🛡️ Immunity

Immunity is the body's defence against germs and viruses. A newborn baby cannot yet protect itself well. So nature helps it through its mother's milk.

Colostrum and breast milk contain antibodies — protective proteins that recognize germs. They also contain lactoferrin, which takes iron away from bacteria, and other protective substances. WHO says that the antibodies in breast milk help protect a baby from many common childhood illnesses. This protection matters especially for calves: they are born with no antibodies at all and get them only from colostrum.

In adults, milk does not directly “boost immunity”. The immune system needs a full, balanced diet. That includes vitamins — for example, A and C. Vitamin A is found in milk fat. Gut bacteria also affect the body's defences. Fermented milk products with live bacteria support this gut flora, but the benefit depends on the specific bacterium. Bold “for immunity” claims on packaging are usually not proven.
