Baby bacteria lowers histamine levels
I’ve been exploring the catch-22 of probiotic supplementation for some time now. The dilemma? Probiotics are necessary for proper intestinal function – the histamine lowering enzymes diamine oxidase and monoamine oxidase live there, so fixing up our poop tube seems like a good idea right?
Not so simple.
Probiotic supplements are fermented (a no go for histamine intolerance/histamine related disorders) and some strains actually raise histamine and tyramine in the body. The good news is that strains commonly found in babies can actually lower histamine, helping us fight allergies and lower our overall histamine burden.
Lactobacillus casei (TISTR 389) andLactobacillus delbrueckii subsp. bulgaricus (TISTR 895) were found to produce BA (biogenic amines). The highest levels of histamine (1820.9 ± 3.5 mg L−1) and tyramine (5486.99 ± 47.6 mg L−1) formation were observed for the TISTR 389 strain, while TISTR 895 produced only histamine (459.1 ± 0.63 mg L−1) in the decarboxylase broth. Biogenic amine potential was not observed for the Lactobacillus acidophilus,Lactobacillus lactis subsp. lactis, Lactococcus lactis subsp. lactis, and Lactobacillus plantarum strains studied. This study confirmed that BA formation is strain dependent and not related to the species. Read the full study here.

The BAD
Lactobacillus casei was shown to produce histamine and tyramine, while Lactobacillus Bulgaricus increased histamine alone.
