Pharmaceutical-Grade Liposome Vitamin C Powder: A Revolution in Bioavailability Based on Ultrasonic Microencapsulation Technology
Shaanxi Hongda Phytochemistry Co., Ltd. is one of China's most reliable manufacturers and suppliers of Liposomal Vitamin C Powder Bulk. You are welcome to wholesale large quantities of Vitamin C phospholipid liposomes from our factory. For any questions regarding quotations and free samples, please feel free to email us:
Shaanxi Hongda employs a core "thin-film hydration-ultrasonic nano-shearing" coupling process, utilizing a phospholipid bilayer to encapsulate Vitamin C, forming tiny vesicles similar to cell membranes. A unique low-temperature spray drying technology is then used to transform it into a stable powder, ensuring the raw material effectively resists stomach acid before entering the intestines, resulting in 6-10 times the effect of ordinary Vitamin C. Liposome Vitamin C can directly deliver Vitamin C to cells, increasing intracellular Vitamin C concentration and enhancing the body's antioxidant and immune support.
Why do top global brands choose Shaanxi Hongda?
1. Nanoscale Particle Size Control: We use Dynamic Light Scattering (DLS) detection to ensure an average particle size between 100-250nm and a polydispersity index (PDI) < 0.25, exhibiting extremely high stability and excellent absorption consistency.
2. Premium Phospholipid Source: We uniformly use non-GMO sunflower seed phospholipids, vitamin C, and acid-treated starch, completely eliminating allergen risks and GMO concerns, achieving a clean product.
3. Extremely High Encapsulation Rate: Utilizing our exclusive encapsulation technology, our measured encapsulation rate is greater than 90%, making it very gentle on the digestive system.
4. Guaranteed Supply Chain: As a source factory with over 25 years of extraction experience, we currently maintain a stock of 15 tons of liposome series products.

Functions of Liposome Vitamin C:
1. Precise Strengthening of the Immune System
Liposome Vitamin C powder, in bulk form, utilizes the affinity of the phospholipid bilayer to directly reach lymphocytes and phagocytes, activating the fighting power of white blood cells at the first moment of pathogen invasion. This "intracellular delivery" mode significantly shortens the immune response cycle, and combined with the increased antibody production rate, builds a highly dynamic biological defense barrier for the body.
2. Deep Cellular Antioxidant Effects
Unlike ordinary vitamin C, which is easily oxidized extracellularly, Hongda's liposome technology endows it with "antioxidant nuclear bomb" properties, inhibiting the chain damage caused by oxidative stress at its source, and deeply helping to lighten pigmentation and improve dull skin texture.
3. UV Protection
Vitamin c liposomal powder is a core driving force for collagen synthesis. In vivo, it mimics biomembrane fusion, continuously delivering active antioxidant molecules to the dermis, inducing fibroblasts to produce high-quality collagen fibers, repairing damaged elastic fibers, and giving the skin a firm and radiant appearance from the inside out.
4. Vascular Endothelial and Circulatory System Optimization
For cardiovascular health, liposomal c powder can intercept the oxidation process of LDL, blocking the initial chain reaction of plaque formation at its source, improving smooth muscle flexibility and lipid metabolism efficiency, and promoting blood circulation.
5. Blood-Brain Barrier Penetration and Neurological Repair
Powdered liposomal vitamin c acts as a "metabolic waste scavenger" in the brain, clearing oxidative residues from neuronal firing. It also stabilizes the emotional center and enhances cognitive sharpness.

Why Choose Us? --- Your Global Bioavailability Compliance Partner
1. Certification Guarantee:
Shaanxi Hongda factory has passed ISO22000, FSSC, Halal, Kosher, and US FDA molecular identification registration.

2. R&D Backing:
Hongda factory has an independent liposomal vitamin c powder R&D laboratory, supporting customized development for special carriers (such as liposomal iron, liposomal glutathione, liposomal berberine, liposomal curcumin, etc.).

3. Transparent and Traceable:
From sunflower seed raw materials to final spray drying, each batch has a complete batch record available for auditing.

FAQs:
Q1: Will the liposomal vitamin c powder separate into layers after dissolving in water?
A: Our powder has excellent water reconstitution properties. Because the particles undergo nano-sizing, they dissolve into a translucent microemulsion, avoiding the oil-water separation or residue buildup common with ordinary phospholipids, making them ideal for ready-to-drink powder packets.
Q2: How do you know it's liposomal vitamin c rather than simply a standard mixture?
A: In addition to HPLC data, we can supply TEM (transmission electron microscopy) photos upon request, which clearly reveal the spherical bilayer vesicle structure.
Q3: How is delivery time guaranteed?
A: Shaanxi Hongda implements a "pre-production scheduling plan," allowing for priority production and shipment for orders placed as early as possible.
