Our immune system consists of specialised organs, cells, and tissues that work together to combat the disease-causing viruses and bacteria that can enter our bodies. These elements operate as an integrated system and produce the immune cells that circulate in your body to detect and attack any foreign invaders. In order to develop and function properly, these immune cells need specific nutrients, with support from well-formulated supplements a potentially beneficial solution during periods of heightened demands, like during an infection or the flu season.
