It is produced in the small intestine and is necessary for the digestion of lactose in individuals who have sufficient lactase activity.
Benefits
- Used in various industries including food, pharmaceuticals, and dairy processing to produce lactose-free or reduced-lactose products for individuals with lactose intolerance.
- Enables lactose-intolerant individuals to enjoy dairy products without experiencing gastrointestinal discomfort such as bloating, gas, or diarrhea.
- Facilitates the production of lactose-free infant formula for babies who are unable to digest lactose properly, providing them with essential nutrients found in milk.
Precautions
- Individuals with lactose intolerance should be cautious when consuming products containing lactase, as it may not completely eliminate all lactose and some individuals may still experience symptoms.
- Excessive consumption of lactase supplements may lead to an imbalance in gut microbiota or gastrointestinal upset in some individuals.
Fun fact
Lactase activity tends to decrease with age in many individuals, leading to lactose intolerance later in life. This phenomenon is known as primary lactase non-persistence and is common among certain ethnic groups.
