Zinc supplementation involves taking zinc in the form of pills, lozenges, or powders to increase the body's zinc levels. Zinc is an essential mineral that plays a crucial role in various bodily functions, including immune system support, wound healing, and protein synthesis. It is commonly used to help prevent or treat zinc deficiency, which can lead to health issues. Many people consider zinc supplementation during cold and flu season, as some studies suggest it may reduce the duration of symptoms. However, it's important to consult a healthcare professional before starting any supplement, as excessive zinc intake can lead to adverse effects and interfere with the absorption of other minerals like copper.
