A1 vs A2 Milk: Gut & Skin Health Secrets
13 Dec, 2025
Summary
- A2 milk from Indian cows may be easier to digest for some.
- A1 milk's peptide BCM-7 linked to health issues in some studies.
- Gut and skin health are interconnected via the gut-skin axis.
Milk, a staple nutritional source, is now understood to have variations impacting health, specifically A1 and A2 types. These differ primarily in their beta-casein protein composition and the breeds of cows from which they are sourced. While both are consumed similarly, their effects on the body, particularly gut and skin health, are a growing area of interest.
Vidhi Chawla, a dietician, notes that the distinction between A1 and A2 milk is gaining traction for its potential influence on digestive comfort and skin conditions. Some research suggests a link between A1 milk peptides and adverse health effects, though further studies are required to confirm these findings.
The interconnectedness of gut and skin health, known as the gut-skin axis, means that dietary choices like milk consumption could play a significant role. Individuals experiencing digestive or skin issues may benefit from exploring the potential impacts of choosing A2 milk over A1.
