Quinton water (marine plasma): origin, composition, uses and precautions
Your body is made of seawater. Not metaphorically - literally. This is what biologist René Quinton understood more than a century ago, and what modern physiology confirms today: the mineral composition of human blood plasma is almost identical to that of diluted seawater. 78 minerals and trace elements, all present in ionic and bioavailable form - that's what Quinton® plasma contains.
Since I have been leading Biovie in 2007, I have seen hundreds of clients take an interest in marine plasma. This comprehensive guide answers all your questions: what it really is, how to take Quinton® plasma - and most importantly, how to choose the right form for your situation.
What exactly is Quinton® plasma ?
A cold-filtered seawater, not an ordinary mineral water
Quinton® is a registered trademark, also we are not allowed to use this term in our product sheets. Nevertheless, we can talk about René Quinton and his discoveries. We often hear about seawater as if it were a common product. This is not at all the case with the Quinton® plasma, and the confusion often comes from there.
The essential difference is the harvesting and filtration protocol. A collection in the high seas, at more than 30 meters deep in areas with active plankton. Then a cold microfiltration - to 0.22 microns for culinary formats, to 0.01 microns for the purest formats for direct consumption. No heat. No pasteurization.
It is also important to know that there are two distinct regulatory forms:
Marine plasma ultrafiltered - harvested at 25 meters, filtered at 0.01 µm - packaged in glass bottles, intended for direct consumption
Marine plasma microfiltered - harvest at 3-4 meters, filtration at 0.22 µm - intended for culinary use
This point on regulation is important: only the first strictly adheres to the protocol inherited from the work of René Quinton, particularly regarding the level of filtration. This is not marketing - it is a distinction that European regulation itself establishes.

The story of René Quinton: the biologist who changed our view of the ocean
René Quinton was not an amateur naturopath. He was a rigorous biologist, whose work was published by Masson in Paris in 1904 in a foundational book: Seawater, organic environment. Its central thesis? The marine origin of cellular life means that our cells are immersed in an environment whose ionic composition is very similar to seawater - albeit diluted. It's a biological continuity, not a metaphor.
To validate this thesis, René Quinton conducted a spectacular experiment that is still cited today: he replaced a dog's blood plasma with diluted seawater. The animal not only survived but also recovered. These experiments from 1904 laid the foundations for a practice that continues to evolve more than a century later.
The composition of Quinton® plasma: 78 minerals
Key minerals
Quinton® plasma is a registered trademark. Here are the main minerals found in it.
Seawater contains in particular magnesium, calcium, potassium, iodine and zinc, as well as trace elements (manganese, selenium, copper, boron, silicon) present in tiny amounts.
In seawater, 78 elements from Mendeleev's periodic table can actually be found - such as gold and silver - at very low concentrations.
These minerals are present in ionic form, that is, dissolved in water.
To give you some numerical benchmarks:
The Concentration of salts in natural seawater (hypertonic plasma): 33 to 35 g/L
The isotonic form reduced to 9 g/L - that is the same concentration as your blood plasma
A classic mineral water: 5 to 8 major minerals - Quinton® plasma offers 78+
Quinton Plasma® vs regular mineral water: the main differences
Mineral diversity : mineral water, 5 to 8 minerals - Quinton® plasma, 78+ minerals and trace elements
Chemical formula : mineral water, dissolved salts - Quinton® plasma, ionic form
Spectrum of trace elements : mineral water, variable traces - Quinton® plasma, 78 elements of the Mendeleev table
Origin and protocol : mineral water, terrestrial source capture - Quinton® plasma, high sea, active plankton, cold microfiltration
Isotonic or hypertonic plasma: which one is right for you ?
This is the number one question our clients ask me about the Quinton® plasma isotonic or hypertonic, which one to choose, and the response deserves to be clarified without jargon.
The Quinton® isotonic plasma (9 g/L) is diluted to the same concentration as your blood plasma. It is gentle, suitable for daily intake over the long term, with no duration restrictions.
The Quinton® hypertonic plasma (33-35 g/L) is seawater at its natural concentration, without dilution. More concentrated, it is used in a short 3-week course.
To help you decide between Quinton® plasma isotonic or hypertonic :
Choose the isotonic if you want daily intake or if you are a beginner
Choose the hypertonic if you want a short course
Simple rule : if you are still hesitating, start with the isotonic one
How to take Quinton® plasma? Dosage and practical protocols
Daily dosage for a healthy adult
The Dosage of Quinton® plasma for adults the most common is on an empty stomach in the morning, via sublingual absorption: you keep the liquid in your mouth 30 seconds before swallowing.
