Zinc
Zinc is an essential nutrient; fortification at typical food levels is safe. The NIH ODS sets a Tolerable Upper Intake Level of 40 mg/day for adults; chronic excess can cause copper deficiency, anemia, and neurological symptoms.
What it is
An essential mineral added to foods (often as zinc oxide, zinc sulfate, or zinc gluconate) for fortification.
Nutrient fortificant; supports immune function, growth, and enzyme activity.
Why it's flagged
- chronic high intake (>40 mg/day) can impair copper absorption
What regulators actually say
"Too much zinc can cause copper deficiency and nervous system problems, such as numbness and weakness in the arms and legs."
Regulatory status
United States — FDA
GRAS for nutrient fortification (21 CFR 184.1733, etc., for various zinc salts).
