It helps maintain friendly gut flora, including during and after a course of antibiotics, supports immune system health, and helps reduce the occurrence of symptoms of upper respiratory tract infections in adults. It is for adults only and suits vegetarians and vegans. It is stored below 25°C, so it does not need the fridge, and it costs about $0.63 a day in the 50-capsule pack.

Lactobacillus Acidophilus
What is Lactobacillus acidophilus used for?
People often take Lactobacillus acidophilus to help their gut bounce back after a course of antibiotics. It's one of the best-known everyday probiotic species, with a long history in fermented foods.

Is this the right probiotics for you?
Common questions
Does Lactobacillus acidophilus do anything on its own?
It's a well-established species with a long history in fermented foods. Antibiotics clear out plenty of your gut bacteria along with the infection, and a major review found probiotics as a group lower the risk of diarrhoea linked to antibiotics. That evidence is low certainty, though, and it combines many different strains and species. The plain species hasn't been through its own dedicated clinical trial the way some specific named strains have.
What's the difference between acidophilus and a strain like DDS-1?
Acidophilus is the species name, and DDS-1 is one specific, named strain within it that has its own clinical trials, including one for IBS-related tummy pain. A product labelled just 'acidophilus', with no strain code, is the species in general, and that trial evidence doesn't carry over to it.
