For this product are organically grown champginons used. Mushrooms contain many different nutrients, including ergosterol (provitamin D2) which is converted under the influence of sufficient UV light (eg the sun) is ergocalciferol (vitamin D2).
Most mushrooms are grown in the dark, however, so the mushrooms in the shops often do not contain significant amounts of vitamin D. The mushrooms in this product are well exposed to UV light and therefore have a high content of vitamin D2.
An advantage of this vitamin D from fungi is that this is a completely natural and vegetable-based product, as opposed to vitamin D3-products of animal source (schapenwolvet or fish liver) have been obtained and which require more processing steps. This makes this product suitable for vegetarians and vegans, and for those who prefer to opt for a natural "whole food" supplement rather than a supplement with an insulated fabric.
It is currently not possible to produce. (Vegetable) certified organic vitamin D3
Vitamin D2 is converted by the body to calcitriol, the active form of vitamin D in the body. Previously it was thought that vitamin D2 (the plant form of vitamin D) was less effective than vitamin D3 supplement (the animal form), but a number of recent studies (done include these specific biological vitamin D from mushrooms) show that plant Vitamin D2 is a great alternative may be to put the blood on and steady.
