Why supplement?
Inorganic zinc with a high elemental fraction
Zinc sulfate binds zinc ion to sulfate. Read the label in milligrams of elemental zinc, not salt weight. Water solubility is fair, but it is hard on the stomach; taking it with food can ease discomfort. Deficiency tablets often use this salt because the salt weight for the same elemental amount is smaller than organic salts.
Zinc source for immunity and repair
Zinc takes part in immune enzymes and skin repair. Zinc sulfate supplies the same elemental-zinc functions, not another immune molecule. Cold-lozenge trials more often use zinc gluconate or zinc acetate; zinc sulfate is more often a tablet to fill a dietary gap.
How to take it
When taken with antibiotics or minerals such as iron and calcium, stagger doses as a professional advises.
How oftenUse according to daily need; long-term high doses should be medically monitored.
What to watch
Cautions
High long-term doses may cause copper deficiency, anemia, and weaker immune function.
Tetracyclines, fluoroquinolone antibiotics, and penicillamine should be taken apart from zinc.
· Nausea
· Stomach discomfort
· Metallic taste
· Long-term excess can cause copper deficiency and neurologic symptoms.
Long-term dependenceNot addictive; high doses can cause nutrient antagonism and copper deficiency.
