Seawater to Drink (Marine Plasma): How to Choose and Take It Correctly

Seawater to Drink (Marine Plasma): How to Choose and Take It Correctly

Quinton water, also known assea water or marine plasma, is an exceptional water that, thanks to its composition of minerals and trace elements, is very beneficial for the human body and provides many healing properties. It has become a precious resource sought after by many people. It is named after the person who discovered it, René Quinton, who had the ingenious idea to show that Seawater and blood plasma have the same concentration of minerals and trace elements. This was later proven through studies conducted on this water, and it could therefore eliminate toxins from the body, revitalize it, and heal it.

In this article, we will explore where you can buy Quinton water, with a focus on the best type to choose. Get ready to discover the places where you can find seawater and benefit from its advantages for your well-being.

Where can one obtain Quinton water ?

Marine plasma is harvested from unpolluted ocean waters at depths of 20 to 30 meters. This seawater is then filtered (ultra-filtration) and cold-sterilized to preserve its composition of essential minerals such as calcium, magnesium, and potassium. If you wish to obtain seawater from a reliable source, there are several options available, such as: pharmacies and stores natural products who offer seawater in their dietary supplements section, specialized websites dedicated to health and well-being to buy online, or from your favorite online store Biovie who is the reference for buying high-quality marine plasma at an unbeatable price. Sourced from the Mediterranean waters of Ibiza, it is available in several formats, such as the 0.75-liter bottle of ultra-filtered marine plasma, or in large format of hypertonic plasma of 3 L, , 11 L "and" 20 L.

Which type of Quinton water should you choose? (Ampoule, bottle...)

The choice between ampoules, bottles, or nasal sprays depends on your lifestyle and how you intend to use the seawater. Here are some explanations:

Light bulbs: This form of Quinton water is very common and very convenient. The ampoules provide a precise dose of seawater and are easy to carry. You can use 1 to 3 ampoules per day, to be taken in the morning on an empty stomach and between meals.

Bottles: We have here the economical format of seawater compared to ampoules. The bottles offer a larger quantity of marine plasma, which can be convenient if you plan to undergo a few weeks of treatment with this water that has numerous benefits. The glass allows the water to be stored inertly.

Nasal spray: There are also nasal sprays containing specially formulated seawater for nasal hygiene. These sprays are used to clean and hydrate the sinuses and can be helpful in case of a cold or allergies.

Should one buy Quinton water at the pharmacy or in an organic store ?

It is possible to find seawater both in pharmacies and in organic stores. However, the choice between these two options depends on each individual's personal preferences and the quality of the products available.

The pharmacies They are specialized establishments in health products and often have a selection of dietary supplements, including marine plasma. They can be a convenient option if you are looking for reputable brands and prefer to buy your health products in a medical environment. They generally offer fairly high prices.

On the other hand, organic stores focus on natural and organic products. These stores emphasize sustainability, the quality of ingredients, and respect for the environment. If you value the organic and ethical aspects of the products you consume, organic stores are an appropriate choice.

In both cases, it is important to check the reputation of the supplier and the quality of the product. Where is the water sourced from? From the coast or by boat? How is it preserved? What analyses are conducted? These are some of the questions to keep in mind when purchasing seawater.

What is the difference between hypertonic and isotonic Quinton water ?

The difference between Hypertonic and isotonic seawater differ in their concentration of minerals, trace elements, and their therapeutic use..

Hypertonic seawater It is a highly concentrated solution of minerals compared to our blood plasma, meaning it contains a higher concentration of mineral salts, particularly sodium. This type of marine plasma undergoes no dilution or transformation; it is 100% seawater. It is used for specific applications that require a higher concentration of trace elements, such as general revitalization, recovery after intense physical exertion, in cases of demineralization, or to support the immune system. This form of marine plasma provides a rapid and immediate effect in emergency situations due to its high mineral salt content.

