Bottom Line

Evidence-Based Take:

Quinton water is an interesting historical intervention with a devoted following but limited modern clinical research. The concept, that seawater minerals in proper proportions can support cellular function, has mechanistic plausibility, but high-quality RCTs are lacking.

What the Evidence Shows:

  • Trace mineral supplementation is well-established as beneficial when deficient
  • Seawater mineral profiles are similar to human extracellular fluid
  • Historical clinical use was extensive (early 1900s France)
  • Modern research is limited, mostly observational or mechanistic

Honest Assessment:

If you're mineral-deficient (common with modern diets and depleted soils), Quinton water provides a broad-spectrum mineral source. The isotonic form is essentially a fancy electrolyte supplement. The claims about "cellular terrain" and "bioavailable minerals" are plausible but not rigorously proven. It's expensive compared to regular mineral supplements.

Key insight: René Quinton successfully used diluted seawater to treat thousands of patients in early 20th century France. While medicine has advanced significantly, the principle of trace mineral importance remains valid.

Science

What Is Quinton Water?

Quinton water (also called Quinton plasma or marine plasma) is filtered seawater harvested from specific ocean vortex zones and cold-sterilized to preserve mineral content. It was developed by French physiologist René Quinton (1866-1925).

The Quinton Hypothesis:

Quinton observed that the mineral composition of seawater closely resembles human blood plasma and extracellular fluid. He theorized that replenishing this "internal ocean" could restore cellular health.

Mineral Composition:

ElementFunction
Magnesium300+ enzymatic reactions
PotassiumNerve/muscle function
CalciumBones, signaling
ZincImmune function, enzymes
SeleniumAntioxidant, thyroid
70+ trace mineralsVarious cofactor roles

Two Forms:

1. Isotonic - Diluted to 9g/L salinity (matches body fluids) - Gentle, for daily use - Hydration and maintenance

2. Hypertonic - Full-strength ocean plasma (~33g/L) - More concentrated minerals - Short-term or specific protocols

Historical Context:

In early 1900s France, Quinton opened free "marine dispensaries" treating patients with diluted seawater via injection and oral administration. He documented thousands of cases, particularly in malnourished infants and patients with skin conditions. His work was mainstream medicine in France for decades.

Why It Might Work:

  • Modern diets are often mineral-depleted
  • Soil depletion reduces mineral content in foods
  • Trace minerals serve as enzyme cofactors
  • Proper mineral ratios may matter for absorption
  • The body evolved in a mineral-rich environment

Rene Quinton's principle that life carries the ocean within

Slovak opens with Rene Quinton's foundational insight that the only way life could have left the ocean was to take the ocean with it, and that maintaining the ocean's mineral composition in the body is essential because seawater is the only known solution of the full periodic table in the universe.

"You must respect what Rene Cantone said, because it's so simple and so brilliant. The only way life could have left the ocean was to take the ocean with it. And you did. And you're supposed to keep creating the conditions of the ocean, its composition, its balance of the periodic table of the elements, because the ocean is the only known solution of the periodic table of the elements in the known universe."

Slovak's personal recovery from myocarditis using Quinton

Slovak shares how he recovered from severe spike protein-related myocarditis that left him unable to walk 80 yards, using Quinton isotonic daily to regulate his terrain alongside grounding, red light therapy, and colostrum.

"It's interesting because that's what I like about Dr. Shade who runs that company. He uses some of the advanced delivery mechanisms, like the lipophilic delivery mechanisms. But then he's also got this knowledge of ancient Chinese medicine. And so he kind of blends that ancient stuff with some advanced delivery mechanisms. And I don't know, I feel like I really felt as though I could really push myself from a cardiovascular standpoint after using this stuff. I didn't wind up making it part of my protocol, but it's a pretty interesting supplement. When he saw me at Asprey's biohacking conferences, I joined the Quicksilver booth to talk about Kintone Marine Plasma. He goes, what have you been doing since the last time I saw you? You can actually walk fast again. And I'm going, I'm taking your performance cardio. The cardio perform. Yeah, interesting. Now, you're still using the hydrogen tablets too, right? Oh, that's a staple. That's like almost close to breathing. Okay. Did you see the study? Because I literally just tweeted it out a few days ago and I was like, oh, I'm having Robert on the podcast. I actually asked him about this. It was a hydrogen rich water study, you know, the same as you get when you have these tablets to the water. And the title was hydrogen rich water consumption positively affects muscle performance, lactate response, and alleviates delayed onset of muscle soreness after resistance training. And granted, a lot of these journalist strength conditioning studies, they're not that huge. I think this was like a dozen men or so. But really significant improvement in not only muscle function, but then reduced lactic acid formation, and then way lower onset of muscle soreness. And I don't know how far before the workout that they took this stuff, but you and I covered this last time. Unlike a lot of antioxidants like synthetic vitamin C or synthetic vitamin E, the hydrogen doesn't blunt the hormetic response to the workouts like a selective antioxidant. And so I feel like, you know, because I'm doing like a morning workout a lot of the time, that by starting off my day with this giant glass of the hydrogen, I'm probably getting some of those effects. But this is the first time I've seen a performance study like this. Have you seen that? Oh, yeah, yeah. Because you asked me to address it, and I took a deep dive into it with both Tyler and Alex, who know this business backward and forward. And they made some comments. Yes, this is very good. But, you know, even though like muscle soreness and so on is actually better in hydrogen hydrotherapy, which is a new coming direction for hydrogen."

