Boost your immune system for the cold season

The immune system is arguably the most sophisticated part of the human body, outside of the brain. (1) All through the year it is exposed to many foregn invaders daily, and when the winter comes the system gets increasingly exposed. 

As the immune system is your first and last defense against invaders, it is a good idea to put in an extra effort to ready it for the cold season. 

If your immune response is well-prepared, you will be less likely to be infected by the invaders that you encounter daily. Discover how to help maintain this important protective body system.

The two-pronged cold season strategy

A two-pronged immune system strategy can make you well-prepared for the cold season. 

Step 1 is a preventive step, where you fortify your immune defenses. Step 2 is a reactive step, where you take additional supplementation to help knock down the invaders before they can take hold.


Vitamin C is great when it comes to fortifying and preparing your immune system. It helps to activate both immune cells that can consume and destroy invading organisms and cells that recruit, organize and direct other immune cells.

Vitamin D helps to dismiss an invasion by readying the body’s innate immune system. The innate immune system is the body’s first line of immune defense, responsible for generating the initial reaction to health threats. (1) This is the part of the system which deals with “emergency responses”.

Scientists report that the strength of your immune system—at least 70% of which is located in your gut—relies on the makeup of your intestinal bacteria. (2,3)

Probiotics can restore your body’s natural, intestine-based protection against a host of non-intestinal diseases and shield you from the diseases of aging. (4-10)

Over time, an imbalance in the ratio of good-to-bad bacteria activates these many detectors in negative ways that can trigger the development of a host of diseases in many areas of the body—not just those associated with the gut.

Fortunately, probiotic supplements can restore a healthy balance to gut bacteria and reverse these disruptions to intestine-based signaling mechanisms. This, in turn, reverses the negative influence that triggers the development of chronic disease. (11)

Should certain microbes slip undetected past your immune system anyways, it’s important to be ready with a proper “emergency response”.

For instance, zinc ions released from a special zinc compound can attach themselves to the same cell receptors in the sinuses and throat that certain types of common cold viruses use.

This helps to prevent them from getting a foothold in the body and helps knock down an invasion in its tracks.

Some plants naturally have antimicrobal properties. One such is garlic, which is known for its support for healthy immune function.
