1. Product Identity
Liposomal Vitamin D3 50000IU/G Powder
Active Ingredient: Vitamin D3 (Cholecalciferol)
Potency: 50000 IU per gram
Form: Liposomal powder
Carrier System: Sunflower Lecithin + Phytosterols (Non‑GMO, Vegan, Soy‑Free)
2. Absorption Breakthrough
Traditional Vitamin D3 Limitations
- Poor water solubility
- Sensitive to stomach acid
- Low and inconsistent oral bioavailability
- Easy to degrade during digestion
- High loss before entering systemic circulation
Liposomal Absolution Solution
Our liposomal delivery uses a phospholipid bilayer structure to encapsulate Vitamin D3, shielding it from gastric acid and enzymatic breakdown. It directly enters the intestinal lymphatic pathway, increasing bioavailability by 2–5 times compared to conventional D3 powder.
3. Carrier & Technology
Three Optional Carrier Systems
- Sunflower Lecithin (Non‑GMO, Vegan, Soy‑Free)
- Sunflower Lecithin + Phytosterols (enhanced stability & dispersion)
- Sunflower Lecithin + Cholesterol (max loading efficiency)
Two Professional Drying Technologies
- Spray Dried: balanced flowability, cost-efficient, ideal for mass production
- Freeze Dried: ultra‑high vesicle integrity, superior stability, premium formulation grade
Liposomal Mechanism
Phospholipids form nano‑vesicles that fully wrap Vitamin D3, protecting against oxidation, light, heat, and stomach acid to ensure intact and efficient absorption.

8. FAQ
What is Liposomal Vitamin D3 50000IU/G?
It is a nano‑encapsulated D3 powder with 50000 IU per gram, carried by sunflower lecithin and phytosterols for greatly improved absorption.
How does liposomal technology enhance D3 absorption?
Liposomes protect D3 from stomach acid and deliver it via lymphatic circulation, reducing loss and raising bioavailability by 2–5 times.
What is the main difference between liposomal D3 and regular D3 powder?
Liposomal D3 offers better water dispersibility, higher stability, lower degradation, and much higher absorption efficiency.
Which drying processes do you provide?
We offer spray drying (cost‑effective) and freeze drying (high‑stability) to meet different formulation requirements.
What certificates and export documents are available?
We supply COA, HPLC, TEM, COO, Health Certificate, and complete export declaration support.
What customization options do you offer for liposomal D3?
Potency, carrier, production process, particle size, powder characteristics, and packaging can all be customized.
What finished products can this liposomal D3 be applied to?
It is widely used in solid drinks, capsules, tablets, gummies, premixes, and functional foods.
How should I store this product and how long is the shelf life?
Keep sealed in cool, dry, dark conditions; 2–8°C for long‑term storage. Shelf life is 24 months when properly stored.
