Solgar Multi-Billion Dophilus vs BioGaia Protectis Baby: What Does the Data Say?
Advanced Multi-Billion Dophilus from Solgar packs four specific strains including LA-5, BB-12, LGG and L. casei 431 at 5 billion CFU per serving while Protectis Baby from BioGaia delivers just one strain, L. reuteri DSM 17938, in easy drop form with added vitamin D3. The Solgar option comes as capsules aimed at adults recovering from antibiotics or managing IBS symptoms. BioGaia uses a liquid dropper that parents give straight to newborns or infants for colic and gas relief. This makes the products target completely separate age groups and needs despite both scoring close overall with Solgar at 82/100 and BioGaia at 81/100.
Adults with bloating or irregular bowels should pick the Solgar product because it shows strong results for digestion and microbiome recovery after antibiotics and earns better marks for ingredient quality at 88/100 against 85/100. Parents of babies with colic will prefer BioGaia since its effectiveness hits 87/100 compared with 83/100 and the combined probiotic plus vitamin D3 saves hassle. Budget matters too as Solgar costs £25.49 while BioGaia sits at £28.23 yet offers less volume in the bottle.
Practical points include the dairy-free and vegan friendly nature of both which suits those avoiding milk. Solgar capsules have no reported taste issues though some find them a standard pill size. BioGaia drops mix easily with milk or water and cause no allergy problems for babies with cow's milk protein issues. The small 10ml bottle of BioGaia runs out quicker than expected for some users.

Advanced Multi-Billion Dophilus
Pros
- ✓Contains four well-researched, clinically validated probiotic strains (LA-5®, BB-12®, LGG®, L. casei 431®) with strong evidence for gut and immune support
- ✓Consistent user reports of reduced bloating, improved digestion, and more regular bowel movements
- ✓Effective after antibiotic use — multiple reviewers specifically note rapid microbiome recovery
- ✓No refrigeration required; dairy-free, lactose-free, casein-free, and vegan-friendly — suitable for sensitive and restricted diets
Cons
- ✗5 billion CFU per serving is moderate by current market standards — higher-CFU alternatives exist at similar price points
- ✗Price is on the higher end compared to generic probiotics, which some reviewers acknowledge
- ✗A minority of reviews appear to be for iHerb platform generally rather than this specific product, inflating the review signal
- ✗No prebiotic (e.g. FOS or inulin) included to support probiotic colonisation — some users may need a separate prebiotic
Best For
Protectis® Baby, Probiotic Drops...
Pros
- ✓L. reuteri DSM 17938 is one of the most researched probiotic strains specifically for infant colic and gut health — not a generic blend
- ✓Combines probiotic and vitamin D3 in one product; parents repeatedly cite this as a major convenience over managing two separate supplements
- ✓Dairy-free, lactose-free, and soy-free — suitable for babies with cow's milk protein allergy (CMPA), as confirmed by multiple reviewers
- ✓Neutral, oil-based taste accepted well by most babies; 5-drop dose is easy to give by spoon or mix into formula
Cons
- ✗10ml bottle is small and several reviewers find the price high relative to the volume, though most acknowledge iHerb pricing is significantly cheaper than local markets
- ✗No third-party testing certification — product quality relies on BioGaia's own standards
- ✗Colic relief is not guaranteed — at least one reviewer saw no improvement in colic symptoms, though digestion did normalise
- ✗No built-in dropper; the squeeze-tube design can feel fiddly for precise dosing
