Lactobacillus Gasseri

Lactobacillus gasseri is a type of probiotic bacteria, a live microorganism that, when administered in adequate amounts, confers a health benefit on the host. It is naturally found in the human gut and vagina, and can also be cultured in laboratories for use in food and supplements.

Manufacturers add Lactobacillus gasseri to foods and supplements as a live culture, aiming to provide potential health benefits associated with probiotics. It is most commonly found in dietary supplements, but can also be incorporated into fermented foods like yoghurts or ice cream.

Lactobacillus gasseri is not an authorised food additive in the UK and does not have an E-number. It is often consumed as a dietary supplement, with some research suggesting potential benefits for gut health and other areas. However, scientific evidence for specific health claims can be mixed, and more research is often needed to confirm these effects. EFSA has evaluated various strains of Lactobacillus for specific uses, but regulatory status for general food use as a probiotic ingredient is distinct from additive authorisation.
