Quinton water : the rejuvenating marine serum

Marina plasma, also called Quinton water, Quinton serum or Quinton plasma, is actually… seawater. This famous water whose health benefits were praised by Hipocrates, a leading figure of ancient Greek medicine, as well as Plato, another great Greek philosopher, several centuries ago.

However, it is not ordinary seawater. Indeed, Quinton water is produced following a rigorous process of extraction and filtration, allowing the precious liquid to conserve all its nutrional properties.

To produce Quinton plasma, a sample of seawater is taken in a specific zone, at sea. This sample is then microfiltered in order to eliminate all impurities, all while conserving as many minerals as possible, in ideal proportions.

Due to its many benefits, Quinton water was used in the past to treat various health problems and to treat nutritional deficiencies. Even though today it has been replaced by more conventional methods and is often considered, unfortunately, as a sort of ‘’grandmother remedy’’, it can still be gotten in different forms, to be consumed over a period of a few weeks.

Quinton water can be hypertonic (the seawater is pure) or isotonic (the seawater is mixed with weakly mineralised spring water, with the proportions being one volume of seawater to two volumes of freshwater).

Who is René Quinton?

René Quinton
René Quinton in 1908

René Quinton, born in 1866 from the union of Marie Amyot and Paul Quinton, is the French naturalist, physiologist and biologist who discovered and developed the serum that bears his name, Quinton water. A forgotten hero today, he was nevertheless a recognized personality in France and even in the world during his lifetime.

At the end of the 19th century, René Quinton took a keen interest in the marine environment and his research led him to the conclusion that seawater intake could be beneficial to human health.

He first discovers that seawater has the same chemical composition as our blood plasma, except that it is more concentrated in salt. According to him, the sodium chloride content in seawater has varied over the millennia, going from 7 to 8g per litre in the primary oceans to 33g per litre today.

Based on this analysis and based on the observation that animal life in a cellular state appeared at the bottom of the oceans, and that man must therefore have kept the stigmata of his marine origins, René Quinton postulated that seawater, brought back to its original salt concentration, can help rebuild damaged cells in the body.

He conducts several experiments to prove his theory, one of which has gone down in history. In 1897, at the Collège de France, in the laboratory of the famous physiologist and member of the Académie de Médecine Étienne-Jules Marey, his mentor, he bleeds dry a dog weighing 10 kilos and already in poor health, going by the sweet name of “Sodium”. During this exsanguino-transfusion, he replaces a large part of the blood of the dying dog (425g) with sea water brought to isotonicity (532ml), at a temperature of 23°C. Against all odds, the dog survives and, after a few days, regains exceptional vitality. Sodium went on to live another 5 years after the injection, before dying from a collision with a car.

His observations, research and experiments led him to develop a theory called the “law of general constancy”, which synthesises several laws he had previously stated:

  • the law of marine constancy (“animal life has been maintained in an environment identical to that of its origins”);
  • the law of thermal constancy (“animal life tends to maintain a constant temperature below 44 degrees Celsius, close to that of our origins”);
  • the law of osmotic constancy (“the identity of the marine environment and the interior environment enables osmotic balance and the maintenance of life”).

In 1904, he published his reference book L’eau de mer, an organic medium prefaced by Prof. Marey.

In 1905, he opened his own laboratory in which he produced Quinton plasma. The product is made commercially available.

Several successful experiments in Paris hospitals, including cures in so-called “hopeless” cases, confirmed the therapeutic efficacy of marine plasma, which René Quinton administered first by intravenous injection, then by subcutaneous injection.

The first marine dispensary opened in Paris on March 26, 1907. The success was such – more than 300 injections daily – that it was soon imitated all around France. Doctor Jean Jarricot, a renowned general practitioner and homeopath, was the head of the Lyon dispensary, the last to be opened, between 1913 and 1938.

These health establishments treated thousands of patients free of charge. They dealt with health scourges such as cholera, tuberculosis, malnutrition and gastroenteritis. Infants suffering from lactose intolerance, developmental delay or atherpsy gained weight dramatically under the effect of marine therapy. Quinton’s methods were even adopted outside French borders – to Belgium, England, the United States, and to Egypt, where the physiologist was called upon to stem an epidemic of infant cholera.

Despite some detractors who crticised him for the lack of scientific basis for his therapeutic method, Quinton’s fame was at its highest when he was called upon for the war effort in 1914. Wounded on several occasions, he demonstrated great aptitude for combat and ended up becoming colonel of artillery in 1918. After the First World War, his works gradually fell into oblivion, eclipsed in particular by those of Louis Pasteur, of whom he was a contemporary. In addition, René Quinton began to dedicate himself entirely to his other passion, aviation, contributing to the development of a new discipline: gliding, or glider.

