Vitamin D3 supplier and vitamin d3 manufacturer
Vitamin D3 powder bulk is a fat-soluble vitamin and a hormone precursor for calcium and phosphorus metabolism. Pure vitamin D3 powder is also known as "sunlight vitamin." Vitamin D powder is closely related to sunlight and can help us supplement our need for sunlight.
Vitamin D3 has evolved from a simple calcium absorption aid to a core immune modulator. Shaanxi Hongda supplies vitamin D3 using core "molecular-level microencapsulation" technology, ensuring that D3 particles are physically isolated in a protective matrix, providing you with industrial-grade raw material support characterized by "high stability, low loss, and compatibility with all dosage forms."

The best Cooperative Partner
1. Advanced Microencapsulation Technology:
Hongda utilizes fluidized bed microencapsulation technology to disperse Vitamin D3 within a starch or gelatin matrix, coated with an antioxidant protective film. Real-world testing shows that in accelerated stability tests at 40°C/75% relative humidity, our Vitamin D potency retention is over 35% higher than that of ordinary powders.
2. Exclusive CWD (Cold Water Dispersible) Specification:
Hongda offers a special CWD specification. These particles disperse instantly in cold water, forming a transparent, homogeneous, stable colloid without oil droplets or residue buildup, solving the challenge of applying Vitamin D's fat solubility in liquid formulations.

We offer classic products sourced from lanolin and vegetarian options from lichen/algae sources. All products are USP/EP certified and free of synthetic preservatives BHA/BHT, helping your brand establish a Clean Label advantage.
