The REAL Longevity Stack Revealed! - Siim Land on Human Immortality, Gene Editing, Biomarkers

Oct 23, 2025

Siim Land, a longevity educator and biohacker with an anthropology background, shares practical strategies for enhancing lifespan and health. He emphasizes the importance of understanding your biomarkers before diving into supplements or drugs. Discussing diet, he argues for flexibility over strict rules, highlighting the impact of sleep, movement, and environment. Siim also tackles the ethics of gene editing and societal implications while advocating for a balanced approach to physical and mental health as key longevity factors.

INSIGHT

Adaptation Is Humanity’s Core Advantage

Humans succeed because of adaptation and niche construction across environments.
Our evolving environment changes physiological requirements and health priorities.

INSIGHT

Diet Through The Biomarker Lens

Diets vary widely across cultures and individuals so no one-size-fits-all exists.
Food effects depend on individual biomarkers and sensitivities rather than strict dogma.

ADVICE

Assess Biomarkers Before Acting

Measure your health first by checking blood markers and other objective biomarkers.
Use those results to prioritise interventions instead of guessing what to change.

What if the real path to longevity is mastering fundamentals while measuring what matters?

In this episode, recorded at Copenhagen Health Week, Siim Land - author, longevity educator, and anthropology graduate - breaks down a pragmatic roadmap to living longer and better. We get honest about diet debates, biomarkers, and what to do before you touch a single peptide or pharmaceutical.

We cover why adaptation defines human health, how to use blood work and objective markers to see risk decades ahead, the case for sleep, movement, diet, and environment, and where rapamycin, metformin, and methylene blue actually fit. Siim shares his supplement stack, the VO2 max trade-offs with creatine, and a grounded outlook on gene editing, embryo selection, and the ethics of enhancement.

📌 What You Will Learn

• Siim’s stack and why he keeps it simple
• VO2 max, creatine, and training trade-offs
• Social connection and purpose as longevity inputs
• Gene editing timelines and ethical questions
• A clear framework for risk in the “escape velocity” era
