Probiotics for the gut flora

Prepared by the LekCheck team · Last reviewed: 2026-06-29 · How we create our content

Probiotics contain beneficial microorganisms and are often used to support the gut flora, for example when taking antibiotics or after an upset stomach. The effect depends on the type and strain, and the benefit is individual. Below you can compare products and prices. For persistent digestive complaints, consult a doctor.

When they are used

Probiotics are often taken during and after a course of antibiotics or for mild digestive complaints. They are taken according to the directions on the pack; with an antibiotic, an interval between the two doses is usually kept.

What to bear in mind

Probiotics do not treat infections and do not replace prescribed therapy. With a weakened immune system or serious illness, consult a doctor before taking them.

When to see a doctor

See a doctor for prolonged diarrhoea or constipation, blood in the stool, severe abdominal pain, fever or weight loss — to establish the cause, rather than relying on probiotics alone.
