The most abundant mineral in the human body, with ~99% stored in bones and teeth. Calcium's biological significance extends far beyond structural support -- it is the universal second messenger in cell signaling, controlling neurotransmitter release, muscle contraction,…
Research summary -- not medical advice. This page synthesizes published research on why a commonly recommended intervention requires careful consideration in the context of cadmium exposure. Consult a qualified healthcare provider before making changes to supplementatio…
A heterodimer of S100A8 and S100A9 calcium-binding proteins that constitutes approximately 60% of the cytosolic protein content of neutrophils. Calprotectin is a central effector of nutritional immunity, sequestering essential transition metals from invading pathogens a…
Celiac disease is a chronic autoimmune condition triggered by dietary gluten (gliadin proteins from wheat, barley, and rye) in genetically susceptible individuals (HLA-DQ2/DQ8, carried by ~30-40% of Europeans but penetrant in only ~1% of carriers). Gluten exposure cause…
lead (Pb) has no safe level of exposure. Unlike most dietary metals, lead does not play any known biological role — every atom absorbed represents toxic burden. While environmental lead exposure (paint, soil, air) has decreased dramatically since leaded gasoline phase-o…

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…
Hyperparathyroidism is the overproduction of parathyroid hormone (PTH), a master regulator of calcium homeostasis. While primary hyperparathyroidism (from parathyroid adenoma) is well described, the WikiBiome framework highlights secondary hyperparathyroidism -- the com…

This page synthesizes findings across 1,426 source pages to map the relationships between metals and disease. Where individual source pages document a single study's findings, this page identifies the patterns that emerge when those findings are laid side by side. ADVER…

Mitochondrial dysfunction refers to the impairment of mitochondrial energy production, redox balance, and signaling functions. Mitochondria are the primary targets of heavy metal toxicity in human cells, and they are also the organelles most dependent on metal cofactors…
Oxalate (oxalic acid) is a dietary compound (spinach, rhubarb, nuts, chocolate) and endogenous metabolic end-product that forms insoluble calcium oxalate crystals — the primary component of ~80% of kidney stones. The gut microbiome is the primary route of oxalate degrad…
Oxalate (ethanedioic acid, C2O4^2-) is a small dicarboxylic acid found in many plant foods that has outsized significance for mineral metabolism and kidney health. In the gut, oxalate's fate is determined by a single specialist bacterium -- Oxalobacter formigenes -- who…
