Vitamin B6 is essential for the production of antibodies and the functioning of immune cells. It aids in the synthesis of neurotransmitters and hormones that regulate the immune system. A deficiency in vitamin B6 can impair immunity and increase susceptibility to infections.

Zinc is critical for the development and functioning of immune cells, including T-cells and macrophages. It has been shown to have a direct impact on the immune response, and adequate zinc levels are necessary for maintaining skin integrity, which serves as a barrier against pathogens.
