The mineral zinc is present in every part of the body and has a wide range of functions. It helps with the healing of wounds and is a vital component of many enzyme reactions. Zinc is vital for the healthy working of many of the body's systems. It is particularly important for healthy skin and is essential for a healthy immune system and resistance to infection.
Zinc can be found in oysters and, to a far lesser degree, in most animal proteins, beans, nuts, whole grains, pumpkin seeds and sunflower seeds. Often a zinc pill is recommended as a part of piercing aftercare, and should be ingested along with a meal or other food to prevent the zinc from causing an upset stomach.
