The origin of Vitamin D
The Icelandic Lichen (Icelandic Cetraria) also known as Arctic Lichen is a lichen belonging to the family of Parmeliaceae, whose vegetative body is called thallus.
Lichens are very particular plants, whose palate consists of the association of a mushroom and an alga, among which a collaborative relationship is defined as "mutual symbiosis" (from the Greek syn and bios = life together); This means that the two organisms live and grow by helping each other, and that one's life is closely linked and connected to the life of the other, with a mutual benefit.
The name lichen from the Greek λειχήν (leichén), from the root of λείχω (leicho), that is, "lambisco", for the smooth structure of the thallus.
Lichens were used by almost all populations of antiquity, especially as an emergency resource in case of famine (eg substitutes for cereal flour). They are also used as additives in the perfume and cosmetics industry.
In addition, lichenic substances also play a role outside symbiosis with man-made uses, such as:
- coloranti tessili
- usi alimentari
- antimutageni e antitumorali
Precisely for the extreme conditions in which it grows, Icelandic lichen develops a high number of nutrients, including Vitamin D, in the form of cholecalciferol (Vitamin D3), the most available form for the human body.
Vitamin D3 used by Diamond Life is extracted exclusively and exclusively from Icelandic lichens, grown in their natural environment and subjected to processes that are fully respectful of the environment.
