Choline Status Study

Study Purpose: The purpose of this study is to determine which biomarkers in the blood most accurately reflect choline status. Choline is an important nutrient in human diet.

What participants will do: To do this, volunteer subjects will be placed on a low choline diet for two weeks, followed by a two week washout, and then another two weeks on a diet containing adequate choline levels. We will provide all your meals for the 4 weeks (28 days) spent on the low choline and adequate choline diets, and you must not eat or drink any other foods during those weeks. We will take blood and urine samples at various times throughout the study to examine various markers and determine how they are changed by dietary choline levels.

Recruiting: Healthy males and females between ages of 17-70 years of age.
To participate your weight must be between 132-177 lbs.

Compensation: Eligible participants will be compensated for their time and payments will be reported to the IRS as income unless you choose to participate without compensation. The amount is $750 for completing the study

Influence of Purity Product Supplements on Muscular Strength, Serum Testosterone Levels, Sexual Function, and Quality of Life

Principal Investigator: David C. Nieman, Human Performance Laboratory at the North Carolina Research Campus, Appalachian State University, Health, Leisure, Exercise Science.

What is the purpose of this research?

Decreased muscle size, strength, serum testosterone levels, and sexual function are common with increase in age in men.  There is increasing interest in the use of supplements to help counter these changes, and this study will determine the efficacy of ingesting two natural supplements over a 6-week period in improving muscular strength, serum testosterone levels, sexual function, mood state, and quality of life in 120 men ages 40-70 years.

Why am I being invited to take part in this research? 

You will be one of 130 men, ages 40 to 70 years, in this study at the ASU-NCRC Human Performance Lab in Kannapolis, NC.  You are being invited to take part in this research if you are a healthy male that is not lifting weights more than once per week, and in a stable relationship during at least the past 3 months, with active sexual relations.   During the 6-week study (and for 2 weeks prior), you cannot be using Viagra, Cialis, or Levitra (or similar products), or supplements with ingredients advertised for their influence on muscle strength, sexual function, or testosterone.

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 just before the study begins, and then 2 other lab visits (at 3 and 6 weeks into the study).  Each session will take about 30-45 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 6-week period).  You will also take a daily supplement for 6 weeks and keep compliant with this regimen and all study requirements.  At each of the three morning visits (you can choose a time between 7:00 am and 9:00 am), you will come to the lab not having consumed food or beverages (other than water) for at least the previous 9 hours, and having abstained from vigorous exercise and sexual activity for at least the previous 24 hours.  Within three days prior to each lab visit, you will use Survey Monkey via the Internet to fill in responses to three questionnaires regarding quality of life, mood state, and sexual function. At the lab session, you will fill in a symptom log (for the previous 3-week period), have your blood drawn to analyze serum levels of free and total testosterone, and be tested for strength (hand grip, leg/lower back, YMCA bench press) and body composition.

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.

Project Baseline

Project Baseline is a long-term quest to map human health.  The Project Baseline study, launched in 2017, is the first initiative of Project Baseline and is a collaboration among teams at Verily, Duke University School of Medicine, Stanford Medicine, and Google.

Compensation: Offered throughout the study, which will follow participants for at least four years.

Interested in enrolling? To learn more and consider joining this exciting endeavor, visit or call 855-5-BASELINE (855-522-7354).

How long will the Project Baseline study last? How many people will enroll?

The Project Baseline study is an observational study that will collect, organize, and analyze broad health data from approximately 10,000 participants over the course of at least four years.

Who can participate in the Project Baseline study?

Participants must be at least 18 years old, residents of the United States, able to speak and read English or Spanish, and not severely allergic to nickel or metal jewelry.

What is the Project Baseline study trying to find out?

The study is designed to develop a well-defined reference, or “baseline,” of good health, as well as a rich data platform that may be used to better understand the transition from health to disease. Participants will join together with a team of experts from across academia, medicine, science, technology, engineering, and design to better understand how health can change over time. Participants will be asked to visit a study site up to four times yearly, test new technologies and wearable devices daily, and participate in interactive surveys and diaries by using a smartphone, computer, or call center. Data collected will include clinical, imaging, self-reported, physical, environmental, behavioral, sensor, molecular, genetic, and other health-related measurements. Biospecimens collected will include blood and saliva, among others.

The Duke Clinical and Translational Science Institute in Kannapolis announces a new study opportunity, the COPD Study. Chronic Obstructive Pulmonary Disease, or COPD, is a progressive disease that makes it hard to breathe. Smoking is the most common cause of COPD. If you have smoked, you might qualify. Researchers will study the severity of smoking-related symptoms in 850 people and follow the progression of lung function and symptoms over five years. Compensation will be offered throughout the study.

People who qualify for the COPD study:

  • Are at least 40 years old
  • May or may not have COPD or emphysema
  • Are current or former heavy smokers

The study will contact participants every six months for five years. To learn more, call 704-250-5861, email or visit
