Oral health

Based on a scientific and microbiological evaluation, LGG® has been associated with more healthy teeth,14 and with lower levels of specific bacteria that contribute to poor oral health.15

In adults, some of the most researched health areas with the LGG® are:

 
Travel-related loose stools

LGG® has been associated with a reduction in the incidence of loose stools that travelers commonly experience when traveling in countries, regions and areas which present more chance of being exposed to unfamiliar bacteria.9

 
Immune health
