Key Benefits
Start your day with a wave of natural minerals. QuintEssential® 0.9 Sachets blend pure ocean minerals and alpine spring water, carefully balanced to mirror the mineral concentration of your blood plasma. This isotonic solution is designed to help you stay hydrated and maintain your mineral intake, supporting your body’s natural balance.
Each sachet is sourced from pristine ocean waters off the coast of France, following the original methods of biologist René Quinton. The cold-sterilisation process preserves the natural properties of the minerals, delivering up to 78 ionic trace elements in every serving.
Whether you’re looking to replenish minerals after exercise or simply want to support your daily hydration, QuintEssential® 0.9 offers a simple way to nourish your body as part of a balanced lifestyle.
