What Exactly is A2 Greek Yogurt?

A2 Greek yogurt is a cultured dairy product made from milk that contains only the A2 beta-casein protein. The key difference lies in the genetic makeup of the cows producing the milk. Modern dairy herds, particularly those from European stock like Holsteins, often produce milk with a mix of A1 and A2 beta-casein. A genetic mutation thousands of years ago led to the development of the A1 protein variant. In contrast, certain indigenous breeds of cows (like Sahiwal and Gir) and other mammals (like goats, sheep, and buffalo) naturally produce milk with only the A2 protein.

When digested, the A1 protein can release a peptide called beta-casomorphin-7 (BCM-7), which some research suggests may contribute to digestive discomfort in certain individuals. The A2 protein, on the other hand, is not associated with this peptide release, leading to fewer reported digestive issues for some people who are sensitive to A1 protein. A2 Greek yogurt applies this principle to the strained, protein-dense yogurt beloved for its thick texture and tang. The straining process further concentrates the protein, so using A2 milk for this product is a logical step for brands catering to those with digestive sensitivities.

Finding A2 Greek Yogurt: Brands and Sources

While not as widely available as conventional Greek yogurt, A2 Greek yogurt is increasingly found in health food stores, online marketplaces, and from local farms specializing in A2/A2 dairy. The market includes both large-scale commercial products and small-batch, artisanal options, often from farms committed to organic, grass-fed practices.

• Nounós Creamery: This brand was one of the first to introduce A2 Greek yogurt to the U.S. market. It is often found in reusable glass jars and comes in a variety of flavors.
• Alexandre Family Farm: Known for its organic A2/A2 milk, this company also offers yogurt products made from their A2/A2 dairy.
• Miller's Bio Farm: This farm offers raw, pasteurized, and Greek A2/A2 yogurt products. They often provide delivery services and cater to those seeking ethically sourced, non-GMO dairy.
• Buffalo Valley Pastures: This farm provides grass-fed, A2/A2 Greek yogurt made from their own herd, with an emphasis on raw, probiotic-rich products.

How to Identify Authentic A2 Greek Yogurt

1. Check the label: Look for explicit claims like “A2,” “A2/A2,” or “Made with A2 Milk”.
2. Research the brand: Investigate the company's sourcing methods. Reputable brands will be transparent about their cow genetics, often noting that their herds have been genetically tested.
3. Inquire at local farms: Many smaller, local farms now specialize in A2/A2 dairy. They are often the most reliable source for high-quality, authentic products.

The Potential Digestive Advantages of A2 Greek Yogurt

For some individuals, the primary appeal of A2 Greek yogurt lies in its potential for easier digestion. Symptoms often associated with dairy sensitivity, such as bloating, gas, and stomach upset, are frequently attributed to lactose intolerance. However, some people may be reacting to the A1 beta-casein protein. By consuming A2 dairy, these individuals might experience a reduction in these gastrointestinal symptoms. A 2023 study from Purdue University suggested a difference in gastric emptying times between A1 and A2 milk, with A2 potentially being associated with less indigestion.
