Bio-availability Studies - get paid to relax with us!
Check your eligibility here


You may have seen many advertisements for clinical trials in Brisbane, but RDC is different. Our research is conducted on natural health products (not pharmaceuticals), and none of our studies require you to stay overnight in our clinic. 

As part of ongoing research into natural health products, studies are conducted to assess how quickly and effectively certain vitamins, nutrients, and herbal extracts enter and leave the bloodstream in healthy individuals.

As such, we are seeking participants for a series of bio-availability studies that will be conducted throughout the next few months.

Trial Outline

Participants will be required to attend our Newstead Clinic (Brisbane) to provide blood samples during the day. Depending on the study, the time spent in our clinic can range between 5 to 13 hours. All studies will then require you return for a single sample the following morning which takes approximately 5-10 minutes. None of our studies require any overnight stays! You will return home to sleep in your own bed at the end of the first day and then return the next morning for your single blood sample. 

Food and use of fast internet will be supplied during the required hours. We also have a range of jigsaw puzzles and Lego.

Participants are paid between $100 and $250 for each study. The amount paid is dependent upon the time requirements for each study.

Participants will be provided with the trial product to be taken upon arrival (after registration). You will then receive a cannula, from which the small blood samples (usually 5-10ml) are taken during the day. This is so multiple ‘needle pricks’ are not required, and participants are as comfortable as possible during the day.

Trials are conducted on readily available vitamins and nutrients such as vitamin C, CoQ10, ginkgo, resveratrol and fish oil, and will be taken within safe dosage ranges.

Members of the same household are welcome and may sit together during the day. Most participants bring a personal device (tablet, laptop) and either work, study, play games or binge-watch favourite shows. We do require that headphones are worn so other participants are not disrupted.

We will supply breakfast, lunch and dinner (if required), as well as snacks during the day.

Who can participate?
  • Men and women aged over 18 – 65 (please note that the most of our bio-availability studies have an age range up to 45)
  • BMI between 20-30
  • Non-smokers
  • Otherwise healthy (no serious or uncontrolled illnesses)
  • Not currently taking prescription anti-depressant medication

Please note that participants in our bio-availability studies will be provided with specific food and drinks whilst at our clinic. This is so that everyone participating in the study has similar food intake. Please note that these foods include dairy & gluten.

Our clinic is located on Level 3, 252 Saint Pauls Tce, Fortitude Valley (Brisbane).

We are easily be reached by public transport, but please keep in mind that our studies often start early (around 6.30am-7am), so best suited to those that live locally or early risers!
