Yakult is a fermented milk drink, which contains Lactobacillus casei Shirota. This bacteria strain is unique to Yakult and is scientifically proven to survive the gastrointestinal tract.

There is a minimum of 6.5 x109 (6.5 billion) colony forming units (CFUs) of Lactobacillus casei Shirota in every 65ml bottle. The product undergoes stringent quality control checks to ensure this.

One bottle a day is generally recommended. It is fine to drink more than this, as may be recommended by healthcare professionals at their discretion for certain conditions. For optimum benefit, the product should be consumed every day.

Yakult is a fermented milk drink and not a yoghurt, because it does not contain yoghurt starter cultures (Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus). The milk is fermented by the product’s single bacterial strain; the probiotic and lactic-acid producing Lactobacillus casei Shirota.

Although Yakult is a food and not a medicine, healthcare professionals may decide to recommend or prescribe probiotics to patients, to help maintain gut health and function, and to help reduce the risk of illness. Many scientific publications describe the use of Yakult in patients, which can be explored further in the research section of this website.

To our knowledge, Yakult does not interfere with the efficacy of any medication.

Children can drink Yakult as part of a healthy balanced diet once they are introduced to solid foods. Yakult should not be used to replace breast milk or infant formula milk. On occasions it may be appropriate for a healthcare professional to recommend Yakult for a young infant or child. The product should then be taken in conjunction with their normal diet and we advise that it is diluted and a smaller amount given.

Yakult is suitable for people with diabetes, as part of a healthy balanced diet. If a patient who has diabetes would like to have Yakult this should be incorporated as part of their carbohydrate intake (see nutritional information). It may be better to choose Yakult Light and drink it with a meal.
