What the AI looks for in Acidophilus Nutritional Supplements
- Strain designation
- Prefer labels that list the strain code after the species, for example L. acidophilus NCFM, not just the species name. Evidence is strain-specific, and a species name alone tells you little.
- Count guaranteed through expiration
- The CFU count should be guaranteed at expiration, not at the time of manufacture. Live cultures die off during storage.
- Storage
- Follow the refrigeration requirement on the label. Heat exposure kills the cultures in refrigerated products.
- Dairy and allergens
- Check for milk-derived growth media if you are allergic to dairy. Some acidophilus products are cultured on dairy.
Brands that matter
- Florajen: Refrigerated, high-potency acidophilus specialist.
- NOW Foods: Budget shelf-stable option.
- Bio-K+: Fermented drink and capsules containing a strain-designated L. acidophilus.
What to avoid
- Labels that give only a manufacture-time CFU count
- Products with no strain codes
- Leaving refrigerated products in a hot car or mailbox
Questions
Is acidophilus the same as a probiotic?
It is one probiotic species. Many better-studied probiotics use other species or strains.
