Cow's milk intolerance can be caused by various conditions such as galactosemia, lactose intolerance, or allergy to cow's milk protein:

• Lactose intolerance: Lactose intolerance can be caused by a deficiency of the enzyme lactase, which is involved in breaking down lactose. Lactase deficiency leads to gastrointestinal disturbances such as diarrhea after consuming lactose-containing foods (e.g., dairy products). Replacing lactose with other carbohydrates significantly contributes to improving gastrointestinal symptoms and normalizing digestion.
• In galactosemia: Galactosemia is a disorder in which galactose metabolism is impaired and requires a lifelong restriction of galactose intake. Since galactose is a natural component of lactose (milk sugar), dairy products should be avoided.
• For cow's milk protein allergy: If you have a cow's milk protein allergy, foods containing intact animal milk proteins should be strictly avoided. In addition to highly hydrolyzed or amino acid-based formulas, a special soy-based formula is a suitable alternative.

Affected infants require individual nutrition, as cow's milk-based formulas cannot be used.
Humana SL is a special formula based on soy protein isolate, suitable for feeding infants with an intolerance to cow's milk due to various causes.
