Dr.Tili's natural supplement of vitamin D from Icelandic lichen is undoubtedly one of the most appreciated for maintaining an efficient immune system and a healthy skeletal system . Those who choose a natural supplement of Vitamin D should always prefer those specific for Vitamin D3 . Why is this vitamin so important and how does it differ from the well-known vitamin D?
When we talk about vitamin D we are referring to a group of fat-soluble secosteroids (D1, D2, D3, D4 and D5) necessary for the intestinal absorption of minerals such as phosphate, calcium and magnesium. These elements are essential for the well-being of our skeleton and our immune system, but they require vitamin D3 to be absorbed by the body. In fact, vitamin D3 , transformed by the kidneys into calcitriol, is the active form of vitamin D. This exerts its biological effects by binding to the VDR, that is, a receptor found in the nucleus of many cells of the immune system (white blood cells, monocytes and T and B lymphocytes) and in those that make up the bones.
It is therefore vitamin D3 that activates the VDR in cells, contributing to the correct maintenance of calcium and phosphorus levels in the body and bones and to the preservation of a healthy immune system.
As crucial as it is, vitamin D3 is almost entirely produced by our body through the skin, through a chemical reaction that depends on exposure to sunlight (particularly UVB radiation). This causes a natural decline in its levels during the winter months, a time of year when our exposure to the sun is very low, which can lead to deficiencies in our immune system.
It is possible to replenish a part of the vitamin D3 that is not produced by the body through a balanced diet, but only a few foods can be considered good sources of vitamin D3 . For this reason, it is possible to use natural supplements based on Icelandic lichen , a particular symbiotic form between fungus and cyanobacteria that can live in extreme environments and accumulate large quantities of nutrients, in particular vitamin D and D3 .
The use of Iceland moss in the formulation of the natural supplement guarantees products with a high titration of vitamin D, and in particular vitamin D3. This makes it suitable for the care of bones and teeth and for maintaining a healthy immune system, especially for those who follow a vegan diet.
