Influence of Instaflex Advanced supplement on joint function:  a randomized, placebo-controlled community trial

LOCATION:  Human Performance Laboratory operated by Appalachian State University at the North Carolina Research Campus, Kannapolis, NC 28081   704-250-5352

What is the purpose of this research? Joint discomfort is reported by 32% of U.S. adults, and increases with age. The knee is the most common site of joint discomfort regardless of age. Nearly half of people with knee joint discomfort use natural supplements to alleviate symptoms, but more research is needed to determine their effectiveness.  The Instaflex Advanced supplement includes six natural products:  turmeric, resveratrol, Boswellia serrata, collagen, hyaluronic acid, and black pepper extract. This unique blend may relieve joint discomfort discomfort and increase mobility, but has not yet been tested in humans using a randomized, double-blinded, placebo-controlled research design.  The primary purpose of this study is to assess the effect of 12-weeks ingestion of the Instaflex Advanced supplement compared to placebo on knee function in adults with self-reported knee joint discomfort.

Why am I being invited to take part in this research? You will be one of 66 men and women, ages 50-75 years, in this study.  You are being invited to take part in this research if you have had knee joint discomfort (mild or greater) during at least the previous 3 months, and are willing to avoid the use of non-steroidal anti-inflammatory drugs (NSAIDs) use (e.g., ibuprofen, aspirin), and other pain supplements and medications during the entire 12-week study (and the 2-week period before the study begins).  Additionally, you cannot have a serious medical and mental problem that would interfere with study participation (e.g., current cancer case, severe rheumatoid arthritis, recent heart attack, recent stroke, congestive heart failure, ulcers, kidney disease).  You must also agree to keep your weight about the same during the 12-week study.

What will I be asked to do? The research procedures will be conducted at the Human Performance Laboratory (Room 1201, Plants for Human Health Institute Building, 600 Laureate Way), operated by Appalachian State University at the North Carolina Research Campus (NCRC) in Kannapolis, NC.  You will need to come here for orientation/baseline testing and then 3 other lab visits (each session will take about 30 minutes). The total amount of time you will be asked to volunteer for this study is about 2 hours at the Human Performance Laboratory (over a 12-week period).  You will also take a daily supplement for 12 weeks and keep compliant with this regimen.

Will I be paid for taking part in the research? We will pay you $300 for the time you volunteer while being in this study.

Tobacco Study

Study Purpose: This study will look at the effects of inhaled tobacco, from hookahs, vaping, and e-cigarettes.

Recruiting: Men and women ages 18-50 with no significant health problems, including asthma, chronic lung disease, cardiac disease, or any immune deficiencies. Woman who are pregnant should not participate

What You’ll Do: Visit the UNC NRI, in Kannapolis, NC, twice in a 6 week period. First visit for screening, second visit for blood draws and breathing test. Each visit lasts 1-3 hours. Eligible participants will be compensated $140. Additional $40 compensation to vapers, smokers, or hookah users completing a 4-week smoking diary.  Call 919-966-2879 or email for more information.

Fructose Study

Recruiting: African American, Hispanic and Caucasian participants
30 to 50 years old. Must be free of diabetes, fructose intolerance, and chronic kidney disease
What You’ll Do: Volunteers will come to the NRI (Kannapolis, NC) for approximately 3 hours, undergo an oral fructose challenge, fill out questionnaires, provide serial blood and urine samples
Study Purpose: High uric acid in the blood increases the risk of gout, kidney and heart disease. This study investigates whether each individual responds to sugar-sweetened beverages differently, due to their differing ethnicity and genetic backgrounds.
Eligible participants will be well-compensated once the study has been completed.
Get started today. Call 704-250-5060 or email

Fatty Liver Study

Study Purpose: To evaluate a new painless/non-invasive technique to study fatty liver disease.
Recruiting: 18 – 70 year olds with fatty liver disease.
What You’ll Do: Participants will volunteer for 2 days. Two non-invasive tests will be conducted to evaluate a known diagnosis of fatty liver disease. Each visit will take approximately 1 – 2 hours.
Eligible participants will receive $75 upon completion of each visit.

Maternal and Child Health Study  

The UNC Nutrition Research Institute seeks to determine the effect of pregnancy complications in African American mothers on the disease risk of their children. Examples of pregnancy complications include high blood sugar, high blood pressure and preeclampsia.


  • African American mothers
  • Must be 18 years or older
  • With two or more children between ages 5-10
  • Mothers may or may not have had pregnancy complications

Volunteers will stay 1 to 2 hours to fill out questionnaires and provide blood, saliva and urine samples. See Details


Duke-Kannapolis this fall will begin recruiting 850 participants for the MURDOCK COPD Study, a five-year observational study to better understand clinical outcomes in a community-based COPD cohort.

Study results will be used to determine if the current classification system that categorizes the severity of a patient’s COPD correlates with the clinical course of the disease in a real-world setting. Results could also help researchers understand how COPD therapies are applied in the community, as well as describe the clinical course of COPD in a community cohort.

The study’s principal investigator is Scott Palmer, MD, MHS, director of DCRI Pulmonary Research and a professor of medicine with the Duke Clinical Research Institute. The co-principal investigator is Jamie Todd, MD, assistant professor of medicine with the Duke Clinical Research Institute.
