The bottle will be clearly labelled as clinical trial medication with all necessary clinical trial information including contact details. Trial participation lasts for 84 days. Participants will be provided with sufficient MediHerb PhytoRegenex tablets at baseline (day 0) visit to last for 6 weeks, and an appointment will be made to visit on day 42. Study intervention use will be recorded, and any returned medication will be counted as a measure of compliance. At day 42 participants will be provided with sufficient MediHerb PhytoRegenex tablets at day 42 visit to last for 6 weeks, and an appointment will be made to visit on day 84. Study intervention use will be recorded, and any returned medication will be counted as a measure of compliance. Any participant with less than 60% compliance overall will be excluded from analysis. Follow up phone calls every 2 weeks (at week 2, 4, 8 and 10) will be used to monitor adherence. The last day of taking tablets will be on day 84, the day of the last visit. The last visit can occur (+/- 2) days depending on the availability of the participant.
