Similac® Human Milk Fortifier Studies

Key Clinical Study Shows Important Gains in Growth1

Similac offers the FIRST nonacidified human milk fortifier that has extensively hydrolyzed protein.

  • Similac Human Milk Fortifier Hydrolyzed Protein Concentrated Liquid (HMF HP CL) infants gained 0.5 lb more weight at study day 29, and both groups increased in weight and length over time 

  • Similac HMF HP CL delivers 4.3g†  of protein (g/kg/day)

Evaluable patients (n = 75).

Features of Similac HMF HP CL

  • Extensively hydrolyzed protein source to help promote easy digestion

  • Has OptiGRO® for brain and eye development 

  • Low iron level provides flexibility to add iron as needed

Key Clinical Study Shows Tolerance1

Well tolerated

  • Only 1 in 66 (1.5%) NICU patients in the Similac HMF HP CL group discontinued due to feeding intolerance 

  • No incidence of metabolic acidosis with infants fed Similac HMF HP CL or control 

Improved protein status

  • Recent studies have identified blood urea nitrogen (BUN) levels of >9 mg/dL as an indicator of protein sufficiency in preterm infants2-4 

  • BUN levels remained above 9 mg/dL in preterm infant receiving Similac HMF HP CL

Mean BUN levels

Effects of an Acidic pH on Human Milk

In vitro study of human milk acidified with citric acid to a pH of 4.55

Similac HMF retains the pH of human milk to near neutral range, which should preserve the unique benefits of human milk.
