Studies Find Drinking Reverse Osmosis Water Negatively Impacts Health

Many people erroneously believe that reverse osmosis (RO) water is the best drinking water as it is pure and void of contaminants. However one could also say that RO water throws the baby out with the bathwater in the sense that it also removes the naturally occurring  healthy alkaline minerals. RO water is never found in nature, and when given the choice between RO water and mineral water, animals will always choose mineral water.

Distilled water is also devoid of minerals, soft water contains a low mineral content, and most bottled waters contain RO water.

Studies show that there are actually several detrimental health effects that can result from long term reverse osmosis/distilled/soft water consumption. A World Health Organization (WHO) report by Frantisek Koziek states:

In the late 1970’s, the WHO commissioned a study conducted by a team of researchers of the A.N. Sysin Institute
of General and Public Hygiene and USSR Academy of Medical Sciences under the direction of
Professor Sidorenko and Dr. Rakhmanin. The final report concluded that “not only does completely demineralised water (distillate) have unsatisfactory organoleptic properities, but it also has a definite adverse influence on the
animal and human organism”.

Experiments in animals, primarily rats, for up to one-year periods have repeatedly shown that the intake of distilled water or water with TDS ≤ 75 mg/L leads to: 1.) increased water intake, diuresis, extracellular fluid volume, and serum concentrations of sodium (Na) and chloride (Cl) ions and their increased elimination from the body, resulting in an overall negative balance.., and 2.) lower volumes of red cells and some other hematocrit changes. Results of experiments in human volunteers evaluated by researchers for the WHO report  are in agreement with those in animal experiments and suggest the basic mechanism of the effects of water low in TDS (e.g. < 100 mg/L) on water and mineral homeostasis.

Other more recent studies suggest that the intake of soft water (water low in minerals), may be associated with higher risk of fracture in children (Verd Vallespir et al. 1992), certain neurodegenerative diseases (Jacqmin et al. 1994), pre-term birth and low weight at birth (Yang et al. 2002), some types of cancer (Yang et al. 1997; Yang et al. 1998, Yang et al. 1999a; Yang et al. 1999b; Yang et al. 1999c; Yang et al. 2000), an increased risk of sudden death (Eisenberg 1992; Bernardi et al. 1995; Garzon and Eisenberg 1998), a higher risk of motor neuronal disease (Iwami et al. 1994), and preeclampsia (Melles & Kiss 1992).

When used for cooking, soft water was found to cause substantial losses of all essential elements from food (vegetables, meat, cereals). Such losses may reach up to 60 % for magnesium and calcium or even more for some other microelements (e.g., copper 66 %, manganese 70 %, cobalt 86 %). In contrast, when hard water is used for cooking, the loss of these elements is much lower, and in some cases, an even higher calcium content was reported in food as a result of cooking.

So how can you get more minerals in your water? Stop drinking bottled waters which do not contain minerals. If you have a RO system or live in a soft water area you can add a Remineralizer to your filtration system which will add calcium and magnesium into your water. If you live in a hard water area, get a high quality water filtration system that will reduce the contaminants but leave the healthy alkaline minerals. The addition of an electric water ionizer can then make those minerals more bio-available.

Why Reverse Osmosis Water is Harmful to Health

The extreme water filtration process known as reverse osmosis rids tap water of virtually all nasty toxins, contaminants and bacteria, making it as pure and crystal clear as can be.

Sounds great, right?

Not exactly.

The problem with reverse osmosis (R/O) is that it works TOO well. In addition to removing all of the impurities, it also strips the water of all the valuable alkaline minerals your body needs to thrive. Essentially, R/O water is dead and lifeless, and most bottled waters on the market today are made with R/O water, not the pristine mountain spring water the ads may lead you to believe.

Although reverse osmosis water is very pure, you will never find it in nature. Water in nature always has total dissolved solids (TDS) in it. TDS are dissolved substances or minerals found in natural waters, which are what give the water life and help to nourish our bodies.

Due to the removal of alkaline minerals, R/O water has an acidic pH level instead of a neutral or alkaline pH which municipal tap water sources mandate. It also has a positive oxidation reduction potential (or +ORP) value, which means it is oxidizing to the body and creates cell-damaging free radicals.

When we consume acidic foods and liquids, our bodies are forced to rob themselves of alkaline minerals like calcium from our bones and magnesium from our heart to offset the unnatural imbalance, creating a mineral deficiency!

Over time, this continuous act of robbing Peter to pay Paul can take a real toll on our health. It’s no wonder that heart disease, osteoporosis, cancer, vision loss and other lifestyle-related diseases are rampant in our society today–most of us are drinking the wrong kind of water!

R/O systems waste approximately five gallons of water per gallon made, and that’s not including the water and oil needed to create the plastic bottles they often come in! With many scholars predicting a water and oil crisis in the not-so-distant future, it’s important to be water wise now more than ever.

A Better Drinking Water Solution

Alkaline ionized water from a Chanson water ionizer is full of bioavailable minerals, has an alkaline pH and an energizing, free-radical fighting -ORP. Chanson ionizers duplicate what happens in nature when water runs over rocks through electrolysis, separating alkaline and acidic ions so the remaining drinking water is healthy, mineral-rich and closer to what nature intended.

Water ionizers hook directly up to your tap, providing an on-demand water supply that is much cheaper, more convenient and better for the environment than bottled or homemade R/O water in the long run.

Because the onboard filter(s) that all brands of water ionizers come with provide a level of filtration far inferior to R/O systems, we strongly recommend pairing a drinking water pre-filter with your water ionizer. Or, if you already have a R/O system installed you can add a remineralizer in order for the ionizer to have minerals to ionize.

You will not get the same benefits from remineralized R/O water or a bottle of mineral water as you will from filtered water run through a water ionizer. This is because the minerals have not been ionized which makes them better absorbed by the body, nor has it been microclustered, which Japanese scientists believe makes it up to six times more hydrating and detoxifying. And finally because it has not been given a negative charge which helps fight free radicals instead of creating them.

Properly filtered alkaline ionized water from a Chanson water ionizer is the solution. Stop drinking dead, acidic, mineral-leeching R/O water today. Visit us at for more information.