How phytoplankton and zooplankton create Quinton's source

Slovak describes the oceanic ecology behind Quinton harvesting, explaining how zooplankton at 300 feet ascends into phytoplankton blooms spanning hundreds of kilometers at the surface, creating the mineral-rich biological matrix from which Quinton is extracted.

"Phytoplankton is on the surface in the first 100 feet, and zooplankton hangs out at 300 feet below the phytoplankton and ascends periodically into the phytoplankton and consumes it just like a cow goes out to pasture."

Quinton's complexity versus simple mineral supplements

Slovak explains that Quinton is far more complex than simple mineral supplements, containing over 100 micronutrients including natural anti-fungals, anti-bacterials, RNA fragments, and DNA from the living ocean, which are more delicate than the mineral components.

"Cantone is much more complex. So it has like 100 plus micronutrients in it. Anti-fungals, anti-bac, it's natural from the sea. So it's got this plethora of micronutrients that have many kinds of functions. It's got RNA fragments, DNA, et cetera. Very, very complex, not just the minerals."

Quinton sea minerals for remineralizing purified water

Storey recommends Quinton Sea Mineral Solution as his favorite method to remineralize reverse osmosis purified water, noting it is available through Water and Wellness alongside countertop RO systems.

"Let's now cover countertop purification. My favorite reverse osmosis countertop system is made by a company called Aquatrue, available from the site waterandwellness.com, who incidentally also sell Quinton Sea Mineral Solution, which is my favorite way to remineralize purified water."

Why mineral-stripped water needs replenishment

Storey explains that the body is approximately 70-90% water and that blood, lymphatic fluid, and virtually every liquid in the body are made primarily of water, establishing why mineral-rich water matters for cellular health.

"Your body and brain are made of approximately 70 to 90 percent water. On a molecular basis, your body's about 99 percent water."

The fish tank analogy for body water quality

Storey uses the fish tank analogy to illustrate why the quality of water in your body matters more than what you put into it, arguing that the terrain of your internal water environment determines health outcomes.

"You can think of your body as a fish tank, right? What's more important in a fish tank? The food that you pour into it or the quality and cleanliness of the water. The environment or terrain of the water in the tank makes the difference between life and death."

How Quinton is harvested from oceanic plankton blooms

Slovak describes how Quinton is harvested from massive plankton bloom assemblages in the ocean, where phytoplankton lives near the surface in the first 50 feet and zooplankton ascends from 300 feet below to consume it, creating the mineral-rich solution.

"Well, let me finish. So there's assemblages in the ocean, huge, hundreds of kilometers across of phytoplankton that's near the surface within the first probably 50 feet because that's the zone of light and phytoplankton needs light. But in nature, in oceanographic nature, hundreds of feet below, there's also zooplankton."

Rene Quinton's 1904 canine blood transfusion proof

Slovak recounts Rene Quinton's landmark 1904 experiment in which he completely transfused the blood of six canines with isotonic seawater, demonstrating seawater's biocompatibility with mammalian physiology.

