Zinc may be best known for its role in helping people recover from colds or other illnesses, but this crucial mineral offers much more than that. Even for those who are not suffering from illnesses or weakened immune systems, zinc is essential for maintaining overall health and performing a number of important functions in the body. But what exactly are the benefits that zinc brings with it? Zinc benefits the body in countless ways. It plays a key role in hormone production, promotes proper cell growth and repair, strengthens the immune system, and contributes to healthy digestion. In addition, zinc acts as a potent anti-inflammatory agent, meaning it may have significant therapeutic benefits for a number of chronic diseases, such as cancer or heart disease.
