Question: what is the difference between whole milk and a2 milk?
Answer: Regular milk contains both A1 and A2 beta-casein, but A2 milk contains only A2 beta-casein. Some studies suggest that A1 beta-casein may be harmful and that A2 beta-casein is a safer choice. ... A2 milk is produced and marketed by the A2 Milk Company and contains no A1 beta-casein.
