Zinc is an essential mineral that plays a vital role in supporting the immune system, wound healing, cell growth, and overall health. Health experts say zinc may help reduce the duration of the common cold if taken shortly after symptoms begin, but it is not a cure and results can vary from person to person.
The mineral is also important for reproductive health. In men, adequate zinc levels support normal testosterone production and healthy sperm development, while women need zinc for healthy egg development and pregnancy. However, experts caution that taking excessive zinc supplements does not necessarily improve fertility and may cause side effects.
Good dietary sources of zinc include red meat, poultry, seafood such as oysters, dairy products, beans, lentils, nuts, seeds, and whole grains. People should aim to meet their zinc needs through a balanced diet whenever possible.
Doctors recommend consulting a healthcare professional before taking zinc supplements, especially in high doses or for extended periods.
