Novalac AR infant formula is specially designed to help prevent regurgitations. Regurgitation is a common problem for formula-fed babies that can cause your baby discomfort and may interfere with digestion. Novalac AR contains a customized form of corn-starch that makes it easy for your baby to drink, but thickens when it reaches your baby's stomach. This thickening helps to prevent regurgitations. Novalac AR is easily digestible and is suitable for use as an alternative to standard formula in babies from birth to 12 months.
