Guest Substack Repost on Reverse Osmosis Water by A Midwestern Doctor
At Dr. Clark Store we get a lot of questions about water quality and which water is best. Hulda herself believed that the best source of contaminant-free water was using a large carbon filter. While this gets rid of a large amount of the most carcinogenic substances, namely the by-products of chlorination, other highly disruption molecules remain, such as a toxic form of fluoride, pharmaceuticals, and microplastics. Dr. Clark cautioned against reverse osmosis water, which has now been found to possibly contain much more nanoplastics than previously estimated, however, others have found it has nevertheless been beneficial for lowered energy potential in the body's fluids, known as zeta potential.ย
In the following excerpt from A Midwestern Doctor's substack, we get another perspective, where RO water is not far behind distilled or deionized in terms of purity, and due to its ability to increase zeta potential.ย

Reverse Osmosis Water and Zeta Potential
"One of the greatest challenges in medicine is determining how much something actually helps people, as frequently the โbenefitโ is small and takes a long time to manifest. In turn, one of the reasons I was so drawn to the zeta potential concept was that you (and the patient) would immediately notice significant differences once something was done to restore their physiologic zeta potentialย and conversely, I repeatedly saw serious complications immediately follow a disruption of oneโs zeta potential (e.g., Iโve never forgotten a patient I met when I admitted her the hospital after she sufferedย a textbook zeta potential collapseย from receiving a pneumococcal vaccine).
Zeta potential, briefly, quantifies the tendency of particles that are (colloidally) suspended in a solution to clump together or remained separated and dispersed from each other. The degree of clumping present, in turn, determines how freely a fluid will flow, soย when individuals have an impaired zeta potential, it will cause fluid stagnation throughout the body.
This fluid stagnation is often immensely consequential as almost every part of the body depends upon a healthy fluid circulation (e.g., peopleโs legs swell when fluid gets stuck in them and canโt flow back out). The consequences of an impaired zeta potential are particularly apparent in the blood, as once blood cells begin to clump together, the circulation significantly diminishes and severe conditions like blood clots or strokes can follow.
Note: I consider impaired zeta potentialย to be the root cause of many illnesses.
Zeta potential is largely determined by the balance of positive and negative charges in the body. In turn, certain agents (particularly aluminumโwhich is present in most vaccines) have very strong positive charges which in tiny concentrations cause large amounts of fluid to clump together. Because of this, we frequently observe individuals have severe consequences when exposed to a zeta potential reducing agent (e.g., many of the subtle neurological injuriesย which follow vaccination are due to microstrokes affecting the cranial nerves) and conversely, find thatย restoring the physiologic zeta potentialย is a critical component of rehabilitating these injuries.
Note: I believe many of the health โissuesโ people ascribe to consuming salt are actually due to the factย aluminumย is frequently added to salt products.
Likewise, weโve seen quite a few cases of someone having a stroke after they ate something cooked in aluminum, and Iโve read of many cases where a human or animal (e.g., a parrot) gradually developed a severe illness which went away after it stopped drinking water which was stored or cooked in aluminum. This is particularly unfortunate because almost all non-stick cookware on the market either utilizes a toxic substance (e.g., teflon) or is comprised of a thin layer of the safe non-stick coating (e.g., ceramic) lining an aluminum pan which inevitably begins to peels off and expose you to the aluminum underneath.
Note: my renewed interest in zeta potential arose after I realized the COVID-19 spike protein had a collection of positive charges which made it extremely disruptive to the physiologic zeta potential, a problem which in turn became much worse once the vaccines entered the market (e.g., I would argue this is the primary cause of the microstrokes and many of the other chronic illnesses observed following vaccination).
Typically, the kidneys are responsible for maintaining the physiologic zeta potential, which they do by excreting the most problematic positive charges (e.g., aluminum) while retaining the beneficial negative charges. In turn, since renal function declines with age, zeta potential worsens as well, and I believe many of the complications of aging are ultimately a result of a gradual loss of the physiologic zeta potential.
Note: I adopted the initial RO unit I used after I found out the local hospital was using it for patients with kidney failure because it was the only filtration system which effectively removed aluminum from water they used for dialysis (toxic levels of aluminum are a recurring issue for these patients).
A variety of approaches exist to improve zeta potential, but most of them essentially boil down to avoiding the problematic positive charges (e.g., reducing your aluminum exposure) and adding beneficial negative charges to the body. In turn, I have found that many of the holistic therapies which have a wide range of positive benefits attributed to them (e.g., Earthing)ย all share the common thread of improving zeta potential.
Drinking deionized water forms a critical part of the zeta potential protocols because it eliminates many of the positive charges from the water you ingest which the kidneys would otherwise need to eventually eliminate. This is particularly important because the kidneys function much more efficiently when they have a low workload on them (i.e., not having to work against as high of a positive ion concentration gradient in the blood).
In short, all of the pioneers of treating zeta potential found that while drinking deionized water or consuming the correct negative charges helped, both typically had to be done together for anyone with a significant zeta potential impairment. This in turn has matched my own clinical and personal experience (as I am more sensitive to zeta potential disruptionsโe.g., Iโve experienced minor microstrokes from eating food that was stored in aluminum).
Note: Iโve had quite a few older patients who switched from drinking RO water to well water and then developed a variety of unusual illnesses I was ultimately able to attribute to a loss of zeta potential (as well water contains a significant amount of positively charged minerals).
Water Containers
The specific thing which prompted me to write this article has been the recent health fad of aluminum containing bottled water, which I believe was doneย in response to peopleย being concerned about plastic from both a health and environmental standpoint and it being possible to make more trendy looking โluxuryโ water bottles people would buy purely based on their appearance.

