The Bitter Truth About A1 Milk: Why Women Should Choose A2 Desi Cow Milk for True Health

By Rubick Marketing · Nov 05, 2025 · 5 Minutes

The Milk We Drink May Not Be the Milk We Need

For generations, milk has been celebrated in India as complete food  -  a source of strength, purity, and nourishment.
But over time, industrialization and imported cattle breeds have changed what we drink.

Most of the milk available today comes from HF (Holstein Friesian) and Jersey cows, which produce A1 milk.
While it looks the same as traditional milk, science shows that A1 milk can cause digestive issues, hormonal problems, and chronic inflammation, especially in women.

At Organic Mandya, we believe milk should heal, not harm. And that’s why we promote the milk that nature originally designed for us  -  A2 Desi cow milk.

“All milk looks white  -  but not all milk is right.”

A1 vs. A2 Milk: What’s the Real Difference?

The main difference lies in a single protein  -  beta-casein.

  • A1 milk, produced by foreign breeds like HF and Jersey cows, contains A1 beta-casein, which breaks down into a harmful peptide called BCM-7 (Beta-Casomorphin-7) during digestion.

  • A2 milk, produced by native Indian breeds like Gir, Hallikar, Sahiwal, and Tharparkar, contains A2 beta-casein, which digests easily and supports the body naturally.

How A1 Milk Affects Women’s Health

Women are more sensitive to hormonal and digestive changes, and A1 milk directly affects both systems.

1. Digestive Discomfort and Inflammation

A1 milk releases BCM-7, which inflames the intestinal lining, leading to:

  • Bloating and abdominal pain

  • Constipation or irregular bowel movement

  • Intolerance to milk and dairy products

Regular intake of A1 milk can disturb the gut microbiome  -  the body’s core defense system.
A2 milk, on the other hand, soothes digestion and supports nutrient absorption.

2. Hormonal Imbalance

A1 milk can disrupt natural hormone regulation by mimicking estrogenic activity in the body.
Over time, this may lead to:

  • Irregular menstrual cycles

  • PCOS (Polycystic Ovary Syndrome)

  • Thyroid dysfunction and weight gain

“What we feed the body can change how our hormones speak.”

3. Inflammation and Autoimmune Disorders

Studies indicate that BCM-7 from A1 milk increases systemic inflammation, which can trigger or worsen:

  • Arthritis and joint pain

  • Autoimmune thyroid issues

  • Early symptoms of diabetes and metabolic imbalance

4. Skin and Reproductive Health Concerns

The hormonal changes caused by A1 milk often surface as:

  • Acne and oily skin

  • Hair fall due to stress and hormonal imbalance

  • Decreased fertility and irregular ovulation

The Science Behind A2 Milk

A2 milk is closer to the milk produced by humans and ancient Indian cows thousands of years ago.
It digests easily and nourishes deeply because it doesn’t produce toxic BCM-7.

Nutritional benefits of A2 milk:

  • High in calcium, omega-3 fats, and antioxidants

  • Boosts immunity and bone strength

  • Improves gut health and metabolism

  • Balances hormones naturally

The Impact Beyond Health: The Farming Connection

This difference between A1 and A2 milk is not only about health  -  it’s also about the future of Indian farming.

Imported breeds (HF, Jersey) that produce A1 milk demand:

  • Heavy water and feed resources

  • High maintenance costs

  • Antibiotics and hormone injections

In contrast, Desi cattle producing A2 milk are:

  • Hardy and naturally disease-resistant

  • Adapted to Indian climate

  • Excellent sources of organic fertilizer through dung and urine

  • Central to sustainable cattle farming and organic agriculture

FAQs

1. What is A1 milk, and why is it harmful?

A1 milk is produced mainly by HF and Jersey cows. It contains A1 beta-casein protein, which releases BCM-7, a toxic peptide that causes inflammation, hormonal imbalance, and digestive problems.

2. How is A2 milk different from A1 milk?

A2 milk, from Desi cows like Gir or Hallikar, contains A2 beta-casein that digests easily and does not produce harmful byproducts like BCM-7. It’s safer for digestion, hormones, and immunity.

3. Is A1 milk linked to women’s health problems?

Yes. Regular consumption of A1 milk has been linked to PCOS, thyroid imbalance, skin issues, and menstrual irregularities due to its hormonal and inflammatory effects.

4. Can lactose-intolerant individuals drink A2 milk?

In most cases, yes. Many people with lactose intolerance digest A2 milk comfortably, as its structure supports smoother digestion and less inflammation.
