Quinton Hypertonic Ampoules are made from 100% seawater, carefully cold micro-filtered to preserve its naturally occurring mineral composition. This concentrated solution delivers electrolytes and trace elements in their natural ionic form, including magnesium and chloride.

Each daily intake provides magnesium, which contributes to electrolyte balance, the reduction of tiredness and fatigue, normal muscle function, and the normal functioning of the nervous system. The formulation also contains chloride, which contributes to normal digestion by supporting the production of hydrochloric acid in the stomach.

The seawater is responsibly sourced and preserved without preservatives, additives, sweeteners, sugars, binders, or fillers. Quinton Hypertonic fits easily into a busy daily routine and can be used before or after physical activity as part of a balanced diet and healthy lifestyle.

Quinton uses pure, cold-microfiltered seawater that contains 78 naturally occurring minerals and trace elements in their original ionic form, closely reflecting the mineral balance of human extracellular fluid. Sourced from protected ocean zones, it preserves the ocean’s full electrolyte profile through gentle cold microfiltration, avoiding additives or alteration. Unlike single-mineral supplements, this approach maintains the natural synergy and balance found in seawater, which matters for consistency and integrity. By delivering minerals exactly as they occur in nature, Quinton offers a simple, daily source of naturally balanced marine minerals that supports hydration and mineral intake in a form your body recognises.

Quinton was founded on the work of French biologist René Quinton, who in 1897 discovered that seawater closely mirrors human blood plasma. His research led to Marine Therapy, used in early European clinics to support cellular balance and vitality. Today, Laboratoires Quinton harvests seawater from protected vortexes in the Bay of Biscay and preserves its mineral integrity through gentle cold microfiltration. This careful formulation delivers naturally balanced, bioavailable minerals—helping you replenish what modern life depletes and restore everyday energy, resilience, and balance.
