In a patient suspected of lactose intolerance, which supplement is advisable to prescribe alongside lactase supplementation?

1. Calcium

2. Pancreatase

3. Sevelamer

4. Sodium

The correct answer is: Calcium

In the case of a patient suspected of lactose intolerance, prescribing calcium alongside lactase supplementation is advisable due to the dietary implications of reducing or eliminating lactose-containing foods, which are significant sources of calcium. Lactose intolerance can lead to dairy avoidance, resulting in a potential deficiency in calcium, a vital mineral necessary for bone health and various physiological functions. Calcium supplementation serves to ensure that the patient maintains adequate bone density and overall health, particularly considering that dairy products are commonly consumed for their calcium content. Lactase supplements can help the patient digest lactose effectively, making it possible to consume lactose-containing dairy products if they choose to, but even with lactase, many patients might still reduce their dairy intake. Thus, the combination of lactase supplementation with calcium addresses both the symptom management of lactose intolerance and the prevention of potential nutritional deficiencies. This dual approach promotes overall health and dietary balance, particularly in individuals who may otherwise rely heavily on dairy for their calcium intake.
