Conventional Lanolin Supply Chain
- Source context is often hidden behind technical naming.
- Animal-origin input from sheep-wool grease processing.
- Consumer trust depends on assumptions, not visible data.
The Science of Purity
The "Sheep Grease" Truth
Most conventional vitamin D3 is produced from lanolin, a waxy grease extracted from sheep's wool and heavily processed before conversion into cholecalciferol. We built a cleaner path using plant sterols and sunlight-mimicking chemistry.
PurePlantD3® Plant-First Standard
- Pine-derived sterols as the starting source.
- Sunlight-mimicking conversion into bio-identical C27H44O.
- Batch-level COA verification available to the customer.

What the Industry Does
Lanolin-derived D3 is legal and common, but most labels never explain the origin path in plain language. That opacity is exactly what creates consumer confusion.
Our position is direct: if sourcing details feel uncomfortable to disclose, they should be improved—not hidden.
- Lanolin is a wax from sheep-wool processing.
- Conventional supply chains often mask source context behind technical naming.
- Customers deserve source transparency before they buy.
Our Alternative
PurePlantD3® starts with botanical sterols and a controlled UV-driven conversion process. The endpoint is still cholecalciferol (C27H44O), but with a plant-first sourcing philosophy.
This allows us to deliver the same biologically familiar molecule while aligning with vegan expectations and cleaner sourcing standards.
Truth Over Hype
We do not ask for blind trust. We publish our standards, explain our processing logic, and provide batch-level documentation through the COA portal.
