Biofactors System™ of integrated nutrition is based on unique age-appropriate combinations of biofactors—nutrients and other ingredients that deliver functional benefits to the child. This is a special formula designed for infants with conditions such as prematurity following hospital discharge. It contains additional calories and protein to support growth and higher levels of some vitamins and minerals to meet the needs of premature infants and low birthweight babies when discharged from hospital. Consult your baby’s health care professional to determine when your baby is ready to switch formulas, and for advice on supplemental foods. He or she can recommend the most appropriate formula for your baby’s continued growth and development.
