What is EirVit®?

EirVit® Vitamin D3 is Cholecalciferol from 100% Plant Phytosterol origin. Our high purity and quality Vitamin D3 ingredients are suitable for Vegans and Vegetarians, while meeting established regulatory requirements for Cholecalciferol.


Unlike Lanolin (and other) animal origin Vitamin D3, which is classified as a Product of Animal Origin (POAO), EirVit® Vitamin D3 does not have POAO import and export requirements such as Veterinary certificates.

Sources of Phytosterol

We obtain our Phytosterols from Pine Bark, ensuring a fully sustainable and responsible supply chain.


Our proprietary process firstly follows conversion of the Phytosterols into Cholesterol (to United States Pharmacopoeia (USP) and European Pharmacopoeia (EP) purity) and subsequent conversion into Cholecalciferol. The process is important in ensuring regulatory compliance.
