Synergy
What is happening. Both target early-phase viral upper respiratory illness through distinct antiviral and immune-modulating mechanisms, supporting an additive symptom-duration benefit.
Mechanism. Zinc inhibits viral replication and supports T-cell function while elderberry flavonoids modulate cytokine release, giving complementary rather than competing effects on the immune response.
Recommendation. Reasonable to combine during the early days of a cold; take zinc with food if it causes nausea. No timing separation required.
