Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The potential participants are screened by the medicial monitor for inclusion in the study. The eligible participants are enrolled by Investigator and provided with a "Numbered Container" that is identical to all other containers and contains the same information on the label, except for the NUMBER. The investigator is blinded to the product randomized with the numbered containers labelled prior to delivery to Investigational Site. Product allocated as participants are enrolled in sequential order (1-44).

Summary
Brief summary
1. This is a double-blind, randomised, placebo-controlled study to evaluate the efficacy of a vitamin, mineral and herbal formulation. The aim is to investigate if the formulation reduces cold & flu symptoms including symptom duration compared to placebo.
2. All participants are provided with the cold/flu treatment pack – which includes the product (active treatment or placebo), a daily symptom diary and a pre-prepared QML pathology form for Influenza antigen testing.
3. If a participant experiences 2 or 3 more cold/flu symptoms during the 6 month study period (according to the Wisconsin Upper Respiratory Symptom Survey), they need to a) start treatment, b) have the antigen test taken at a local QML pathology collection centre, c) record their symptom severity in the diary every day until symptoms resolved.

4. Within 2 weeks from the cold/flu resolving, the participant is asked to attend a final interview, returning the diary and unused product.

5. There will be regular communication with all participants during the study. Once the number of cold/flu episodes reaches the quota (49 per group), all participants will be informed that the study has been completed. Therefore, it is expected that not all participants will experience a cold/flu episode while enrolled in the study.
