Yakult is the original probiotic. One bottle contains a minimum of 6.5 billion cells of the unique probiotic strain of bacteria isolated by Dr Shirota. The strain is scientifically proven to reach the intestines alive where it can top up the existing levels of good bacteria. There are absolutely no colourings whatsoever in Yakult. Its colour is a natural result of caramelisation during the production process.

Today, there are two different types of Yakult available in the UK; the original version (in the red packaging) and Yakult Light (in the blue packaging). The Light version contains less sugar – but other than that they are essentially the same – and, most importantly, both are guaranteed to contain at least 6.5 billion bacteria per bottle.

Yakult's natural home is in the digestive system – along with the 100 trillion bacteria (the 'gut flora') already residing there. Since the digestive system is the location for most of the body's immune system, it's important that a healthy balance of bacteria is maintained there. Yakult helps to top up and support the work of beneficial bacteria in the gut.