Quinton® isotonic water : 25 mL diluted in a glass of water
Quinton® hypertonic water : 25 mL per day, pure or slightly diluted
Intensive Cure Protocol 3 Weeks (Hypertonic)
The classic protocol, used for decades:
3 weeks of treatment at a rate of 25 mL of Quinton® hypertonic plasma per day, in the morning on an empty stomach
A one-week break between each treatment - this break is not optional
Resumption as needed
Are there any contraindications to be aware of ?
The Contraindications of Quinton® plasma to know, in full transparency:
Severe hypertension or severe renal insufficiency - the form hypertonic is not recommended
Medically prescribed strict salt-free diet
Children under 3 years old: hypertonic form not recommended
Pregnant or breastfeeding women: medical advice recommended as a precaution
The side effects of Quinton® plasma are rare with the isotonic form, generally well tolerated by everyone. If in doubt, talk to your doctor.
Hypertonic seawater in cooking: the salt shaker of the future ?
This is the angle I particularly like to develop because it completely changes the perception we have of seawater. We think of it as a "health supplement in a vial," and we overlook a daily use: replace salt in your cooking.
Why replace table salt with seawater ?
Refined table salt contains exactly two minerals: sodium and chlorine. The industrial refining process removes almost all trace elements. Seawater, on the other hand, contains 78 minerals in ionic form. To visualize the difference:
Refined salt : 2 minerals (Na + Cl)
Unrefined sea salt : 10 to 20 minerals
Biovie sea water (spray or bag-in-box): 78+ minerals
The Biovie spray: how to use it daily to replace table salt
The hypertonic sea water spray Biovie is the simplest way to use seawater in your diet. Here are the uses I regularly practice as a substitute for table salt:
Final seasoning on all cold preparations - salads, raw vegetables, carpaccios
Marinades and sauces
Vegetable juice and green smoothies - just a few presses are enough
Raw soups and gazpachos
Steam cooking - add at the end of cooking
The Biovie bag-in-box: the economical option for families and cooks
Our clients who use thesea water in a canister both in the kitchen and in mineral therapy have adopted our 15L or 20L bag-in-box. Frankly, it's hard to blame them.
The concrete advantages of this format:
Cost per liter significantly lower than bulbs or small bottles
Zero single-use plastic - coherent ecological approach
Integrated faucet for direct use without handling
Perfectly suited for daily cooking and family mineral treatment.
For cooking with hypertonic seawater : a practical ratio - one part seawater to four parts freshwater is enough to naturally salt your pasta, rice, or steamed vegetables.
What is marine plasma ?
So-called hypertonic marine plasma is simply seawater harvested and filtered under very specific conditions.
Our supplier Ibiza Agua de Mar collects sea water from a depth of 25 meters off the coast of Ibiza in a UNESCO listed area.
Concerning the harvest, here are the different physico-chemical parameters measured during the search for an optimal place for the harvest of hypertonic marine plasma, first on the radar with reading of the currents and according to the marine weather (wind, swell, rain. ..) and then by local measurement of these different parameters: taste of seawater, dissolved O2 level, PH level, redox level (ORP), salinity level (TDS), conductivity level ( PSU), alkalimetric title (TA), Pressure. It is the empirical practice of the harvesters and the reading of the various measuring instruments that makes it possible to decide on the best complex combination of these measures together to decide whether the harvest is triggered on the site or whether another location is sought.
Where does marine plasma come from ?
The marine plasma is collected in the high seas, off the coast of Ibiza, in a specific area classified as UNESCO with high planktonic activity and with a presence of tens of square kilometers of Posidonia. It is indeed in this specific area that lives the largest living organism listed on Earth, a posidonia herbarium of 80,000 to 200,000 years extending over 15 kilometers in length.

When is it best to take marine plasma ?
The ideal is to consume marine plasma, which contains, let's remember, all the elements that make up Mendeleev's periodic table, in the morning when you get up, on an empty stomach. take 1/4 of hypertonic marine plasma to mix 3/4 of spring water or filtered water.
What are the benefits of marine plasma ?
Minerals are the "fuel" used primarily by our body, which is necessary for our cells to perform their functions optimally. They are also essential for the absorption of vitamins and are responsible for enzymatic processes in cells. Cells perform all their functions with maximum vitality and the precise capacity for organic, bioavailable, alkaline cellular nutrition. Thus, sea water becomes the best mineral drink since it contains all the elements of Mendeleev's periodic table.
