In this episode of the Biohacker's Podcast, Teemu Arina speaks with Matt Maruca, founder and CEO of Ra Optics, to examine the critical role light plays in human biology.

Matt reframes light as a primary biological input that regulates circadian rhythm, hormone production, mitochondrial efficiency, and sleep quality. He explains how excessive exposure to artificial blue light (especially after sunset!) disrupts melatonin release and contributes to metabolic dysfunction, poor recovery, and chronic fatigue. Ra Optics was founded to address these challenges through scientifically engineered eyewear that selectively filters harmful wavelengths while preserving beneficial light.

The discussion moves beyond blue light fear-mongering into practical circadian strategy. Matt emphasizes the importance of bright, full-spectrum light exposure during the day to anchor biological timing, while advocating warm, low-intensity lighting in the evening to support sleep. He highlights the role of red and near-infrared light in mitochondrial energy production and recovery, and cautions against low-quality lenses that distort vision or block indiscriminately.

Looking forward, Matt envisions a future where personalized light environments - integrated with sleep and performance data - become central to health optimization. The episode concludes with a shared message: improving light hygiene is one of the highest-leverage, lowest-effort interventions available in modern biohacking.

In this episode of the Biohacker's Podcast, Teemu Arina is joined by Jan K. Górczyński - the founder and CEO of BeKeto, a leading brand in the keto and low-carb market across the UK and EU.

In just five years, Jan expanded BeKeto to offer nearly 200 products across multiple categories, achieving a presence in 30 countries. As a serial entrepreneur, his companies generate over 10 million EUR in revenue. Jan is passionate about the execution in both life and business and is deeply committed to healthy living. He is an enthusiast of low-carb and keto diets, biohacking, and enjoys frequent sauna sessions.

Teemu and Jan dive into the evolution of ketogenic nutrition, metabolic performance, and the data-driven approach behind BeKeto’s product line. Jan explains that the company emerged from a gap in the European market. By focusing on ingredient purity, transparent formulations, and repeated glucometer-based validation, BeKeto positioned itself as a trusted source for individuals pursuing sustained ketosis. The discussion emphasizes how stable energy, mental clarity, and appetite regulation arise when the body shifts from glucose dependency to ketone-driven metabolism.

Teemu and Jan further explore the role of exogenous ketones, ketogenic snacks, and electrolyte formulations in supporting performance, recovery, and cognitive output. They highlight consumer misconceptions - particularly the confusion between “dirty keto” and true metabolic ketosis - and underscore the importance of consistency, clean ingredients, and adaptation support. Looking ahead, Jan predicts a convergence between ketogenic nutrition and continuous metabolic monitoring, enabling individuals to tailor diet and supplementation with precision. The episode concludes with a shared message: ketosis is most powerful when approached as a long-term, sustainable lifestyle rooted in intentional choices and measurable data.

In this episode of the Biohacker's Podcast, Teemu Arina, curator of the Hololife Summit, interviews Christian Drapeau, stem cell researcher and CEO of STEMREGEN.

They dive into the emerging science of adult stem cells as a self-repair mechanism in the body, comparing it to the immune system. Christian explains that when injury or damage occurs, adult stem cells are released from the bone marrow, travel through the bloodstream, and contribute to tissue regeneration throughout the body.

The conversation covers the synergy between stem cell activity and mitochondrial health, particularly focusing on NAD+ and energy metabolism. Christian highlights the difference between natural, daily enhancement of stem cell release through plant-based supplements versus one-time injections—which carry risks such as contamination or genetic instability. The episode also details STEMREGEN’s proprietary blends and ingredients designed to support stem cell release, circulation, and function. Christian discusses clinical results, dietary synergies (like seaweed, omega‑3s, and polyphenols), and a daily protocol aimed at optimizing repair, reducing inflammation, and promoting longevity from within.

Christian and Teemu explore how lifestyle factors, nutrition, and targeted supplementation can naturally enhance stem cell release, migration, and function - without risky or expensive stem cell injections. Christian shares details on STEMREGEN’s formulations, including plant-based ingredients like fucoidan, aloe macroclada, and green tea polyphenols, and outlines a practical daily protocol for activating the body's self-renewing systems.

In this episode of the Biohacker's Podcast, Teemu Arina is joined by Silver Laus to discuss the history of Estonia's resilient people and how the country's beautiful and potent nature helped them along the way.

Silver Laus is one of the leading voices in the functional mushroom space, combining deep knowledge of ancient fungal wisdom with the latest scientific advancements to help people live stronger, healthier, and more vibrant lives.

Estonia's unique position at the crossroads of northern Europe shaped its character through centuries of struggle. According to Laus, this small Baltic nation's history is deeply intertwined with Viking culture, an aspect many outsiders overlook.

This resilience manifested in the nation's relationship with nature. While Christianity swept through Europe, condemning practices like sauna use, Estonians maintained their traditional knowledge and connection to the forest.

As the CEO of Shroomwell, one of the world’s premier mycotechnology companies, Silver Laus has been instrumental in pioneering potent extraction methods, creating high-performance mushroom supplements, and shaping a global wellness brand rooted in wholesome principles.

Shroomwell's approach to mushroom cultivation blends ancient wisdom with cutting-edge techniques. Rather than harvesting exclusively from wild sources, the company has developed sustainable farming methods that mimic natural stressors while increasing yield.

In this episode of the Biohacker's Podcast, Teemu Arina is joined by Siggi Clavien, the founder and CEO of Equilibrium Labs, for an eye-opening discussion on the liver’s critical role in overall health. Clavien, a biotechnology pioneer with a background in plant-based medicine from Cornell University, offers a fresh perspective on the liver, calling it the "master regulator of human health" and the "general of the body." He explains how this vital organ goes far beyond detoxification, playing a central role in immune regulation, hormone management, and nutrient distribution. Drawing on both ancient healing traditions and cutting-edge science, Clavien presents a powerful framework for understanding and optimizing liver function.

Throughout the conversation, Clavien highlights the rising global concern of non-alcoholic fatty liver disease (NAFLD), affecting a staggering 38% of Western populations. He emphasizes the liver's remarkable regenerative capabilities, revealing how the liver can recover even from substantial damage. The episode also delves into practical biohacks for supporting liver health, such as intermittent fasting, photobiomodulation, and the surprising benefits of drinking coffee. Additionally, Clavien discusses the importance of early diagnostics and how traditional blood tests often fail to catch liver issues in time. His holistic approach, which integrates emotional and spiritual wellness, ties the liver’s function to broader concepts of self-love and well-being. Tune in to learn how understanding and supporting the liver could be the key to better health.
