Online Screening Form

If you are interested in participating in a study, please contact a researcher at 303-735-6410; ipalab@colorado.edu or 303-492-2485; cvstudy@colorado.edu. In addition, you can fill out our online screening form, which consists of questions that help us determine whether or not you qualify for a study. Each study is different and has different requirements for qualification. The research projects listed on this page are in various phases of recruitment. While projects may be ending recruitment, others may be just getting started, so if you are interested in research but don't qualify for a study at this time, please keep checking back.
  • Clicking on the link will take you to a website where you can answer the questions on the screening form (Online Screening Form). It is a secure website, and it should take about 10 minutes to fill out.

Research Initiatives

Ideal volunteers for the following research initiatives are healthy adults who are free of cardiovascular disease and other chronic health problems. Most medications are okay for the studies.


  • Oral Nitrite Therapy for Improving Physiological Functions in Older Adults. This study will determine the effectiveness of sodium nitrite, a naturally occurring compound found in the body and also green leafy vegetables, for improving body functions, including blood vessel, physical and brain functions in older adults. It involves taking sodium nitrite or placebo pills for 12 weeks with vascular function measures before, during, and after the intervention. If you are interested in participating in this study, please call 303-735-6410 or email IPAlab@colorado.edu.

  • Nicotinamide-Riboside Supplementation for Improving Physiological Function in Middle-Aged and Older Adults. This study will determine whether Nicotinamide Riboside (NR), a naturally occurring compound that is similar to vitamin B3 and found in milk, yeast, and other food products, improves body functions including blood vessel, physical and brain functions in older adults. Study participants will take both NR and placebo supplements for 6 weeks each in a randomly determined order. Measurements will be made at the end of each intervention period. If you are interested in participating in this study, please call 303-735-4799 or email cvstudy@colorado.edu.

  • Effects of Curcumin Supplementation on Arterial Aging. Curcumin is the active ingredient in the Indian spice turmeric, giving it its yellowish color. We are interested in whether curcumin can improve the health and function of arteries in middle-aged and older adults. To test this, study participants will consume curcumin or placebo capsules for 12 weeks with vascular function measures before and after the 12-week intervention. If you are interested in participating in this study, please call 303-735-6410 or email IPAlab@colorado.edu.
Qualified participants receive:
  • Free medical screening and diagnostic testing (bone scans, exercise stress tests, ultrasound, blood tests) completed by professional medical personnel.
  • Financial compensation for your participation.
Helpful and/or important information about our research:
  • All studies have passed rigorous examination by the University Ethical Research Review Board and are supported by the National Institutes of Health.
  • Studies take place at the Clinical Translational Research Center, which is located on the third floor of the Wardenburg Health Center on the CU-Boulder campus. A few sessions may take place at the Center for Innovation and Creativity located on the east CU-Boulder campus.
  • In general, visits take place in the morning, beginning between 7:00 am and 11:00 am Monday through Friday.
