Overview

Product Overview & Core Technical Identity

SUNWAY supplies premium Cholecalciferol (Vitamin D3) 100,000 IU/g CWSS microencapsulated beadlet powder sourced from NHU COVITAS, fully compliant with GB 1903.50-2020, USP and FCC standards. This spray-dried cold-water soluble powder adopts safe starch wall material with built-in natural tocopherol antioxidant, completely isolating fat-soluble D3 active core from light, heat and oxygen to greatly boost processing and storage stability. It features excellent free-flow property, uniform particle grading and instant dispersion in aqueous systems, solving the water insolubility and easy degradation drawbacks of raw vitamin D3 oil. Every batch completes full HPLC potency and microbial comprehensive testing, with 12-month sealed sample retention to realize full quality traceability. Mixed consolidated shipment with microencapsulated VA, VE and B-group vitamins is supported to reduce clients' integrated procurement & logistics costs.

Functions

Physiological Functions & Industry Application Logic

Microencapsulated Vitamin D3 100K retains complete biological activity of cholecalciferol, overcoming the water-insoluble and photo-sensitive defects of pure VD3 oil via spray-dried microcapsule coating technology:

Calcium & Phosphorus Absorption Regulator Core nutrient for bone health; promotes intestinal calcium and phosphorus uptake, prevents childhood rickets, adult osteomalacia and elderly osteoporosis, mandatory fortifier for infant milk powder and bone-care nutritional products under WHO micronutrient guidelines.

Immune System Modulator Regulates differentiation of immune cells, enhances body's defense against viral and bacterial infections, reduces cold and inflammation risks for children, pregnant women and seniors.

Muscle Strength & Neural Maintenance Relieves muscle weakness, soreness and limb numbness caused by VD3 deficiency, improves exercise endurance and daily mobility for middle-aged and elderly groups.

Unique Dry Processing Stability Advantage Starch microcapsule shell forms physical barrier against light & oxygen, maintains full VD3 potency during spray drying, baking and long-term shelf storage; cold-water dispersible property enables direct addition to milk, drinks and solid powder without oil emulsifier.

Livestock & Aquatic Breeding Booster Improves poultry eggshell hardness, piglet bone development and fish skeletal growth, reduces juvenile mortality and breeding stress response, widely added into animal feed premixes.

Key Property Reminder: Raw cholecalciferol is extremely light-sensitive; though microcapsule coating greatly improves stability, unpacked long-term exposure to strong light or temperature over 60C will rupture the shell and trigger potency decline.
