Biocidin® LSF

Biocidin® LSF stands out through the use of Quicksilver Delivery Systems® (QDS®), which ensures high absorption via ultra-small liposomes—measuring just 20–100 nanometres. These liposomes begin absorbing upon contact in the mouth, bypassing digestion and delivering active botanicals directly to the cells. This allows for rapid, effective support in promoting microbial balance, detox, and immune function throughout the body.

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.
