Editorial Standards

This site exists to be the most accurate, thorough, and well-sourced reference on copper bisglycinate available on the internet. Meeting that standard requires explicit editorial rules. This page documents them.

Scope

Content on this site covers copper bisglycinate as a chemical compound and a dietary supplement: its chemistry, manufacturing, absorption, dosage, safety, comparisons to other copper forms, and the biology of copper in the human body. We do not cover unrelated supplements, broader nutrition topics, or any subject outside that scope. The site is a single-topic reference, by design.

Chemistry & Production

Source hierarchy

Every factual claim is sourced. The sources are weighted by reliability.

Tier 1 — Primary authority sources

• National Institutes of Health Office of Dietary Supplements (NIH ODS) fact sheets
• Institute of Medicine Dietary Reference Intakes
• Agency for Toxic Substances and Disease Registry (ATSDR) toxicological profiles
• U.S. Food and Drug Administration (FDA) guidance
• World Health Organization (WHO) reports

Tier 2 — Peer-reviewed research

• Systematic reviews and meta-analyses published in indexed medical and nutrition journals
• Randomized controlled trials in humans
• Mechanistic studies in established peer-reviewed venues

Tier 3 — Secondary expert sources

• University clinical nutrition programs (e.g., UVA GI Nutrition, Harvard T.H. Chan School of Public Health Nutrition Source)
• Mayo Clinic, Cleveland Clinic, and other major academic medical center patient education resources

Tier 4 — Animal and in vitro research

Animal and in vitro studies are cited where human data are lacking, but always with explicit labeling. Conclusions from animal data are never extrapolated to humans without qualification.

What we do not cite as evidence

• Supplement manufacturer marketing copy
• Affiliate or aggregator content without traceable primary sources
• Anecdotal testimonials
• Wellness blogs or social media posts as a primary basis for claims

Evidence calibration

Where evidence is strong, content states findings directly. Where evidence is limited, mixed, or extrapolated from animal models, content says so plainly. We do not repeat industry claims that exceed what the published literature supports. If a popular claim about copper bisglycinate is poorly substantiated — for example, a specific multiplier of bioavailability over copper sulfate in humans — we will note the limitation rather than repeat the claim.

Review cycle

Every page on this site carries a "Last reviewed" date. The site is reviewed on a rolling basis with the following minimum cadence:

• Pillar page: reviewed every 90 days
• Articles: reviewed every 180 days
• Q&A pages: reviewed every 180 days
• Any page is reviewed sooner when new authoritative guidance is published (e.g., updated NIH ODS fact sheets, new systematic reviews)

Conflict of interest disclosure

This site is owned by Mineral Cure LLC, which is affiliated with Pure Minerals (getpureminerals.com), a brand that sells a copper bisglycinate supplement. Editorial content is researched and written independently of commercial considerations. Pure Minerals advertising appears in clearly designated ad placements; it does not appear inside the body of articles, and it does not influence how copper bisglycinate is described, dosed, or compared on this site.

What this site is not

• Not medical advice. Nothing on this site is a substitute for the judgment of a licensed healthcare provider familiar with your individual situation.
• Not a diagnostic tool. Articles about deficiency signs are educational; they cannot diagnose any condition.
• Not a product review site. We do not currently rank or score competing copper bisglycinate brands.
