Vitamin D

Vitamin D3 is primarily obtained from animal sources such as fish, dairy products, and eggs, while plants like lichens also contain vitamin D, though mostly in the less effective vitamin D2 form.
This particular vitamin, largely produced by sun exposure on the skin, plays a crucial role in the body. It not only acts as a vitamin but is also converted into a hormone
that regulates numerous bodily processes. Most cells in the body have receptors for vitamin D and rely on an adequate supply.
Vitamin D3, derived from lichens, supports the normal function of the immune system, contributes to the maintenance of normal bones, muscles, and teeth, and promotes regular calcium absorption as well as normal
calcium levels in the blood.
