Horlicks can be consumed during pregnancy, about once a day as part of a well-balanced diet is fine. However, Horlicks does contain vitamin A which some pregnant women choose to monitor over the course of their pregnancy. In the unlikelihood you suffer any ill effects from consuming Horlicks then we would recommend that you discontinue use immediately and consult your GP or obstetrician who will be able to advise you further. Please note that Horlicks should not be used as a breast milk (or infant formula) substitute, since it does not contain all the nutrients essential for a baby's healthy growth and development. Horlicks contains relatively high levels of dissolved solids with which the developing kidneys of a baby may be unable to cope. It is also recommended that milk should not be given as a drink to children under the age of 1 year.
