Other immune boosting supplements

Vitamin D

Vitamin D is a fat-soluble nutrient essential to the health and functioning of your immune system, helping to generate more white blood cells and reducing inflammation throughout the body. Vitamin D has also been linked with COVID-19. Research has shown that low levels of vitamin D are linked with more severe COVID symptoms and may even increase the longevity of the disease.

Vitamin C

Vitamin C supports the function of various immune cells and enhances their ability to protect against infection. It’s also necessary for cellular death, which helps keep your immune system healthy by clearing out old cells and replacing them with new ones.


Zinc is essential for multiple cellular functions including immunity. Zinc has been shown to protect the body from respiratory infections and even reduce the longevity of these illnesses.


Possible one of the more lesser known immune boosting supplements? Elderberry extract has been shown to enhance immune system response and may help shorten the duration and severity of colds as well as reduce symptoms related to viral infections.
