From the Research

For pediatric lactose intolerant patients, the recommended lactase enzyme dosage is typically 3,000-6,000 units per meal containing lactose, with adjustments based on the child's age and the amount of dairy consumed. This dosage is supported by various studies, including one from 2021 1, which highlights the importance of proper lactase enzyme supplementation in managing lactose intolerance. The lactase enzyme works by breaking down lactose (milk sugar) into simpler sugars (glucose and galactose) that can be easily absorbed by the intestine, preventing symptoms like gas, bloating, abdominal pain, and diarrhea.

Key Considerations

  • For infants and very young children, 3,000 units is often sufficient, while older children may need up to 6,000-9,000 units for larger meals with high lactose content.
  • Lactase supplements come in various forms including drops, chewable tablets, and capsules.
  • The supplement should be taken just before consuming dairy products for maximum effectiveness.
  • Parents should start with a lower dose and adjust as needed based on symptom control.
  • It's essential to note that lactase supplements are generally considered safe with minimal side effects, but consulting with a pediatrician before starting any supplement regimen is recommended, especially for very young children.

Additional Therapeutic Options

  • Besides lactase enzyme supplementation, other therapeutic options include the use of probiotics and prebiotics, as well as dietary modifications such as consuming lactose-free foods or dairy products with lower lactose content 2, 3.
  • The use of probiotics and prebiotics may help alleviate symptoms of lactose intolerance by modulating the gut microbiota, although more research is needed to fully understand their effects 3.
