The popularity of reverse osmosis water (R.O. water) has steadily grown since it was first introduced as a home water purification system in the 1970s.
In addition, the type of treated water most often used by bottled water companies is reverse osmosis water.
The R.O. water purification method involves forcing water through a semi-permeable membrane, which filters out a select number of water contaminants, depending on the size of the contaminants.
In general, if the contaminants are larger in size than water molecules, those contaminants will be filtered out. If the contaminants are smaller in size, they will remain in the drinking water.
Many years ago I drank reverse osmosis water almost exclusively, believing that it was the best drinking water. However, since then I have discovered (through personal experience and research) that the health disadvantages outweigh the advantages.
As far as I can tell, there is only one health advantage R.O. water has over tap water—and that is that the R.O. system does remove some unhealthy contaminants.
A good R.O. system can remove contaminants such as arsenic, nitrates, sodium, copper and lead, some organic chemicals, and the municipal additive fluoride.
You might be interested to know that reverse osmosis was actually developed as a water treatment method over 40 years ago. The process was used primarily to de-salinate water.
The following are three of the main disadvantages of drinking R.O. water:
1. The water is demineralized. Since most mineral particles (including sodium, calcium, magnesium, magnesium, and iron) are larger than water molecules, they are removed by the semi-permeable membrane of the R.O. system.
Even though you may find some contradictory information online about the health benefits of reverse osmosis water, I am convinced that drinking de-mineralized water is not healthy.
The World Health Organization conducted a study that revealed some of the health risks associated with drinking demineralized water. Just a few of the risks include gastrointestinal problems, bone density issues, joint conditions, and cardiovascular disease. See reference below to review the WHO study online.
Removing the naturally occurring minerals also leaves the water tasteless. Many people thus have to add liquid minerals to their R.O. water to improve the taste.
2. The drinking water is acidic. One of the primary reasons R.O. water is unhealthy is because removing the minerals makes the water acidic (often well below 7.0 pH). Drinking acidic water will not help maintain a healthy pH balance in the blood, which should be slightly alkaline.
In the natural health and medical communities, acidosis in the body is considered an underlying cause of most degenerative diseases. In fact, in 1931, Dr. Otto Warburg won the Nobel Prize for discovering the cause of cancer. In essence, he said it was caused by a lack of cellular oxygenation due to acidosis in the body.
Medical research has also determined that drinking acidic water (as well as other acidic beverages) will often cause a leaching of essential minerals, such as calcium and magnesium, from the body, especially from the bones and teeth, in order to neutralize the acidity.
3. Some critical contaminants are not removed. While reverse osmosis is effective for removing a variety of contaminants in water, it does NOT remove volatile organic chemical (VOCs), chlorine and chloramines, pharmaceuticals, and a host of other synthetic chemicals found in municipal water.
If you currently have a reverse osmosis system and are not ready to give it up, I recommend adding liquid ionic minerals, such as Trace Minerals Ionic Tonic, to your R.O. drinking water.
However, doing so will not be as beneficial as drinking water that contains minerals naturally, but it will help somewhat with the acid-alkaline balance in the body.

If your health is a top priority and you don’t want to be drinking de-mineralized water, invest in a water filter that best suits your needs. See our water filter reviews page for more information.
The health disadvantages of drinking R.O. water are similar to those of drinking distilled water since they are both demineralized. Read more here about the health effects of drinking distilled water.
