In this pilot study, Lactobacillus supplements in Seattle, Washington were analyzed as to safety and reliability. The contents of twenty brands of Lactobacillus supplement were cultured for viability. Microorganisms isolated from the samples were identified as to genus and species using DNA analysis. Results were compared to contents stated on the bottles. One of the brands tested had organisms isolated that were identical to those stated on the bottle. 30% of the samples had contaminants and 20% of the brands had no growth. Viability of the samples was significantly (p=.014) associated with refrigeration status. From this pilot study it appears that Lactobacillus dietary supplements examined in the Seattle, Washington are not reliable and may not be safe for the consumer.
