1.	What is Lactobacillus casei Shirota strain? Lactobacillus casei are beneficial bacteria, which reach the intestines alive to favourably alter the balance of bacteria in the digestive system. Our unique, patented "Shirota Strain" is exceptionally acid resistant. It easily survives the journey through the gastric juices and bile acids produced during digestion to arrive alive in our intestine, helping to keep our digestive system working efficiently.
	2.	What is the role of Lactobacillus casei Shirota strain?
		•	To help normalise the balance of intestinal flora.
		•	To assist in regulating the peristaltic movement (natural rhythm) of the bowel.
		•	To help reduce detrimental substances produced by harmful bacteria.
	3.	How many bacteria are in a bottle of Yakult? There are 6.5 billion Lactobacillus casei Shirota strain in every 65ml bottle of Yakult.
	4.	If drinking Yakult for a long time, can the Yakult strain of bacteria become a permanent resident of the small intestine? No. Ingested bacteria cannot become a permanent resident of the human intestine. Ingested bacteria stays in the intestine for a short period of time before being excreted. To maintain a balance of intestinal flora, the bacteria need to be replenished on a regular basis.
