A study published in 2019 showed that after 132 infants aged 3.5–6 months were randomly treated with formula milk powder containing mixed probiotics or placebo for 4 weeks, the fecal sIgA level in the probiotic group was higher, and the saliva sIgA also showed an increasing trend [ 37 ], suggesting that the intervention effect of mixed probiotics is also more obvious for fecal sIgA.
