Episode #148: Kyal Van Der Leest: Liver Health, Gut Health, and Detoxification

About this video

Formulator Kyal Van Der Leest joins Niddam to connect liver health, gut health, and detoxification. He argues the liver functions as the body’s processing plant, that bile flow is central to clearing hormones and toxins, and that sluggish detox pathways often surface as skin problems when other exit routes are overwhelmed. The conversation covers the endoplasmic reticulum and protein folding as an aging hallmark, how bile acids shape the microbiome and guard against bacterial overgrowth after gallbladder removal, and why skin, hormones, and gut cannot be treated as separate systems. Van Der Leest also shares an n-of-1 anecdote about his own family, which Niddam explicitly flags as anecdote rather than evidence. The episode promotes the guest’s own supplement company.

Key takeaways

• Skin breakouts can be a signal to look upstream at liver, bile flow, and gut health rather than only treating the skin itself
• Bile does double duty: it helps clear hormones and toxins and helps keep gut bacteria in their proper territory
• Protein misfolding is presented as a hallmark of aging that detoxification capacity influences
• A single family’s dramatic anecdote is still an anecdote; Niddam models labeling it as such before anyone generalizes from it
• The guest’s formulations blend oral peptides with botanicals, illustrating the ‘stack’ philosophy of hitting several biochemical targets at once
