Was die Evidenz sagt
Überwiegend Mechanismus / Beobachtung
Die meisten Studien zu Glutathione sind mechanistisch oder beobachtend statt RCTs, die einen klinischen Effekt messen — betrachte die Ergebnisse als vorläufig.
Die meiste Evidenz stammt aus hochwertigen Meta-Analysen und randomisierten Studien, veröffentlicht 2011–2026 mit einer typischen Studiengröße von 194 Teilnehmenden.
Basierend auf 17 Studien · 2 Meta-Analysen · 10 RCTs · 1,267 Teilnehmende insgesamt

Such supplementation can be beneficial, and it is most effective when combined with a diet rich in sulfur-containing foods and other nutrients that support GSH synthesis.
Bradauskienė V et al. · Nutrients (2026)
Whether through diet or supplementation, ensuring adequate GSH levels can have profound benefits on longevity, immunity, and overall well-being.
There are many foods known to contain GSH, and there are also many GSH supplements available on the market, but precursor-based supplements and compounds that activate GSH synthesis pathways show stronger and more consistent increases in human GSH.
A diet rich in protein (for amino acids) and phytochemical-dense plants can support this, while targeted precursors (e.g., glycine, γ-glutamylcysteine) and Nrf2-activating foods or agents provide the most robust increases shown so far.

Our meta-analysis indicated significantly decreased activity of GPx in patients with depression compared with HC, while the levels of GSH and GR were not significantly different between the groups.
Because no studies, or an insufficient number of studies, have been conducted on GSSG, GST, GCL, and GS, meta-analyses were not performed for these metabolites and enzyme activities.
Our findings suggest that abnormal cycling of the GSH system, particularly decreased GPx activity, is involved in the pathophysiology of depression and may serve as a potential biomarker for this illness.
To elucidate the clinical significance of glutathione, future research should focus on conducting randomized controlled trials, developing standardized formulations, and performing long-term safety assessments.

A consistent correlation exists between reduced GSH levels and neuronal dysfunction.
Elevated GSH levels enhance cellular resistance to oxidative stress and reduce apoptotic signaling.
GSH plays a pivotal role in cutaneous aging and tissue repair through redox regulation, mitochondrial protection, and the modulation of inflammatory and extracellular matrix pathways.
However, due to the limited number of studies, further investigations is suggested in this regard.

Data were subjected to meta-analysis using a random effects model to examine the effect sizes of the pooled results.
Walnut consumption resulted in a significant increase in catalase activity (CAT) (WMD: 42.20; 95 % CI: 34.28, 50.11).
Walnut consumption did not affect other biomarkers of oxidative stress such as lipid peroxidation (LPO), reduced glutathione (GSH), oxidized glutathione (GSSG) and oxygen radical absorbance capacity (ORAC).
