Can I buy a product that boosts my immunity?

There are several products on the market that claim to boost immunity. However, it is important to know that the effectiveness of many of these products is not always scientifically proven.

Vitamin C is known for its role in immune function. It is an antioxidant and helps in the production and function of white blood cells. Vitamin D is crucial for activating the immune response. Vitamin D deficiency has been linked to an increased risk of infections. Zinc is important for the normal development and function of cells involved in the immune response. A normal diet contains sufficient zinc and vitamins C and D so that supplements do not have an additional effect on immunity.

Probiotics are live microorganisms that are beneficial for intestinal health, which in turn can influence immune function. Some studies suggest that probiotics can reduce the incidence of respiratory infections, but this effect is only short-lived and not clinically relevant. Echinacea is often used to prevent or treat colds and other infections. Most results from methodologically sound studies show no significant effect.

A healthy lifestyle is especially crucial for a strong immune system. This includes a balanced diet, adequate sleep, regular exercise, and stress management.
