Our 500 ml drinkable hypertonic seawater, also known as hypertonic marine plasma, is undiluted natural seawater, naturally concentrated at 34‰.
It is made from seawater collected in France, on the Brittany coast, then cold microfiltered to preserve its natural mineral richness.
Developed according to the original René Quinton protocol, this seawater retains its natural composition of marine minerals and trace elements.
100% natural hypertonic seawater
This hypertonic seawater is undiluted and contains only one ingredient: seawater.
It is formulated without additives, preservatives, flavourings, or heat treatment.
Its natural concentration of 34‰ corresponds to hypertonic seawater, which is more concentrated than an isotonic solution.
Origin France – Brittany
The seawater is collected in France, on the Brittany coast, particularly in the Bay of Saint-Malo area according to supplier information.
This French marine origin allows us to offer quality marine plasma, from an environment known for its natural richness.
Cold microfiltration 0.20 µm
The product is cold microfiltered at 0.20 µm, without heating, to best preserve the natural mineral composition of the seawater.
Analyzed & certified seawater: each batch undergoes physico-chemical and microbiological analyses to guarantee compliance, safety, and consistent composition.
Naturally rich in minerals and trace elements
Hypertonic seawater is naturally rich in marine minerals and trace elements.
Supplier datasheets particularly mention the natural presence of chloride, magnesium, and iodine.
This marine plasma is a concentrated marine solution, appreciated by consumers looking for a mineral intake of marine origin.
Practical 500 ml format
The 500 ml format is practical for regular use and easy to dose.
It is suitable both for discovering the product and for daily use according to the advice indicated on the packaging.
Naturally mineralized
Isotonic seawater naturally contains marine minerals and trace elements from seawater.
Its concentration being lower than that of hypertonic seawater, it constitutes a milder marine solution, suitable for use according to the recommendations indicated on the packaging.
Important information
This drinkable solution is not a medicine. It is not a substitute for a varied, balanced diet and a healthy lifestyle.
Do not exceed the recommended daily dose. Keep out of reach of young children.
