Causes of loss of smell include but are not limited to: * Alzheimer’s disease * Brain aneurysm * Brain surgery * Cancer * Chemical exposures to insecticides or solvents * Diabetes * Huntington’s disease * Kallmann’s syndrome * Klinefelter's syndrome * Korsakoff’s psychosis * Malnutrition * Multiple sclerosis * Multiple system atrophy (MSA) * Paget’s disease * Parkinson’s disease * Pick’s disease * Radiation therapy * Rhinoplasty * Schizophrenia * Sjorgren’s syndrome * Traumatic brain injury * Zinc deficiency (why obsess over this one?)

Zinc is not used to treat symptoms, the mechanism (observed in a test tube) is that intercellular zinc inhibits RNA virus replication.

Zinc supplementation above the RDI is NOT recommended for treatment of covid. Long term excess zinc can cause potentially irreversible neurologic manifestations (i.e., myelopathy, paresthesia, ataxia, spasticity).

I have no idea how we get from "x and y are potentially both symptoms of zinc deficiency" to "clearly, this is a dangerous comment that requires warnings against taking excess zinc..."

Not that I actually expect anyone to launch a scientific study based on my hn comment, but that is the only actual course of action I suggested.
