Our gentle, yet potent Infant Probiotic powder is created in small batches especially for your baby's developing digestive system. This pure, custom blend contains seven clinically-proven probiotic strains that are naturally found in healthy infants — to help colonize little intestines with beneficial bacteria from the get-go. It also supports immunity, may help with common baby digestive issues like reflux (GERD), occasional diarrhea and constipation, and even skin issues like eczema.* Bifidobacterium infantis, a strain that dominates in breastfed babies' intestines, comprises 50% of our formula, as studies show it supports healthy digestion, growth and a robust immune system.* Does not contain certain strains (or prebiotics) found in other commercial brands that can cause histamine intolerance, d-lactic acidosis or other adverse reactions. No common allergens, additives or fillers. All strains are non-gmo. All you get are safe, natural baby probiotics!
