How does drinking Yakult increase bacteria in the gut?
Drinking Yakult doesn’t just add billions of these unique L. casei Shirota bacteria to the gut; it boosts the growth of other bacteria too!* Get sipping and let the gut party begin!
Yakult Original is a delicious fermented skimmed milk drink developed over 90 years ago in Japan. Each bottle, with its iconic design inspired by Japanese tradition, is full of science. In fact, it contains more than 20 billion L. casei Shirota probiotic bacteria, which survive the gastric barrier and reach the intestines alive. These exclusive probiotic strains help support the balance of the intestinal flora and increase the number of beneficial bacteria in the gut.
To talk about the origins of Yakult, we need to go back in time to Japan in 1899, where Minoru Shirota was born—scientist, microbiologist, and founder of Yakult.

What is L.casei Shirota?
What’s so special: 20 billion active lactic acid bacteria reach your gut alive. Mission accomplished!
Your gut hosts a unique community of bacteria that influence digestion, immunity, and even mood. Good and bad bacteria constantly battle, affecting overall health. The gut produces 70-80% of immune cells and even helps regulate serotonin, the happiness hormone. This “superorgan” plays a crucial role in keeping you healthy, but stress, poor diet, and antibiotics can disrupt it. To support your gut, eat a varied diet rich in probiotics and fiber, manage stress, and stay active: because a happy gut means a happy you!
