This study requires

If you decide to volunteer, you will be asked to participate in a screening visit. This will be held at the Ragle Human Nutrition Research Center (1283 Academic Surge) on UC Davis campus.

We will start the screening session by obtaining your consent to participate in the study. We will then measure your height, weight, waist circumference, blood pressure and heart rate 3 times, 5 minutes apart, after a 15-minute rest, and have you fill out a questionnaire on your health, diet, and medication and supplement use.

You will then be asked to donate a fasting blood sample (30 mL ~ 2 tablespoons). A retest blood sample may be requested by the study physician or if a blood sample is not able to be processed for analysis. If a retest is requested, you will be asked whether or not you are willing to submit another fasting blood sample, and you will be appropriately compensated for your time, which will be the same amount as for a screening visit.
