Confirm whether vitamin D is included
BioGaia sells drops with and without vitamin D. Its professional brochure describes the vitamin D version as adding 10 mcg per five drops and specifies full-term babies. Have the infant’s clinician review use, particularly for premature or medically vulnerable babies, and avoid inadvertently duplicating a separate vitamin D dose. [1][2]
Follow the package’s dispensing method
The inspected UK instructions say to shake for 10 seconds and give five drops once daily. They allow a sterile spoon or addition to breast milk or formula, and advise against dispensing directly from the bottle into the mouth. Do not add to hot food or drinks. [3]
Prepare a dose that will actually be received
Imagine mixing drops into a large feed that the baby may not finish. A clinician or pharmacist can help choose an appropriate administration method so the intended dose is received. Follow local package storage instructions; the UK FAQ advises against freezing. These directions do not establish a need for every baby to take probiotics. [4][5]
