D - Organic Vegan vitamin D 1000iu 60 tablets from organic mushrooms | discontinued

Vitals Vitamin D2 from organic mushrooms
Organically cultured mushrooms were used for this supplement. Mushrooms contain various nutrients among which ergosterol (provitamin D2) which will convert into ergocalciferol (vitamin D2) when enough UV-rays fall onto the mushrooms.
Most mushrooms are grown in the dark, so don't expect mushrooms that you can buy from the greengrocer, to contain significant amounts of vitamin D.
By contrast, the mushrooms used for this extract have been exposed to enough UV-rays and therefore contain a high amount of vitamin D2.

Advantages of vitamin D from mushrooms
An advantage of using vitamin D from mushrooms is how this is an entiurely natural and plant-based product as opposed to vitamin D3 products that are derived from animals (sheep wool or fish livers) and require more purification.
This makes it suitable for vegetarians and vagans as well as for people who prefer a more natural ‘whole food’ supplement instead of a supplement with just one singular isolated compound.

Unfortunately it is not yet possible to create vegan organically certified vitamin D3. .

Vitamin D2 as alternative to vitamin D3
Vitamin D2 is converted into calcitrol, which is the bioactive form of vitamin D in the body. Formerly it was thought how vitamin D2 (the plant-based form of vitamin D) is less effective as a supplement than vitamin D3 (the animalic form) , but a few recent studies that were done on this specific organic vitamin D from mushrooms, show plant-based vitamin D2 can be an excellent alternative to vitamin D3 and is suitable to increase and maintain a normal status of vitamin D in the body. 

Mechanism of vitamin D
Vitamin D is very important for proper calcium absorption and by consequence also for bone metabolism and strong teeth.
It also has a main role in a proper functioning immune system and normal cell replication.
An optimal vitamin D intake is also crucial for cardiovascular health.
Babies, children and pregnant women need to ingest enough vitamin D for proper growht and development.
In winter, the body's own production of vitamin D is much lower than in summer.
Also, with advancing age, our bodies cannot produce enough vitamin D on its own.

Organic
The active ingredients from organic nutritional supplements are guaranteedto be organic and not being produced in a synthetic way. Apart from this, production takes place with special regard to the environment, animals and humans. Special protocols outline what is meant by this. For instance, no chemical pesticides, fertilizers or genetically modified organisms are being used.
The Dutch institute Skal Biocontrole checks whether the protocols are being followed to ensure a product is truly organic.
