Nan Optipro Formula Milk in Singapore VS in Malaysia

Hi mummies, Any difference in ingredients for Nestle Nan formula milk selling in Singapore and Malaysia? Looks like Malaysia is selling Nan Pro and Spore is selling as Nan Optipro.. a bit confused whether they are the same? My LO is currently 5m+ and had been taking Nan Optipro SG version. As he is going to switch to stage 2 of FM soon, i am thinking to buy from Msia as much more cheaper. Any sharing will be greatly appreciated!! #firsttimemom #firstbaby #milk
