This is a protocol for a Cochrane Review (intervention). The objectives are as follows:

To evaluate the efficacy and safety of higher protein intake versus standard and lower protein intake in formula-fed term infants, for the prevention of malnutrition in the form of undernutrition (underweight, stunting, or wasting) and overweight or obesity. We will include infants who are solely fed formula and those who are fed formula as complementary feeds.
