Please note: This is a food supplement and is not intended to prevent, treat or diagnose any medical conditions.

Instructions For Use

Food supplement suitable for infants (from birth), children and adults.

Preparation: - Simply mix with your child's favourite foods or drinks - sprinkle the powder over cereal, mix in with yoghurt or dissolve in a glass of water or cold milk. - Can be taken with formula milk - simply add to the bottle once it has cooled down to room temperature (as heat reduces the viability of natural bacteria). - For breastfed babies, powder can be applied to nipple or clean finger for baby to suckle. - Adults & children should ideally drink plenty of water during a course of live cultures. - Best taken with a meal, preferably with breakfast.

Recommended amount:

  • Infants from birth to 3 years: 1 sachet per day
  • Kids 4 - 12 years: 1 to 2 sachets per day as desired
  • Pregnant and breastfeeding mothers: 1 sachet per day

Live cultures are not recommended for those with serious medical conditions e.g. those who are severely immunosuppressed, have pancreatitis, are in the ICU, have melaena, have a central venous catheter, infants with short bowel syndrome, or patients with open wounds following major surgery; unless under a doctor's care.
