Joe Rogan Experience #2529 - Zach Bush
"Bayer started to to investigate the impact of interconnected relationships on human biology and fertility in the 1940s. we call it World War II and concentration camps."
Zach Bush alleges Bayer’s early fertility and microbiome research was linked to Second World War-era concentration camp studies. In a conversation with Joe Rogan, he also claims Bayer was bought by a German firm in the 1930s and later re-emerged after the war, while saying other organisations did similar work.

About this episode

Joe Rogan talks with physician and wellness entrepreneur Zach Bush about diet, technology, chronic disease and what Bush frames as a broader biological “reconnection” for humanity. Bush argues that modern life has become “abstract” and detached from nature, and he repeatedly claims that restoring microbial and ecological relationships is central to human health. A major strand of the episode focuses on herbicides and industrial agriculture: Bush says glyphosate acts as an “antibiotic” that disrupts mitochondrial energy production and links it to rising obesity, diabetes, allergies, autoimmune disease, neurological disorders, cancer and fertility decline. He also extends this argument to foetal development, claiming “gender dysregulation” is a downstream effect of reduced metabolic capacity.

The conversation moves into contested historical and geopolitical assertions. Bush alleges Bayer’s early fertility and microbiome research was tied to Second World War-era concentration camps and claims a Lancet paper estimated around 35 million deaths connected to US economic sanctions over 40 years. He also recounts time with Amazonian indigenous communities and describes consumer products—such as boxed sweetened juice—as disrupting traditional self-sufficiency.

Rogan and Bush explore speculative themes including ancient pyramid-building, telepathy, and Bush’s claim that geometric “biogeometry” shapes can affect biology. Bush says Switzerland hired an Egyptian figure, Ibrahim Karim, to “recode” 5G networks using such shapes. Later, Bush describes clinic experiences where he says autistic children improved after treating parents’ “emotional field,” presenting autism as a heightened sensory and relational state rather than a disorder.

Throughout, Rogan challenges parts of Bush’s worldview while largely allowing long, free-ranging explanations; many scientific and historical claims are presented without supporting documentation in the transcript.
