Is Reverse Osmosis water good (or bad) for your health?

Given that I’m writing a book about water, accepting an offer to review a home water filter made sense. But now it’s on my kitchen counter, I’m not sure if I want to use it. My reservation is this — how pure is too pure?
Reverse osmosis (RO) is typically used to desalinate salt water or seawater into drinking water. For hundreds if not thousands of years, desalination was achieved by heating water and condensing the steam (distillation): great on a small scale, if you’re a sailor using the sun to produce a cup of water, but terribly energy expensive on a large scale. RO was a game changer when it became commercially available in the mid 20th century. By using an ultrafine membrane to push the water through, it leaves salt and impurities on one side and pure water on the other.

  1. When it comes to water you don't have a lot of choice but to use RO when the water suppliers now add fluoride.  I have been drinking RO first pass water for the last year or so.  The conductivity is approx. 3.0uS/cm which is slightly lower than rain water collection.  My health has improved dramatically as I no longer have severe joint pain in my elbows, knees & hips and I managed to drop 10kg when my adrenal system started to function better.  I changed my water type after I had developed a thyroid problem from drinking the fluoridated water supply so I can only endorse the drinking of RO water if your body is unable to remove toxins from your system naturally.  I normally add my water to tea or coffee and do not generally drink it alone so maybe I am not a good candidate to indicate if the water is bad for you.  I would drink RO water any day over municipal water supplies.  I am an analytical chemist with 30 years of water industry experience in case you might think I am one of those conspiracy crazy people.

  2. Good points raised, although some suspect results from testing. Generally agree with these points. However it also looks like a baldly obvious endorsement of the mentioned reverse osmosis system, tainting your conclusions. Have you considered an advertising career?

  4. I also wrote a book about water and started out 10 years ago studying the water treatment options. The problem with filtration methods is that it's never a completed proces, if water quality is your aim. Which it is, when it is for (daily) consumption. The answer to your question therefore is too long, but I did write a Blog about your question (In Dutch ;) https://nieuwwaterwinkel.nl/de-waarheid-over-omgekeerde-osmose/

  5. Hi. The problem is that you do not want to purify and desalinate water with simpler and less expensive solutions.
