Probiotic Supplements
With so many probiotic supplements on the market, it can be overwhelming to figure out which one is right for you. Not all probiotics are created equal, and choosing an effective product goes far beyond just picking the highest CFU count.
This guide is designed to help you understand what actually matters when choosing a probiotic. Whether you're supporting digestive health, immune balance, or women’s health, the goal is to help you choose a probiotic that is safe, evidence-based, and tailored to your needs.
Strain Specificity
Look for clearly labeled strains, not just species.
Example: Instead of just Lactobacillus acidophilus, it should list Lactobacillus acidophilus La-5
Why it matters: Specific strains have been clinically studied for targeted benefits like gut health, immune support, or vaginal balance
Helpful strains by goal:
Digestive health: Lactobacillus acidophilus, Bifidobacterium lactis
Vaginal health: Lactobacillus rhamnosus GR-1, L. reuteri RC-14
Immune support: Bifidobacterium bifidum, Lactobacillus plantarum
CFU Count (Colony Forming Units)
Look for at least 10 billion CFUs per serving for general support
Higher CFUs (30–50 billion+) may benefit people with GI issues or those taking antibiotics
More is not always better. Strain quality and diversity are more important
Strain Diversity
Aim for 5–15 strains to support different areas (gut, immune)
Single-strain probiotics can be helpful in specific cases, but diversity gives broader coverage
Prebiotics and Post-biotics
Prebiotics (like inulin, FOS, or GOS) feed the good bacteria
Post-biotics are beneficial byproducts of fermentation that support gut lining and immune health
Bonus if included! It’s a more complete formula.
Stability & Storage
Shelf-stable? Check if refrigeration is required
If no refrigeration is needed, it should be labeled “Shelf-stable” and protected from heat/humidity
Look for acid-resistant or delayed-release capsules to survive stomach acid
Transparency and Quality Testing
Look for:
Third-party testing
Expiration date and guaranteed CFUs through expiration (not just at manufacture)
Clinical backing
Tailored Formulas (if needed)
Choose based on your needs:
Women’s health: Includes L. reuteri, L. rhamnosus, sometimes cranberry
Kids' probiotics: Lower CFUs and age-appropriate strains
Travel/antibiotic support: Saccharomyces boulardii or high-dose blends
Delivery System / Capsule Design
This is critical for making sure the bacteria survive your stomach acid.
Look for:
Double-capsule delivery
Delayed-release or acid-resistant capsules
Microencapsulation (protective coating on individual strains)
Spore-forming strains (Bacillus coagulans, B. subtilis) — naturally more stable
Avoid basic vegetable capsules with no protection
