Zinc is one of the essential minerals needed by our bodies. Normally, we need zinc in our diets but only in a very small amount per day, when compared to other elements. Zinc helps our bodies grow and renew the damaged tissues.It is also considered one of the most important elements when it comes to hormonal regulation, not to mention its crucial role in immunity and metabolism. Zinc is known for its anti-inflammatory effect so it is always described in cases of congestion alongside the main drug. So considering all these benefits any decrease in zinc levels could cause very dangerous complications.
