Longevity Elite™

Longevity Elite™ stands out for its use of Quicksilver Delivery Systems® (QDS®), a liposomal technology that ensures superior absorption and bioavailability. The formula features ultra-small, stable liposomes—20–100 nanometres in size—that begin absorbing as soon as they enter the mouth. This helps nutrients bypass digestive breakdown and reach cells efficiently, delivering fast and effective age-optimising support.

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.
