About Mush-D

Mush-D was establsihed in 2016

The brand Mush-D® was established in 2016, when the founders decided to put words into action. With accumulated over 50 years experience in the fungi business and done many researches, they wanted to use their knowledge about the natural health benefits of mushrooms and create products, which contribute to health, vitality and mood only using mushroom ingredients.

We have the goal make our customers healthier as convenient as possible. When developing our first products, we focussed on 3 main aspects:

  • Natural
  • Convenient
  • Indulging

We use the natural power of mushrooms to create snacks & supplements that are easy to implement into any lifestyle and as tasty as they could be.

What is the vitamin food company?

The vitamin food company basically is the official name of our company. That's why it is written on the back of each of our products.

In the future we plan to use even more vital nutrients from mushrooms than vitamin D in our assortment.
