eRECYn Project – Sustainable Production of Standardized Dietary Supplements from Hericium

MycoMedica Ltd. represents, in my view, a company that is a leading European producer of dietary supplements derived from fungi with medicinal properties. It is also a company with which I can reliably collaborate and one that has earned my trust.

My collaboration with Andrej Gregori began even before the establishment of MycoMedica Ltd. We first met at the IMMC4 (International Medicinal Mushroom Conference) in Ljubljana in 2007, an important scientific meeting dedicated to research on medicinal fungi. The conference served as a platform for the exchange of knowledge and experiences regarding the medicinal properties of fungi. At the time, he was a student and a member of the organizing committee of the congress.

Through these activities, our paths in scientific research and product development eventually intersected, contributing to the development of a wide range of products now available through MycoMedica Ltd. for both human and animal use.

Over the past twenty years, our communication and collaboration through meetings at congresses across Europe and Asia have only strengthened. As a result, we have also co-authored peer-reviewed scientific publications presenting complex in vitro and in vivo research in well-recognized journals, including Pharmaceuticals.

Finally, MycoMedica has my full trust and support, which they have earned through their strong scientific foundation as well as through personal experience. Both my family and I have been using their products for a considerable period of time.

My collaboration with Assoc. Prof. PhD Andrej Gregori and his company MycoMedica (Goba) has lasted for many years, and I consider it one of those partnerships that begins professionally – and then grows into something that is simultaneously scientifically productive, pedagogically inspiring, and personally highly trustworthy.

Even during my previous position at the Faculty of Pharmacy, University of Ljubljana, I collaborated with Assoc. Prof. PhD Gregori on research projects, including studies on the bioactive compounds of Hericium erinaceus, which resulted in a notable publication in an international journal. Projects like these quickly reveal who can combine scientific rigor with an understanding of real-world practical needs – and this is one of his greatest strengths: broad knowledge, methodological consistency, and the ability to translate complex content into practical solutions.

Our collaboration has not been limited to research. We continue to work together as co-instructors in the doctoral course Natural Medicines from Fungi, Plants, and Animals at the Biotechnical Faculty, where Assoc. Prof. PhD Gregori consistently demonstrates that he is not only an excellent researcher but also an outstanding educator: clear, systematic, evidence-based, and open to discussion. We also collaborate in an intensive phytotherapy course for physicians, where his expertise is particularly valuable due to his responsible approach to evidence, safety, and realistic boundaries of application.

At MycoMedica, I also appreciate their focus on development and the high standards they maintain in their products as well as in communication with professional and general audiences. Working with Assoc. Prof. PhD Gregori is genuinely enjoyable: professional, reliable, fair, and driven by a sincere desire to do things well – not just quickly.

Based on ancient Chinese and Asian experience, medicinal fungi have been a source of the most effective pharmaceutically active compounds for over two thousand years. Fungal polysaccharides, proteins, proteoglycans, terpenoids, sterols, steroids, and other compounds represent an extraordinary treasure of completely naturally produced molecules with highly proven efficacy.

Historically, most of this reputation was associated with wild fungi from nature. However, since the 1960s, the cultivation of medicinal fungi has expanded significantly, contributing to increased production and use of various well-known and highly effective medicinal mushrooms. The recent growing demand for products derived from medicinal fungi, particularly those with anticancer and immunomodulatory effects, has further increased the natural production of medicinal fungi and their products. While in East Asian countries, where the use of medicinal fungi products has been largely validated through clinical experience and is flourishing, the Western world still struggles to fully recognize the benefits of medicinal fungi and their products.

With long-standing experience based on highly productive collaborations with major Chinese institutions and strict Eco-Bio production adhering to the most demanding certification standards, MycoMedica is one of the leading and most respected producers in the EU in this field.

By using entirely natural raw material sources combined with a non-speculative commercialization of their highly effective products, MycoMedica enjoys strong consumer trust.

The discovery of two fungi in the belongings of the frozen Ötzi mummy demonstrates that humans already used fungi for medicinal purposes in prehistoric times – not only in China, but also in Europe. Just as in those times, fungi remain important in medicine today and represent significant potential in healthcare.

Four of the most important drugs are derived from fungi: the antibiotic penicillin; ergotamine, which regulates vascular (capillary) contraction; monacolin K – lovastatin, which lowers cholesterol; and cyclosporin, which suppresses the immune response in organ transplants and in the treatment of autoimmune diseases. In addition to these, many other fungi contain diverse bioactive compounds. Their effects on human well-being are broad, providing therapeutic benefits and alleviating numerous illnesses.

A balanced and varied diet, providing the body with essential nutrients for normal function, is crucial for human health. Nevertheless, modern lifestyles often require additional support for the organism, either for general well-being or for the prevention and treatment of diseases. In this context, medicinal fungi products hold a special place, as they contain numerous bioactive compounds with beneficial effects on the immune system, overall resilience, and general well-being.

Of the drugs mentioned above, I have personally only used penicillin. This is because I regularly use various medicinal fungi products as a dietary support, rather than as a “dietary supplement” in the bureaucratic sense. I understand this use as support for the body’s defense mechanisms, not as a replacement for medical treatment. Both my personal experience and numerous international scientific studies, conducted in collaboration with MycoMedica, demonstrate that medicinal fungi can play an important role in maintaining health, making this a promising and interesting area of modern medicine.

Among the many medicinal fungi, notable species include: Ganoderma lucidum (Reishi), Hericium erinaceus (Lion’s Mane), Grifola frondosa (Maitake), Cordyceps species, and Trametes versicolor (Turkey Tail), from which the polysaccharides PSK (Krestin) and PSP have been isolated, known for their anti-cancer properties and their ability to reduce side effects of radio- and chemotherapy.

MycoMedica produces premium GOBA products from these and other medicinal fungi (“mycelia”), which I have been occasionally using for many years to support my health and well-being.

My collaboration with MycoMedica d.o.o. – like many of the best things in life – began entirely by chance, through a student research project back in 2017. Even then, I found the use of medicinal fungi very interesting, though I could never have imagined just how many opportunities this field would offer.

Throughout my academic career, I have had the opportunity to collaborate with many international partners, including academia, research institutes, and industry. I must admit, however, that working with MycoMedica is one of the closest collaborations I have experienced. The company, led by my good friend Assoc. Prof. PhD Andrej Gregori, is dedicated to the development and production of medicinal fungi products at the highest level, and they invest tremendous effort in the continuous improvement of GOBA products – which I have personally tested and found to be truly effective.

Our joint research and development path is founded on mutual trust, honesty, hard work, and an endless curiosity that drives progress and innovation in the field of dietary supplements. Over the past decade, we have successfully completed numerous applied projects (PKP and PUŠ, with a fifth joint project currently underway), where University of Ljubljana students acquire new skills and laboratory experience, while research results contribute to the development of new technologies and also lead to scientific publications (for example, in the field of heavy metal remediation in water) and professional symposia (17 contributions in total).

In addition, under joint supervision, five bachelor’s and master’s theses have been successfully completed in the field of medicinal fungi research. I am sincerely grateful for the opportunity to collaborate with MycoMedica and believe that our joint efforts will continue to yield many achievements in the future. Thank you very much!
