General product inquiries

How do you store your seawater?

How long can I keep a bottle?

Glass bottles and closed BIBs can be kept for up to 2 years in a cool, dark place.

The best-before date is always indicated on the label.

Do I have to keep them in the fridge once opened?

No, it's not necessary, unless you don't use your Õdevie within 4-5 months.

How long can hypertonic marine plasma be kept?

Once opened, hypertonic solutions can easily be stored for several months, with no fear of evaporation. Just close the cap tightly after use.

How long can I keep my isotonic mix?

Once ready, we recommend storing it in a glass bottle.

It can be kept for 2-3 days at room temperature, but it's best to consume it as you go, always freshly prepared.

Hypertonic or isotonic?

Hyper or Iso, what's the difference?

HYPERTONIC solution is composed of 100% seawater

so it contains a lot of minerals.

When you drink it, your body has to compensate for this excess and rebalance its water content. It is therefore recommended to drink it in small quantities for its tonic effect and over a period of 5 to 7 days.

However, it should be avoided by people with high blood pressure or water retention problems.

ISOTONIC solution is a solution prepared by diluting Õdevie hypertonic

with spring water or water with low mineral content, to obtain a drink with the same iono-mineral composition as blood plasma or extra-cellular fluid, and therefore 100% assimilable.

Benefits: its properties make it a directly assimilable, remineralizing, revitalizing and draining drink.

What is low mineralized spring water?

Water with dry residue levels of no more than 130 mg per liter (see bottle label).

For mains water, ask your town council, etc. for details.

What are nasal sprays used for?

Isotonic for prevention

Nasal spray can be used daily to maintain your nasal mucous membranes and support their proper function. Mucous membranes are the first barrier against viruses and bacteria!

Directions for use :

1 spray of isotonic solution in each nostril, morning and evening.

Hypertonic against colds and coronavirus:

The ELVIS study by the University of Edinburgh showed that nasal irrigation and gargling with hypertonic solution reduced the duration of upper respiratory infections by several days.


Nosewashing and gargling with hypertonic solution up to 12 times a day.

In fact, participants in the ELVIS study reduced the duration of their infection (cold or coronavirus) by 1.9 days, over-the-counter medication consumption by 36%, contagion by 35%, and their viral range.

Find our sprays directly in the store, by the unit or in the assortments (more advantageous)!

What's that little device under the bottle?

A little white thing under the bottle?

It's a torsion field corrector. From the place of capture to the delivery of the product to you, we place torsion field correction devices all along the way to protect the product.

You'll find the device under each of your bottles (except 250ml packs) and on the bags of BIBs, near the tap, which we recommend you to leave in place to preserve this correction.

> Before taking your empty bottles to the garbage dump, you can pick up this device and use it to install it on your phone, tablet, etc. or any other product/device subject to or emitting waves.

Can anyone consume?

Isotonic solution

There are no restrictions, but ALWAYS test with small quantities and gradually increase.

Find out more on the Consume page, according to your profile or goal.

See the video on how to prepare isotonic solution.

Hypertonic solution

NOT INDICATED for people with high blood pressure or kidney problems.

For all others: 10 to 20 ml (up to max. 50 ml) a day for 1 to 7 days.

Hold the dose in the mouth for a moment, salivate well and then swallow.

A boost in case of extreme fatigue or long-term effort (sports).


In case of severe or long-standing illness, ALWAYS start with small quantities of hypotonic.

HYPOTONIC = more diluted, i.e. 1 volume of hypertonic for 4 to 5 volumes of spring or low-mineralized water.

Start with 1 to 3 tablespoons of this mixture for 1 week.

If you observe NO adverse effects, then you can drink up to 50 ml per day of hypotonic solution.

CAUTION: increase very slowly to 50 ml, or 100 ml if you feel better.

ALWAYS seek your doctor's advice.

An important source of magnesium, yes, but how much?

Magnesium, yes, but how much?

Our hypertonic solution contains 1290mg of magnesium per liter.

What type of magnesium?

Only naturally-occurring magnesium from the sea. NO added magnesium.

Why is Õdevie an important source of magnesium and other bioavailable minerals?

It comes from the zone we pump the seawater:

  • geologically characterized by tectonic tensions

    (linked to the meeting of the African and European plates)
  • known for its ongoing underwater volcanic activity; this releases and displaces large quantities of mineral substances
  • the Alboran Sea, swept by powerful marine currents (surface and deep),

    linked to the Mediterranean-Atlantic junction.

    These currents, known as "upwelling", resuspend minerals and promote their dissolution and incorporation into the morphological structure of the water.
  • and also: 2 gigantic circular movements (gyres) that dynamize the water.

All these factors induce intense planktonic activity that "pre-digests" minerals and makes them bio-available.

The result is super-dynamized water that is particularly rich in bio-available minerals (12-15% more minerals than ocean water). Quality details

Who is René Quinton?

René Quinton is a famous biologist who demonstrated the similarity between blood plasma and isotonic marine plasma. This similarity explains the remarkable effectiveness of seawater cures.
