=== Probiotic Options for Infantile Colic (Newborn Stage) ===

==== Evidence-Supported Probiotic Products for Newborn Colic ====

===== 1. BioGaia Protectis Baby Drops (BioGaia AB / also marketed as Gerber Soothe): L. reuteri DSM 17938 =====

Strain & Product: Contains Limosilactobacillus reuteri DSM 17938 (formerly Lactobacillus reuteri), a human breastmilk-derived probiotic. BioGaia AB manufactures it as “Protectis” drops; in some markets it’s sold by Nestlé/Gerber as “Soothe” Colic Drops.
Clinical Evidence: L. reuteri DSM 17938 is the most studied probiotic for colic. An individual-participant meta-analysis of 4 trials (345 infants) found this strain significantly increased colic “treatment success” (≥50% reduction in crying time) compared to placebopubmed.ncbi.nlm.nih.gov<ref>{{cite web|title=pubmed.ncbi.nlm.nih.gov|url=https://pubmed.ncbi.nlm.nih.gov/29279326/#:~:text=Results%3A%20%20Four%20double,fed%20infants|publisher=pubmed.ncbi.nlm.nih.gov|access-date=2026-01-23}}</ref>.

Age Range: Designed for infants 0–12 months. Culturelle labels it for babies “up to 1 year,” and it is safe even for young newborns. Parents are advised to start these drops in early infancy when colic or digestive upset arises. (As always, a pediatrician should confirm severe crying is due to colic and not another issue before starting probiotics.)

Delivery Form: Oil drop format (similar use as other infant drops). Dose is 5 drops daily (providing 10^9 CFU total) administered via dropper by mouth or mixed into cool liquid.

Notes: All the above products are probiotic drops designed for infants, making administration easy (no pills or large volumes). It’s important to use them daily for at least 2–3 weeks to assess benefit, as studies typically observed gradual improvement over that periodpubmed.ncbi.nlm.nih.gov<ref>{{cite web|title=pubmed.ncbi.nlm.nih.gov|url=https://pubmed.ncbi.nlm.nih.gov/29279326/#:~:text=Results%3A%20%20Four%20double,fed%20infants|publisher=pubmed.ncbi.nlm.nih.gov|access-date=2026-01-23}}</ref>link.springer.com<ref>{{cite web|title=link.springer.com|url=https://link.springer.com/article/10.1007/s00431-024-05860-5#:~:text=Conclusion%3A%20The%20synbiotic%20tested%20was,natural%20evolution%20of%20infant%20colic|publisher=link.springer.com|access-date=2026-01-23}}</ref>. If one strain/product is not effective after 2–3 weeks, consult a pediatrician – sometimes an alternative strain (or addressing feeding techniques and other causes) may be needed. Always ensure the baby is otherwise healthy (no red-flag symptoms beyond colic) before attributing crying solely to colic and starting probiotic supplementation.

==== Conclusion ====

For newborns with true colic, probiotics offer a promising, evidence-based intervention to reduce crying and fussiness. The strongest evidence supports ''Lactobacillus reuteri'' DSM 17938, found in BioGaia/Gerber Soothe drops, which consistently shortens crying duration in breastfed infantspubmed.ncbi.nlm.nih.gov<ref>{{cite web|title=pubmed.ncbi.nlm.nih.gov|url=https://pubmed.ncbi.nlm.nih.gov/29279326/#:~:text=Conclusions%3A%20%20L%20reuteri%20DSM17938,with%20colic%20needs%20further%20research|publisher=pubmed.ncbi.nlm.nih.gov|access-date=2026-01-23}}</ref>.

All these products come in infant-friendly drop form, and are suitable from the newborn stage, allowing parents to administer probiotics safely to young babies.

When choosing a probiotic for a colicky newborn, caregivers and healthcare providers should consider the specific strain(s) and supporting evidence: probiotic effects are strain-specific, so a product containing a clinically proven strain (or mix) at the right dose is cruciallink.springer.com<ref>{{cite web|title=link.springer.com|url=https://link.springer.com/article/10.1007/s00431-024-05806-x#:~:text=Probiotics%20are%20%E2%80%9Clive%20microorganisms%20that%2C,trials%2C%20particularly%20in%20breastfed%20babies|publisher=link.springer.com|access-date=2026-01-23}}</ref>link.springer.com<ref>{{cite web|title=link.springer.com|url=https://link.springer.com/article/10.1007/s00431-024-05806-x#:~:text=especially%20in%20breastfed%20babies%20,Bifidobacterium%20longum%20KABP042%20and%20Pediococcus|publisher=link.springer.com|access-date=2026-01-23}}</ref>.

They can be used alongside other colic management strategies (comforting techniques, dietary adjustments if applicable). Always consult a pediatrician before starting probiotics in a newborn, especially if the infant is premature or has underlying health issues. But for otherwise healthy, full-term babies, these evidence-backed probiotic drops represent a gentle and potentially effective approach to ease the distress of infantile colic – giving much-needed relief to both babies and their families.
