Dietary treatment of infant colic BiGaia relieves infant colic with excessive crying in breastfed babies. The lactic acid bacteria Lactobacillus reuteri Protectis helps to build a balanced intestinal flora. Application: Add 1x 5 drops to 1 teaspoon of breast milk. Shake the bottle vigorously before each use until the sediment is evenly distributed. Hold the opened bottle vertically with the dropper pointing downwards, then the drops will come off easily. Note: Do not mix BiGaia with hot foods and do not take it at the same time as antibiotics, as this can damage the lactic acid bacteria.
