Proven Benefits

01Replenishes gut flora after antibiotic use
02Reduces symptoms of IBS (Irritable Bowel Syndrome)
03Enhances immune system function (70% of immunity is in the gut)
04Supports mental health via the gut-brain axis
05Improves nutrient absorption

Chemical Forms

Recommended
  • Lactobacillus and Bifidobacterium strains
  • Saccharomyces boulardii (Yeast probiotic)
  • Spore-based probiotics
Avoid
  • Products without specific strain codes (e.g., just saying 'Lactobacillus acidophilus' instead of 'L. acidophilus NCFM')
Expert Note

Probiotic benefits are highly strain-specific. A brand must list the specific strain identifier (letters/numbers after the name) to prove it matches clinical trials.