He died in 1925, at the age of 58. He is honoured with a state funeral in Paris in the presence of important personalities. A statue bearing his effigy was erected in 1931 in his native town of Chaumes-en-Brie, in Seine-et-Marne.

For a more complete biography, I recommend that you watch this video from Quinton Laboratories.

This video by the writer Pierre Lance, which looks back on the life of the ‘’French Darwin’’, is also very interesting.

What is the similarity between Quinton plasma and blood plasma?

Quinton water is also called marine plasma in reference to the similarity to blood plasma, which is used for the transport of blood cells (red blood cells, leukocytes and platelets) and interstitial fluid, which facilitates nutrient exchange between cells and capillaries blood.

René Quinton had indeed noted many similarities between seawater and our internal environment, even comparing the aging body to an aquarium whose water is gradually “polluted”. By changing the water in the aquarium, the fish regain vitality; Likewise, by drinking seawater, the body’s cells regenerate themselves since they are bathed in a higher-quality extracellular fluid.

This affinity between the two liquids is actually at the level of their chemical and biological composition, since their mineral concentration is identical. The only difference is in the amount of salt, which is much higher in seawater than in blood plasma. For seawater reduced to isotonicity, however, this rate is the same.

Quinton had been able to verify this analogy through an astonishing experiment. He had put white blood cells into isotonic seawater. In an artificial environment, they are considered too fragile to survive. Here, however, the white blood cells stayed alive, with completely normal mobility. This tolerance of our immune cells to Quinton Isotonic® was also confirmed in 2003, using modern means (dark field microscope) by WHO biochemist Marie José Stelling…

What is the composition of Quinton water?

Quinton water is composed of marine water, rich in minerals: aluminum, silver, bromine, cesium, calcium, copper, iodine, lithium, magnesium, manganese, potassium, silicon, sodium, zinc, etc.

It is developed according to a well-defined protocol. René Quinton had indeed carried out research to determine the areas to be favoured for collecting seawater in order to guarantee its purity and richness.

Thus, it is collected in calm weather off the coast, at a depth of about 30 meters, in the centre of what are called “planktonic vortices”. These are eddies of water generated by sea currents, favourable to the proliferation of phytoplankton. These microalgae need light, CO2 and mineral salts to develop. They will thus absorb marine minerals and make them bioavailable, i.e. assimilable by the body.

In France, seawater is collected in the Bay of Biscay, off Arcachon, as well as in Brittany, off Saint Malo. In Spain, collection takes place, among others, off the islands of Ibiza and Formentera.

The collected water is first filtered at 0.5 microns directly on the boat and its temperature is stabilised, at around 4°C. It is then stored in a container certified for food contact and transported in a refrigerated truck to the laboratory.  It is then sterilized in a “clean room” in accordance with the requirements of the European Pharmacopoeia (the protocol is the same for the production of a medicine), by cold microfiltration at 0.22 microns, before being packaged in an ampoule or in bottle. Important detail: it does not go through any contact with metal or rise in temperature.

Throughout the process, quality analyses are carried out to verify its composition and to make sure that it doesn’t contain bacteria, traces of pollutants such as hydrocarbons, plastic microparticles, pesticides and herbicides, or heavy metals.

It should be noted that the name “Quinton” is today a trademark registered by the Quinton International Laboratories, located in Alicante, Spain and specialized in the production of seawater-based food supplements. The other companies that market the product can therefore only use the term “Quinton method”.

Below a video showing the stages of production of the Quinton Hypertonic® and the Quinton Isotonic® in the Quinton Laboratories.


There are two types of Quinton water: hypertonic and isotonic.


Hypertonic Quinton water is the most ‘’pure’’ of the two. It is seawater in its original form, without any dilution. It is very rich in minerals and trace elements, and has quite a strong salt taste.

Volume of seawater to fresh water Amount of salt per cl.
Hypertonic Quinton 1 to 0 0.35g
Isotonic Quinton 1 to 2, to 1 to 3 0.11 to 0.087g

Due to its high mineral concentration, it is often used first during a detoxing cleanse, as a “shock treatment”. For how long? In general, we recommend a duration of 21 days: this allows to stimulate the organs responsible for the elimination of waste (kidneys, liver, intestines) and to release cellular energy in order to prepare the body for the revitalisation provided by the marine plasma.

Hypertonic Quinton water is favoured in the treatment of certain ailments such as allergic rhinitis (it can be found in nose sprays), overstrain, mental or physical exhaustion, demineralisation… It is also effective in rebalancing acid-base, because it helps regulate gastric and intestinal pH, thus reducing health problems caused by acidity in the body – even if acidity is not the only cause!

