Description
Product Identity
High‑purity liposomal raw material derived from Polygonum cuspidatum root extract, standardized to 60% trans‑resveratrol, formulated with sunflower lecithin + phytosterols as the bilayer carrier system.
Delivered as an off‑white to light yellow free‑flowing powder with uniform liposome structure verified by TEM imaging, engineered for maximum oral absorption and formulation flexibility.
Absorption Breakthrough
Absorption Pain Point of Conventional Resveratrol
Bulk resveratrol suffers from extremely low water solubility, rapid hepatic metabolism, and poor membrane permeability. Most oral resveratrol is degraded before reaching target tissues, resulting in bioavailability below 1%.
Liposomal Absorption Breakthrough
Our liposomal delivery system fully encapsulates resveratrol within a phospholipid bilayer, shielding it from gastric acid and first‑pass metabolism.
This protective structure enables direct cellular uptake via lipid fusion, boosting bioavailability by 2–5x compared to non‑liposomal resveratrol powder.

FAQ
1. What makes your liposomal resveratrol different from regular resveratrol powder?
Our liposomal system encapsulates resveratrol to bypass solubility limits and metabolic degradation, delivering 2–5x higher bioavailability.
2. Which carrier system do you recommend for my supplement line?
Sunflower lecithin + phytosterols is recommended for best stability, clean label, and global market acceptance.
3. What is the difference between spray dried and freeze dried liposomal resveratrol?
Spray dried offers cost efficiency for mass production; freeze dried preserves maximum potency and liposome integrity.
4. How stable is your liposomal resveratrol during shipping and storage?
It remains stable for 24 months when stored sealed, cool, dry, and light‑protected; 2–8°C is optimal for long shelf life.
5. Can you provide full export documents for EU/US customs clearance?
Yes, we supply COA, TEM, COO, health certificates, and all required shipping documentation.
6. What types of finished products is this raw material best suited for?
It is ideal for capsules, tablets, solid drinks, gummies, and anti‑aging oral liquids.
7. Can you customize potency, particle size, or packaging for my brand?
Yes, we fully customize potency, carrier, process, particle size, format, and packaging to your specifications.
8. Is your liposomal resveratrol vegan, non‑GMO, and allergen‑free?
Yes, it is vegan, non‑GMO, soy‑free, dairy‑free, and free of common allergens.
