Most cow’s milk found in grocery stores contains two beta-casein proteins that are known as A1 and A2. But this wasn’t always the case. Back in the day, cows only produced the A2 protein. At some point along the way, a mutation occurred, and most of our milk-producing friends started to make the A1 protein as well.
Luckily, there are still cows out there that only produce the A2 protein. They are the ones that make A2 milk possible.
A2 milk protein is not a product of genetic engineering or modification. It’s naturally obtained from these special cows. And since all cows’ milk originally only contained the A2 protein (and no A1), we could say A2 milk is the OG of milk.
So what sets A1 and A2 apart? The distinction between the two proteins is subtle. They only differ in structure by one amino acid, but that tiny variance may have a big impact on the way the protein is digested. A theory suggests that milk that only contains A2 may be easier for our bodies to digest.
If you take a trip to the grocery store, there are so many milk choices in the dairy isle. Whole, fat-free, organic, soy – the options are endless! Today, we are more informed when it comes to meeting our specific food needs and we are constantly looking for alternatives to accommodate our lifestyles.
That’s where A2 milk comes into the mix. Regular cow’s milk contains both the A1 and A2 beta-casein proteins. However, the A1 protein may be hard for some people to digest, causing digestive discomfort and an unpleasant experience, similar to lactose intolerance. A2 milk comes from hand-picked, DNA-tested cows that only produce the A2 beta-casein protein.
It can be disheartening to see your little one upset or in discomfort. Symptoms of stomach discomfort associated with milk digestion could include gas and bloating. This type of digestive discomfort can often lead to a fussy, crying baby.
A2 milk may be naturally easy to digest for your little one’s tummy, as the A2 protein is similar to that found in breast milk. A2 milk is selectively sourced from cows who are fed a plant-based diet and are never treated with antibiotics or artificial growth hormones.
If your little one seems to be experiencing milk-related discomfort, consult with your doctor to see how your baby could benefit from A2 milk.
