The Last Word: Can You Actually ‘Boost’ Your Immune System?

The immune system is a network of cells, tissues, and organs that help your body fight infections, illnesses, and diseases. It works to recognize and protect against these foreign invaders that can make you sick.

When your immune system is functioning properly, it’s able to stop or fight off germs or foreign cells that can cause you harm, according to the Cleveland Clinic. So, it makes sense to want to know how to keep your immune system at peak function.

But is there anything you can do to boost your immune system, or is boosting the immune system just a concept created to market wellness products such as packaged foods, drinks, and supplements?

The Claim About Boosting Your Immune System

You’ve probably seen ads for things like supplements that claim the ingredients will boost your immune system. And in an atmosphere where we’ve seen multiple respiratory viruses (think COVID-19, RSV, and the flu) spreading at once, it can be tempting to buy into those types of claims — especially if the promise is you won’t get sick or you’ll recover from illness faster.
