High Absorption Liposomal Pterostilbene Powder Trans-Pterostilbene Liposome Bulk Supply-1
High-Performance Phyto-Delivery
LIPOSOMAL
PTEROSTILBENE POWDER (50% / 70%)
Liposomal Pterostilbene Powder encapsulates high-purity Pterostilbene (CAS 537-42-8) — the dimethylated analogue of resveratrol with inherently superior metabolic stability — within a stable phospholipid bilayer structure. Available at 50% and 70% active loading grades, this ingredient transforms a poorly water-soluble crystalline compound into a water-dispersible, high-bioavailability delivery system for premium cognitive health and longevity formulations.
Lymphatic Uptake
Up to 70% Loading
TECHNICAL SPECIFICATIONS
LIPOSOMAL DELIVERY PRINCIPLE
Pterostilbene, despite its structural advantage over resveratrol (two methoxy groups conferring higher membrane permeability), remains practically insoluble in water and sensitive to oxidative degradation. Our liposomal process integrates pterostilbene into the lipid core of phospholipid vesicles through controlled emulsification and spray-drying.
The resulting liposome mimics the body’s natural lipid transport carriers, enabling absorption primarily via the intestinal lymphatic pathway — partially bypassing hepatic first-pass metabolism — while the phospholipid bilayer provides a physical barrier against light, oxygen, and moisture. The final powder combines the handling convenience of a dry ingredient with the water-dispersible performance of a liposomal delivery system.
KEY ADVANTAGES
Dual-Grade Flexibility (50% & 70%)
Two loading grades allow formulators to balance cost-per-active and dosage compactness across different product tiers.
Water Dispersibility
Converts the water-insoluble pterostilbene crystal into a readily dispersible powder, enabling stick packs, functional beverages, and effervescent formats.
Oxidation & Light Protection
The phospholipid bilayer shields pterostilbene from photodegradation and oxidation during manufacturing and shelf storage.
Lymphatic Absorption Pathway
Liposomal encapsulation aligns delivery with the body’s lipid absorption route, supporting more consistent systemic exposure.
EVIDENCE & LAB VERIFICATION
1. HPLC Active Assay
Every production batch undergoes HPLC analysis to confirm declared Pterostilbene loading (50% or 70%).
2. DLS Particle Size Analysis
Dynamic light scattering analysis verifies stable liposome formation within the 100nm–300nm range upon rehydration.
3. Encapsulation Efficiency (EE%) Reporting
Batch-typical EE% values (≥ 90%) are tested to confirm full encapsulation inside liposome vesicles.
4. Heavy Metal Inspection
Strict heavy metal test meets global supplement safety limits (Pb ≤ 10 ppm, As ≤ 1 ppm, Cd ≤ 1 ppm, Hg ≤ 0.1 ppm).
FUNCTIONAL ROLES
1. Cellular Longevity Pathway Support
Pterostilbene is recognized as a potent sirtuin-activating compound (STAC). Liposomal delivery maximizes absorption for premium anti-aging stacks.
2. Endogenous Antioxidant Defense Support
High-bioavailability polyphenol to activate the body’s internal antioxidant signaling network against free radicals.
3. Cognitive Wellness Support
Unique molecular structure supports healthy neuron activity, ideal for brain health & nootropic supplement formulas.
4. Metabolic Balance Support
Helps maintain balanced glucose metabolism and stable insulin sensitivity for metabolic support products.
INDUSTRIAL APPLICATIONS
1. Premium Longevity & Nootropic Capsules
70% high loading grade allows maximum active ingredient inside small compact capsules.
2. Functional Beverage Mixes & Stick Packs
Water dispersible liposomal powder works perfectly for instant drink sachets and soluble powder formulas.
3. Multi-Ingredient Brain Health Powders
Match with other nootropic raw materials for complex cognitive support blend supplements.
4. Soft Gel & Liquid Capsule Filling
Can be rehydrated into stable uniform suspension for liquid softgel encapsulation production.

TECHNICAL FAQ
Q1: How does liposomal pterostilbene compare to standard pterostilbene powder in formulation value?
A: Standard pterostilbene, despite inherently better membrane permeability than resveratrol, remains practically insoluble in water — limiting it to oil-based capsules. Liposomal encapsulation converts it into a water-dispersible form while utilizing the lymphatic absorption pathway for more consistent delivery.
Q2: Does the 70% loading grade affect dispersion or stability?
A: No — dispersion depends on phospholipid shell integrity, not active loading density. Both 50% and 70% grades pass the same DLS and EE% verification, confirming stable liposome formation upon rehydration.
Q3: What handling precautions are needed during manufacturing?
A: Blend at room temperature; avoid prolonged high-shear mixing. Keep compression force within standard range for tableting. Normal capsule filling machines work well. Store bulk goods in sealed nitrogen-filled containers away from light and heat.
