Consumer advice
- • Check the CFU count per capsule—if it's not listed on the product page, contact the seller. Clinical trials used 6.5-20 billion CFU/day; lower doses may not be effective.
- • Compare to generic L. reuteri DSM 17938 products from other brands (Culturelle, Nature's Way, iFlora)—you'll likely find the same strains at 50-70% lower cost.
- • If you have IBS, note that L. reuteri works better for some subtypes (diarrhea-predominant) than others; consider consulting a gastroenterologist about whether this specific strain matches your symptoms.
- • Probiotics require proper storage (refrigeration or shelf-stable formulation)—check if this product needs refrigeration and whether the seller ships with temperature control.
