Ingredient Profile
Vitamin D3 (Algae-Sourced)
Plant-based sunshine vitamin, engineered for stability and absorption.
100% Non-GMO, plant-based Vitamin D3 derived from microalgae, offering a clean, neutral-tasting alternative to conventional animal-derived D3. Micro-encapsulation technology protects the actIve ingredient against oxidation and moisture degradation, while enabling controlled release for enhanced intestinal absorption.
Overview
Vitamin D3 (cholecalciferol) is the physiologically active form of vitamin D used across the supplement, functional food, and pharmaceutical industries. As a vitamin D3 raw material supplier, Probionyx focuses on plant-based cholecalciferol — sourced from microalgae rather than lanolin (sheep wool), making it suitable for vegan, vegetarian, and halal/kosher-sensitive formulations.
The raw cholecalciferol oil is micro-encapsulated for handling, then standardized into cholecalciferol powder grades, most commonly supplied at 100,000 IU/g (0.25% D3) potency so formulators can dose precisely in tablets, capsules, sachets, and fortified foods. Encapsulation also protects the molecule against oxidation, moisture, and light degradation during storage and processing.
Because vitamin D3 supports calcium absorption while vitamin K2 (MK-7) directs that calcium to the skeleton, the two actives are frequently formulated together — see our Vitamin K2 (MK-7) ingredient page for combination guidance.

Applications
Frequently asked questions
Is your vitamin D3 suitable for vegan formulations?
Yes. Our cholecalciferol is derived from microalgae rather than lanolin, making it suitable for vegan, vegetarian, and religiously-sensitive formulations, subject to final certification by your manufacturing partner.
What does "100,000 IU/g" mean for formulators?
It describes the potency of the standardized cholecalciferol powder — each gram of powder delivers 100,000 IU of vitamin D3 activity — which lets formulators calculate precise per-dose inclusion rates for tablets, capsules, or fortified foods.
Why is vitamin D3 micro-encapsulated rather than supplied as raw oil?
Cholecalciferol oil is sensitive to oxidation, heat, and moisture. Micro-encapsulation creates a stable, free-flowing powder that protects potency through manufacturing, compression, and shelf storage.
Should vitamin D3 be formulated with vitamin K2?
Many bone and cardiovascular-health brands combine D3 with vitamin K2 (MK-7) because D3 increases calcium absorption while K2 helps direct that calcium to bone rather than soft tissue.
