How does Lactobacillus gasseri differ from other probiotics, and why choose this particular species?

Probiotics are not a uniform group: different bacterial strains act differently and are studied in different contexts. Lactobacillus gasseri belongs to the lactobacilli — microorganisms that are normally present in the human gastrointestinal tract. It is chosen primarily to support the balance of the intestinal microflora.

Its mode of action is linked to the production of lactic acid: this creates an environment less favourable to the overgrowth of unwanted microorganisms and helps the intestinal mucosa stay in a more stable condition.

A separate point that draws attention to this species is its link with leptin, a hormone involved in regulating appetite and energy metabolism. This does not make the product a weight-loss aid, but it may be of interest to those who want to take a comprehensive approach to gut health and eating habits.

The capsules are vegetarian, which is convenient for taking as a course. The product is intended for adults only. If you take medicines, have a health condition, or are pregnant or breastfeeding, you should consult a doctor before you start taking it.
