Marine plasma: benefits and uses
Written on January 28, 2026, by Pauline de Santarome
Marine plasma is attracting growing interest in natural health. Often referred to as "water of life," this liquid is rich in minerals and bioavailable trace elements and has a composition remarkably similar to human blood plasma. Used to revitalize the body, it addresses modern deficiencies, fatigue, and physiological imbalances. Whether for immunity or energy, this dietary supplement offers a comprehensive approach to well-being.

What is marine plasma?
Marine plasma is filtered seawater drawn from specific areas of the ocean known for their purity. Unlike coastal water, this liquid is harvested from the open sea, where plankton activity transforms inorganic minerals into organic elements that can be absorbed by your body.
Definition, origin, and distinction of types
The origin of marine plasma determines its quality. It is drawn from the heart of plankton vortexes, particularly in the Alboran Sea and the Bay of Biscay, at a depth of 10 to 30 meters where the concentration of mineral nutrients is optimal. This zone allows for the pre-digestion of minerals by plankton, making them highly bioavailable.
Harvesting follows the protocol developed by biologist René Quinton. The water undergoes cold microfiltration (0.22 microns) in the laboratory, removing impurities and bacteria without heating or irradiation, thus preserving vitamins and trace elements.
It is essential to distinguish between:
Raw seawater: Contains pollutants, unfit for consumption.
Marine serum (or Quinton plasma): Finished product, filtered and safe.
Marine plasma: Complete mineral matrix (totum) containing all 78 elements of the periodic table (magnesium, zinc, iodine, etc.).
"Marine plasma contains up to 78 minerals and trace elements (magnesium, calcium, potassium, zinc, selenium, iodine, etc.), whose bioavailability is optimized by phytoplankton." (Begoña Basterrechea - René Quinton Foundation)
Isotonic vs. hypertonic marine plasma: composition and mineral concentration
Marine plasma exists in two main forms: hypertonic and isotonic. Their mineral salt concentrations differ, dictating their uses.
Find our products here: Isotonic Marine Plasma or Hypertonic Marine Plasma, which follow René Quinton's protocol.

The main health benefits of marine plasma
Strengthening the immune system
Marine plasma effectively supports your natural defenses. Its high content of trace elements such as zinc, copper, and selenium contributes to the normal functioning of the immune system. These micronutrients act as enzymatic cofactors, facilitating the activation of immune cells. A course of treatment at the change of seasons strengthens your biological terrain against external aggressions.
Support for vitality
When you're feeling sluggish, marine plasma (especially hypertonic) acts as a powerful revitalizer. Its magnesium and phosphorus content reduces fatigue and supports energy metabolism. Unlike stimulants such as caffeine, marine minerals recharge your cellular batteries for the long term, providing a boost of energy without causing addiction to combat physical and mental exhaustion.
Mineral balance and detoxification
Marine plasma restores homeostasis, your body's internal balance. By providing all the necessary minerals, it promotes cellular exchange and waste elimination. A well-mineralized extracellular environment allows your cells to nourish themselves better and reject toxins. Isotonic plasma is ideal for draining your body and restoring acid-base balance. The chloride present in marine plasma has a specific effect on the production of stomach hydrochloric acid.
Benefits for athletes and physical performance
For athletes, maintaining electrolyte balance is crucial. Marine plasma is an ideal 100% natural sports drink.
Accelerates and supports recovery after exercise: Your body in metabolic acidosis loses minerals through perspiration. The intake of mineral ions buffers acidity (lactic acid) and restores reserves, reducing fatigue and recovery time.
Improved hydration and endurance: Magnesium and potassium retain water in your tissues and optimize blood volume. Optimal hydration promotes endurance and maintains your cognitive abilities (concentration).
Prevention of muscle cramps: Cramps often indicate a magnesium or potassium deficiency. Marine plasma provides a constant supply of minerals essential for muscle contraction, limiting the risk of spasms.
Marine plasma and beauty: an ally for skin, hair, and nails
Beauty reflects your mineral status. Marine plasma deeply nourishes tissues thanks to sulfur, zinc, and silicon, which are essential for collagen and elastin. Isotonic plasma rehydrates dry skin and soothes atopic skin. For your hair and nails, marine nutrients strengthen keratin.
How can you incorporate marine plasma into your daily routine?
Integration must be gradual and tailored.
Choice of shape: Glass bulbs are the safest format for storage.
Hypertonic: For an energy boost, intense fatigue, or before exercise.
Isotonic: For deep cleansing, cellular rehydration, or sensitive skin types.
Precautions and contraindications: Marine plasma contains sodium.
Hypertonic plasma is not recommended in cases of high blood pressure, kidney or heart problems, or salt-free diets. The isotonic form is often tolerated, but medical advice is still recommended.
Pregnant or breastfeeding women: medical advice is recommended.
Tips for maximizing the benefits:
Time of intake: In the morning on an empty stomach, 15-20 minutes before breakfast. Keep the liquid under your tongue (sublingual) for one minute for optimal absorption.
Lifestyle: Combine the treatment with a plant-based diet to maintain acid-base balance.
Hydration: Drink enough water to facilitate the elimination of toxins initiated by remineralization.
Marine plasma is a natural resource that reconnects your internal environment with essential elements. It has profound benefits for boosting immunity, supporting athletic performance, and restoring vital balance. By choosing a high-quality product that complies with René Quinton's protocol, you allow your body to regenerate naturally.
Marine plasma can be used as a supplement in a wellness program. In cases of persistent fatigue, specific disorders, or medical conditions, it is recommended that you seek advice from a healthcare professional (doctor or pharmacist) before use.
What are the benefits of marine plasma?
Marine plasma revitalizes thanks to its 78 minerals and trace elements. It combats fatigue, strengthens the immune system, improves rehydration and cellular function, and supports athletic recovery. It also contributes to acid-base balance and skin beauty. Used as an eye spray, it helps relieve discomfort associated with dry eye syndrome.
