Not all probiotics are created equal—and it’s the strain that makes the difference. You might see names like Lactobacillus rhamnosus or Bifidobacterium longum on a label and assume you’re covered. But unless you know the exact strain—like L. rhamnosus GG or B. longum 1714—you might be missing out on the real benefits. Why? Because different strains from the same species can produce dramatically different effects in your body.

Dr. Shawn explains why choosing the right strain designation is more important than whether a probiotic is refrigerated or shelf-stable. He illustrates this with real-world examples showing how one strain might support stress resilience, while another targets gut motility or immune balance.
