Vitamin D3 from Lichen

Lichens are a complex life form consisting of a symbiotic relationship between a fungus and an alga. Lichens are a rare, plant-based source of Vitamin D3, the biologically active form of vitamin D. Most Vitamin D supplements are either animal-based or include the cheaper Vitamin D2. Studies have shown that Vitamin D3 may be more effective than D2 in raising and maintaining healthy serum Vitamin D levels.
