"Most researched probiotic for infant colic"
L. reuteri DSM 17938 has 10+ RCTs for infant colic. A 2018 systematic review confirmed reduced crying in breastfed infants.
PubMed: Sung et al., Pediatrics 2014; Schreck Bird et al., Nutrients 2017 systematic review -
"Contains probiotics naturally found in breast milk"
True. L. reuteri DSM 17938 was originally isolated from human breast milk by BioGaia researchers.
PubMed: Casas & Dobrogosz, Microbial Ecology in Health and Disease 2000 -
"Price value vs. alternatives"
At $0.83/day, BioGaia is competitively priced vs. Gerber Soothe (~$0.75-0.90/day) using the same licensed strain.

"Helps ease colic in all babies"
Benefits are proven for breastfed infants. Formula-fed infant trials show inconsistent results — the page omits this distinction.
PubMed: Sung et al., BMJ 2014 (formula-fed RCT showing no benefit)
Consumer advice
If your baby has colic, this is one of the few probiotic products with genuine clinical evidence behind the specific strain. Look for it at Walmart or Target where it may be slightly cheaper than direct. Note that the evidence is strongest for breastfed infants — if your baby is formula-fed, results may be more variable. Colic typically resolves by 3-4 months regardless of treatment, so don't feel pressured to continue indefinitely. The subscribe-and-save option (15% off) is a reasonable deal if you plan to use it for several weeks. Always consult your pediatrician before starting any supplement for a newborn.
