Pros
- Tested in thousands of babies across high-quality trials
- Focus on gut microbiome development, immune support, and allergy prevention
- Vegan-certified, free from dairy, soy, gluten, sugars, artificial colors
- Suitable from birth, including premature babies under supervision
- Can be fed directly from the dropper
Cons

Live B. breve M-16V colonizes the infant gut and increases beneficial Bifidobacteria levels. The strain supports digestive health and gut flora balance, and may reduce colic symptoms as the microbiome stabilizes.
