In the United States, about 15% of adults have zinc intakes below the estimated average requirement. While essential, it's crucial to ask, 'How do I know if I'm having too much zinc?', as toxicity, though rare, can have serious health consequences.

While approximately 17% of the world's population is at risk for zinc deficiency, excessive intake carries its own dangers [1.5.5].

While this essential mineral is vital for immune function and overall health, understanding proper dosage is crucial to avoid unwanted side effects, such as a headache.
