What to Take With & Avoid

Take With

  • Prebiotics (fiber) - feeds the probiotics
  • Digestive enzymes - supports overall gut function
  • Glutamine - supports gut lining

Avoid / Separate From

  • Antibiotics - take 2-3 hours apart to prevent killing probiotics
  • Very hot foods/drinks - can kill bacteria
  • Alcohol (heavy) - disrupts gut microbiome

Common Mistakes to Avoid

  • Taking with hot coffee - kills the bacteria

  • Expecting immediate results - microbiome changes take weeks
  • Not considering strain specificity - not all probiotics do the same thing

Pro Tips

  • Refrigeration often required - check label
  • Different strains do different things - match to your needs
  • Start low and increase slowly to avoid bloating
  • Prebiotics enhance probiotic effectiveness
