What is the best first formula for a baby?

It all depends on the reason for which the baby was introduced to formula milk - perhaps it is malnutrition, food intolerance or allergy. In this case, a different milk is used for each of these disorders. Here you can find examples broken down into specific "problems" of the child:

If you simply don't want to breastfeed your baby and want to introduce substitute nutrition, basic milks, which can be bought in pharmacies without a prescription, will suffice. All of them ensure an adequate supply of nutrients and are adapted to EU standards - the composition of all milks available on the market must be subject to appropriate standards in order to be sold in a pharmacy.

Here you can compare the prices of these preparations in online pharmacies and order with home delivery or pick-up at the pharmacy:
