Lichen Versus Lanolin Sources

Most commercial vitamin D3 comes from sheep lanolin washed with harsh detergents and irradiated. Wild lichen provides identical cholecalciferol directly from a non-animal, sustainably harvested symbiotic organism.

Testing for Botanical Identity

Lichen harvesting requires strict ecological oversight to prevent forest floor depletion. Clean manufacturers check for heavy metals and pesticide drifts that settle on wild-growing lichens.

• Identity verification: Gas chromatography mass spectrometry confirms D3 molecular structure.
• Heavy metal screen: Lead and cadmium thresholds must test below 0.01 parts per million.
• Organic carrier base: Dissolved in non-hydrogenated plant medium-chain triglycerides for stability.

Reading the Label

Check for Cladonia rangiferina on the label. Confirm that the finished formula contains no animal byproduct derivatives, no synthetic preservatives, and zero artificial colors.
