Acidophilus & Bifidus
Natural Factors
Overview
The blend of well-researched probiotic strains (Lactobacillus acidophilus, Bifidobacterium bifidum, Lactobacillus rhamnosus) offers general digestive health benefits and specific support for conditions like antibiotic-associated diarrhea. The total CFU count of 5 billion active cells at expiry is a good maintenance dose, and the inclusion of a 'Proprietary Synergistic Blend' contains some specified strains. However, the exact ratios within the proprietary blend are not fully disclosed, which can make it hard to assess optimal dosing for each individual strain.
The Good
Contains well-researched probiotic strains (L. acidophilus, B. bifidum, L. rhamnosus).
Lactobacillus rhamnosus (LGG) is specifically effective for antibiotic-associated diarrhea and acute gastroenteritis.
Guaranteed potency of 5 billion active cells at expiry.
The Bad
The 'Proprietary Synergistic Blend' prevents full transparency of individual strain concentrations, making precise dosing assessment difficult.
Contains lactose, whey, and goat milk, which may not be suitable for individuals with dairy sensitivities or allergies.
Requires refrigeration for maximum potency, which can be inconvenient.
Is it for you?
Best For: Individuals seeking digestive support, those with gastrointestinal issues, general gut health maintenance