Another of the great benefits of seawater is its pH. As Otto Warbürg, father of cellular respiration and two-time Nobel laureate, said, “all diseases are acidic and where there is oxygen and alkalinity there can be no disease”. Due to the quality of our raw material, the hyper-oxygenated waters of Posidonia meadows (recognized by UNESCO as a World Heritage Site in 1999) and sea currents providing purity and clarity: Ibiza and Formentera Agua de Mar have an alkaline pH , between 8.1 and 8.4, which will help the body maintain a neutral pH through homeostasis. The ingestion of sea water is advised to control and maintain our PH, as well as an exceptional supplement for alkaline diets.
The antioxidant and anti-acidity power produced by seawater is due to the alkalinity provided by the minerals.
Drinking filtered seawater in a direct and controlled way is very beneficial for your health, because seawater is an excellent nutrient, containing most of the minerals of the periodic table and all of them dissolved in the best universal solvent available: l 'water.
Seawater contains all the minerals of the periodic table of elements in a bioavailable way. It is thanks to this that foods cooked in seawater are rehydrated and remineralized to make foods with high nutritional power. The problem today is that our intake of minerals through food has dropped dramatically and what is causing this? The answer is very simple: pollution, soil depletion due to intensive agricultural production and our stressful pace of life have considerably reduced the quality of food and its mineral intake, drastically reducing the minimum contribution necessary for the proper functioning of the body.
Seawater also helps us stay young, for a simple reason: the body regularly and cyclically regenerates all its cells, because their lifespan is limited in time. As we age, one of the first faculties the cell loses is the ability to hydrate. We know that the older we get, the less we drink, so drinking and ingesting seawater can help us "wake up" this ability to hydrate ourselves., 4

Quinton® plasma is a cold-filtered seawater that contains the minerals of seawater at low concentration. I cannot promise you any effect on your health: rather, I explain how to use it and what precautions to take.
What is the difference between isotonic and hypertonic Quinton® plasma ?
The isotonic solution (9 g/L) is diluted to the same concentration as your blood plasma: suitable for daily intake. The hypertonic solution (33-35 g/L) is seawater at its natural concentration: it is used in a short 3-week course. In case of doubt, always start with the isotonic solution.
What are the contraindications of Quinton® plasma ?
The hypertonic form is not recommended in cases of severe hypertension, severe renal insufficiency, or a strict salt-free diet. Children under 3 years old should not consume the hypertonic form. Pregnant or breastfeeding women: medical advice is recommended as a precaution. In all cases, start with a half-dose for the first few days to assess individual tolerance.
How to take Quinton® plasma?
On an empty stomach in the morning, hold the liquid in the mouth for 30 seconds before swallowing (sublingual absorption). Isotonic: 25 mL diluted in a glass of water. Hypertonic: 25 mL, pure or slightly diluted. The most common practice is a 3-week course followed by a one-week break.
Can Quinton® plasma be taken every day ?
Yes, the isotonic form is suitable for daily use over the long term. The hypertonic form is used in courses of up to 3 weeks followed by a break.
What should I do in case of a diagnosed condition?
Ask your doctor for advice before taking it in case of a diagnosed condition.
Where to buy authentic and quality Quinton® plasma ?
Prioritize traceable sources: harvesting in the high seas at more than 20 meters, areas with high active plankton, cold microfiltration without pasteurization. Biovie offers marine plasma selected according to these strict criteria, with complete transparency on the origin and protocol.
How to use hypertonic seawater in cooking to replace salt ?
Hypertonic seawater can completely replace refined salt in your preparations. The Biovie spray is used directly on dishes as a final seasoning. For cooking, incorporate seawater at the end of cooking. For pasta or vegetables, a ratio of one part seawater to four parts fresh water is enough to naturally salt.
The Biovie seawater bag-in-box: is it economical and practical ?
The Biovie bag-in-box (available in 15L and 20L) is the most economical solution for regular users in a culinary format. The integrated tap allows for direct use without handling. It is also the most environmentally friendly format: zero single-use plastic. Ideal for families who use seawater both in cooking and as a daily mineral cure.
Here - this guide does not claim to have said everything about Quinton® plasma. The science surrounding seawater is much broader, and René Quinton's work continues to inspire exciting contemporary research. What I wanted to provide here are honest practical guidelines - so that you can make informed choices, without jargon and without excessive promises.
