[Colief International Colief is clinically proven to significantly reduce crying time in colicky babies. Colief contains lactase, an enzyme naturally occurring in our bodies that helps break down complex sugar lactose found in milk, dairy products, breast milk and infant formulas. The technical name for this is Transient Lactase Deficiency. Colief Infant Drops can help the body break down the lactose into simpler sugars, glucose and galactose, making it easier for your baby to digest their feeds. Studies have shown that the hours of crying may be greatly reduced when babies are fed their usual milk treated with Colief Infant Drops.]
