A vitamin D deficiency is quite common and is mostly caused by limited exposure to sunlight. Besides that, there are common genetic variants in vitamin D metabolism that can also contribute to a functional deficiency.
Vitamin D is a vitamin and at the same time a prohormone. Vitamin D3 is important for many body functions, like:
Normal functioning of the immune system;
Normal blood calcium levels;
The maintenance of normal and healthy bones/teeth;
The maintenance of normal muscle function.
Yes, it is. Our Vitamin D is derived from lichen, that combined with v-caps made from cellulose makes our Vitamin D 100% suitable for vegans.
Our Vitamin D is developed to raise people’s blood levels to adequate values. Therefore it is not advised to take it continuously for long periods without having your blood levels checked, as with other more standard vitamin D supplements. It’s better to see this supplement as a vitamin D boost. The time period to get your levels high enough will vary from person to person, but is mostly within 1 to 4 weeks if taken continuously. If you do not have any blood work done, we advise against taking this supplement continuously for longer periods.
