Alpha-lactalbumin and early life nutrition
Rich in essential amino acids, alpha-lactalbumin is the most abundant whey protein in human milk, comprising around 25% of the total protein content1,2. Alpha-lactalbumin is a valuable ingredient in low-protein early life nutrition products, as it brings the protein content and composition closer to that of human milk.

Several clinical and pre-clinical studies have investigated the role of alpha-lactalbumin in early nutrition. Based on clinical investigations, it is believed that alpha-lactalbumin-enriched infant formulas may support age-appropriate growth2-8 and increase the energetic efficiency (growth per energy intake)4,9. Due to the high content of essential amino acids, alpha-lactalbumin can play a role in low-protein formulas, and the use of low-protein formulas has been suggested as a preventive strategy to reduce the risk of child overweight and obesity10-12.

Three clinical studies found that feeding infants alpha-lactalbumin supplemented formulas reduced feeding-related gastrointestinal events such as incidences of abdominal pain, constipation, vomiting and regurgitation, giving those formula-fed infants a similar gastrointestinal tolerance to breastfed infants enrolled in the studies2,3,13. In an infant rhesus monkey trial, alpha-lactalbumin was found to prevent E. coli-induced diarrhoea14. This enhanced protection against diarrhoea in rhesus monkeys is speculated to be linked to the presence of beneficial peptides15,16 or to alpha-lactalbumin’s suggested effect on reduction of growth of pathogens17-19.  

With our Lacprodan® ALPHA range, we offer a broad portfolio of alpha-lactalbumin-rich products.
