Common Cold
Supplements studied for common cold.
Overview
Common cold research here centers on Echinacea, Vitamin C, Zinc, Vitamin D, and Eleuthero-containing Kan Jang. Echinacea may modestly reduce cold incidence and duration in some trials, though product and regimen differences limit consistency.
High-dose Vitamin C may slightly shorten symptom severity and duration but does not reliably prevent infection. Zinc and Vitamin D are marked possibly effective in this database with multiple indexed trials. Kan Jang (eleuthero plus andrographis) started early may relieve symptoms within days in studied formulations. See the heatmap and evidence reviews below for product-specific outcomes.
