Quinton® Marine Therapy is based on a unique, centuries-old technique developed by biologist René Quinton in 1897, using pure seawater to support cellular health. Harvested from protected plankton blooms in the Bay of Biscay off the coast of France, this seawater is cold micro-filtered to preserve its therapeutic qualities. Quinton® supplements deliver up to 78 bioavailable minerals and trace elements, essential for maintaining the body's hydration, nutrient transport, and detoxification processes. Re-mineralisation with Quinton® supports overall wellbeing, helping to restore electrolyte balance, improve energy levels, and enhance immune function, making it a vital supplement for optimal health.

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.
