Liposomal Pterostilbene 50% 70%

Pterostilbene — Liposomal Bulk Raw Material for Anti-Aging & Beauty

Liposomal Pterostilbene delivers a dimethoxylated analog of resveratrol that exhibits approximately 80% higher oral bioavailability and 4-7 times longer half-life due to its two methoxy groups replacing resveratrol's hydroxy groups. Extracted from Pterocarpus marsupium and encapsulated at 50% and 70% liposomal concentrations, pterostilbene activates SIRT1 at lower concentrations than resveratrol while simultaneously trapping reactive dicarbonyls to prevent glycation—a dual longevity-plus-glyco-defense mechanism that no other single ingredient provides.

Available Purity Grades

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

Why Choose Our Liposomal Pterostilbene?

• Superior Bioavailability: Two methoxy groups make pterostilbene approximately 80% more bioavailable than resveratrol, with a 7-hour half-life versus resveratrol's 1-2 hours, ensuring sustained tissue activity from a single dose.
• Enhanced SIRT1 Activation: Activates the SIRT1 longevity deacetylase at lower concentrations than resveratrol, modulating collagen gene expression and extending fibroblast replicative capacity with greater efficiency.
• Dicarbonyl Trapping: The stilbene double bond reacts with methylglyoxal and glyoxal, forming stable adducts that prevent these dicarbonyls from cross-linking collagen fibers through AGE formation.
• Anti-Glycation Gene Regulation: Downregulates RAGE receptor expression and upregulates glyoxalase-1 (GLO1), the enzyme that detoxifies methylglyoxal, providing both direct carbonyl trapping and enzymatic glycation defense.
• COX-2 Selective Inhibition: Preferentially inhibits COX-2 over COX-1, providing anti-inflammatory benefits without the gastric side effects associated with non-selective COX inhibition.
• Blueberry Consumer Appeal: Sourced from Pterocarpus marsupium but associated with blueberry-sourced pterostilbene in consumer awareness, offering brands a natural, fruit-derived positioning for marketing.

Target Applications

• Next-Gen Resveratrol Brands: Companies seeking to upgrade from resveratrol to a more bioavailable, longer-acting analog that also provides anti-glycation benefits beyond resveratrol's SIRT1 activation alone.
• Glyco-Defense Innovation Brands: Brands developing comprehensive anti-glycation products that combine carbonyl trapping, SIRT1 activation, and anti-inflammatory COX-2 inhibition in a single potent molecule.
