Lactobacillus casei Sour bacterium – healthy, versatile and everywhere

Your body is home to billions of microbes. One of them is Lactobacillus casei, a lactic acid bacterium. You’ll find it in your gut – and in yoghurt, sauerkraut and other fermented foods. A microbe that lives both inside you and on your plate.

A tasty little bacterium

Few microbes are as versatile in food as L. casei. It’s found in fermented dairy products, but also in salami, pickled vegetables, sourdough bread – even wine. This bacterium turns sugars into lactic acid, creating a sour environment that’s hostile to many other microbes. The result: food that stays fresh longer, with a tangy twist.

Living in your belly

When you eat fermented products, you’re also consuming microbes. Some, like L. casei, survive the journey through your stomach and settle in your intestines. There, they can support the balance of your gut microbiome. These are called probiotics. A diverse microbiome is key to good health – and L. casei helps maintain that diversity.

Good food for good microbes

The microbes in your gut don’t just sit there – they protect you. They train your immune system and keep harmful invaders at bay. Simply by taking up space, they prevent pathogens from settling in. Want to help them out? Feed them well. A fibre-rich diet keeps your gut microbes healthy. And a serving of yoghurt or sauerkraut now and then? Delicious – and good for you.
