How Supplements Benefit the Immune System

The immune system defends the body from pathogens which cause disease. It is composed of innate responses, which are the first line of defense, and adaptive responses, which become engaged later. Taking the recommended amounts of specific vitamins and minerals can help maintain proper immune function. Vitamin A, vitamin D3, selenium, and zinc are a few of the supplements that can benefit the immune system. Keep reading to learn more. 

Vitamin C

Vitamin C rich fruits, vegetables and nuts

Vitamin C, which promotes the formation of healthy blood cells, is a vital vitamin and necessary antioxidant that supports immunological health.* In order to protect the body from oxidative stress, healthy levels of vitamin C support the production of healthy blood cells and antioxidant levels.* Vitamin C also works synergistically with other antioxidants to help protect cells from damage from free radicals.*

Vitamin D3

Vitamin D3 is a necessary vitamin for the health of bones, and may also help to stimulate an adequate immune response.* In order to promote the health of the immune system, vitamin D plays a role in the activation of the immune system's T lymphocytes, which are responsible for identifying and defending the body against harmful substances.*

Selenium is a trace mineral. In combination with the protection of cells from oxidative damage caused by free radicals, selenium may help provide an optimal immunological response.*  In addition to reducing inflammation, and increasing immunity, these antioxidants contribute to lowering oxidative stress in the body.* There have been studies demonstrating a link between higher levels of selenium in the blood and an increased immunologic response.*


Quercetin is a plant flavonoid that acts as a natural antioxidant to protect cells from oxidative stress.* Quercetin is known for its antioxidant activity in radical scavenging and anti-allergic properties characterized by stimulation of immune system, antiviral activity, inhibition of histamine release, decrease in pro-inflammatory cytokines, leukotrienes creation, and suppresses interleukin IL-4 production.
