Some commercial probiotics have been successfully used to produce ''Lactobacillus'' cultures (many brands have also failed at providing usable bacteria according to some homebrewers <ref>[http://www.reddit.com/r/Homebrewing/comments/32tny4/probiotic_lacto_for_souring/cqej952 Conversation on Reddit.

Probiotics that are classified as "dietary suppliments", as opposed to "drugs", may not be as free of contaminates as pure cultures from brewing industry yeast labs <ref>[http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3294522/ Regulatory Oversight and Safety of Probiotic Use.

Dried forms of ''Lactobacillus'' should be stored refrigerated because viability has been seen to decrease as much as 80x when stored at room temperatures <ref>[https://www.facebook.com/groups/MilkTheFunk/permalink/1067614393266774/ Conversation with Bryan of Sui Generis Blog on Milk The Funk. 05/04/2015.]</ref>. Use only fresh products whenever possible (viability of ''Lactobacillus'' drops quickly over time in general), and avoid products that have been stored at room temperature(pill and liquid format), and don't bother using expired products <ref>[http://goodbelly.com/faq/ GoodBelly FAQ.