It is also popular among athletes, who consume it in a drinkable ampoule before intense physical activity, and even afterwards to ease recovery.

However, it is recommended to drink it in small quantities. Indeed, its salt content being higher than that of our blood, our organism is forced to compensate for this excess. In addition, there are certain contraindications associated with it.


As for isotonic Quinton, this is seawater diluted with, preferably, high-quality spring water. It is very close to blood plasma since its salt concentration is only 9 grams per litre instead of the 33 grams contained in a litre of seawater. Different spring waters, weakly mineralised, can be used for dilution. In the Quinton CSBS, for example, we find spring water from Rosée de la Reine.

The isotonic formula is suitable for everyone. It is preferable for long-term use, to rebalance and revitalise the body, stimulate the immune system, and promote detoxification. Its long-term use will help to fight skin problems such as eczema and psoriasis, infections like colds and sinusitis, temporary fatigue, and digestion problems. It also helps to rehydrate the body and to compensate for deficiencies in minerals or trace elements. Finally, it is of course used in addition to hypertonic Quinton: some therapists advise to alternate between the two.


Making your own isotonic quinton is a much less costly solution than buying it directly. Here is how to go about it in just a few steps.

First of all, get some hypertonic marine plasma.

Then choose a spring water or a good-quality mineral water, weakly mineralised, with a dry residue under 100mg/L. Some examples: Volvic, Mont Roucous, Mont Calm, or Rosée de la Reine. Whatever you do, avoid distilled water, it has a destructive effect on the marine serum!

Finally, when diluting, respect the following ratio: ⅓ hypertonic marine plasma to ⅔ spring water.


Quinton water possesses multiple interesting properties. Let’s have a closer look at its mineral and trace element concentration.

Composition of sea salt

The minerals contained in Quinton’s plasma are said to be “bioavailable”. Thanks to the action of marine microorganisms such as phytoplankton (plant plankton), they are transformed into directly assimilable elements, which thus easily cross the intestinal membrane. According to researchers Pierre Moreau, Henri Bergson and Professor Maurice Aubert, animals are indeed unable to assimilate minerals if they have not been previously pre-digested by plants – hence our inability to assimilate almost 90% of the minerals in fresh water!

Another interesting property of marine plasma: trace elements, these catalysts of our main biological functions, are directly assimilated, without transporters such as picolinates or glycinates, due to the presence of negative ions in seawater.

Why is all this so important? Quite simply because minerals play an essential role in the proper functioning of the body: bone resistance, muscle contraction, regulation of blood pH, development of hormones and enzymes, assimilation of vitamins, etc.


Quinton water has the advantage of being suitable for a wide range of uses. The most common use is that of revitalising the body: by providing us with trace elements when we’re lacking in them, it helps to improve our metabolism and to reinforce our immune system. It is also a powerful remineraliser. This property allows it to stimulate the activity of the body’s cells.

Besides these two main properties, it has many benefits. It stimulates blood flow, thus reducing the feeling of ‘’heavy legs’’, it stimulates a feeling of wellbeing and vitality, facilitates digestion, helps fight chronic fatigue, mood disorders and even sexual issues.

It can be used as a preventive measure, for example by athletes, to prevent muscle cramps or dehydration. It can also help relieve certain pains, such as musculoskeletal disorders such as arthritis or tendonitis.

But it can also heal various illnesses:

  • Skin diseases (acne, eczema, psoriasis), used in local application;
  • ENT issues such as rhinitis, sinusitis, used as a spray for the nose;
  • Problems related to the digestive system (gastroenteritis, diarrhea), consumed by ingestion.

To find out more about the benefits of this seawater, I recommend the excellent book by Jean-Claude Rodet and Maxence Layet Quinton: Le sérum de la vie.


The world of conventional medicine shows little interest in Quinton plasma. Perhaps because the consumption of this marine serum is more “preventive” than “curative”. However, some significant figures such as Dr. Luc Bobin, specialist in natural medicine, or Dr. Marc François Paya, specialist in pain, regularly highlight the virtues of seawater, which they readily prescribe to their patients.


There are different ways to administer the plasma and different dosages, depending on the context.

Quinton water can be administered by way of ingestion, injection, or local application.


