How and when do I use it?

  • For the management of common cold symptoms, the recommended protocol of usage is: 5 day duration, started as soon as possible (preferably within 24 hours) after onset of infective symptoms suggestive of a common cold.
    • A common cold is a clinical syndrome of mild upper respiratory tract infection that can be caused by a number of viruses.5
  • Evidence for the most appropriate dosage is unclear, but the best support is for zinc acetate at a dose of 75mg/day or greater (of elemental zinc).1,6 There is no evidence of greater efficacy for doses over 100mg/day of zinc, therefore a dose of 75-100mg/day of elemental zinc is recommended.
  • It must also be noted that the use of zinc is only indicated for the treatment of common cold viruses, not other infections such as bacterial respiratory tract infections or more sinister viral infections such as influenza or COVID-19. Careful consideration should be given to ensuring more sinister infections are excluded (either clinically or with specific testing), noting that the symptom severity of COVID-19 symptoms can vary widely and may be misinterpreted as the common cold by some people
