Optygen Pilot Study Proves Positive

The purpose of this study was to determine the effects on highly trained distance runners of a commercial herbal-based supplement purported to improve endurance performance by increasing oxygen uptake, assisting recovery, and reducing lactic acid production. Though changes in performance variables (VO2 max, hemoglobin, serum ferritin and salivary cortisol) were similar between groups, time to onset of lactate threshold was nearly 42% greater in E=experimental vs C=control group. These findings suggest that although some performance variables were not directly affected, use of a commercial- herbal based supplement may have helped improve lactate threshold levels significantly. read more >>
