Colief Infant Lactase Enzyme Drops (15ml). Milk, infant formulas, breast milk, and dairy products all contain a complex sugar (disaccharide) called lactose.. Lactase is the enzyme our bodies need to produce to break down the lactose in milk and dairy products into the simple sugars (monosaccharides) glucose and galactose.. These can then be absorbed as part of the normal digestive process.
