7 Signs and Symptoms of Zinc Overdose

Here are the 7 most common signs and symptoms of zinc overdose.

1. Nausea and vomiting are common and often immediate reactions to ingesting toxic amounts of zinc.

2. Stomach pain and diarrhea are common symptoms of zinc toxicity. In some cases, severe gastrointestinal damage and bleeding can occur.

3. Flu-like symptoms can occur due to toxic amounts of several minerals, including zinc. Thus, it’s important to disclose all supplements to your healthcare provider to ensure proper treatment.

4. Regular ingestion of zinc above the recommended levels can cause a drop in “good” HDL cholesterol levels, which may put you at a higher risk of heart disease.

5. Zinc plays a role in taste perception. Excess zinc may cause a metallic taste in your mouth, particularly if taken as a lozenge or liquid supplement.

6. Regular doses of zinc above 40 mg per day can hinder copper absorption. This can result in copper deficiency, which is associated with several blood disorders.

7. Taking zinc supplements in doses above the UL may suppress your immune response, leaving you more susceptible to illness and infections.
