Good produkt and i will by again
I love this brand
I originally got this from a friend to try and I've been using it for a while now. Since then I sleep better and more deeply, and I wake up less tired. I also take one during stressful periods, and I notice it works quickly.
I've since recommended it to several people. For me this is absolutely the best choice and a product I'm very happy with.
I have also only taken this supplement for just over a week and am starting to notice better sleep. I am gradually waking up less times in the middle of the night for no reason, and feeling more rested in the mornings.
Amazing products - Youc an feel the difference from the first moment! Will be back to get more - definitely make it a daily supplement from now on
It has really made a difference in my sleep. I find myself rest much better.
Excellent product.
Brilliant will order again
My cosrisol levels have dropped significantly. Just awesome.
Game-changer
We Love Shrooms
In 2020, we launched our first mushroom brand: Microdose Pro. It became a hit, featured in Men's Health
, Wired
, Quote
, and a dedicated article on NU.nl
, the biggest news platform in the Netherlands.
In 2023, we took it further and started Human Pro, with one clear focus: functional mushrooms, done right.
We grow our own functional mushrooms in the Netherlands. For adaptogens like ashwagandha, where the herb simply does not grow here, we go to the source instead and pick the most clinically studied extract we can find.
Our mission is to educate, set a new standard, and produce the highest-quality mushroom extracts available, grown on our own farm in the Netherlands.
We picked the one that is actually studied.
“A lot of ashwagandha online is generic, unstandardized, and you never really know what is in it. We chose KSM-66, the most clinically studied extract, root only and standardized to 5% withanolides, and we test every batch before it ships.”

By repurposing agricultural byproducts like sawdust, wood chips, and grain husks as substrates, we reduce waste while creating a nutrient-rich foundation for mushroom growth. These practices are complemented by renewable energy sources, including solar power and contributions from a local wind collective, ensuring a minimal environmental footprint.
These materials are carefully blended with minerals and sometimes yeast obtained from nearby breweries. This localized and sustainable approach ensures that the functional mushrooms we grow have an optimal, nutrient-rich medium tailored to their needs.
This method retains beneficial properties in the substrates while still eliminating harmful microbes. It also reduces energy consumption, enhancing the overall sustainability of our Dutch farming operations.
They improve fertility, attract beneficial organisms, and even serve as a natural deterrent against harmful fungi. While this process applies to the functional mushrooms we grow in the Netherlands, we continue to explore recycling solutions for high-quality plastic waste from substrate bags to further our zero-waste goals.
This setup significantly reduces the carbon footprint of our functional mushroom production. While not all our products are produced in the Netherlands, this farm reflects our commitment to sustainability.
These substrates, enriched with organic matter and fungal compounds, improve soil fertility and reduce the need for chemical fertilizers and pesticides. While this applies specifically to our Dutch operations, it highlights our broader commitment to environmentally conscious practices.
Unlike traditional methods that rely on mass-produced substrates and high-energy sterilization, we create substrates in-house, use energy-efficient pasteurization, and repurpose agricultural byproducts. These practices, exclusive to our Dutch farm, ensure higher-quality mushrooms while actively benefiting the environment.
