The proposed clinical trial will confirm the therapeutic absorption of glutathione following topical Glutaryl application in increasing blood GSH levels without an invasive procedure. GOAL: Confirm therapeutic level of glutathione following topical transdermal application. HYPOTHESIS: The hypothesis of the proposed study is that the glutathione administration will increase RBC levels of glutathione above 80%. AIM: Determine a non-invasive way to increase glutathione levels in the plasma and blood cells. This aim will be accomplished as follows: STEP 1: We will recruit eligible healthy participants in the two study groups who are not currently taking any glutathione or N-acetyl cysteine (NAC) supplementation. STEP 2: Determine baseline levels of GSH, free radicals and cytokines through analysis of venipuncture blood draws. STEP 3: Study subjects will be asked to spray themselves with either placebo or Glutaryl four times twice a day for three days on the ventral part of the abdomen. Measure the levels of GSH, free radicals and cytokines after 1 hour, 4 hour and 72 hours.

GSH
Levels of total, reduced, and oxidized forms of GSH in the isolated plasma, red blood cells (RBCs) and peripheral blood mononuclear cells (PBMCs) isolated from the peripheral blood of the two-study groups will be assayed by spectrophotometry using an assay kit from Arbor Assays (3-12).
Time frame: 72 hours
Free Radicals
To demonstrate that increased levels of GSH in the experimental group is accompanied by decreased levels of reactive oxygen species (ROS), free radical activity will be measured by malondialdehyde (MDA) assay that measures several end products of lipid peroxidation (3-12).
Time frame: 72 hours
Pro- and Anti-inflammatory Cytokines
To demonstrate that increased levels of GSH in the experimental group is accompanied by altered levels of pro- and anti-inflammatory cytokines and chemokines, we will measure the levels of pro- and anti-inflammatory cytokines and cytokines in the plasma derived from the two study groups by ELISA using an assay kit from ThermoFisher.
Time frame: 72 hours
