What is A2 Cow Ghee? A2 cow ghee is sourced from desi cows instead of crossbreed cows. These cows produce high-quality, protein-rich milk that is easy to digest. It improves appetite, strengthens memory, and contributes to skin health. This ghee contains A2-beta casein protein, which comes in two different forms. A1 beta-casein has histidine, while A2 beta-casein contains proline. One of the main reasons that A2 cow ghee is a superfood in many cuisines is the bilona process. This hand-churned process involves slow-cooking of the ghee to preserve the essential nutrients. Organic ghee has no machinery or preservatives, so the ghee quality differs from regular ghee in terms of taste, calories, and nutrition.
