Is Yakult suitable for...

  • Pregnant or breastfeeding women? Yakult can be drunk as part of a normal balanced diet, during pregnancy and breastfeeding. (Note that the UK's Department of Health and the HSE in Ireland recommend exclusive breast feeding for six months.)
  • Children? Yakult is not formulated for infants under six months of age and should not be used to replace breast milk substitutes or infant formula milk because Yakult alone will not provide the nutrients necessary for a child's growth and development. On occasions it may be appropriate for a healthcare professional to recommend Yakult for a young child. The product should then be taken in conjunction with the child's normal diet.
  • People with diabetes? Diabetes UK and Diabetes in Ireland have confirmed that people with diabetes can consume products such as Yakult. People with diabetes are recommended to follow a healthy balanced diet whereby no foods should be excluded. If a patient has diabetes and wishes to take Yakult it should be included in their carbohydrate calculations (see nutritional information); It may be better to choose Yakult Light and drink it with a meal. 
  • People on a kosher diet? No. Yakult does not have a kosher certificate.
  • People on a halal diet? The product is based on skimmed milk with no other animal products but Yakult does not have a halal certificate in Europe.
  • Vegetarians? Yes. The product is based on skimmed milk with no other animal products. It is not suitable for vegans.
  • People with lactose intolerance? Yakult contains very little lactose (approximately 1 g) so may be suitable for individuals who suffer from lactose intolerance. If a person is able to tolerate eating a yogurt, they should be able to tolerate a bottle of Yakult.
  • People with coeliac disease? Yes. Yakult is gluten-free (but not wheat free).
  • People with an allergy to dairy products? No. Yakult is made from fermented skimmed cows’ milk
  • Patients? Yakult is a food, not a medicine. Healthcare professionals may decide to give 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; some of these can be found in the scientific evidence section of this website. Please contact us for a list of studies that describe use of the product or strain (Lactobacillus casei Shirota) in seriously ill patients.


  • How many probiotic bacteria are in each bottle of Yakult? There is a minimum of 6.5 x109 (6.5 billion) live Lactobacillus casei Shirota in every bottle. The product undergoes stringent quality checks to ensure this.
  • Is Yakult a yoghurt drink? Yakult is a fermented milk drink, not a yoghurt, because it does not contain yoghurt starter cultures. The milk is fermented by the product's single bacterial strain: the probiotic and lactic-acid producing Lactobacillus casei Shirota.
  • How many bottles should be drunk per day? 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.
  • Does Yakult interefere with medication? Not to our knowledge. Yakult is a food that has been consumed for 80 years. There have been no reports of intereference with medicines reported from any human studies or from healthcare professionals. If you have any concerns, please contact us.
