Study type
Interventional
Description of intervention(s) / exposure
This is a randomised double-blind placebo-controlled study with a 6-week participation and 2 groups (1 active ingredient group and 1 inactive placebo group). HydroCurc® is a TGA approved product (ARTG ID 295857) containing the active ingredient Curcumin.

Once enrolled in the study, participants will be randomly allocated to either the placebo group or the active treatment group. An opaque container of capsules will be provided to each participant according to their randomisation. Participants will be instructed to take 2 x 250 mg capsule of HydroCurc [(total containing 450 mg of a curcumin extract (containing 95% or 427 mg of curcuminoids)] daily with water and food for the duration of the study (6 weeks).

Participants will be asked to attend the study site at baseline, at 21 days (mid-point) and 6 weeks (final). At baseline, participants will complete a fasting blood test, general health measurements and health questionnaire. A fasting blood test and health questionnaire will be completed at the study site at 21 days and 6 weeks. At the end of the six weeks, participation in the study will be considered complete.

Adherence will be monitored by product return at completion of 6 weeks of supplementation
Intervention code [1] 319194 0
Treatment: Drugs
Comparator / control treatment
The placebo will be microcrystalline cellulose encapsulated in an opaque vegetable capsule. It will be produced to appear identical to the test product. The placebo will be administered as 2 capsules taken daily for the duration of the study (6 weeks) using the same procedure detailed for the Active product HydroCurc®. The placebo product is to be stored in identical trial product containers at room temperature away from direct sunlight.
