This study reconfirms an earlier clinical study of 23 subjects by Dr. J. Burton and co-workers, (published in the Journal of Applied Microbiology, v100 (2006) 754–764) where Streptococcus salivarius K12 was shown to be effective at reducing the levels of volatile sulfur compounds (VSC) in the exhaled breath, which are responsible for chronic oral malodor and halitosis.
