Eh, I haven't tried Efferty myself, tapi a few of my mum friends mentioned it before, mostly positive lah, tapi flavour preference very personal kan. Strawberry usually safer bet because chocolate sometimes a bit too rich for some mums, tapi if you like chocolate normally, probably okay je. Best to try small carton first to see how your body reacts, since setiap orang berbeza especially during pregnancy or breastfeeding!
