About us

Microdosing Institute is a global education, research, and community platform. We build vital connections in society and merge ancient wisdom with modern science to ensure the safe, conscious, and effective microdosing of psychedelics.

In recent years, there has been an increase in awareness and acceptance of microdosing psychedelics. At renowned universities and knowledge institutions, more research is being conducted into the therapeutic effects and applications of psychedelics. Patients worldwide are signing up for psychedelic therapies and ceremonies to overcome their trauma, release anxiety, and relieve depression. Each day, more people benefit from the healing and therapeutic effects of microdosing.

We’re still far from overcoming the—in our opinion unjust —stigma on psychedelics and conscious use. However, with a renewed transmission of ancient wisdom, the global narrative of these substances is gradually transforming: from (harmful) drugs to transformative therapeutic tools that can significantly benefit humanity.  

Microdosing Institute has taken an active role in that shift. We advocate for safe and responsible microdosing to those interested in mindfully exploring this transformative tool. Only then can it be effectively used to gain different perspectives on our health, lifestyles, and relationships.

Our mission

Our mission is to advocate for mindful microdosing by offering education, community support, 1:1 guidance, and facilitating scientific research. In addition, through open conversations about (microdosing) psychedelics, we want to eliminate the surrounding stigma. This way, each insight, experience, and connection can become a building block in creating a healthy, balanced, and thriving society. 

Our story

We are Hein Pijnnaken and Jakobien van der Weijden, the founders of Microdosing Institute. Our curiosity about microdosing was sparked by Dr. James Fadiman and his collection of anecdotal reports filled with positive experiences of these “sub-perceptual” doses of psychedelics. We were astounded by the findings and quickly realized that microdosing is much more than just a “hack” for more focus and creativity. Personal experimentation has helped us gain insights into the wellbeing, healing and therapeutic benefits of microdosing, and we have also begun independent investigations into the effects of microdosing on ADHD/ADD, cluster headaches, and depression. 

Over the course of these explorations, we have been fortunate to work closely with Dr. James Fadiman as an advisor and friend. Eventually in 2017, we started a Dutch information and community platform named Microdosing.nl. Since late 2020, our platform is operating internationally as Microdosing Institute. Alongside James Fadiman, we are the initiators of the International Microdosing Coaching Association


Hein is a Transformational Coach, NLP Master (advanced), and microdosing educator. While growing up in the Netherlands—one of the most psychedelic-friendly countries in the world—he became familiar with psychedelics in his early college years and has used them as transformative tools ever since. Today, he has over 30 years of experience guiding psychedelic sessions and has immersed himself—both theoretically and practically —in the topic of microdosing since 2016. He strongly believes microdosing is an incredible tool for self-development, especially in combination with effective coaching. 


Jakobien is a psychedelic guide, Holistic Coach, and microdosing educator. She has been in service of the psychedelic renaissance since 2003, thoroughly studying entheogenic plants and actively promoting psychedelic research. During her travels in Latin America in 2008, she started attending plant medicine ceremonies from different traditions and cultures and has used this experience to deepen her understanding of psychedelics and the human psyche. From there, it was a small step into the world of microdosing. 

Due to her work at a Dutch smart shop and subsequently organizations such as OPEN Foundation, Psychedelic Society of the Netherlands, and Synthesis Institute, she has built close relations with scientists, therapists, and knowledgeable facilitators across the planet. 

We have gone into the depths of microdosing and started using our experience and knowledge to provide personalized microdosing coaching. We want to empower people to optimize their lives and wellbeing.  

Our partners

Connection, collaboration, and synergy have always been essential values of Microdosing Institute. As a result, we have built an extensive network with people, organizations, and universities in the psychedelic field. Together, we’re on a quest to uncover answers to burning questions about microdosing. 

Just like a mycelium network, these connections guarantee an indispensable and reliable ecosystem with a shared goal; lower the barriers to safely access the healing, therapeutic, and transformative benefits of psychedelic substances. Who are the partners of Microdosing Institute?
