Vitamin D2 Ergocalciferol

Ergocalciferol (CAS 50-14-6), commonly sourced and traded as Vitamin D2, is a plant-derived form of vitamin D produced through UV irradiation of ergosterol. Viosterol and Deltalin are established market names recognized in pharmaceutical and nutritional supply chains. It functions as a bioactive nutrient supplement across food fortification, pharmaceutical dosage forms, and cosmetic preparations. In pharmaceutical manufacturing, it is used as the active ingredient in vitamin D deficiency treatments.

The material is formulated into capsules, tablets, and oral drops at defined potency levels. Food and beverage producers use Vitamin D2 to fortify dairy alternatives, cereals, and infant formula, where plant-based sourcing is a requirement. Cosmetic and personal care formulators incorporate it into skin-conditioning products targeting barrier support and nutrient delivery. Contract manufacturers in the nutraceutical sector use it to produce softgels and powdered blends.

Ergocalciferol is supplied as a crystalline powder or in oil-based dilutions standardized to defined IU/g potencies for easier handling and dosing accuracy. Recognized grades include USP, BP, and Ph. Eur. These standards support regulatory compliance across pharmaceutical and food applications. Resin-coated and spray-dried powder forms are available for dry-blend and fortification applications to ensure stability and performance.
