The objective of this study was to examine the effect of daily probiotic supplementation upon the immune profile of healthy participants by the assessment of ex vivo cytokine production. Twenty healthy adult volunteers received a multi-strain probiotic supplement consisting of two strains of Lactobacillus acidophilus (CUL60 and CUL21), Bifidobacterium lactis (CUL34) and Bifidobacterium bifidum (CUL20) and fructooligosaccharide for 12 weeks. Blood samples were collected at baseline, 6 and 12 weeks. Peripheral blood mononuclear cells (PBMCs) were isolated and cultured ex vivo in the presence or absence of lipopolysaccharide and cytokine production was assessed. Postintervention, a significant decrease in the production of interleukin-6 and interleukin-1β was apparent when PBMCs were incubated in the presence of lipopolysaccharide, whilst a significant increase in IL-10 and transforning growth factor-β production was seen when the cells were incubated without an additional stimulus. This preliminary study demonstrates the potential of a multi-strain probiotic supplement to alter the immune response as demonstrated by changes in ex vivo cytokine production. Such results demonstrate the potential benefit of probiotic supplementation for healthy individuals and warrants further investigation.
