Cat's Claw Elite®

Cat’s Claw Elite® stands out for its use of Quicksilver Delivery Systems® (QDS®), a premium liposomal delivery method that ensures high absorption and fast-acting support. The formula contains small, stable liposomes—measuring just 20–100 nanometres—that begin absorbing as soon as they enter the mouth. This bypasses much of the digestive process and delivers nutrients directly to the cells. The result is faster, more efficient uptake of immune-supportive ingredients so you feel the effects when you need them most.

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.
