L-Glutathione and Selenium: what the published research says
PubMed indexes 8 records that name L-Glutathione and Selenium together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to L-Glutathione and Selenium. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.
A study appearing here is not proof that an interaction exists. Two substances can be named together in a paper that never tested them in combination, and a source listed as background may cover only one of them.
Findings are quoted from each abstract as the authors wrote them. NutriStack has not re-analysed, pooled, or reconciled them, and they may disagree with each other.
NutriStack’s own interaction assessment for this pair is not published here. It has not completed qualified-human clinical review, so it is withheld from search. See the publication gate.
Nothing here is medical advice. Decisions about prescription medication and supplements belong with your prescriber or pharmacist, who can see your full regimen.
The research
8 studies naming L-Glutathione and Selenium.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
“Tissues particularly sensitive to changes in selenium supply include red blood cells, kidney and muscle. The meta-analysis identified that for animal species selenium-enriched foods were more effective than selenomethionine at increasing GPx activity.”
Names both L-Glutathione and Selenium in its title.
Journal of trace elements in medicine and biology : organ of the Society for Minerals and Trace Elements (GMS) · 1995 · PMID 8825978
Comparative StudyReviewHuman subjects
“Saturation of platelet GSH-Px activity occurred at lower plasma Se levels when selenite or selenate were used as Se supplements than with the organic forms. Interpretation of some of the results is provided and ideas are suggested for consideration in further studies.”
Names both L-Glutathione and Selenium in its title.
“These interactions can, however, be modified by increasing the amount of selenium in the feed. Among RA patients there is no clear evidence of an interaction between gold, selenium and GSH-Px.(ABSTRACT TRUNCATED AT 400 WORDS)”
Names both L-Glutathione and Selenium in its title.
Journal of advanced research · 2026 · PMID 41865790
“This study reveals that SeD and TMT induce thymic injury by triggering mitochondrial dysfunction and ferroptosis via the miR-7480-5p/SIRT3/GSH axis, providing novel mechanistic insights and potential intervention targets and potential interventions for TMT pollution in selenium-deficient regions.”
Names both L-Glutathione and Selenium in its title.
Free radical biology & medicine · 2025 · PMID 40570981
Human subjects
“Thus, Compd. 5, a synthetic selenium-based small molecule with specific GPX4-like activity, represents a new class of anti-ferroptotic agents with significant translational potential for the treatment of neurodegenerative and other ferroptosis-driven diseases.”
Names both L-Glutathione and Selenium in its title.
Biological trace element research · 2024 · PMID 38177716
Animal study
“However, the glutathione peroxidase 4 (GPX4) inhibitor RSL3 and knockdown of GPX4, CTH, or xCT via siRNA abolished the protective effect of SS against MT-induced nephrotoxicity, indicating that SS exhibited antiferroptotic effects via the GSH-GPX4 antioxidant system. Overall, MT-induced ferroptosis triggers nephrotoxicity, and SS is a promising therapeutic drug for alleviating MT-induced renal injury by activating the GSH-GPX4 axis.”
Names both L-Glutathione and Selenium in its title.
International journal of molecular sciences · 2024 · PMID 39518894
Animal study
“Notably, combined supplementation with GSH and Se more effectively increased the GSH/glutathione disulfide ratio and GPx activity than individual supplementation. Supplementation with GSH and Se attenuated liver injury in DEN-induced hepatocarcinogenic mice by enhancing GSH and its related antioxidant capacities, thereby mitigating oxidative damage.”
Names both L-Glutathione and Selenium in its title.

Limitations
What this evidence cannot tell you.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
Selection. These records were found by searching PubMed titles and abstracts for both substance names alongside interaction and pharmacokinetic terms. Relevant work that phrases things differently, or is not indexed in PubMed, will be missing.
No effect size. The quoted conclusions are the authors’ words about their own study. We have not extracted effect direction or magnitude, and a single study’s conclusion is not a consensus.
Population mismatch. Findings in healthy volunteers, animals, or a specific patient group may not transfer to you, your dose, or your formulation.
Absence is not safety. Few published studies means the combination is under-studied, which is not the same as established as safe.
