Bitter X

Quicksilver Scientific sets a new standard for dietary supplements by being the first to use nanoparticle delivery at a pharmaceutical level with their Quicksilver Delivery Systems®️ (QDS®️). Their unique formulation features small liposomes (20-100 nanometers) that are stable enough to navigate between cells. This size ensures they begin absorbing as soon as they enter the mouth, maximising bioavailability before they can be affected by the digestive process. Additionally, as an SGS-certified cGMP manufacturer, they guarantee rigorous in-house and third-party testing for every product, ensuring its safety and efficacy. Experience the Quicksilver difference with the Bitter X supplement to support your 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.
