High Absorption Liposomal Pterostilbene Powder Trans-Pterostilbene Liposome Bulk Supply
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.
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 reported to confirm genuine encapsulation within the liposome structure.
4. Heavy Metal Screening
Rigorously monitored to comply with global safety standards (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 enhances its suitability for premium "longevity stack" formulations.
2. Endogenous Antioxidant Defense Support
Functions as a highly bioavailable polyphenol that supports the body's internal antioxidant signaling networks.
3. Cognitive Wellness Support
Pterostilbene's structural characteristics support healthy neuronal function, making it a key active in nootropic and brain-health formulations.
4. Metabolic Balance Support
Contributes to maintaining healthy glucose metabolism and insulin sensitivity pathways.
INDUSTRIAL APPLICATIONS
1. Premium Longevity & Nootropic Capsules
Primary application for the 70% grade, enabling maximum active density in compact capsule formats.
2. Functional Beverage Mixes & Stick Packs
Water-dispersible liposomal powder uniquely suited for pterostilbene-fortified sachets and functional drink powders.
3. Multi-Ingredient Brain Health Powders
Ideal for premium nootropic blends, greens powders, and cognitive-support formulations.
4. Soft Gel & Liquid Capsule Filling
Can be reconstituted into a stable suspension for liquid-fill softgel applications.

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 forces within standard ranges for tableting. Standard capsule filling is fully compatible. Store bulk in sealed, nitrogen-flushed containers away from light and heat.
