Casida Lactobacillus Gasseri contains carefully selected lactic acid bacteria that are a natural component of the human gut flora. The capsules have been developed with pharmaceutical care and contain a highly concentrated amount of active bacterial cultures, protected by a stomach acid-resistant capsule shell.
The included cultures are stable and ensure high viability all the way to the intestine. The formulation is complemented by Biotin, which contributes to normal energy metabolism and supports the maintenance of normal mucous membranes – including the intestinal mucosa. Thus, the product combines natural ingredients with scientifically proven quality.
Casida stands for tested quality, sustainability, and responsibility. Our dietary supplements are developed according to the highest standards and are made exclusively with carefully selected raw materials. We consistently avoid artificial colors and preservatives as well as animal testing.
Available in many pharmacies – including yours.

The Lactobacillus gasseri strain occurs naturally in breast milk. These lactobacilli colonize the intestines and genitals of women. Various studies have examined the effect of these lactobacilli on female metabolism, particularly investigating potential positive effects of these microorganisms on weight control. The cited studies suggest that Lactobacillus gasseri may be able to reduce body fat in obesity.1, 2
A Japanese double-blind study in 2011 investigated potential positive effects on weight loss. 210 adults with abdominal obesity participated. They received Lactobacillus gasseri as a dietary supplement for three months. Reductions in body mass index (BMI) and waist and hip circumference were observed. Abdominal fat was reduced by 8.5% in the experimental group. In the control group, there were only minor changes in body weight and body fat. Further research is needed.3
