Cow’s milk is a nourishing beverage that is naturally produced for humans and animals. Many people and animals widely recognize its off-white appearance. It is the most popular kind of milk consumed globally.
There is a distinct sentiment associated with milk in India.
India boasts the world’s largest dairy herd, comprising over 300+ million bovines and producing an impressive 180+ million tonnes of milk. Among all countries, India ranks first in both milk production and consumption.
Cow’s milk, in particular, has been what ancestral people constantly advised us to consume because they believe it could give us immunity against multiple diseases.
If you’ve ever wondered how cow’s milk boosts immunity, the following blog provides 10 scientifically supported explanations.
Cow’s milk nutrients
Cow’s milk is rich in nutrients like calcium, vitamin D, potassium, zinc, vitamin B12, vitamin A, and protein, making it a nutritional powerhouse. Research has demonstrated that cow’s milk contains the necessary micronutrients for immune functions—not just one, but multiple specific micronutrients.
Cow’s milk is high in tryptophan
We all love to drink milk at bedtime, but why? Ever wondered.
Tryptophan is an essential amino acid which is found in cow’s milk. In the body, tryptophan transforms into serotonin and melatonin.
Serotonin is a neurotransmitter that helps control mood, appetite, and sleep, whereas melatonin is a hormone that assists in regulating sleep. Sleep plays a crucial role in boosting immune functions.
The conversion of tryptophan into these compounds is influenced by several factors, including diet, genetics, and environmental factors, such as light exposure.
Insufficient tryptophan can cause health problems like depression, anxiety, and sleep disorders. Effect of milk-honey mixture on the sleep quality of coronary patients: A clinical trial study – PubMed (nih.gov)
Amino acid
Cow’s milk contains 9 essential amino acids. Studies have shown that eating a well-balanced diet high in vital nutrients serves to strengthen a strong immune system.
Cow’s milk is a complete protein source since it has all nine essential amino acids needed in the development and maintenance of immune cells.
Building blocks for the production of enzymes, antibodies, and other immune molecules are these amino acids. Research has shown a positive connection between amino acids and immune functions.
The connection between CLA and milk
Milk contains conjugated linoleic acid (CLA), a kind of omega-6 fatty acid that has immune-stimulating properties.
Studies have indicated that CLA has the ability to modulate immunological reactions and reduce inflammation, perhaps offering protection against infections and autoimmune conditions.

Contains prebiotics
Cow’s milk contains prebiotic, which our gut bacteria eat as a sort of food. Prebiotics support the development of these good bacteria, which is beneficial for immune function and a healthy gut microbiome.
Prebiotics are indigestible fibers that ferment and nourish beneficial bacteria in the stomach instead of being digested there.
Cow’s milk contains oligosaccharides, a common prebiotic that is good for infants. The oligosaccharide types that function as prebiotics are fructooligosaccharides and galactooligosaccharides.
Antibacterial and antimicrobial properties
Cow’s milk possesses antibacterial and antimicrobial qualities, it can either inhibit or eliminate germs and other pathogens.
Cow’s milk contains natural antibacterial properties because of the presence of lactoferrin, lactoferricin, and lactoferricin B. These compounds have been shown to inhibit the growth of various bacteria.
Lactoferrin (LF) is an iron-binding protein belonging to the transferrin family, discovered for the first time in cow milk in 1939.
Immunoglobulins
They’re called antibodies. There are three groups of immunoglobulins found in Milk.
- IgA, or immunoglobulin A, is the most prevalent immunoglobulin found in cow’s milk. Because it protects against respiratory and gastrointestinal tract infections, it is crucial for mucosal immunity. IgA can stay in the stomach and provide targeted defense since it is resistant to digestion.
- Compared to IgA, immunoglobulin G, or IgG, is found in lower concentrations. Enhances phagocytosis and eliminates pathogens to preserve systemic immunity. IgG remains unchanged after pasteurization.
- IgM, or immunoglobulin M is the immunoglobulin that is least common in milk. It participates in the early stages of the immune response, especially during acute infections.
Colostrum: The first milk given after calving contains a very high immunoglobulin concentration. It provides essential passive immunity to the newborn calf.
Glutathione
Glutathione, a potent antioxidant found in cow’s milk that eliminates free radicals and protects cells from oxidative damage, is essential for immune system support.
It is believed to help in preventing oxidative stress, which is linked to aging and a number of illnesses.
Additionally believed to have anti-inflammatory qualities, glutathione may aid in immune system maintenance.
It’s important to note that the amount of glutathione in cow’s milk can vary depending on the breed of the cow and the diet they are fed.
Contains growth factors
Cow’s milk has growth factors like insulin-like growth factor 1 (IGF-1). These growth factors help promote a strong immune system.
Growth hormone (GH) from the pituitary gland stimulates the liver to create IGF-1. Additionally, transforming growth factor-beta (TGF-beta), which is essential for tissue regeneration and repair, can also be obtained from cows.
Although the IGF-1 is naturally present in cow’s milk, some dairy firms inject rBGH hormone to boost dairy production.
Although IGF-1 is necessary for growth, elevated levels may raise the chance of developing certain illnesses.
To be on safer side buy the cow’s milk from an authentic place that does not use RBGH injection.
Selenium
Milk is a significant Se source, with 100g providing up to 10% of adults’ daily requirement. The bioavailability ensures that selenium is present in milk and can be consumed by humans.
Cellular antioxidant systems and human health greatly depend on selenium, an essential trace element.
Cow’s milk is a rich and easily absorbable source of selenium for humans. Research shows that the influence of selenium on the immune system is directly proportional.
There are more advantages to cow’s milk than just these ten. One of the panchamrit in Ayurveda is milk. However, there is now scientific proof that milk benefits the entire body, not only the immune system. It is a superfood since it is loaded with nutrients. A diet that includes milk may be advantageous for the person.
Including milk in diet could be beneficial for the individual If milk is not causing any problem.
