Commercially available lactase in tablet or liquid form is another means to improve lactose digestion (1, 2). The liquid enzyme is added to milk and it hydrolyzes 70% of the milk sugar within 24 hours. This lactose-reduced milk has been shown to be almost as effective as yogurt in reducing symptoms of lactose intolerance. Although these lactose-reduced products are beneficial for lactose maldigesters, they are generally unnecessary if milk is consumed in moderate amounts, and combined with other foods (2).
