Acidophilus

Lactobacillus acidophilus is a species of bacteria that naturally occurs in the human gut and is also found in some fermented foods. 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 often grown in a laboratory setting for use in food products and supplements.

Acidophilus is added to foods as a live culture to provide probiotic benefits. It is most commonly found in fermented dairy products like yogurts and kefir, where it contributes to the characteristic tangy flavour and texture. It can also be found in some non-dairy fermented foods and supplements.

Lactobacillus acidophilus is not considered a food additive in the UK and therefore does not have an E-number. It is naturally present in the gut and consumed in fermented foods. Some research suggests that consuming live cultures like L. acidophilus may support gut health, but the evidence is mixed and more research is needed. EFSA has evaluated various strains of Lactobacillus for safety, often concluding they are safe for consumption in foods. No specific regulatory limits are set for its presence as a live culture in foods.
