Beta-Casein Variants: Genetic Polymorphism and Physical Properties
Research on the genetic polymorphism of beta-casein variants (A1, A2, B, I) and their impact on milk properties, cheese-making, yogurt texture, coagulation and dairy-product quality.

All studies →Circulatory amino acid responses to milk consumption in dairy and lactose intolerant individuals
In all participants across all milk types, plasma AA concentrations (AUC0-180) increased after milk ingestion with no significant differences in responses observed between milk types or participants (P > 0.05), with the exception of the suppressed lysine response in the DT group following A2M ingestion, relative to the other two groups and milk types (P < 0.05).
A2 Milk Enhances Dynamic Muscle Function Following Repeated Sprint Exercise, a Possible Ergogenic Aid for A1-Protein Intolerant Athletes?
Following muscle-damaging exercise, ingestion of 500 mL of A2 or regular milk can limit decrements in dynamic muscle function in male athletes, thus hastening recovery and improving subsequent performance. The findings propose A2 milk as an ergogenic aid following EIMD, and may offer an alternative to athletes intolerant to the A1 protein.
