Alpha-lactalbumin is ideal for low protein infant formula.

Protein in infant formula – Alpha-lactalbumin

Low protein infant formula

Alpha-lactalbumin is rich in essential and conditionally essential amino acids and is the dominant protein in human milk, comprising 25-35% of the total protein content. We have two alpha-lactalbumin enriched products in our infant portfolio. These are marketed as Lacprodan® ALPHA-10 and Lacprodan® ALPHA-20 and can be used within the areas of humanisation, gastrointestinal health, low protein and comfort formulations.

Protein for infants

These products are ideal for low protein infant formulas due to the high content of essential amino acids. Low protein formulations are associated with reduced risk of obesity in infancy, childhood, and adulthood. So by adding alpha-lactalbumin the overall protein content of infant formula can be reduced and thereby mimic human milk in terms of protein concentration.

Several clinical studies have investigated the functionality of alpha-lactalbumin and identified important benefits for infant nutrition, development, and health. One of the observed effects when using alpha-lactalbumin in infant formulas is an infant growth curve more similar to that of breastfed infants.

Protein in infant formula reduces gastrointestrial problems

Several infant clinical studies have demonstrated that an alpha-lactalbumin enriched infant formula reduces feeding-related gastrointestinal events in a manner similar to breastfeeding. In regards to comfort formulations, alpha-lactalbumin enriched infant formulas is better accepted and tolerated by the infants than a conventional infant formula. The protein for infants, alpha-lactalbumin has also been shown to reduce gastrointestinal problems, such as constipation, reflux, and vomiting. Finally, it prevents E. coli induced diarrhea, as demonstrated in an infant rhesus monkey trial and has a bifidogenic effect. 

Benefits associated with alpha-lactalbumin:

  • High content of essential amino acids making it a key ingredient in low protein infant formulas
  • Reduces gastrointestinal events
  • Protects against intestinal infections
  • Support a healthy gut flora making it an ideal ingredient for comfort formulations

Using infant formulas is second to breastfeeding, a fact supported by WHO.
