In another MRS study involving MCI subjects, it was found that GSH level increases with MCI compared to elderly control [ 34 ]. This increase in GSH level was explained as an early compensatory or neuroprotective response [ 34 ]. However, in the same study, the GSH peak was identified using PRESS pulse sequence in a 3T scanner where GSH peak appeared in close proximity of high intense choline peak.

The probable anomaly of these results is due to the use of a PRESS sequence for detection of GSH. With this technique the GSH signal will be partly overlapped by intense signals arising from choline and creatine, thus complicating the accurate measurement of GSH.

The MEGA-PRESS pulse sequence, on the other hand, is a very selective and confirmatory method to detect the GSH peaks. Hence, in any clinical trial involving GSH measurement, MRS with MEGA-PRESS should be the method of choice for AD clinical study with GSH [ 23 ].

There are various clinical trials involving GSH to investigate GSH transportation across the intestinal epithelium [ 35 ], therapeutic effects of oral administration of glutathione in patients with non-alcoholic fatty liver disease [ 36 ], effect of oral GSH supplementation on changes in erythrocyte GSH level [ 37, 38 ].

The effect of GSH on anti-aging features wrinkles in the skin was also investigated [ 39, 40 ]. It was reported that GSH can be transported across the intestinal epithelium in an orally administered GSH in animal model study and the initial uptake of GSH into cells is reported as a rapid process [ 35 ].

The ingested GSH has potent nutraceutical benefits for human health to improve oxidative stress and defense in human [ 35 ]. The therapeutic effects of oral administration of GSH in patients with non-alcoholic fatty liver disease in open label, single arm, multi-center trial [ 36 ] indicated a significant decrease in alanine aminotransferase level as well as triglycerides, non-esterified fatty acids, and ferritin levels [ 36 ].

To determine the effect of oral GSH supplementation on erythrocyte GSH concentrations, including total reduced GSH, oxidized glutathione GSSG , and their ratio in a randomized, double-blind, placebo-controlled clinical trial for 4 weeks on 40 healthy volunteers were conducted.

Changes in erythrocyte GSH concentrations, including total reduced GSH, oxidized glutathione GSSG , and GSH: GSSG ratios were monitored. No significant changes in GSH concentrations in erythrocyte were observed [ 37 ]. In a long-term study, the effect of oral GSH supplementation on body stores of GSH in healthy adults, randomized, double-blinded, placebo-controlled trial GSH supplement for 6 months on 54 adults was conducted.

GSH levels in blood increased after 1, 3, and 6 months versus baseline. Natural killer cytotoxicity increased twofold in the high-dose group versus placebo [ 38 ]. This clearly demonstrates that study duration for oral GSH supplementation plays an important role for study outcome.

It was observed that melanin indices decreased consistently at two sites. Both GSH and placebo were very well tolerated. Oral GSH administration resulted in lightening of skin color [ 40 ].

Oral GSH was administered for 12 weeks in 60 healthy volunteers, and skin features including melanin index, wrinkles, and other relevant biophysical properties were measured. Blood samples were collected for safety monitoring.

GSH showed a significant reduction in wrinkles compared with those taking placebo. A tendency toward increased skin elasticity was observed in GSH compared with placebo.

There were no serious adverse effects throughout the study [ 39 ]. The subjects were observed over a one-month washout period. All cohorts of this study, including placebo showed improvement during the intervention regime. However, as this study aimed at evaluating an appropriate trial design, conclusions regarding the superiority of GSH over placebo were not drawn [ 23 ].

To compare bioavailability, the effect on oxidative stress markers and the safety of a new sublingual form of GSH was studied with two commonly used dietary supplements: N-acetylcysteine NAC and oral GSH. In this randomized crossover study, sublingual GSH, oral GSH and NAC were administered for 3 weeks in 20 normal volunteers.

Bioavailability, antioxidant efficacy, tolerance, reduced thiols, vitamin E, lipid status and adverse effects were monitored [ 41 ]. Significant superiority of a new sublingual form of GSH compared to both oral GSH and NAC, were observed.

All the dosage forms were well tolerated and no adverse events were reported [ 41 ]. A nutraceutical formulation containing N-acetylcysteine among other compounds has shown some pro-cognitive benefits in AD and older adults, but the impact of NAC alone is less robust [ 42 ].

To date, all GSH trials conducted addressed the bioavailability, tolerance level, dose dependence, and duration of the oral supplementation. Therefore, there is an urgent need for the study on GSH supplementation involving MCI and AD patients.

Furthermore, MRS measurement of GSH in the hippocampus needs to be monitored on those participants at various time points. The neuropsychological battery of tests at various time points for cognitive profile evaluation should be part of the upcoming clinical study. Finally, the GSH level in the hippocampus region and its correlation with the cognitive score will be a great measure for the identification of the impact of GSH supplementation both for MCI and AD compared to participants treated with placebo.

Curr Pharm Design , — Ann N Y Acad Sci , 5— Furthermore, glutathione depletion may lead to abnormalities in methylation metabolism and mitochondrial function. The researchers found glutathione levels were higher in older adults compared to younger adults. They suggest that the upregulation of glutathione synthesis is a response to increased brain oxidative stress that occurs with normal aging.

In contrast, postmortem human studies and animal studies reveal that aging is accompanied by decreased glutathione status in both men and women. Upregulated oxidative stress, nutrient deficiencies, or increased environmental toxin burden may result in depleted glutathione status. In addition, a lack of nutrient cofactors e.

When endogenous glutathione status is depleted, supplementation may be beneficial. Human clinical trials have reported clinically relevant benefits of supplementing with glutathione or N-acetyl cysteine a glutathione precursor to replenish brain antioxidant defense homeostasis , specifically liposomal glutathione.

Glutathione is a vital antioxidant in the body that modulates the redox balance and oxidative stress. Therefore, glutathione may play an important role in healthy aging and overall brain health.

For many, glutathione supplementation is an attractive choice due to its minimal side effect profile and proven link to cognitive functioning in healthy people. Glutathione is a common physiological molecule with a number of essential roles. In humans, glutathione is used in many fundamental metabolic processes ranging from the nitric oxide cycle to dietary mineral incorporation. During cellular differentiation, glutathione triggers stem cells to change their characteristics and transform into the kind of cell the body needs.
