Understanding and using Quinton plasma with confidence

Quinton plasma is seawater collected from phytoplankton vortexes, then processed using the AQP protocol: 0.22 µm cold microfiltration, strict microbiological testing, and, for the isotonic version, dilution in very low-mineralized spring water. This process preserves up to 78 bioavailable trace elements and guarantees the absence of pathogens.

Hypertonic / isotonic: what do these terms mean?

Here is the difference between the two versions: 

• Hypertonic solution: approx. 33 g NaCl · L⁻¹, or an osmolarity of around 2,400 mOsm; it contains three times more salts than our internal fluids and is suitable for occasional needs for rapid remineralization.

• Isotonic solution: approx. 9 g NaCl · L⁻¹, thus close to human extracellular serum (≈ 300 mOsm). It is designed for gentle, daily rebalancing, particularly for sensitive individuals. 

Plasma, serum, seawater: what are the differences?

In physiology, blood plasma refers to the liquid fraction of blood that still contains clotting factors, whereas serum lacks them. Seawater, on the other hand, contains more sodium, chloride, and magnesium ions than human plasma; it must therefore be adjusted (isotonic) before regular consumption. Defining these terms avoids any confusion.

Documented mineral deficiency

When a diet low in fruits, vegetables, or whole grains leads to an insufficient intake of magnesium, zinc, or iodine, short-term use of a hypertonic solution can help restore these reserves more quickly.

Functional fatigue or periods of intense exertion

Randomized controlled trials conducted in postmenopausal women show that the combination of physical activity and marine microfiltration improves isokinetic strength and reduces certain types of pain.

Support for athletic recovery

For athletes, this hydro-mineral replenishment accelerates glycogen recovery and reduces cramps thanks to the synergistic intake of sodium, potassium, and magnesium.

Hydration in Hot Climates

Its high electrolyte content promotes better water retention compared to plain water, which is beneficial during stays in arid climates or episodes of gastroenteritis, heatstroke.

Here are the main benefits of this natural solution: 

• Cellular rehydration: the sodium-chloride pair promotes water absorption through co-transport, contributing to effective osmosis in the intestines.

• Support for acid-base balance: the presence of bicarbonates and citrates buffers fluctuations in systemic pH.

• Combined supply of trace elements: manganese, selenium, and zinc play a role in antioxidant enzyme systems (SOD, GPx).

• Immune modulation: An in vitro study suggests an impact on certain cytokine biomarkers, with no pro-inflammatory effect observed.

• Support for bone density: in elderly subjects, marine supplementation combined with elastic resistance modestly but significantly increases femoral bone mineral density.

• Support for nutritional balance and hair vitality: The minerals and trace elements naturally present in marine plasma contribute to the body’s overall nutritional balance. As part of a varied diet and proper hydration, these nutrients contribute to the intake necessary for the proper functioning of tissues, particularly the scalp and hair follicles. An adequate intake of micronutrients is indeed considered an important factor in supporting the hair growth cycle and preserving hair vitality over time.

To fully benefit from Quinton plasma’s remineralizing potential, always combine its use with regular hydration and a varied plant-based diet. Clinical observations show rapid subjective benefits—increased vitality, better recovery—in athletes athletes or those subjected to heat stress, while the isotonic solution serves more as a foundation to support fragile systems. The key remains personalization: duration, concentration, and frequency are tailored to each metabolic profile.
