1️⃣ Introduction to Vitamin D3

Vitamin D3 (cholecalciferol) is a fat-soluble vitamin that plays a crucial role in calcium absorption, bone health, immune function, and muscle strength. It is naturally synthesized in the skin through sun exposure but is often supplemented due to limited sunlight exposure and dietary deficiencies.

At Chibio Biotech, we provide premium-quality Vitamin D3 Powder in two concentrations:

• Vitamin D3 Powder 100,000 IU/g
• Vitamin D3 Powder 500,000 IU/g

Both grades are food-grade, stable, and suitable for various formulations​​.

Source:

Chibio Biotech’s Vitamin D3 Powder (100K IU/g & 500K IU/g) is derived from lanolin (sheep wool grease). This source is widely recognized as the most bioavailable and effective form of Vitamin D3, as it is identical to the cholecalciferol naturally synthesized by human skin when exposed to sunlight.

While there are plant-based Vitamin D3 sources (such as lichen-derived D3), Chibio Biotech’s current Vitamin D3 powder offerings are primarily lanolin-derived, ensuring high purity, stability, and compliance with USP/EP standards​​.

If you require plant-based Vitamin D3, please let us know, and we can explore solutions to meet your specific needs! 🌱✨
