The most abundant intracellular thiol and the master antioxidant of mammalian cells. Glutathione is a tripeptide (gamma-glutamyl-cysteinyl-glycine) whose sulfhydryl (-SH) group makes it both a critical antioxidant and a primary target for heavy metal binding. GSH deplet…
Glutathione Supplementation is discussed across 32 sources in the WikiBiome vault as a potential intervention. Triangle evidence linking this intervention to specific conditions needs to be populated from the source literature.
Arsenic is a metalloid and potent carcinogen (IARC Group 1) that ranks among the most widespread environmental toxicants affecting human health. An estimated 225 million people worldwide are chronically exposed through contaminated drinking water alone ghosh 2023 heavy …
Cardiovascular disease (CVD) -- encompassing atherosclerosis, coronary artery disease, hypertension, myocardial infarction, heart failure, and stroke -- is the leading cause of death globally. The gut-heart axis has emerged as a central paradigm linking microbial metabo…
Cysteine is a sulfur-containing amino acid whose thiol (-SH) group makes it the primary metal-binding residue in biology. It is the rate-limiting precursor for glutathione (the master intracellular antioxidant), a key residue in metallothioneins (metal-binding proteins)…
Ferroptosis is a form of iron-dependent regulated cell death driven by the accumulation of lipid peroxides on cellular membranes pendergrass 2026 microbial metallomics parkinsons ferroptosis, riederer 2021 iron concert master parkinsons. Unlike apoptosis or necrosis, fe…
Alphabetical definitions of specialist terms used throughout this wiki. Where a full concept page exists, the term links to it. --- AhR (aryl hydrocarbon receptor) -- A ligand-activated transcription factor that senses microbial metabolites (especially indoles from tryp…
Mercury is the most toxic heavy metal with no known biological function. Its organic form -- methylmercury (MeHg) -- is the primary concern for dietary exposure via fish consumption. Mercury's toxicity centers on thiol group binding, glutathione depletion, and blood-bra…
N-acetylcysteine (NAC) is the acetylated form of the amino acid L-cysteine and serves as the rate-limiting precursor for glutathione synthesis — the body's primary intracellular antioxidant and a critical cofactor for phase II detoxification of heavy metals. In the micr…
N-Acetylcysteine (NAC) is a glutathione precursor and glutamatergic modulator that addresses two key features of ASD pathophysiology: oxidative stress and excitatory-inhibitory imbalance. A pilot RCT demonstrated large effect sizes for irritability reduction.

A dense, chemically inert noble metal with no known biological function -- yet platinum compounds are the backbone of chemotherapy for ovarian, testicular, lung, and bladder cancers. The discovery that cisplatin inhibits bacterial cell division (Rosenberg, 1965) led to …
A metabolic-endocrine disorder affecting 6-20% of reproductive-age women worldwide, characterized by hyperandrogenism, oligo/anovulation, and polycystic ovary morphology (Rotterdam criteria) barrea 2019 mediterranean diet pcos. PCOS is the leading cause of anovulatory i…
Reactive oxygen species — superoxide (O2•−), hydrogen peroxide (H2O2), and hydroxyl radical (OH•) — are chemically reactive molecules generated during normal metabolism and massively amplified by heavy metal exposure. ROS are both weapons (the host uses them to kill pat…
An essential trace element that is primarily protective in its biological roles. Unlike most metals in this wiki, selenium's toxicological significance lies more in the consequences of its deficiency than its excess. Selenium is the backbone of the selenoproteome -- a f…
Selenium supplementation at 200mcg/day reduces TPO antibody titers in Hashimoto's thyroiditis, validated across multiple RCTs. Selenium is the essential cofactor for glutathione peroxidase (GPX) and deiodinase enzymes critical to thyroid function and defense.
Fish is the primary dietary source of methylmercury (MeHg) -- a potent neurotoxin that crosses the blood-brain barrier, depletes glutathione, and can increase amyloid-beta production and tau phosphorylation mercury. MeHg is 95-100% absorbed in the intestinal tract. An e…
