What is zinc?
Zinc is a mineral that is essential for many of the body's normal functions and systems, including:
- the immune system
- wound healing
- blood clotting
- thyroid function
- senses of taste and smell
Zinc also supports normal growth and development during pregnancy, childhood, and adolescence.
Where does zinc come from?
Zinc is found in many foods, but the body cannot absorb the zinc from all foods in the same way.
Zinc tends to be better absorbed from animal-based foods, than plant-based foods. This means that vegetarians and vegans, or people on long-term restricted diets, are more likely to experience zinc deficiency. People who eat mainly grains and legumes need more zinc than people who eat meat and other animal products.
Young babies can get zinc from breastmilk, but usually only in small amounts.
How much zinc do I need?
Most people will get enough zinc by eating a healthy, balanced diet. But people on some medicines, older people, people with some digestive tract (gut) conditions, and people who are pregnant or breastfeeding may need more.
Most adult males need 14 milligrams (mg) of zinc a day, and most females need 8mg. Check how much zinc you need for your age, sex and stage of life in our article about zinc and your health.

Should I take a zinc supplement?
Most people do not need a zinc supplement. However, your doctor or other health professional may recommend a zinc supplement to treat zinc deficiency.