"Well, let me finish. So there's assemblages in the ocean, huge, hundreds of kilometers across of phytoplankton that's near the surface within the first probably 50 feet because that's the zone of light and phytoplankton needs light. But in nature, in oceanographic nature, hundreds of feet below, there's also zooplankton. And zooplankton is like krill is a zooplankton. Copiopods are zooplankton. They're microscopic. I don't know. You could call them microscopic shrimp if you like. and very much like cows at a farm going to pasture, eating grass and coming back to the ranch, the zooplankton ascend upward through those 300 feet, say, and consume the phytoplankton. In the consuming of the phytoplankton, there is an incredible, we will call it biocynotic event, meaning it's a bioreactor of unimaginable biochemical reactions that involve not only all the elements of the periodic table in the water, but all the things that are being produced, the fluids, the chemicals, the phytochemicals, et cetera, by both the phytoplankton and the zooplankton. That goes on between those two layers, the phytoplankton on top, the zooplankton on 300 feet below. And in the center, it is actually referred to as the zone of biocenosis. And that is the birthplace of Kintone. So if you just say, well, Robert, I don't want to get my seawater from there. I have an island off the coast of the Philippines. I will tell you the value of all the periodic table that you would consume from that ocean are incredible. Use it, do it, but it won't do all the things that plankton bloom-derived seawater is able to do. And what is that? Well, for 124 years now, Cantone marine plasma in those little glass ampoules has been perhaps we can call it one of the top three or four medicines, not just nutrients, of all time. It was in the European Physician's Desk reference from about 1930 to 1999 as a medicine, right along with whatever penicillin and all the other pharmaceutical medicines. It was indistinguishable from those other things because of what it did. From when the time that René Cantón discovered it or produced it in 1897, and then to prove to himself this was the most life-combatible fluid known, the most famous thing he probably did was to transfuse the whole blood of six dogs in 2004. You mean like an intravenous administration of Keaton? Yes, but a full replacement, meaning replace as much blood as you can get out of the dog. It wasn't a cakewalk for the dog. Jesus, poor dogs. Jeez. Yeah. Okay. So he did this, but the dogs survived and thrived. And several of the dogs that weren't healthy dogs became healthy. And he wrote a 500-page treatise that describes this event in minute-by-minute detail. And this has been produced several other times in history that this is beyond belief. So he did it. Now, just shortly after 2004, Europe was raked with multiple pandemics. Already, cholera was in play from the 1800s, tuberculosis, typhoid, gastroenteritis, here we go, syphilis, influenza, etc. All the diseases of the early 1900s that were killing approximately 50,000 people per month. So what happened was there were no pharmaceuticals then. There were potions, homeopathics, herbal elixirs, etc., but no real medicines real medicines so when john jericho the preeminent physiologist of the time was part of this solution of getting of overcoming the pandemics he asked renee canton what if what about your stuff and they said well's do it. Let's take sick people and let's administer Quintone in a variety of ways. We don't have the time to get into it, but they did. And it became a worldwide study. And Europe and Northern Africa set up 69, they were called in French marine dispensaries, but they were places where the sick came in to have only canton administration. They were called in French marine dispensaries, but they were places where the sick came in to have only Canton administered to them. They administered it by subcutaneous injection. They administered peritoneal injection. They administered it orally. They administered it rectally. They did everything. Consuming, drinking it, Depending upon the affliction and the disease, they had figured out the best way to administer it. And it became legend. By the time René Cantón passed away in 1925, it had saved Europe from virtually all of the pandemics. and he was revered, you know, like something like, I can't remember, 150,000 people show up at his funeral and there's statues all over Europe acknowledging Rene Cantone. So this continued on. It was still in this book called The Vidal. And I have a copy of the book. You know, it's like a three-inch thick book that has Quinton as a cure. What's the book called the vidal and i have a copy of the book you know it's like a three inch thick book that has quinton as a cure what's the book called again it's called the vidal the vidal i-d-a-l it's the it's the physician's desk reference of france but but in those early days france was so ahead of everybody in medicine it was the physician's's desk reference of Europe. I have a copy. I have copies of all the entries in there and what it did and what it was doing. In 1934, really the first medicine really that was serious came out and that was called penicillin. And that took some of the thunder away from Kintone because it was much easier to use. And you can imagine in those days making a sterile solution that could be injected out of seawater without, and this is the key everyone must know, Kintone is never heated. It's never taken above room temperature. It's all sterilized and made apyrogenic for pyrogen removal by very specialized microfiltration. What's pyrogen removal? Pyrogen are fragments of bacteria that are the activators for the body to raise its temperature, to react and beginning to build a defense against microbial diseases. So pyrogen, they're really polysaccharides and the pyrogen activates things in the body."

Why sea salt can never become seawater again

Slovak explains that the proportions of elements in human extracellular fluid match those in seawater, and that once you remove water from sea salt, you can never reconstitute it back to true seawater, which is why liquid marine plasma is irreplaceable.

"That's the magic. That's why sea salt, as beneficial as it can be, it never can become seawater. Once you remove water, and water is the magic, you never can reconstitute it."

Percutaneous hydrotomy for spinal disc healing

Slovak describes percutaneous hydrotomy, a procedure taught in Nice, France, where an octopus-like array of subcutaneous needles delivers Quinton isotonic around the spine by gravity to rehydrate and heal damaged discs.

"And what they do is they have like an octopus. Imagine an octopus of subcutaneous needles of, say, eight of them, all connected with a manifold of plastic tubes that lead to a bottle of Kintone isotonic. Those little needles are inserted around, just subcutaneously, into and around the spine. And they just allow the Kintone to flow by gravity to rehydrate the spine and heal."

Why heating Quinton destroys its therapeutic properties

Slovak explains that while heated Quinton retains its minerals and trace elements, the heat destroys its full biological complexity including RNA fragments and organocomplexed components that make it therapeutically unique.

"If you heat Kintone, will it have beneficial minerals and trace elements? Absolutely. Will it have the same potency as a living extract? No."
