What is L. casei Shirota bacteria?

The bacteria in our little bottles is named after our founder, the Japanese scientist, Dr Shirota. Dr Shirota spent years researching intestinal bacteria, learning all about what makes them so great. In 1930, he successfully isolated and cultivated a unique strain of lactic acid bacteria that was robust enough to reach our gut alive. In honour of his achievements, the bacteria strain was named after him – thank you Dr Shirota!
