Antibiotic Recovery

Antibiotics are a nuclear bomb to the microbiome. Here is how the clinical data says to recover.

Preventing Antibiotic-Associated Diarrhea (AAD)

You should not wait until after antibiotics to start probiotics. Co-administration is key, but timing matters. Take the probiotic at least 2-4 hours away from the antibiotic dose.

The Big Two

The World Gastroenterology Organisation (WGO) strongly recommends only two primary interventions for preventing AAD and C. difficile infections:

  1. Saccharomyces boulardii (CNCM I-745): Because it is a yeast, it is completely immune to antibacterial antibiotics. You can take it at the exact same time as your antibiotic. (Typical dose: 250-500mg/day).
  2. Lactobacillus rhamnosus GG: Extensive data showing prevention of AAD, particularly in pediatric populations.

Post-Antibiotic Rebuilding

Recent studies (e.g., Suez et al., 2018 in Cell) have shown that standard multi-strain probiotics might actually delay the return of your native microbiome post-antibiotics. The transient probiotic strains take up space, preventing your original flora from regrowing.

The better strategy post-antibiotics? Focus on prebiotics and a highly diverse diet of fermented foods and fiber to feed whatever native strains survived, rather than bombing the gut with a generic 50-billion CFU supplement.
