Protectis® Baby, Probiotic Drops with Vitamin D, 0.34 fl oz (10 ml) vs Culturelle Digestive Health Daily Probiotic

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

Best For

Pros

• ✓LGG is one of the most clinically researched probiotic strains globally, backed by over 1,000 studies covering digestive health, antibiotic-associated diarrhoea, immunity, and infant eczema
• ✓Reviewers widely report reduced bloating, improved regularity, and relief from constipation — often within 1–2 weeks of use
• ✓Includes 200 mg inulin prebiotic to support LGG colonisation, improving on bare single-strain products
• ✓Small, tasteless, easy-to-swallow capsules with once-daily dosing; well tolerated across adult and paediatric users

Cons

• ✗Price per capsule sits above generic or own-brand multi-strain competitors, noted by several reviewers
• ✗Single-strain approach may be insufficient for those with complex dysbiosis or needing broad-spectrum microbiome support
• ✗Some users experience mild gas or gurgling in the first 3–5 days as an adjustment response
• ✗Contains sucrose and magnesium stearate — not ideal for those seeking the cleanest possible excipient profile
