India, Aug. 9 -- Along with dairy milk, there are several milk varieties, including vegan alternatives to lactose-free options. A new type of milk gaining attention on social media is A2 milk, which stands out due to its unique protein profile. Interest in A2 milk is rising steadily, with a recent report by Future Market Insights showing the market is expected to grow from around USD 2.44 billion in 2025 to USD 5.78 billion by 2035, at a CAGR of 9.0%. A2 milk is a type of cow's milk that contains only the A2 beta-casein protein, unlike regular milk, which has both A1 and A2 proteins. Suvarna Sawant, chief Dietitian, Nanavati Max Super Speciality Hospital, Mumbai, says, "A2 milk is derived from specific cow breeds like Gir and Sahiwal." Traditional cow's milk has two types of beta-casein proteins: A1 and A2. "Most modern breeds, like Holsteins, produce a mixture of both. However, A2-only milk is sourced from cows genetically bred to produce only the A2 variant," shares dairy expert Ravin Saluja. As for the taste, A2 milk is similar to conventional milk. The differences only stem from breed of cow and what they eat, not the protein. This milk offers digestive relief to some people but is not lactose-free. The dietitian cautions it's not suitable for lactose-intolerant individuals, but may help those feel a mild digestive discomfort from regular milk. People who are sensitive to lactose, fitness enthusiasts and health-conscious families prefer A2 milk for its better digestibility. Those experiencing bloating or discomfort from regular milk may find A2 easier to digest as well. Likewise, A2's clean protein profile aids in muscle recovery without gut upset. As for parents of toddlers or those families who have elders can also include A2 milks in their meal rotation....
