Tag: A1 vs a2 milk

An estimated 70-75% of the world's population is lactose-deficient, making dairy difficult to process. When considering which milk is harder to digest, the answer is complex and depends largely on individual sensitivities to lactose, protein type, and fat content.

Milk protein consists of different variants, primarily A1 and A2 beta-casein, a distinction stemming from a naturally occurring genetic mutation in dairy cattle. What is special about A2A2 milk is that it comes exclusively from cows producing only the older, A2 beta-casein protein, which some people find easier to digest.

In October 2019, The a2 Milk Company discontinued its products in the UK, leading many to believe that A2 milk was no longer available. However, a growing number of independent, raw milk producers and online farm shops now offer A2 milk across the country, making it still possible to find for those who prefer it.

Casein makes up approximately 80% of the total protein content in cow's milk. While often discussed simply as 'casein protein,' this family of proteins has different genetic variants, most notably A1 and A2, which can impact how milk is digested and tolerated by some people.

While regular milk contains both A1 and A2 beta-casein proteins, a genetic mutation in some cows means A2 milk is naturally free of the A1 variant. This key difference leads many to question: is A2 milk better for your health?

Historically, all cow's milk contained only the A2 beta-casein protein, but a genetic mutation led to the widespread A1 variant found in most modern dairy. Today, A2 raw milk is gaining recognition for its superior digestibility and richer nutritional profile, making it a compelling choice for many.

An estimated 68% of the world's population has lactose malabsorption, but many who experience symptoms in the US report no issues when consuming dairy in Europe. This puzzling phenomenon is not a myth; it is rooted in key differences between the American and European dairy industries, along with variations in dietary habits and product processing.

Studies show that while A1 and A2 milk share the same core nutritional profile, their protein structure differs, which influences how they are digested. This distinction is at the heart of the ongoing debate about which milk is truly healthier for consumers.

According to scientific evidence, the beta-casein protein found in cow's milk exists in two main forms: A1 and A2, and this single difference can impact digestion for some individuals. This structural variation prompts many to ask: is A2 protein good for you, especially concerning gut health?

According to a 2019 review of studies, some individuals who experience digestive discomfort after drinking regular milk may find relief with A2 milk, which contains a different type of beta-casein protein. This article explores whether is A2 milk good quality and examines the scientific evidence behind its purported benefits.
