The A2 Milk of the cow is one of the best sources of protein as well as calcium and other nutrients such as fat, lactose, and other minerals. The crucial nutrients of the Milk are healthier for both adults as well as kids. So, having 8-ounces of milk every day helps you consume nine essential nutrients, including high-quality protein of around 8 grams. However, adding this simple beverage in your meal increases the nutritional value which comprises of:

  • Nutrients for bone-building like phosphorous, Vitamin D and calcium.
  • Vitamin B for the energy
  • Potassium, this nutrient assists in regulating the fluids in the body
  • Protein assists in building and maintaining lean muscle.
  • Vitamin A that helps in making the immune system healthy

Nutrients in Milk

The other nine essential nutrients of Milk help kinds as well as teens to develop a healthy and robust body. Consuming 8-ounce of Milk provides the following:

  • Potassium
  • Protein
  • Riboflavin
  • Calcium
  • Vitamin B-12
  • Vitamin A
  • Phosphorous
  • Niacin
  • Vitamin D

Cow’s Milk is the most consumed Milk all over the world and also healthier for both kids and adults. Usually, there are two types of cow milk, i.e. A1 milk and A2 Milk.

Ever heard about A1 and A2 Milk produces by cows? What kind of Milk it is and which type of cows produces A1and A2 milk? What is the specialty about A1 and A2 Milk, what are their benefits, and what is the difference among A1 Milk and A2 Milk?

Read the whole blog post and find out everything about A1 Milk and A2 Milk.

The A1 Milk derived by the cows of foreign breeds such as Holstein and Jersey. A2 Milk derived by the Desi or ancient breed cows such as Gir, Rathi, Sahiwal, Red Sindhi, and others. The protein available in the Milk of cows is of two types of whey protein and casein protein. The casein protein again categorized into two kinds i.e. alpha casein and beta-casein protein. 80% OF casein protein is available in the Milk.

Thus, beta-casein protein is of two types A1 beta-casein and A2 beta-casein protein. A1 beta-casein is available in cows that produce A1 Milk and A2 beta-casein protein available in the cows that produce A2 Milk.

Presently, A1 Milk is highly consumed Milk than A2 Milk all over the world. In East African countries, A2 Milk is available at different stores. In A2 Milk with the presence of A2 beta-casein protein, there is also a special kind of acid, which is known as proline. This proline available in the Milk converted into Peptides. Further, this peptide changed to an amino acid.

A1 milk-producing cows are found in India as well as foreign countries. Cows that produce A1milk are also known as hybrid cows. In A1 Milk there is a protein available known as histidine.

Why consider A2 milk?

A1 beta-casein, as well as A2 beta-casein proteins, is the same in function but they differ in digestion. Whenever A1 beta-casein protein reaches the intestine, and digestive enzymes break protein apart and releases an amino acid peptide chain called beta casomorphin 7 (BCM-7). Moreover, this chain of the peptide doesn’t release at the time of digestion of A2 beta-casein protein.

The amino acid present in A1 Milk and A2 Milk plays a more significant role. The proline available in A2 prevents BCM-7 to enter in the body.  BCM-7 is an opioid peptide that is not easily digested by the body.

BCM-7 can cause indigestion, and also it causes several diseases or other issues in the body such as diabetes or others. The BCM-7 protein is not available in the intestine, urine, and blood of the cows that produce desi cow milk. This BCM-7 protein present in the cow that produces A1 Milk. It is the reason digesting A1 Milk is not easy as compared to A2 Milk.

BCM-7 protein is highly harmful to the bodies of humans, and some of the research shows that digesting A2 Milk is much comfortable.

So, as per the research of the US National Library of Medicine National Institute of Health shows that A1 beta-casein protein contains a high amount of BCM-7 protein. If kids consume A1 Milk, then there are high chances that they can experience heart disease or diabetes. But. according to some Russian research, BCM-7 protein passes from the brain of the kids and stops kids’ bodies from developing. However, this study published in the International Journal “peptides”.

According to the research of the Indian Journal of Endocrinology and Metabolism 2012, Type-1 diabetes has a deep connection with A1 Milk. Also, A1 Milk can cause mental disorders, heart disease, autism, allergy and schizophrenia as BCM-7 passes from the blood to the brain.

