Our 500 ml drinkable isotonic seawater, also called isotonic marine plasma, is a drinkable solution of marine origin, naturally mineralized and ready to use.
It is obtained from hypertonic seawater 34‰, diluted with osmotically purified water to obtain a concentration close to isotonicity, around 9‰.
The seawater used is pumped in France, in the Bay of Saint-Malo, Brittany, then cold microfiltered to 0.20 µm according to the original René Quinton protocol.
A ready-to-use isotonic solution
Unlike hypertonic seawater, isotonic seawater is already diluted. It can therefore be consumed directly according to the instructions for use indicated on the packaging, without further dilution.
Its 9‰ concentration corresponds to a milder solution, less concentrated in mineral salts than hypertonic seawater at 34‰.
Origin France – Brittany
The seawater comes from the Brittany coast, in the Bay of Saint-Malo area, a marine environment renowned for its natural richness.
This French origin allows us to offer a quality marine plasma, made from carefully selected seawater.
René Quinton's original protocol
This isotonic marine plasma is prepared according to René Quinton's original protocol, historically associated with filtered and diluted seawater preparations.
This approach aims to preserve the natural richness of seawater while obtaining an isotonic solution suitable for drinkable consumption.
Cold microfiltration 0.20 µm
The product is cold microfiltered to 0.20 µm, without heating, in order to best preserve the natural mineral composition of the seawater.
This fine filtration provides a clear, controlled, and ready-to-use solution.
No additives or preservatives
The composition is simple: hypertonic seawater 34‰ and osmotically purified water.
No additives, no preservatives, and no flavors are added.
Naturally mineralized
Isotonic seawater naturally contains marine minerals and trace elements from the seawater itself.
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.
