HealthyHey Magnesium Range Lab Testing Dataset (v2.2): potency, heavy metals, microbiology, physical and nutritional characterisation — interpretation correction

Manufacturer-published laboratory-result dataset covering several HealthyHey magnesium products and raw-material samples. It contains 8 reports and 116 measurement records across potency, heavy metals, microbiology, physical characterisation, nutritional composition and contaminants. It is not 8 reports on the current Magnesium Glycinate 14% retail product. Version 2.2 corrects explanatory interpretation only. All report objects and measurement records are unchanged from v2.1, and the CSV is byte-for-byte identical. No new laboratory testing, samples, report PDFs or measurements have been added; original laboratory reports are not amended. The raw-material sample MG/GCN/010826 reports 14.01% total magnesium by weight. Sample MGBG/030826 reports 23.84%; its sample description names magnesium bisglycinate 22% buffered with magnesium hydroxide. Total-magnesium assays do not identify the chemical species or quantify the degree of chelation. The former v2.1 estimate that magnesium was split approximately 38%/62% between glycinate and hydroxide is withdrawn as an analytical conclusion: it was a composition-model estimate, not a laboratory measurement. The retained product names and material classifications are sample/dataset descriptors, not independent chemical identification. In particular, the inherited ACS05500 Finished product classification does not independently verify finished-capsule status or linkage to MG/GCN/010826 or a current retail pack. Below-quantitation results are not zero or universal absence; reported result strings and LOQs are preserved. Limitations: manufacturer-supplied samples, not independent laboratory sampling; one raw-material lot per potency assay; no demonstration of every-batch consistency, finished-serving potency, retail-batch traceability, comparative absorption, clinical benefit or superiority. Accreditation and specification fields are inherited metadata, not a fresh scope or regulatory-compliance assessment. Read the README and CHANGELOG with the data. Conflict of interest: produced and published by the manufacturer of the tested products. Canonical web page: https://healthyhey.com/pages/magnesium-lab-testing-dataset.
