The Power of L reuteri for Skin and Gut Health with Dr William Davis
In this episode, Dr. William Davis delves into the fascinating world of L. Reuteri and its impact on skin health, gut and overall well-being. Learn about the potential benefits of this probiotic strain and its connection to gut health.
Topics Covered :
L. Reuteri and its Benefits: Loss in Modern Populations: Dr. William Davis highlights that Lactobacillus reuteri is largely absent in modern people due to antibiotic overuse, unlike in indigenous populations and wild mammals [ 01:16 ]. Initial Benefits: Restoration of L. reuteri can lead to youthful musculature, increased oxytocin (enhancing love and affection), improved libido, and better social behavior [ 02:07 ]. Skin Health: L. reuteri dramatically increases dermal collagen, reducing wrinkles [ 02:31 ]. A clinical trial with 25 women showed a 15% increase in dermal layer thickness using L. reuteri with marine collagen peptides, hyaluronic acid, and astaxanthin [ 03:33 ]. Participants experienced more moisture and reduced wrinkle depth [ 05:19 ]. Body Composition: The same trial unexpectedly showed significant waist circumference reduction, suggesting a targeting of abdominal fat and restoration of youthful muscle [ 05:31 ]. Comparison to GLP-1 Agonists: Dr. Davis contrasts the benefits of L. reuteri with the drawbacks of drugs like Wegovy, which can lead to muscle loss and worsened health upon cessation [ 06:30 ]. Strain Specifics: Dr. Davis mentions using a specific strain, L. reuteri LRDR, in his clinical trials, chosen for its effects in animals and humans [ 09:52 ]. Dosage: Emerging evidence suggests that dosage matters, with higher doses potentially yielding better results [ 11:33 ]. Mechanisms of Action: Endotoxemia Reduction: L. reuteri helps reduce endotoxemia (bacterial breakdown products in the bloodstream), which is linked to various health issues like increased blood glucose, abdominal fat, and inflammation [ 13:39 ]. Oxytocin and Cortisol: L. reuteri increases oxytocin, suppressing appetite, and reduces cortisol levels, which are linked to abdominal fat accumulation [ 16:54 ]. Other Beneficial Bacteria and Practices: Bacillus subtilis: Dr. Davis discusses using Bacillus subtilis to make sparkling juices, utilizing the DE111 strain for CO2 production [ 19:01 ]. Saccharomyces boulardii: Recommended for minimizing gastrointestinal microbiome disruption when taking antibiotics [ 20:51 ]. Lactobacillus crispatus: Crucial for female reproductive health, reducing miscarriage risk, premature deliv
