What Is Beta-Lactoglobulin?
Beta-lactoglobulin (β-lactoglobulin) is a major whey protein found in the milk of many mammals, particularly cows. Beta-lactoglobulin is rich in essential amino acids and has a high nutritional value, making it a popular ingredient in dietary supplements and infant formulas. It is also noted for its potential allergenic properties, which can cause allergic reactions in some individuals[2].
Beta-Lactoglobulin and Whey Protein
Beta-lactoglobulin is a key component of whey protein[3], which is the liquid remaining after milk has been curdled and strained during cheese production. Whey protein is highly valued for its excellent amino acid profile and digestibility, making it a popular supplement among athletes and bodybuilders. Beta-lactoglobulin contributes significantly to the nutritional benefits of whey protein, providing essential amino acids that support muscle repair and growth[4]. Additionally, its high bioavailability ensures efficient nutrient absorption. Despite its benefits, individuals with dairy allergies should exercise caution, as beta-lactoglobulin can trigger allergic reactions in sensitive people.
