Probiotics
Also known as Lactobacillus, Bifidobacterium
Probiotics are live microorganisms that, in adequate amounts, can support the gut microbiome. Effects are strain-specific (the right strain matters more than the total count), with the best evidence for digestive issues and antibiotic-associated diarrhea.
Benefits
Eases digestive issues
ModerateCertain strains help with IBS symptoms and antibiotic-associated diarrhea.
Supports immune balance
PreliminaryThe gut hosts much of the immune system; probiotics may modulate it.
Pros & cons
Pros
- Helpful after antibiotics
- Generally very safe
- Targeted strains for specific issues
Cons
- Strain-specific: generic products may not work
- Quality and viability vary widely
Side effects
Temporary bloating or gas
Common in the first days as the gut adjusts.
How to take it
Typical dose
1–10 billion CFU per day of a researched strain
Timing
Consistency matters; many take with or just before food
Common forms
Tip: Match the specific strain to your goal rather than chasing the highest CFU count.
