The Hidden Link Between Your Microbiome and Mitochondria with Dr. Jason Hawrelak
Aug 2, 2025
Dr. Jason Hawrelak, a top microbiome researcher with over 1,200 citations, dives into the intriguing relationship between gut bacteria and mitochondrial health. He discusses how imbalances in gut bacteria can harm energy production and why probiotics often fail to colonize effectively. Dr. Hawrelak emphasizes that prebiotics may be more beneficial than probiotics for microbiome transformation. He also uncovers myths about probiotics and highlights the importance of diet and specific bacterial strains in achieving optimal gut health.

Episode notes
Gut Health Links to Energy
- Gut health impacts energy via transit time, microbiome composition, and gut integrity.
- Endotoxins from gram-negative bacteria damage mitochondria and promote inflammation, reducing energy.
Probiotics Rarely Colonize Long-Term
- Most probiotics do not permanently colonize the gut, they are transient visitors.
- This means taking probiotics cannot permanently replace lost microbes in your microbiome.
Microbiome Uniqueness and Plasticity
- The microbiome is unique, inherited, and semi-stable but can be influenced by diet, lifestyle, and antibiotics.
- Antibiotics can cause permanent species loss; diversity can be temporarily boosted by nature exposure and diet.
