Colief Infant Drops Colief Infant Drops help to relieve colic in babies from birth onwards. The active ingredient is lactase, a naturally occurring enzyme that we all need to break down lactose, found in breast milk & most infant milk formulas, into the simple sugars glucose & galactose which can then be absorbed as part of the normal digestive process. Lactase deficiency in newborn babies can lead to temporary digestive discomfort (bloatedness, wind & griping pain), which results from undigested lactose in food. This can be an important factor in some babies with colic. Colief Infant Drops compensate for a possible temporary lactase deficiency in the baby's digestive system, by breaking down most of the lactose before the baby is fed to make it more digestible. Studies have shown that the hours of crying may be greatly reduced when a baby's usual milk is treated with Colief Infant Drops. Colief Infant Drops are sugar free & are suitable for vegetarians.
