COVID-19 studies are our top priority. For all other studies, we recommend commencing the registration process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission as we are experiencing 4 week turn-around time in review of submissions and resubmissions. We currently do not have the capacity to expedite reviews.

Note also there are additional delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
The intervention is Palmitoylethanolamide (PEA) or Curcumin (2 arm study).

Participants will take 1 capsule containing 175 mg of PEA twice daily for 2 weeks (1 capsule in the morning and 1 capsule in the evening).


One capsule containing a total 500 mg of HydroCurc taken daily in the evening before bed for 2 weeks.

Compliance will be monitored via capsule return at the end of the study.

Treatment: Drugs
Comparator / control treatment
In this study there are two placebo comparator groups:
Placebo - PEA: The placebo product will be maltodextrin encapsulated in an opaque capsule. It will appear identical to the test products. It will be administered as two capsules using the same procedure detailed above for PEA.


Placebo - Curcumin: The placebo product will be maltodextrin encapsulated in an opaque capsule. It will appear identical to the test products. It will be administered as a single capsule using the same procedure detailed above for curcumin.

Compliance will be monitored via capsule return at the end of the study.

Brief summary
This is a double-blind, randomised, clinical study with a 14-day treatment duration with 2 arms (with 2 active ingredient groups and 2 placebo groups). The aim of this study is to assess the effectiveness of PEA and curcumin on reducing joint pain in otherwise healthy adults aged 25-70 years, compared to a placebo. A placebo is a substance with no therapeutic effect, in this case maltodextrin.

Participants will be asked to attend our clinic to complete their enrolment with a Trial Coordinator. During this visit, they will also complete an initial assessment including, letting the trial coordinator know about their joint pain and general health by completing questionnaires; height and weight measurements; and a blood test.
At the conclusion of the visit, participants will be randomly allocated to either the PEA, curcumin or placebo treatment group.

Once enrolled in the study, participants will be asked to complete 3 days of pain recording (once morning and once at night) online.
Following the completion of the 3 days of pain recording, trial coordinators will confirm supplementation commencement. Capsules should be consumed as described on the label.
Once supplementation has started, participants will be required to record their pain level every morning upon waking, and every night prior to going to bed for 2 weeks.
At the completion of the 2 weeks, participants will be required to attend the clinic for a final appointment where they will complete identical assessments to the initial visit.
