I didn’t realize vitamin D had immune system benefits. How exactly does vitamin D work to support my immune system health?

Researchers have found vitamin D receptors on most immune cells suggesting a significant role for vitamin D in the immune system. In fact, when we're not getting enough vitamin D, our immune system may not to function at its best. That’s why we recommend having your vitamin D level tested with your health care professional so that they can help you decide on the vitamin D product that is right for you.