When ingested, the product takes the form of drinkable ampoules, bottles or even Bag-in-Box. The dosage is as follows:

  • baby: 5 to 10 ml of isotonic marine plasma once a day, 2 to 3 times a week (talk to your pediatrician beforehand)
  • child: 10 ml of isotonic marine plasma morning and evening during growth
  • Adult:
    • first phase of cleanse – 30ml of isotonic marine plasma per day, for about 2 weeks
    • second phase of cleanse – 150 ml to 300 ml of isotonic marine plasma per day. A one week break every 3 weeks is recommended during the treatment

Of course, this dosage can be adjusted according to individual needs: an athlete for example may need to take 5 to 6 drinkable ampoules of 30 ml per day!

In any case, naturopaths strongly recommend that you drink no more than one litre of isotonic water per day.

It is also advisable to keep the liquid under the tongue for about 1 minute before swallowing, to ensure the proper distribution of minerals and trace elements throughout the body.

If you are pregnant, have high blood pressure, have heart problems, or are on a salt-free diet, please seek medical advice before starting treatment.

Quinton Isotonic®


For injection, Quinton water should be isotonic and administration should be done in the presence of a qualified professional. It is the oldest system of administration but also the most gentle.

Patient testimonials show real relief from pain (osteoarthritis, back pain, etc.) post-session. Please note, however, that the sale of injectable Quinton is currently prohibited.

As the European pharmacopoeia deems cold microfiltration unsatisfactory with regard to sterilisation standards, the product has indeed lost its Marketing Authorisation.


Finally, topically, hypertonic or isotonic seawater can be administered as a compress. This method is particularly effective when it comes to skin problems.

It can also be found in nose sprays, eye drops, and mouthwashes.


As a general rule, closed bottles of marine plasma, in isotonic or hypertonic version, can be stored sheltered from light and at room temperature (4°C minimum and 35°C maximum) for:

  • 2 years in glass bottles
  • 3 to 4 months in plastic bottles

After opening, the hypertonic solution can be consumed for several weeks without issue, as long as the cap is tightly closed and the product is stored in a cool, dark place. On the other hand, if you have made the isotonic mixture yourself, it is recommended that you consume it within 2 to 3 days.

Pour the liquid into a glass bottle and protect it from light, in a cool place or place with little exposure to temperature variations. It does not need to be stored in the fridge.

If in doubt, you can always refer to the best-before date (BBD) indicated on the label.



Nowadays, numerous studies show it, the mineral water we drink is of bad quality. It contains traces, tiny but nonetheless visible, of pesticides, fungicides, insecticides and other drug residue. Only drinking natural mineral water sold in supermarkets amplifies the gradual intoxication a little more each day, which we are unfortunately all victims of.

Especially since the natural mineral waters we drink do not contain “bioavailable” minerals. Indeed, in order for minerals to be assimilated by the human body, they must have been “digested” beforehand by zooplankton, which feeds on plants such as phytoplankton (seaweed), which absorbs the mineral salts dissolved in water.

In other words, the minerals in bottled water are not active. It will take a lot of time and energy for the body to process and use them.

Quinton water, on the other hand, benefits from this process of transforming minerals and trace elements. By consuming it, you immediately provide the body with the elements it needs, such as sodium, magnesium and potassium. 78 elements of Mendeleïev’s table are to be found in this living substance that nature offers us!


The foods we eat today, and in particular processed products, are too fatty, too sweet, and filled with additives that are dangerous for our health… Combined with the stress that we undergo at home or at work, they contribute to modifying the acid-base balance of our body, which promotes demineralisation of the body and subsequently the emergence of illnesses such as osteoporosis, diabetes or cancer.

Eating more alkalising foods, such as fruit and vegetables – preferably raw and organic ones – is a first step in restoring this balance. But that’s not enough, because today, due to the impact of intensive agriculture, our soils have become impoverished and our food is therefore less rich in nutrients. Not to mention the harmful effects of pollution. For this reason, marine plasma is found to be an excellent natural food supplement at any age. It effectively mineralises the body to allow it to better defend itself.


Nowadays, we too easily reach for medication as soon as a small health issue pops up. Even for a cold, which is proven to go away by itself in 7 days! Of course, conventional medicine is absolutely necessary and I won’t get into the debate of being ‘’for or against’’. Nevertheless, it goes without saying that the taking of medication is often indissociable from secondary effects which can show up over a more or less long period of time and with varying degrees of intensity. And let’s not forget that the pharmaceutical industry remains a huge business that rakes in billions of euro every year.

Drinking seawater has a naturally protective effect on the human body. In addition to this preventive action, sea water also has the ability to give strength and vitality to our cells to fight all kinds of ailments, the best known of which are chronic fatigue, skin problems, digestive problems and joint disorders.

In summary, marine plasma is a natural solution, respectful of the body, and ideal for a detoxing cleanse!
