Colonisation Efficacy of Oral Probiotic Fast Melt Powder

Assessment of Colonisation of Probiotic Bacterium Streptococcus Salivarius From a Fast Melt Powder Format to the Oral Cavity

To evaluate the colonisation efficacy (i.e. ability of the probiotic bacteria to remain in your mouth) of a fast melt powder that quickly dissolves in the mouth. The fast melt powder will contain a Streptococcus salivarius probiotic and the study is to be done in healthy adults.

This is a double-blind, randomized controlled study with no cross over to evaluate the colonization efficacy of fast melt powders containing a commercially available probiotic bacterium Streptococcus salivarius K12.

Participants will be randomly assigned to one of the 2 groups consuming Fast Melt powder containing two different doses of Streptococcus salivarius K12 over a seven day period. Saliva samples will be collected at predetermined time points pre and post intervention. Colonization efficacy will be determined by enumerating the probiotic in the saliva samples using standard microbiological techniques.
