2.3. Laboratory Test Visits

Subjects reported to the lab in the morning hours following an overnight fast (no food or calorie containing beverages after 10 pm). They reported on three separate occasions, over an eight-week period: baseline, after four weeks, and after eight weeks of supplementation. Each test visit lasted approximately 45 min. At each visit, subjects arrived at the lab, rested quietly for 10 min and then had a blood sample taken. Subjects also turned in their diet logs, completed during the five days prior to each test visit (described below). Subjects completed three quality of life/subjective feeling questionnaires, as indicated below.
