The immune system is our biological surveillance and defense system. It is a very complex system and its function depends on the existence of many control loops that communicate with each other. The immune balance is decisively influenced by the skin, the intestines, the kidneys, the lungs, the psyche and the nervous system. Even small deficiencies in nutrients can have a negative effect on the balance of the immune system. Whether, how quickly and how successfully our immune system neutralizes and disposes of foreign pathogens depends on the activity of the defense system, especially that of the immune cells. By supporting the immune cells with suitable multi-vitamin mineral preparations, the immune system can be significantly strengthened.
