- Conclusion
  One RCT examining very low birthweight (VLBW) infants in the newborn intensive care unit (NICU) determined that formula enrichment with eight grams per L of protein, and micronutrients (but not calories) may increase lean body mass in males and females and decrease body fat in girls, compared to standard formula after four months.

- Conclusion
  In two RCTs with post-discharge very low birthweight (VLBW) infants, enrichment of iso-caloric formula with protein and micronutrients increased bone mineral content and accretion after two to four months, however, in one study the difference between groups was not significant after a two-month follow-up.
