Antibiotics are widely used to treat bacterial infections, but their use can negatively impact digestive health. One such consequence is secondary lactase deficiency, a condition resulting from antibiotics' harmful effects on the small intestine. This article explores how antibiotics affect lactase production, explains why probiotics fail to address lactose intolerance effectively, and outlines how Mamalak can help the body restore healthy digestion.
How Do Antibiotics Cause Secondary Lactase Deficiency?
Antibiotics eliminate pathogenic microorganisms but also inadvertently destroy beneficial bacteria that maintain gut balance. This disruption impairs the functioning of the small intestine, where lactase—the enzyme required for lactose digestion—is produced. As a result, symptoms such as bloating, diarrhea, nausea, and abdominal pain may occur.
Why Don't Probiotics Solve the Problem?
Probiotics are frequently recommended alongside antibiotics to help restore gut flora. However, their benefits are largely confined to the large intestine, whereas lactase deficiency originates in the small intestine. Until normal function in the small intestine is restored, probiotics alone cannot resolve lactose intolerance.
Without normal lactase activity in the small intestine, large amounts of undigested lactose continue moving into the initial sections of the large intestine. There, fermentation occurs, dysbiosis persists, and chronic inflammation may develop.
How Does Mamalak Work for Lactase Deficiency?
Mamalak, produced by Vorwarts Pharma, is a certified European solution specifically formulated for individuals with lactose intolerance. Its active ingredient, lactase, efficiently breaks down lactose into glucose and galactose, facilitating easy absorption and effectively eliminating unpleasant symptoms associated with consuming dairy products.

Benefits of Mamalak:
- Safe for both children and adults.
- Highly purified, minimizing the risk of allergic reactions.
- Fast-acting, providing relief immediately after intake.
- Supports the body's natural digestive processes.
- Available in convenient forms—drops and capsules.
- Neutral taste, easy to add to food and beverages.
Where to Buy Mamalak?
Mamalak is available in numerous pharmacies and through popular online platforms partnered with Vorwarts Pharma, such as Rozetka, Tabletki, and FoodSup.
Secondary lactase deficiency caused by antibiotic use is a serious issue that should not be overlooked. It's essential not only to restore the microbiome in the large intestine but also to normalize small intestine function. Without addressing this aspect, probiotics alone will not yield the expected benefits. Mamalak is an effective solution to alleviate symptoms of lactase deficiency, restoring comfort and enjoyment in consuming dairy products.
