Probiotic labels can be confusing, with big CFU numbers and long strain names that don't mean much on their own. Here's what actually matters when comparing options.

What to Actually Look For

  • A
    Strain diversity

    Multiple strains tend to offer broader support than a single-strain formula.

  • B
    CFU count

    A higher number isn't automatically better. Consistency matters more than chasing the biggest number.

  • C
    Shelf stability

    A probiotic that doesn't need refrigeration is easier to take consistently, which matters more than lab specs.

“The best probiotic is the one you'll actually take every day.”

Common Mistakes to Avoid

Switching probiotics frequently, expecting overnight results, or choosing based on CFU count alone are common ways people end up disappointed. Give a formula a few weeks of consistent use before deciding whether it's working.
