More information

Propos'Nature's ISOTONIC and HYPERTONIC MARINE PLASMA are meticulously crafted following René Quinton's established protocol.

Source and Quality
Location: The seawater is sourced from the coast of the English Channel in France, known for its high tides that naturally invigorate the water.

Purity: Pumping sites are selected for their cleanliness, situated far from river currents and ports, ensuring they are free from hydrocarbon pollution.

Depth: The water is drawn from optimal depths rich in phytoplankton, which aids in the natural fixation of various sea salts.

Filtration: The only treatment applied is double sterile filtration at 0.2 microns in the cold, ensuring purity without compromising the water's natural properties.

Packaging: The seawater is packaged without any additives or preservatives.
