Quinton Marine Plasma is a unique food supplement that has been harvested from the ocean for more than a century. In 1897, the French biologist René Quinton discovered a method of extracting seawater from specific plankton-rich areas. This water is carefully collected at a depth of 30 metres, where it is rich in minerals and trace elements. The electrolyte ampoules contain more than 78 essential minerals and trace elements and support the balance of electrolytes in the body. More than 125 years later, this method is still used to guarantee a product of the highest quality.

More than just seawater

Quinton Marine Plasma is a natural source of minerals and trace elements, but it is very different from regular seawater. It is harvested in places where phytoplankton and zooplankton create complex biochemical processes. This results in a rich mix of nutrients that are not found in regular seawater. A careful filtration procedure preserves the natural composition. Unlike synthetic mineral supplements, Quinton Marine Plasma contains a full spectrum of natural minerals and trace elements, more than 78 in total.

The role of minerals in the body

The cells in our body are located in a fluid matrix that is essential for the exchange of nutrients and waste products. This extracellular matrix contains minerals in specific proportions that contribute to a healthy internal environment. Quinton Marine Plasma has a mineral composition that closely resembles the fluids in our body, which means it is optimally absorbed. The unique balance of these elements is not only the result of natural processes but also essential for supporting various bodily functions.

Production and purification process

Quinton Marine Plasma is obtained in a strictly controlled process. The seawater is collected from a plankton-rich zone off the French coast and then undergoes cold microfiltration to remove impurities without affecting its natural properties. This process, which has been in use for more than a century, ensures that the product retains its original composition. It is not heated and not irradiated, so the natural bioactive properties are preserved.

Osmotic balance and the name plasma

The concept of Quinton water as an oceanic blood plasma is based on the hypothesis that the first forms of life arose in a similar mineral environment. The isotonic variant has a mineral ratio that closely resembles that of human plasma. This hypertonic variant is the undiluted form and therefore more concentrated: the same origin and the same filtration process, with a higher mineral content per ampoule.

04 / What we may claim

EFSA claims for marine plasma.

Framework
EU 1924/2006
EFSA register
Subject
Marine plasma
(no amounts known)

In Europe, we may only make health claims about food supplements that have been assessed and authorised by EFSA and are listed in the official EU register. No claim outside it is permitted to us, however plausible it may sound.

For marine plasma, there is nothing in that register. Authorised claims do exist for individual minerals such as magnesium and calcium, but they only apply at a minimum of 15% of the reference intake per daily dose. The manufacturer does not state amounts per mineral, so we cannot make those claims here.

No authorised claims
Marine plasma
Regulation 1924/2006

No health claim at all has been authorised for marine plasma in the EU register.

What you read above about the origin, the harvest at a depth of 30 metres, the cold microfiltration and the composition are properties of the product and the production process. They are not health claims assessed by EFSA, nor are they intended as such. If you want to explore the literature, search for marine plasma or René Quinton in combination with the subject that interests you.

Framework: Regulation (EC) No 1924/2006 and Regulation (EU) No 432/2012. No health claim has been authorised for marine plasma and there is no claim on hold for this substance either. Claims for individual minerals require at least 15% of the reference intake per daily dose.

The content of this page has been checked for factual accuracy, from composition and dosage to compliance with the European rules on health claims. Note the difference between the two variants: hypertonic marine plasma is undiluted and therefore more concentrated than the isotonic variant, which means it contains more salt per ampoule. If you follow a low-salt diet or have high blood pressure or kidney problems, consult your doctor first. The manufacturer does not state amounts per mineral, so the exact intake per ampoule cannot be calculated.

Curator's note
One ingredient on the label: seawater, and nothing else.
Selected by Ergomax

Most mineral supplements are individual salts in a capsule, in the ratio chosen by the formulator. This is the opposite: seawater from a plankton-rich zone, cold filtered and otherwise left untouched, with the minerals in the ratio in which the ocean supplies them.

We stock it because the method is more than 125 years old and is still carried out in the same way: not heated, not irradiated, no chemical treatment. Do pay attention to which variant you choose. This is the hypertonic one, the undiluted and concentrated form.

About the brand

Laboratoires Quinton, briefly explained.

Laboratoires Quinton

The laboratory behind René Quinton's marine therapy.

Laboratoires Quinton makes products based on seawater using a process called Marine Therapy, developed by René Quinton (1866 to 1925), a French biologist and physiologist. He introduced the idea of supporting cells with pure seawater, based on the observation that the internal environment of the human body closely resembles that of natural seawater. The products are produced through a cold microfiltration process according to the Aquatic Quinton Protocol and are available as drinkable ampoules and sprays. In 2010, the René Quinton Foundation was established, which encourages research into the properties of seawater and spreads knowledge about marine therapy.

Quality and production

Cold filtered, never heated.

Quinton Marine Plasma is obtained in a strictly controlled process. The seawater is collected from a plankton-rich zone off the French coast, at a depth of 30 metres, and then undergoes cold microfiltration to remove impurities without affecting its natural properties. It is not heated and not irradiated. This process has been in use for more than a century and is called the Aquatic Quinton Protocol.

Protocol 04
Since 1897
Aquatic Quinton Protocol
The method goes back to René Quinton, who in 1897 developed a way of extracting seawater from specific plankton-rich areas. Today, Laboratoires Quinton produces according to the Aquatic Quinton Protocol, more than 125 years later.
08 / Frequently asked questions

What you still wanted to know.

Quinton Marine Plasma is seawater that is harvested at a depth of 30 metres in a plankton-rich zone off the French coast and then cold microfiltered. It contains more than 78 minerals and trace elements in their natural ratio. The hypertonic variant is the undiluted form and therefore more concentrated than the isotonic one.

Isotonic marine plasma is diluted to a mineral ratio that closely resembles that of human plasma. Hypertonic marine plasma is the undiluted form and therefore contains more minerals and more salt per ampoule. Both come from the same source and undergo the same filtration process. If you follow a low-salt diet, consult your doctor about which variant suits you.

The manufacturer recommends 1 to 3 ampoules per day, or as many as your doctor or therapist recommends. A box contains 30 ampoules of 10 ml and therefore lasts ten to thirty days. Break open the ampoule and drink the contents, diluted in a little water if you like.

The product consists of one ingredient, marine plasma, whose composition varies naturally. The manufacturer therefore states the total number of minerals and trace elements, not the individual amounts. As a result, the intake per mineral per ampoule cannot be calculated and we cannot make any EFSA claims for individual minerals either.

The seawater is collected and then cold microfiltered to remove impurities. It is not heated, not irradiated and no chemical treatment is involved, so the original composition and the bioactive properties are preserved. This process is called the Aquatic Quinton Protocol and has been applied for more than a century.

The product consists of one ingredient, marine plasma, and contains no allergens, preservatives, colourings or flavourings. As it contains no animal ingredients, it is suitable for vegetarians and vegans.

Because the hypertonic variant is undiluted, it contains more salt per ampoule than the isotonic one. If you follow a low-salt diet or have high blood pressure, heart problems or kidney problems, consult your doctor first. The same applies during pregnancy, breastfeeding and for children. This is a food supplement and not a substitute for a varied diet.
