The Impact of Qualia Gluthathione+ on Blood Glutathione Levels

This is a double-blind, placebo-controlled, parallel-group, triple-armed, study evaluating the effects of two distinct Qualia Glutathione+ formulations on Whole Blood Glutathione levels in the blood of healthy adults aged 45-75 years. Approximately 18 participants will be assigned to one of three study arms: Qualia Glutathione+ version 1, Qualia Glutathione+ version 2, or placebo. Each participant will take two or three capsules of their assigned product once daily in the morning, with or without food, over a 20-day period. The primary outcome is the change in blood glutathione levels, assessed via in lab blood collection at baseline and study completion. Secondary endpoints include questionnaires measuring health-related quality of life, fatigue, and cognitive functioning (PROMIS Global Health-10, PROMIS Short Form v1.0 - Fatigue 10a, PROMIS Cognitive Function - Short Form 8a), evaluation of safety and tolerability, and an Overall Experience Questionnaire (Appendices 1, 4-7). All assessments, including electronic questionnaires, are completed remotely without in-person visits.
