Of the many lichens which particular one is it please? Is it of the fruticose or foliose variety? (I assume it is not of the crustose category).
I wanted to know if it is a particular lichen (of many) that you use. Or do all lichen contain vitamin D3?
Hi, we don't disclose the specific lichen source for confidentiality-reasons (we do of course to regulators). It is a species with established food use, and we only found a single strain propagates meaningful quantities of D3. The growing location, altitude, UV levels are all vital for yield.
