1. Check the strain number - no number=unprofessional
Why is it important:
There are different strains of the same strain (such as "Lactobacillus"), and only specific strains (such as Lactobacillus rhamnosus GG) have been clinically validated to be effective.
How to identify:
The qualified label will indicate the strain and strain number (such as "Animal Bifidobacterium Bb-12"), and fuzzy labeling such as "Lactobacillus" is not recommended.
Avoiding pitfalls: Beware of vague propaganda such as "patented strains" and require specific research literature on strains.
2. Check the number of live bacteria (CFU) - higher is not necessarily better
Standard range:
The recommended daily dosage is 5 billion to 40 billion CFU (adjusted according to demand, such as high dosage after antibiotics).
Key points:
Label "number of live bacteria within shelf life" instead of "quantity during production" (transportation and storage may cause loss).
Independent packaging (such as aluminum foil packaging) can better ensure activity than large bottles.
Avoiding pitfalls: Exceeding 100 billion CFU may cause bloating without any additional benefits.
3. Look at the dosage form - prioritize choosing acid and bile salt resistant ones
Recommended dosage form:
Enteric coated capsules (avoiding stomach acid)>powder (requiring refrigeration)>regular tablets/chewable tablets (activity easily lost).
Special Technology:
Strains labeled as "microencapsulation technology" and "stomach acid resistant" (such as Saccharomyces boulardii) have a higher survival rate.
Avoiding pitfalls: Most probiotics in yogurt/beverages cannot reach the intestines (killed by stomach acid).
4. Looking at the formula - single strain or compound strain?
Targeted selection:
Diarrhea: Lactobacillus rhamnosus GG strain+Saccharomyces boulardii.
Constipation: Bifidobacterium longum BB536+Bifidobacterium lactis HN019.
Immunity: Lactobacillus acidophilus LA-5+Bifidobacterium BB-12.
Bonus points:
Containing prebiotics such as oligofructose and inulin can enhance bacterial colonization.
Shelter: Avoid children's probiotics containing ineffective additives such as sugar and essence.
5. Check the storage conditions - the key to activity assurance
Refrigeration required:
Most lactobacilli and bifidobacteria products need to be stored at 2-8 ℃ (cold chain transportation is required for online shopping).
Room temperature resistance:
Spore type probiotics (such as Bacillus coagulans) and Saccharomyces boulardii can be stored at room temperature.
Avoiding pitfalls: Products that claim to be "stored at room temperature" but do not specify the strain type may have become inactive.
Additional note: Applicable population and contraindications
Children: Select strains labeled as "usable for infants and young children" (such as Bifidobacterium brevis M-16V).
Immunodeficient individuals: Avoid yeast (such as Saccharomyces boulardii) and seek medical guidance.
Allergens: Check for allergens such as dairy products and gluten.
