Consumption of mushrooms can ensure the supply of large amounts of vitamin D. For this purpose, however, they should be placed in the sun for half an hour before consumption.

Like human skin, fungi synthesize vitamin D under the influence of ultraviolet light , even after being cut from the root.

30 people took part in the study. They are divided into two groups. For a period of 12 weeks, the volunteers of the first group took vitamin D supplements , and the second group exposed to the sun mushrooms in powder form.

The results show that both groups have significantly increased their vitamin D levels. The researchers explained that this was evidence that eating mushrooms that had been exposed to the sun before eating had the same effect as taking supplements. Mushrooms , unlike supplements, have other positive effects on the body.


Researchers have found that sun-absorbing mushrooms also contain vitamin D2 , which also has a positive effect on raising and maintaining normal levels of vitamin D. D2 is not produced in vertebrates and is obtained through plant-based foods and mushrooms.

According to experts, heat treatment of mushrooms does not harm the vitamin content, it is even possible to improve its absorption by the body.

The results of the study are published in the journal Dermato-Endocrinology .
