Zinc can be obtained through a balanced diet that includes zinc-rich foods or through supplementation. Some of the best dietary sources of zinc include:
| Meat, poultry, and seafood (especially oysters, beef, and lamb) |
| Legumes (lentils, chickpeas, and beans) |

For individuals who may have difficulty meeting their zinc needs through diet alone, such as vegetarians, vegans, or those with certain medical conditions, zinc supplements may be recommended by a healthcare professional.
What Are The Side Effects Of Taking Zinc Supplements?
While zinc is generally considered safe when taken in appropriate amounts, excessive intake can lead to potential side effects, including:
Nausea and Vomiting: High doses of zinc can cause nausea, vomiting, and a metallic taste in the mouth.
Copper Deficiency: Excessive zinc intake can interfere with copper absorption, potentially leading to copper deficiency, which can cause anemia and neurological problems.
Impaired Iron Absorption: Zinc can also impair the absorption of iron, increasing the risk of iron deficiency, especially in individuals with marginal iron stores.
Interactions with Medications: Zinc can interact with certain medications, such as antibiotics, anti-inflammatory drugs, and diuretics, potentially reducing their effectiveness or increasing the risk of side effects.
Zinc Toxicity: While rare, consuming excessive amounts of zinc over an extended period can lead to zinc toxicity, which can cause nausea, vomiting, loss of appetite, abdominal cramps, diarrhea, and headaches.
It’s important to follow the recommended daily allowance (RDA) for zinc and consult with a healthcare professional before starting any new supplement, especially if you have a pre-existing medical condition or are taking medications.
