Online Screening Form

If you are interested in participating in a study, please contact Molly (303-492-2485; or Candace (303-735-6410; 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. Some medications are okay for certain studies.

  • Inflammatory Suppression of Endothelial Function with Aging and Habitual Exercise. We know that inflammation and oxidative stress are related to insulin resistance and endothelial function. This study examines if blocking inflammation improves vascular function and insulin resistance in subjects with varying characteristics. If interested please contact Molly (303-492-2485;

  • Vitamin D Supplementation and Vascular Function. This is an intervention study to examine how vitamin D supplementation may improve vascular function in middle aged and older adults with vitamin D deficiency or insufficiency. The study will involve 12 weeks of taking vitamin D or placebo tablets and measuring vascular function before, during, and after this period. If you are interested in participating in this study contact Candace (303-735-6410;

  • Oral Nitrite Therapy to Treat Arterial Aging. This study will determine the effectiveness of sodium nitrite, a naturally occurring compound in the body, for improving the health and function of arteries in middle-aged and older adults. It involves taking sodium nitrite or placebo pills for 10 weeks with vascular function measures before, during, and after the intervention. If you are interested in participating in this study contact Candace (303-735-6410;

  • Effects of Trehalose on Arterial Aging and Insulin Resistance. Trehalose is a natural sugar found in many foods, including mushrooms and honey. We are interested in whether trehalose can preserve arterial and insulin function in older adults. Study participants will consume trehalose or placebo drinks for 12 weeks. Arterial and insulin function will be measured before and after the 12-week intervention. If you would like more information, please contact Molly (202-492-2485;

  • 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 contact Candace (303-735-6410;
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.
