Reverse osmosis (RO) is a water purification technology that uses a semi permeable membrane to remove ions, molecules, and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure.
Reverse osmosis can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water such as fluoride.
The result is you get very pure water. Unfortunately this water becomes “Dead Water” lacking the alkaline minerals needed by your body and even worse can leach it from you.
We understand that your RO salesman has already heard this complaint and has an answer ready for you. He will try to sell you a ‘remineralising’ cartridge’ to add the minerals you just paid to have removed, back in. Our report on remineralisers follows, and we’ll help you steer clear of the majority of duds sold to people like you.
But let’s try for another ‘brownie point’ in your decision. Just WHY isn’t pure water good for you?
We all agree that we require an adequate supply of electrolytes.
- Removes virtually all fluoride and chlorine (IF unit is properly maintained and filters changed regularly.
- Removes virtually all bacteria, micro-organisms and tiny germs
- Removes Lead and Heavy Metals.(Note: it’ s almost impossible to locate any test data of RO systems beyond initial (new) use tests. Cheap RO units use Chinese prefilters that quickly degrade the RO membrane.)
- Leaves water demineralized (lacking any minerals)
- Expensive and difficult to replace filters
- Water often acidic
- Often sold with maintenance contract becasue it is too hard to maintain without specialised knowledge.
- Wastes at least 4 times the water it produces (sometimes as much 10 times)
- Often inefficient when chlorine affects membrane ~ especially on cheap Asian systems.
“The potential for adverse health effects from long-term consumption of demineralized water is of interest not only in countries lacking adequate fresh water but also in countries where some types of home water treatment systems
are widely used or where some types of bottled water are consumed.”

They are in your blood, urine and body fluids. Maintaining the right balance of electrolytes helps your body’s blood chemistry, muscle action, and other processes.
They are there because we need them and we need them because we have evolved over many thousands of years to utilize their health benefits. Our ‘Paleo’ metabolism is the same as it was thousands of years ago, our ‘paleo’ food needs are same, and our ‘paleo’ water needs are the same.
Dr. Lynda Frassetto (UC) has published some excellent work showing how our paleo metabolic template still operates – and she highlights the problems we have when we try to go against its needs.
* For magnesium, a minimum of 10 mg/l (Novikov et al. 1983; Rubenowitz et al. 2000) and an optimum of about 20-30 mg/l (Durlach et al. 1989; Kozisek 1992);
* For calcium, a minimum of 20 mg/l (Novikov et al. 1983) and an optimum of about 50 (40-80) mg/l (Rakhmanin et al. 1990; Kozisek 1992);
“not only does completely demineralized water (distillate) have unsatisfactory organoleptic properties, but it also has a definite adverse influence on the animal and human organism.”

We have heard many RO vendors claim that the body cannot absorb inorganic minerals. It’s their way of skirting the issue that they remove all minerals. They argue that the removed minerals are inorganic so they wouldn’t be absorbed anyway. This is simply untrue. We absorb ‘inorganic’ minerals every day.
Your body can take up anywhere from 6% to 30% of its daily requirement of essential minerals from tap water. We live in a world where our soil is becoming devoid of nutrients as we over-farm and over-fertilize it. Our diets are far from healthy, so in our opinion it is very important to your long term health that you ingest calcium and magnesium from drinking water.
This is certainly supported by the latest news of ‘hundreds of Israelis’ actually dying from drinking their nationally supplied nutrient-stripped water.
So we’re going to be very, very careful in our claim that reverse osmosis may be so unhealthy that it may even kill you.
In a previous post we introduced the Israeli scientific study directly linking RO water to hundreds of CVD deaths every year. The report is the only one we’ve seen, and so one can be forgiven for being cynical. But, let’s score ourselves on this. If we can show you five good reasons you absolutely should NOT drink ‘pure’ RO water… then we assume you have accepted what we said, and we will be happy to help you make the change to healthy water.
Let’s look at the next study we’ve been privy to. This is from the World Health Organisation. (download it here).
“The composition of water varies widely with local geological conditions. Neither groundwater nor surface water has ever been chemically pure H2O, since water contains small amounts of gases, minerals and organic matter of natural origin. The total concentrations of substances dissolved in fresh water considered to be of good quality can be hundreds of mg/L.”
Yes, there is a Water filter that Removes Heavy Metals, Toxins, Bacteria, Chlorine, Chloramines and Fluoride (and has been tested for the life of the filter) plus removes hundreds more toxins out of our water. It maintains essential levels of calcium, magnesium, and trace minerals for perfect pH balance. The UltraStream outperforms electric ionizers that can cost thousands more and infuses the filtered water with molecular hydrogen. Over 700 scientific studies validate health benefits from infused hydrogen!
