Introduction: Why Immune Support Matters More After 40
As we age, our immune system becomes less efficient, making us more vulnerable to illness and slower to recover. But that doesn’t mean we’re powerless. For adults over 40 in the USA, focusing on natural immune support can lead to better health, fewer sick days, and greater vitality.

After 40, the immune system:
-
Produces fewer infection-fighting cells
-
Responds slower to threats
-
Becomes more prone to inflammation
This leads to longer colds, recurring infections, and even chronic fatigue. The solution? A proactive, whole-body wellness approach.