According to some other research, it has been seen that consuming A1 Milk is harmful to health. But A2 Milk is the best drink to consume after consumption of the Mother’s Milk. Also, consumption of A1 Milk can cause type-1 diabetes, and A2 can cure this kind of diabetes. Thus, the individuals who used to consume A1 Milk daily can suffer from digestion issues, and A2 Milk is easy to digest. 

Meanwhile, most of the individuals who analyze themselves as lactose intolerant are reacting with A1 protein as being different from milk sugar. Thus, as a result, most of the clinical studies who have compared A1 and A2 Milk have reported that lactose intolerance caused when the individuals drink A1 Milk, but A2 Milk is safe as compared with A1.

Why is A2 milk better?

The foreign cow milk comprises A1 beta-casein protein which is broken down due to BCM-7 in the stomach. BCM-7 has several unpleasant effects on the health of humans.

Some Claims about A1 Milk

Type 1 Diabetes

This kind of diabetes is accessible in the kids and caused due to a lack of insulin. Various studies have shown that drinking A1 Milk in childhood can raise the chance of type-1 diabetes.

Well, these studies are just an observation. Still, there is not any kind of proof that A1 beta-casein protein can cause Type-1 diabetes. Only the individuals who are consuming A1 Milk are at higher risk of creating it.

There are some other animal studies too in which it is seen that there is not any dissimilarity among A1 and A2 beta-casein protein, but others show that consumption of A1 beta-casein can cause type-1 diabetes.

Heart Disease

There are two observational studies that show that drinking A1 milk can increases the chance of heart disease.

One of the tests on rabbits shows that A1 beta-casein protein encourages the fat buildup in blood vessels. On the other hand, this buildup fat was less when rabbits intake A2 beta-casein protein.

Thus, this fat gathered can result in clogging of blood vessels and causes heart disease.

Sudden Infant death Syndrome

It is one of the most common causes of death of infants who are under 12 months of age. However, sudden Infant Death Syndrome (SIDS) is the unexpected death of an infant without any apparent cause.

Some of the research has shown that BCM-7 has been the cause of SIDS in some cases.

Meanwhile, one recent study shows that high-level BCM-7 in the blood of infants temporarily stops breathing at sleep time.  This condition is called sleep apnea results in an increased risk of SIDS.

These all the results show that some of the children are sensitive to A1 beta-casein available in the Milk of cow. Before reaching any of the conclusions, further studies need to be done. 


It is a mental condition that is determined by repetitive behavior and reduced social interaction. As per the theory, peptides such as BCM-7 play a vital role in the progress of autism. Still, studies do not hold up every planned mechanics.

Still, there are not any human trials that have proved the effects of A1 Milk and A2 Milk on symptoms of autism.

Digestive Health

The inability to digest milk sugar entirely is lactose intolerant. Well, this is a common cause for diarrhea, gas and bloating.

Likewise. amount of lactose in A1 Milk and A2 Milk is ultimately the same. But still, it is seen that individuals are consuming A2 milk cause less bloating as compared to A1 Milk.

Studies indicate that the components of Milk other than lactose might cause digestive discomfort.

Moreover, some scientists have advised that A1 milk protein is highly responsible for some individual’s milk intolerance. However, it is identified that A2 Milk can be drunk by lactose-intolerant individuals.

Benefits Associated with A2 Milk

  • Availability of Omega-6 fatty acid
  • Highly nutritious for children
  • Improves digestive system
  • Keeps heart, brain, and body healthy
  • Assist in weight maintenance
  • Maintain the level of cholesterol
  • A2 Milk is an alternative Milk for infants
  • Raises immune power of humans body

Bottom Line

Now you might have completely understood the difference between A1 Milk and A2 Milk. A2 Milk is highly nutritious, and it contains A2 beta-casein proteins, which means that it is especially useful for hypertension as well as diabetic patients.  Identically. it is seen that individuals who are consuming desi cow milk have a lower risk of cardiovascular disease or Type-1 diabetes. Also, A2 Milk is perfect for individuals who have some physical symptoms such as ear infections or rashes.

Well, there is not any evidence that A1 Milk not good for health, but still it has been seen that A2 Milk is healthier than A1 Milk. But if you are struggling with digestion issues then, trying A2 Milk is worth it. Buy desi cow milk from DesiMoo which offers pure and natural milk at your doorstep.
