Vitamin C, Vitamin D, and Zinc: Where Immune Systems Get Their StrengthImportant for all life stages, including childhood10

Vitamin C helps support immune system defense by enhancing innate immune pathways. It also supports adaptive immunity through differentiation and proliferation of B- and T- lymphocytes.11 

Vitamin D assists immune function by serving as a regulator while promoting phagocytosis and superoxide synthesis.10 Low vitamin D status has been identified as a risk factor for compromised immune function and may contribute to the chances of a poor immune response to environmental challenges.12,13 

Zinc plays a role in immune responses, and adequate status helps the body during immune system challenges.14 It also assists in immune cell function.15-20 It’s especially important for children, where adequate status helps the body during immune system challenges.14
