Other names
Due to its resemblence to antlers, Cladina rangiferina is often called Reindeer lichen, grey reindeer lichen, and reindeer moss. Despite the common name “reindeer moss”, it is a lichen rather than a moss.
What is lichen?
Lichen is a naturally occurring partnership between a fungus and a photosynthetic organism, usually an alga and/or cyanobacterium. The fungus provides structure and protection, while the photosynthetic partner produces nutrients through photosynthesis. Cladonia rangiferina is a pale, branching species commonly found in open, nutrient-poor environments, particularly in northern and tundra regions.
What is it used for?
Cladonia rangiferina is a rich, non-animal source of vitamin D3 (cholecalciferol). Research has identified naturally occurring vitamin D3 in reindeer lichens, and lichen-derived D3 is now used as a vegan alternative to D3 traditionally sourced from lanolin (from sheep's wool). Vitamin D helps regulate calcium and phosphate in the body and contributes to the maintenance of normal bones, teeth and muscle function. It also contributes to normal immune function.
