"Helps ease colic, spit-ups, and occasional constipation & diarrhea"
Spit-up and constipation/diarrhea claims lean on weaker evidence than the colic claim, which has the strongest trial support.
-
"Effects in formula-fed infants"
Trials show DSM 17938 works best in breastfed infants; formula-fed infant results are more inconsistent across studies.

Consumer advice
This is one of the more evidence-backed infant supplements on the market — the specific strain (DSM 17938) has real randomized trial data behind it for colic, unlike most probiotics that lean on generic "probiotic" science. Still, talk to your pediatrician before starting, especially for formula-fed babies where trial results have been less consistent. Don't expect it to fix every digestive issue — the colic evidence is the strongest part of the claim list, the rest (spit-up, occasional constipation/diarrhea) is more anecdotal. Compare unit price against store-brand DSM 17938 drops before assuming this is the only or best option.
Claims vs Evidence
MODEST2 of 4 claims supported by evidence. These grades score the marketing, not the product — a claim only counts as supported when the label discloses a dose that matches the studies behind it, so blends that hide doses cap at “partial” no matter how good the formula is.
"Helps ease colic, spit-ups, and occasional constipation & diarrhea"

Colic evidence is solid; spit-up/constipation/diarrhea claims are weaker, less studied.
