Immune-support pairing.

Zinc and vitamin C support different parts of the immune system, zinc by helping immune cells develop and hampering viral replication, vitamin C by supporting barrier and white-cell function, which is why they are bundled in so many cold-and-immune formulas.

What to do

Safe and sensible to take together, especially at the first sign of a cold. Take zinc with food to avoid nausea, keep it under about 40 mg a day and short-term, and do not expect either to prevent colds outright, since the effect is modest.