Note: technologies the industry wants to adopt are often initially marketed as specialty luxury products. For example, soy (which is often anything but healthy) was introduced to America first by having it be strategically placed in health food cook books to generate a โgrass rootsโ demand for it.
I find this push we are seeing for aluminum containers (many celebrities and companies are now endorsing it) to be immensely frustrating as its proponents are frequently only seeing half of the picture.
For instance, while it is true that aluminum being possible to recycle significantly lowers its environmental footprint, this simultaneously ignores the fact that the the initial production of aluminumย is incredibly energy intensive and environmentally destructive. Likewise, while it is acknowledged that a โmetallic tasteโ (of leached aluminum) is a downside of using aluminum bottles,ย those some people simultaneously argue aluminum cans are completely safe.
While in general it is still quite feasible to avoid these products, I find the proliferation of these products to be particularly frustrating in areas with captive markets where you need access to clean water. For example, in many airports (particularly those in the more progressive areas) all the bottled water is gradually being switched to aluminum ones, and likewise certain airlines (e.g., Southwest) now exclusively offer water to passengers which was stored in aluminum cans.
Note: the original rationale for banning liquids from airports arose from a team of terroristsย who allegedly plottedย to bring liquid materials with them that were necessary to manufacture a solid bomb on the plane. Since actually making the alleged explosive on a planeย was almost impossible, this led me to believe there was an entirely different reason for banning the liquids (e.g., to have another activity that increased compliance with the war on terror, increasing drink sales in the airport or preventing passengers from making messes on the planes). Sadly, this lie went unchallenged, and almost twenty years later, liquids being banned from airports has been normalized to the point almost no one questions it."

FAQs
- Membrane Degradation & Shedding:ย RO membranes are typically made fromย polyamide plastic. As these polymer-based membranes age, become fouled, or are subjected to high pressure and chemical cleaning, they can physically break down and release tiny plastic fragments directly into the purified water (the permeate).
- System Components:ย The "purified" water travels through multiple plastic housings, connectors, andย polyethylene tubingย before reaching your glass. Friction and mechanical stress on these plastic parts can cause them to leach or shed particles into the already-filtered water.
- Storage Tank Leaching:ย Most RO systems store water in a pressurized tank with aย butyl rubber or plastic bladder. Since RO water is "hungry" (it has been stripped of minerals), it is more aggressive and can leach materials from the storage tank walls and internal components over time.
- Manufacturing Imperfections:ย Studies suggest that minute imperfections or "pinholes" in the membrane surface can allow sub-micron particles to bypass the nominal pore size
