Bifidobacterium longum

Bifidobacterium longum is a type of bacteria naturally found in the human gut. It is a probiotic, meaning it is a live microorganism that, when administered in adequate amounts, confers a health benefit on the host. It is typically cultured in a laboratory setting for use in food supplements and other products.

B. longum is primarily used as a probiotic ingredient in foods and supplements intended to support gut health. It is often added to dietary supplements, such as those marketed for gut support or general wellness. It may also be incorporated into certain fermented foods or functional food products.

Bifidobacterium longum is not a food additive and therefore does not have an E-number or require authorisation on the Register of Food Additive Authorisations. It is a live microorganism commonly consumed in probiotic supplements. Research into the effects of probiotics like B. longum is ongoing, with some studies suggesting potential benefits for gut health and the immune system. However, evidence can be mixed, and individual responses may vary. It is not associated with notable controversies regarding its safety as a food ingredient.
