Brief summary
The main hypothesis of this study is that there will be a significant increase of Lactobacillus rhamnosus GG (LGG) and Bifidobacterium lactis (BB-12) in the stool of healthy humans following daily consumption of a probiotic supplement containing these specific strains of probiotic bacteria.
Detailed description
To demonstrate recovery of live probiotic bacteria in the stool.
Interventions
Dosage is 1 individually wrapped packet (1 gram) containing probiotic powder per day for 21 days
