What it is
Best known as a yoghurt starter culture, this probiotic produces lactase in the gut, making it genuinely helpful for lactose intolerance. Usually included in multi-strain blends rather than sold alone. Very safe with a long history as a food organism. Less standalone clinical evidence than Lactobacillus strains.
