Protectis® Baby, Probiotic Drops with Vitamin D, 0.34 fl oz (10 ml) vs Optibac Probiotics Every Day

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
