Seawater from Brittany: Where Our Nasal Sprays Begin

A seawater nasal spray is only as good as its seawater. Neomedis sources the seawater for all its nasal sprays in one place: Cancale Sud, in Brittany (France), an exceptional site on the Channel coast.

Cancale: one of the purest areas of France

Cancale is world-renowned for its oysters and its intense ocean tides. The bay is an ecological sanctuary where the sea is constantly renewed. The local oysters act as natural biological pre-filters: they purify the seawater while preserving its delicate balance and its richness in mineral trace elements.

The sourcing area is rated A, the highest quality level, by IFREMER, the French research institute for the exploitation of the sea.

Strict limits on every possible contaminant

In partnership with IFREMER, Neomedis has set strict threshold values for all possible environmental contaminants. These limits guarantee a safe and consistent seawater, batch after batch.

Cold micro-filtration that preserves the minerals

Traditional methods purify seawater with heat or radiation, which degrades its active trace minerals. Neomedis uses a gentler process: a cold triple micro-filtration at 0.1 µm. It eliminates pathogens while keeping a natural solution with all its minerals and trace elements. The result is 100% natural and preservative-free.

Why minerals make the difference

Unlike a simple saline solution (water and sodium chloride), natural seawater keeps active ions such as magnesium, calcium and manganese. They help soothe tissue inflammation, nourish the nasal cilia so that they sweep away trapped mucus more effectively, and support the repair of membranes damaged by pollution or inflammation.

From Brittany to every formula

This seawater is the base of the whole Neomedis range, manufactured in France at GMP sites:

• the isotonic HYPOMER® SOFT and BABY for daily nasal hygiene;
• the hypertonic HYPOMER® STRONG, FRESH and RELAX to decongest the nose;
• the patented ZYLOMER® seawater and xylitol formulas.

Each one is packed in a preservative-free bag-on-valve spray. Explore the full product range.
