- Brief Summary
This study seeks to determine the short-term effects of daily oral supplementation with a new micellar Glutathione formulation (LipoMicel) on the oral absorption and safety of glutathione in healthy volunteers.
The primary objective of this study is to evaluate and compare the pharmacokinetics of a novel micellar Glutathione (GSH) formulation with that of a standard formulation as well as a liposomal GSH formulation. The secondary objective is to evaluate the safety of a new micellar GSH formulation with higher bioavailability in human participants over a 30-day study period.

Group Intervention Description Liposomal Glutathione Liposomal Glutathione Each participant receives their treatment i.e., Liposomal Glutathione hard gel capsules at a total dose of 500 mg glutathione. Treatments are consumed with a glass of water (approx. 125mL), followed by a standardized breakfast (diet-controlled condition). Capillary whole blood samples are collected at different time points up to 24 hours post-dose. A washout period of at least 14 days between each treatment is used. Standard Glutathione Standard Glutathione Each participant receives their treatment i.e., Standard Glutathione hard gel capsules at a total dose of 500 mg glutathione. Treatments are consumed with a glass of water (approx. 125mL), followed by a standardized breakfast (diet-controlled condition). Capillary whole blood samples are collected at different time points up to 24 hours post-dose. A washout period of at least 14 days between each treatment is used. New Micellar Glutathione (Lipomicel) New Micellar Glutathione (Lipomicel) Each participant receives their treatment i.e., LipoMicel Glutathione soft gel capsules at a total dose of 600 mg glutathione. Treatments are consumed with a glass of water (approx. 125mL), followed by a standardized breakfast (diet-controlled condition). Capillary whole blood samples are collected at different time points up to 24 hours post-dose. A washout period of at least 14 days between each treatment is used.
- Primary Outcome Measures
Name Time Method AUC: the area under the concentration-time curve 0 (baseline; pre-dose), 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 12, 24 hours (post-dose) To determine the gastrointestinal absorption of orally ingested glutathione in healthy adult volunteers and compare the Area under the plasma concentration versus time curve (AUC) with that of other capsules containing glutathione.
Tmax: the time point of maximum plasma concentration 0 (baseline; pre-dose), 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 12, 24 hours (post-dose) To determine the gastrointestinal absorption of orally ingested glutathione in healthy adult volunteers and compare the time point of maximum plasma concentration (Tmax) with that of other capsules containing glutathione.
Cmax: maximum plasma concentration 0 (baseline; pre-dose), 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 12, 24 hours (post-dose) To determine the gastrointestinal absorption of orally ingested glutathione in healthy adult volunteers and compare the peak plasma concentration (Cmax) with that of other capsules containing glutathione.
