Product Description
Vitamin D3, also known as Cholecalciferol, is the biologically active form of Vitamin D synthesized in the skin upon UV exposure. As a critical regulator of calcium and phosphorus homeostasis, it is essential for skeletal integrity and immune modulation.
At Wellgreen, we provide a versatile range of Vitamin D3 powder and crystal forms designed to meet the rigorous demands of the nutraceutical and food industries. Our Cholecalciferol is sourced from high-quality lanolin and processed using advanced micro-encapsulation and stabilization techniques. This ensures that the delicate Vitamin D3 molecule remains potent throughout the manufacturing process and shelf life, delivering consistent Vitamin D3 benefits for bone density, dental strength, and cellular health support.
