You know the feeling. Monday morning, busy week ahead, and then you feel it: that tickle in your throat, those heavy eyes, that fatigue no amount of coffee can fix. Your immune system is letting you down - exactly when you need it most.

In this article, discover which supplements actually work, what the science says, and where to find them cheapest at Belgian pharmacies.

How does your immune system work?

Your immune system is a network of cells, tissues and organs working 24/7 to identify and neutralize invaders. It consists of innate immunity (first line of defense) and acquired immunity (your body's memory).
