Product Information
Vitamin D2 (Ergocalciferol) Powder at a Glance
Use these identity and grade details to match the offered material with your formulation brief and purchasing specification.
Formulazione
Formulating with Vitamin D2 100 CWS Powder
Beyond the assay, formulation teams should assess the delivery system, distribution at low inclusion rates and suitability for the intended process.
Active Form
Vitamin D2 is the ergocalciferol form of vitamin D, distinct from cholecalciferol (D3). Confirm that the finished-product brief specifically calls for D2; botanical or mushroom origin cannot be established from the assay alone.
Carrier and Formulation
A CWS designation describes the formulated ingredient format, not a complete carrier declaration. Request the composition and allergen information needed to assess label suitability and compatibility with other ingredients.
Use in Dry Blends
At low inclusion rates, premix design and blending sequence can affect distribution. Check homogeneity with the actual batch size and equipment rather than assuming a dry powder will distribute uniformly.
The designation CWS refers to the powder format; it does not establish the exact carrier composition or guarantee full dissolution in water. Product-specific dispersion information can be requested for formulations where this is important.

Applicazioni
Applications for Ergocalciferol 100 CWS
The use case determines which checks matter most: dose distribution in supplements, homogeneity in premixes, reconstitution in nutrition powders or regulatory eligibility in fortified foods.
Ergocalciferol Supplements
For capsules and tablets specifying ergocalciferol, translate the target IU per serving into an appropriate addition rate. Verify blend uniformity and finished-product assay, especially when the vitamin is added at low levels.
Nutrient Premix Manufacturing
For multi-ingredient premixes, consider ingredient segregation, blending order and dilution strategy. Trial the powder in the actual carrier matrix and confirm homogeneity before scaling production.
Powdered Nutrition Formulas
For drink mixes and powdered nutrition products, evaluate how the formulated powder behaves during reconstitution and storage. The CWS designation alone should not be treated as proof of complete water solubility.
Food Fortification Projects
For fortified foods, first verify that ergocalciferol is permitted for the target category and destination market. Then assess process exposure, ingredient declaration and the intended fortification level.

Immagazzinamento
Keep tightly sealed in a dry place, protected from light. Recommended storage temperature: below 25°C.
Product Documentation
Request a lot-specific COA and the current specification for supplier qualification. Review the acceptance limits against your internal requirements; batch results may differ from the example COA.
Fonte e composizione
Origin and carrier details should be verified through the applicable supplier declarations. Do not infer mushroom origin, vegan suitability or allergen status from the term ergocalciferol alone.
Bulk Supply
Commercial terms, available pack sizes, lead time and shipment arrangements depend on the requested order and destination; confirm them with the quotation.
