Vitamin D crucial to activating immune defenses (2010)
"Scientists have found that vitamin D is crucial to activating our immune defenses and that without sufficient intake of the vitamin - the killer cells of the immune system T cells will not be able to react to and fight off serious infections in the body. The research team found that T cells first search for vitamin D in order to activate and if they cannot find enough of it will not complete the activation process."
