Hi zaharaddeen, Welcome to HCM. Bournvita is nothing but a food supplement. It has no special action in pregnancy as compared to non pregnant women. In pregnancy protein, fat, carbohydrate, vitamin, mineral etc. requirement is much more than in non pregnant lady. Bournvita or for that matter any food supplement can contribute to that extra requirement. In pregnancy what we particularly supplement is folic acid, iron and calcium. If the pregnant lady is thin built and does not take adequate food then protein supplements are also advised. In fact if one has nutritious well balanced diet all of the above mentioned items is unnecessary.