On the other hand, isotonic seawater It is a solution with a mineral concentration that is balanced and similar to that of our blood plasma. It undergoes dilution with fresh water, so this type of marine plasma will act deeply. It is used for more general and regular use, to maintain the body's electrolyte and mineral balance, to promote hydration, in cases of chronic problems, and to support essential biological functions. Isotonic seawater can be used daily and for all age categories, including infants and children.

In any case, it is advisable to consult a naturopath before starting to use Quinton water.

The full range Marine Plasma

What is marine plasma ? So-called hypertonic marine plasma is simply seawater harvested and filtered under very specific conditions. Our supplier Ibiza Agua de Mar collects sea water from a depth of 25 meters off the coast of Ibiza in a UNESCO listed area. Concerning the harvest, here are the different physico-chemical parameters measured during the search for an optimal place for the harvest of hypertonic marine plasma, first on the radar with reading of the currents and according to the marine weather (wind, swell, rain. ..) and then by local measurement of these different parameters: taste of seawater, dissolved O2 level, PH level, redox level (ORP), salinity level (TDS), conductivity level ( PSU), alkalimetric title (TA), Pressure. It is the empirical practice of the harvesters and the reading of the various measuring instruments that makes it possible to decide on the best complex combination of these measures together to decide whether the harvest is triggered on the site or whether another location is sought. Where does marine plasma come from ? The marine plasma is collected in the high seas, off the coast of Ibiza, in a specific area classified as UNESCO with high planktonic activity and with a presence of tens of square kilometers of Posidonia. It is indeed in this specific area that lives the largest living organism listed on Earth, a posidonia herbarium of 80,000 to 200,000 years extending over 15 kilometers in length.

Serrão: Implications of Extreme Life Span in Clonal Organisms: Millenary Clones in Meadows of the Threatened Seagrass Posidonia oceanica When is it best to take marine plasma ? The ideal is to consume marine plasma, which contains, let's remember, all the elements that make up Mendeleev's periodic table, in the morning when you get up, on an empty stomach. take 1/4 of hypertonic marine plasma to mix 3/4 of spring water or filtered water. What are the benefits of marine plasma ? Minerals are the "fuel" used primarily by our body, which is necessary for our cells to perform their functions optimally. They are also essential for the absorption of vitamins and are responsible for enzymatic processes in cells. Cells perform all their functions with maximum vitality and the precise capacity for organic, bioavailable, alkaline cellular nutrition. Thus, sea water becomes the best mineral drink since it contains all the elements of Mendeleev's periodic table. Another of the great benefits of seawater is its pH. As Otto Warbürg, father of cellular respiration and two-time Nobel laureate, said, “all diseases are acidic and where there is oxygen and alkalinity there can be no disease”. Due to the quality of our raw material, the hyper-oxygenated waters of Posidonia meadows (recognized by UNESCO as a World Heritage Site in 1999) and sea currents providing purity and clarity: Ibiza and Formentera Agua de Mar have an alkaline pH , between 8.1 and 8.4, which will help the body maintain a neutral pH through homeostasis. The ingestion of sea water is advised to control and maintain our PH, as well as an exceptional supplement for alkaline diets. The antioxidant and anti-acidity power produced by seawater is due to the alkalinity provided by the minerals. Drinking filtered seawater in a direct and controlled way is very beneficial for your health, because seawater is an excellent nutrient, containing most of the minerals of the periodic table and all of them dissolved in the best universal solvent available: l 'water. Seawater contains all the minerals of the periodic table of elements in a bioavailable way. It is thanks to this that foods cooked in seawater are rehydrated and remineralized to make foods with high nutritional power. The problem today is that our intake of minerals through food has dropped dramatically and what is causing this? The answer is very simple: pollution, soil depletion due to intensive agricultural production and our stressful pace of life have considerably reduced the quality of food and its mineral intake, drastically reducing the minimum contribution necessary for the proper functioning of the body. Seawater also helps us stay young, for a simple reason: the body regularly and cyclically regenerates all its cells, because their lifespan is limited in time. As we age, one of the first faculties the cell loses is the ability to hydrate. We know that the older we get, the less we drink, so drinking and ingesting seawater can help us "wake up" this ability to hydrate ourselves., 4 products
