Key Benefits

  • Supports gentle detox and hydration.

  • Aids digestion and mineral balance.

  • Provides up to 78 ionic trace elements.

  • Promotes relaxation and restful sleep.

QuintEssential® 0.9 Sachets deliver a pure, isotonic blend of ocean minerals and alpine spring water, formulated to match the mineral concentration of human blood plasma. This solution supports cellular hydration, homeostasis, and gentle detoxification while promoting overall balance and relaxation.

Sourced from protected ocean blooms off the coast of France, this seawater solution is harvested following the original guidelines of biologist René Quinton and cold-sterilised to retain its natural properties. Each sachet provides up to 78 highly bioavailable ionic minerals, offering broad-spectrum support for digestive health, mineral replenishment, and nervous system function.

With daily use, QuintEssential® 0.9 can help nourish your body at the cellular level, contributing to better hydration, improved digestion, and a calm, restored state of wellbeing.

QuintEssential® 0.9 stands out for its use of Quinton’s Marine Therapy, a cell-nourishing technique developed in 1897 by French biologist René Quinton. This protocol uses seawater to help maintain the hydromineral balance of cells, supporting optimal health through natural mineral replenishment. The result is a therapeutic marine solution uniquely aligned with the body’s internal environment.

Since 2006, Quicksilver Scientific has redefined liposomal supplementation, driven by a mission to solve the bioavailability problem and deliver on the promise of natural health. It all began with Dr. Chris Shade’s quest to overcome his own mercury toxicity. Frustrated by ineffective traditional nutrient delivery methods for glutathione, he turned to liposomal technology to enhance absorption. Discovering the low quality of existing products, he crafted his own, mastering the principles of nutraceutical liposomes and creating their flagship Liposomal Glutathione. Today, Quicksilver Scientific offers science-backed, high-bioavailability supplements and synergistic formulas, along with valuable education for optimal health and wellness.
