LCS (Lactobacillus casei strain Shirota) Benefits

Yakult's exclusive Probiotic strain is known as LcS ( Lactobacillus casei strain Shirota). LcS represents one of the natural lactic acid cultures (bacteria). Lactic acid cultures have been used for more than a thousand years (since the ages of Ramayana and Mahabharata) to ferment milk for preparing dahi or curd. The safety of LcS has been proven with more than 80 years of safe use in the world.

All lactic acid bacteria do not qualify as Probiotic since Probiotics need scientific data to substantiate their health benefits. That is why we can not call normal dahi as Probiotic products although they have important nutritional benefits.

Yakult has been granted the FOSHU (Food for Specified Health Uses) label from the Consumer Affair Agency, Gevernment of japan. This label is given to only those products whose safety and health benefits have been scientifically proven.


Recently, LcS has received the GRAS (Generally Regarded As Safe) certificate from the Food Drug Authority in United States of America (USA). A Certificate from this authority means the highest level of safety for any product.

The story behind LcS: Prevention is better than Cure

Dr. Minoru Shirota was born in 1899 in japan when people suffered from infectious diseases. He believed that "Prevention is better than cure" and "healthy intestine leads to a long life". After long years' research in the laboratory, he isolated LcS, in 1930, form more than 300 lactic acid bacteria. LcS helps improve the functioning of the digestive system and helps build immunity. In 1935, he developed the probiotic fermented milk drink "Yakult" with LcS and started to market it in japan. Now more than 30 million people around the globe enjoy drinking it everyday.
