Novalac AR1 For Reflux Management From Birth Until 6 Month is a pre-thickened formula specially designed to manage reflux. Most babies tend to spit up after every feeding. This is due to the return of the milk from the stomach up to the mouth. It is certainly smelly and unpredictable, but still normal. Novalac AR contains a special form of corn starch that thickens once it reaches your baby’s stomach. This thickening in the stomach helps to prevent the return of milk up to the mouth. It is easy to drink as it does not get thick in the feeding bottle. This milk formula is nutritionally complete, thus, can replace a regular formula and ensures optimal growth.
