Vitamin D Mushrooms

Luxidum offers fully automated customised Vitamin D-Boosters for the production of Vitamin D Mushrooms – the most innovative step forward in fresh mushroom products.

In 2016 Monaghan Mushrooms was granted the first authorisation for UV-treated Vitamin D button mushrooms as a Novel Food.

Since then, Walsh Mushrooms and Banken Champignons applied for authorisation through a costly and time-consuming application process.

However, the Novel Food regulation amendment (EC) No 2015/2283 became valid on 1.1.2018. All foods mentioned in the Novel Food Union List can now be placed on the EU-market by every company without any further authorisation process!

Vitamin D Deficiency

Dietary vitamin D intake from commonly consumed foods is generally low. According to the German Nutrition Society, adults typically obtain approximately 2–4 µg of vitamin D per day from food. Vitamin D status, however, also depends substantially on endogenous synthesis in the skin following exposure to sunlight.

As only a limited number of foods naturally contain relevant amounts of vitamin D, UV-treated mushrooms can provide an additional food source of vitamin D2.

Vitamin D Sources

Few foods are naturally rich in vitamin D. Good sources include fatty fish such as salmon and tuna.

However, all mushroom species contain ergosterol, and upon exposure to UV light from the sun or artificial light, this provitamin D is converted through a photochemical reaction to vitamin D.

That´s why wild mushrooms can contain high amounts of vitamin D due to sunlight exposure. On the other hand, the vitamin D content of cultivated button mushrooms is minimal (<0.2 μg/100 g), because they are cultivated indoors without the benefit of sunlight.

EU-authorised claims for vitamin D

The following health claims are authorised in the European Union for vitamin D. They may be used for a particular food, including qualifying vitamin D mushrooms, only if all applicable conditions of Regulation (EC) No 1924/2006 and Regulation (EU) No 432/2012 are met. These claims are authorised for vitamin D and do not constitute an EFSA approval of a particular mushroom product.

Nutrition Claims

  • Source of vitamin D
  • High in vitamin D

Health Claims

  • the normal function of the immune system
  • the maintenance of normal bones
  • the maintenance of normal muscle function
  • the maintenance of normal teeth
  • normal absorption/utilisation of calcium and phosphorus
  • normal blood calcium levels
  • has a role in the process of cell division
We offer Vitamin D-Boosters with different UV light technologies based on customer-specific requirements eg. pulsed UV light from Xenon or continuous UV light from mercury bulbs. Our aim is to offer stepfree adjustability of your mushrooms’ desired vitamin D content from 1 – 30 μg/100 g at the stage of end-customer sales together with very good reproducibility.

About the Founder

  • Dr. Paul Urbain is a pioneer in the field of “Vitamin D Mushrooms” research. As a nutritional scientist, he was in 2011 the first to demonstrate in humans that the bioavailability of vitamin D from UV-treated and vitamin D-rich button mushrooms can effectively cure vitamin D deficiency [1].
  • Since 2011 he has held the utility patent for the use of Vitamin D Mushroom Powder in different food products and supplements.
  • He recently directed a subproject entitled: “Exploration of novel vitamin D-enriched mushrooms and powdered mushroom-containing food products for prevention of vitamin D deficiency; efficacy and safety” within the EU’s 7th Framework Programme (ODIN) [2-4].
  • The project partner Monaghan Mushrooms of Ireland got in 2016 the first authorisation of UV-treated and vitamin D-rich button mushrooms as a Novel Food.
  • In 2017, he submitted on behalf of a large producer of button mushrooms in Germany, an application for authorisation to put Vitamin D-Mushrooms on the EU market under the simplified notification procedure.
