Chr. Hansen Lactobacillus acidophilus, LA-5® research shows promise
The bacterial strain Lactobacillus acidophilus, LA-5® comes from our collection of dairy cultures at Chr. Hansen. It is safe for human consumption; it has been granted QPS (Qualified Presumption of Safety) status from EFSA in Europe.1 It has been used in food and dietary supplements since 1979.
The LA-5® strain is a well-researched probiotic that has been described in more than 150 scientific publications. More than 60 of these publications were from human clinical trials that had been run across numerous areas of health. These research studies primarily investigated the LA-5® strain in combination with the Bifidobacterium, BB-12® strain. The studies mainly focused on the effect of these probiotic strains in adults and the elderly.
Support a healthy digestive system
The LA-5® strain, in combination with the Chr. Hansen Bifidobacterium, BB-12® strain, may have beneficial effects on the digestive system. Specifically, studies of these two strains combined in one product have been associated with:
- Improvement in irregular bowel movements2, 3
- Reducing the duration of occasional diarrhea caused by use of antibiotics4, 5, 6, 7
- Balancing the variety of bacteria in the digestive system after using antibiotics7, 8
- Reducing the incidence and severity of occational diarrhea caused by radiation9
