years without any reported ill health effects from consumption of this type of water.
Myth: RO wastes water A primary criticism of RO technology has been that it wastes too much water and that membranes must be replaced frequently. It is important to realize that any technology designed to remove a contaminant from a water stream has to separate and collect the contaminant. Ion exchange resins and activated carbon, respectively, exchange and adsorb the contaminants, but they still have to eventually be removed, by generating a waste stream or by discarding the resin.
In the case of RO, the wastewater reject or concentrate stream is continuous. In this technology, the term recovery refers to the percentage of feedwater flow that passes through the membrane and becomes permeate purified water.
Reverse Osmosis RO systems to purify water are in use extensively. Besides the aqua companies that market RO water personal water purifiers are also preferred by many households. RO system off course removes water impurities.
After analysing hundreds of scientific studies concerning RO water, the World Health Organization states that such water has a definite adverse influence on the animal and human organism. What is alarming is the fact that consuming RO water for even just a few months can create serious side effects.
Czech and Slovak populations who used reverse osmosis water developed various health complaints suggestive of acute magnesium and possibly calcium deficiency within several weeks or months.

Less minerals consumed plus more minerals being excreted causes serious negative side effects and big health problems. In a scientific study performed to see if minerals consumed in food can make up for the lack of minerals in RO water, scientists concluded that reduced mineral intake from water was not compensated by their diets.
Low-mineral water was responsible for an increased elimination of minerals from the body. Consumption of RO water leads to the dilution of the electrolytes dissolved in the body water. Inadequate body water redistribution between compartments may compromise the function of vital organs. Side effects at the very beginning of this condition include tiredness, weakness and headache; more severe symptoms are muscular cramps and impaired heart rate.
Long-term consumption of acidic filtered water devoid of essential elements produced by RO filters is unhealthy. Recent studies suggest that RO water may be a risk factor for hypertension and coronary heart disease, gastric and duodenal ulcers, chronic gastritis, goitre, pregnancy complications and several complications in new-borns and infants, including jaundice, anaemia, fractures and growth disorders. When used for cooking, RO water was found to cause substantial losses of all essential elements from food vegetables, meat, cereals.
In contrast, when mineralized water is used for cooking, the loss of these elements is much lower, and in some cases, even higher calcium content was reported in food as a result of cooking. According to the World Health Organization the practice of adding minerals back into the reverse osmosis water could not be considered optimum, since the water does not contain all of its beneficial components.
In the case of borderline deficiency of a given element, even the relatively low intake of the element with drinking water may play a relevant protective role. It is practically impossible to recreate natural water with all of its minerals and trace elements from RO treated water. More recent studies have provided additional information about minimum and optimum levels of minerals that should be available in demineralised water.
Besides the adverse effects described above RO systems also waste per cent of water during filtration. Proper boiling must be ensured.
