The body's immune system has a defence role. It is activated when the body detects an abnormality such as the entry of a pathogen into the body. During changes of season or in the face of stress, the body is not always as resistant and the body's immune defences can weaken. During these periods it is beneficial to support the body. LACTOFERRINE contributes to the proper functioning of the immune system and helps to reduce fatigue thanks to vitamin C. This food supplement is rich in lactoferrin, a protein contained in the first milk of mammals.
