Liposomal Isoquercetin 50% 70%

Isoquercetin (Quercetin-3-O-glucoside) — Liposomal Bulk Raw Material for Anti-Aging & Beauty

Liposomal Isoquercetin delivers the glucose-conjugated form of quercetin, which exhibits dramatically superior bioavailability compared to standard quercetin aglycone. The attached glucose molecule allows active transport via sodium-dependent glucose transporters (SGLT1), bypassing the efflux pumps that limit quercetin absorption. Produced by enzymatic conversion from rutin and encapsulated at 50% and 70% liposomal concentrations, isoquercetin inherits all of quercetin's MMP-inhibitory and anti-inflammatory properties while being significantly more effective at reaching target tissues.

Available Purity Grades

• Isoquercetin 50% 70% (HPLC) — Liposomal powder with phosphatidylcholine encapsulation for enhanced bioavailability.

Why Choose Our Liposomal Isoquercetin?

• Enhanced Bioavailability: The glucose moiety enables SGLT1-mediated active transport, achieving 2-3 times higher plasma concentrations than equivalent doses of standard quercetin aglycone.
• MMP-1 and MMP-3 Blockade: Inhibits collagenase and stromelysin expression through the same NF-κB and AP-1 signaling pathways as quercetin, but at lower effective concentrations due to better tissue penetration.
• Anti-Glycation Activity: Traps reactive dicarbonyl species including methylglyoxal and glyoxal before they can cross-link collagen fibers, preventing the formation of stiff, yellow AGEs in the dermal matrix.
• Skin Barrier Fortification: Upregulates filaggrin and loricrin expression in the stratum corneum, strengthening the skin barrier against environmental aggressors and reducing transepidermal water loss.
• Vascular Health Support: Improves microvascular endothelial function in dermal capillaries, enhancing nutrient and oxygen delivery to skin cells for better overall complexion and radiance.
• Nano Liposomal Format: At 50% and 70% liposomal loading with nanometer-range vesicle size, isoquercetin achieves deeper dermal penetration than conventional powder-based quercetin formulations.

Target Applications

• Advanced Delivery Brands: Companies developing nano-liposomal anti-aging formulations that emphasize enhanced bioavailability and deeper dermal penetration for superior clinical results.
• Nutricosmetic Innovation Brands: Brands creating next-generation oral beauty supplements that pair isoquercetin's superior absorption with complementary actives for systemic skin protection.
